A circulating tumor DNA (ctDNA) assay is an emerging non-invasive diagnostic approach providing real-time insights into the heterogeneous tumor molecular landscape of advanced prostate cancer, overcoming the limitations of traditional tissue biopsies and PSA. Detection methods include droplet digital PCR, next-generation sequencing, and new epigenomic and fragmentomic strategies (investigational) designed to improve sensitivity in cases of low ctDNA shedding. While ctDNA’s role in localized prostate cancer is limited, it offers significant prognostic value in metastatic cases, where high ctDNA levels correlate with shorter survival. Additionally, longitudinal ctDNA monitoring can predict treatment response and identify emerging resistance mechanisms, including androgen receptor alterations associated with androgen receptor pathway inhibitor therapy and BRCA reversion mutations linked to PARP inhibitors. Importantly, liquid biopsy enables genomic characterization to inform treatment decision-making, particularly in clinical scenarios where tissue biopsy is challenging, such as bone-only disease. However, the widespread clinical implementation of ctDNA analysis is hindered by several analytical challenges, including low sensitivity in localized disease and low disease burden, and the risk of false positives due to clonal hematopoiesis. Furthermore, greater efforts are required to standardize pre-analytical workflows and post-analytical data interpretation and reporting across institutions. This review aims to summarize the evolving role of cfDNA technologies in localized and advanced prostate cancer, highlighting their prognostic and predictive value and their role in uncovering mechanisms of treatment resistance.

Rationale: Oral squamous cell carcinoma (OSCC) carries a poor prognosis despite advances in multimodal therapy. Nanomedicine represents a compelling strategy to enhance targeted drug delivery and improve therapeutic outcomes. Here, we investigated sEV-mediated delivery of curcumin as a novel therapeutic approach for OSCC. Methods: Small extracellular vesicles (sEVs) were isolated from Jurkat cells by size-exclusion chromatography and loaded with curcumin via sonication to generate JCsEV. Functional effects were assessed in vitro using wound healing, transwell invasion, and metabolic activity assays across multiple cancer cell lines. Therapeutic efficacy in vivo was evaluated in the 4-nitroquinoline 1-oxide (4-NQO) immunocompetent murine model of oral carcinogenesis. Female C57BL/6J mice received intraperitoneal treatment for four weeks with PBS, free curcumin, unloaded JsEV, or JCsEV. Tumor number, tumor burden, and body weight changes were assessed at the experimental endpoint. Results: In vitro, JCsEV significantly inhibited tumor cell migration, invasion, and metabolic activity compared with controls (p < 0.05). In vivo, treatment with JCsEV significantly reduced tumor number and tumor burden in the 4-NQO model (p < 0.01). In addition, body weight loss was reduced in JCsEV-treated mice compared with controls. Conclusion: sEV-mediated delivery of curcumin effectively suppresses tumor progression in experimental OSCC. These findings establish proof-of-concept for sEV-based nanomedicine as a therapeutic strategy for OSCC and provide a compelling rationale for further translational investigation of sEVs as drug delivery platforms.

Background/Objectives: Metastatic breast cancer (MBC) remains a daunting clinical challenge, accounting for approximately 90% of all breast cancer-related deaths. The management of MBC has shifted from traditional chemotherapy to a sophisticated, biomarker-driven model of precision oncology. This evolution is predicated on the ability of biomarkers to provide prognostic and predictive information. The objective of this review is to provide a comprehensive synthesis of the current landscape of biomarker testing in MBC, detailing which biomarkers to test and the clinical rationale for doing so. Methods: This is a comprehensive review based on current international clinical practice guidelines, peer-reviewed literature, and evidence regarding clinically actionable and emerging biomarkers in metastatic breast cancer. Results: Key biomarkers currently in routine use include the established estrogen receptor (ER), progesterone receptor (PR), and HER2, alongside newer, clinically actionable alterations such as mutations in PIK3CA and ESR1, germline/somatic BRCA1/2, and PD-L1 expression. Furthermore, liquid biopsy, particularly the analysis of circulating tumor DNA (ctDNA), is rapidly gaining prominence as a non-invasive tool for real-time disease monitoring and resistance detection, highlighting the critical need for re-testing at metastasis due to tumor heterogeneity. Conclusions: The future of personalized oncology in MBC will be defined by the seamless integration of dynamic biomarkers and cutting-edge technologies. The integration of AI and spatial transcriptomics will move the field of pathology beyond a static diagnosis to a more dynamic and predictive model, reinforcing the pathologist’s role as the “molecular gatekeeper” for adaptive and personalized cancer care.

Background/Objectives: The NETest is a blood-based, machine learning-enhanced multigene transcript assay designed to detect and monitor neuroendocrine tumors (NETs). This study evaluated the accuracy of the recently validated NETest2.0® (2025) to (1) detect the presence of disease and (2) assess its utility as a clinically meaningful tool for monitoring NET status across diverse patient cohorts, including post-surgical surveillance, observation (“watch-and-wait”), and treatment settings. Methods: This registry study (NCT02270567) evaluated two objectives. For Objective 1, 1290 samples from 886 patients, of which 404 had paired follow-up samples, were analyzed for concordance between NETest2.0® and imaging-detectable disease. For Objective 2, paired blood samples (n = 404; median interval 7 months [IQR 4–13.8]) from NET patients across specialized centers were assessed. NETest2.0® scores were correlated with clinically adjudicated disease status using imaging as the comparator. Cohorts included post-surgical residual disease detection (n = 71), post-surgical recurrence monitoring (n = 44), observation (n = 72), and treatment monitoring (n = 217; somatostatin analogs, PRRT, and other therapies). Analyses were performed by cohort and in aggregate. Results: For Objective 1, NETest2.0® (cut-off ≥ 50) demonstrated an AUC of 0.96, sensitivity of 91.9%, specificity of 94.9%, PPV of 98.4%, NPV of 77.1%, and overall accuracy of 92.5%. Performance was consistent across tumor grades and sites. For Objective 2, 286 patients (70.8%) were stable, and 118 (29.2%) had progression or recurrence. NETest2.0® score changes correlated significantly with outcomes: scores decreased in stable patients (median −14.6%) and increased in progressive disease (median + 15.4%; p < 0.0001). Any increase (>0%) in score was associated with progression. Diagnostic performance for detecting progression reached a sensitivity of 78.0%, specificity of 98.3%, PPV of 91.1%, NPV of 90.2%, and accuracy of 83.9%. Conclusions: NETest2.0® accurately detects disease and provides a clinically actionable tool for monitoring NETs. Its high specificity and predictive performance support risk-adapted surveillance, potentially reducing unnecessary imaging while identifying early progression across diverse clinical settings.

With limited therapeutic progress despite aggressive multimodal treatment, glioblastoma (GBM) remains one of the deadliest primary brain tumors. Emerging evidence suggests that GSCs are key drivers of tumor initiation, intratumoral heterogeneity, therapeutic resistance, and recurrence. GSCs retain self-renewal capacity, multilineage differentiation potential, and remarkable plasticity, enabling them to adapt to diverse microenvironmental cues. These properties are upheld by dysregulated developmental and oncogenic signaling pathways, including Notch, Wnt/β-catenin, Hedgehog, PI3K/AKT/mTOR, and STAT3, as well as epigenetic and metabolic reprogramming. In addition, dedicated niches such as hypoxic and perivascular microenvironments critically support GSC maintenance and immune evasion. In this review, we summarize the current understanding of the molecular pathways governing GSC biology, examine their interactions with the tumor microenvironment, and discuss emerging therapeutic strategies targeting GSCs, including pathway inhibition, differentiation therapy, immunotherapy, and nanomedicine-based drug delivery. We highlight key challenges and future directions for translating GSC-targeted approaches into effective clinical interventions for GBM. Full article

Background: Disparities in esophageal cancer (EC) outcomes persist, partially due to inequitable access to high-quality surgical care, particularly for socioeconomically disadvantaged populations. This study evaluates the impact of social determinants of health (SDHs) on achieving textbook oncological outcomes (TOOs) and survival in operable EC patients. Methods: Using the National Cancer Database (2010–2021), we analyzed 26,367 stage I–IV A esophageal adeno- and squamous cell carcinoma patients undergoing esophagectomy after neoadjuvant chemoradiation. An SDH score (0–4) was derived from income, education, rurality, and hospital type. TOOs were defined as R0 resection, ≥20 lymph nodes examined, no 30-day mortality, and no prolonged hospitalization. Multivariable logistic and Cox regression models assessed predictors of TOOs and survival. Results: Overall, 19% achieved TOOs. Median survival time was 6.4 years for TOO+ versus 3.2 years for TOO−. Patients with favorable SDH had longer survival than those with unfavorable SDHs (median 4.0 vs. 3.5 years), but this disparity was largely confined to TOO− patients. Across stages II–III, low income and treatment at community hospitals were consistently associated with higher mortality among TOO− patients (HRs ~1.08–1.21), whereas SDH factors were largely attenuated among TOO+ patients. Stage-stratified analyses demonstrated that SDH effects were minimal in stage I and IV disease but pronounced in intermediate stages, especially in TOO− patients. Conclusions: TOOs are a powerful modifier of survival disparities in esophageal cancer. While SDH strongly influences outcomes among patients with suboptimal care pathways, achieving high-quality, textbook oncologic care attenuates these effects. Efforts to improve TOO achievement and expand access to high-quality centers may reduce socioeconomic inequities in survival. Full article

Triple-negative breast cancer (TNBC) is associated with a high risk of brain metastases (BMs). Although systemic therapies have improved extracranial disease control, the central nervous system (CNS) remains less accessible to numerous agents. As a result, this limited drug penetration makes brain metastases (BMs) remain common in TNBC, which are a leading cause of serious symptoms. This review summarizes recent key advances in triple-negative breast cancer brain metastases (TNBC-BMs), including epidemiology, prognostic stratification, biological mechanisms of CNS tropism and treatment resistance, and evolving management strategies. We discuss potential mechanisms of brain colonization, including the FOXC1-CXCR4 axis, ST6GALNAC5-related interactions with the blood–brain barrier (BBB), and the bidirectional crosstalk between metastatic cells and the brain microenvironment, particularly astrocytes and microglia. Furthermore, we evaluate the evolving clinical management, emphasizing the transition from whole-brain radiotherapy (WBRT) toward more selective local approaches such as stereotactic radiotherapy (SRS) and hippocampal sparing techniques. Concurrently, we examine the integration of CNS active systemic therapy across specific molecular subsets. This review systematically distinguishes standard-of-care interventions from investigational strategies, ultimately underscoring critical evidence gaps within the TNBC-BM landscape. Full article

Background: Segmentectomy is increasingly used and is emerging as a key treatment option for early-stage non-small cell lung cancer (NSCLC). However, questions remain regarding the adequacy of lymph node evaluation, particularly differences in N1 versus N2 dissection, and the implications for staging accuracy and adjuvant therapy. Methods: This narrative review synthesizes evidence from studies published between 2019 and 2025 comparing nodal upstaging, survival outcomes, and the role of completion lobectomy following segmentectomy versus lobectomy. Results: Twelve studies, including more than 175,000 patients, were analyzed. Lobectomy was associated with a significantly higher overall nodal upstaging rate (14.5% vs. 6.6%, p < 0.001), driven primarily by increased detection of N1 disease (13.3% vs. 3.7%, p < 0.001), while N2 upstaging rates were similar between procedures (5.5% vs. 3.2%, p = 0.07). Despite lower N1 detection, adjusted analyses reported comparable survival outcomes among patients with occult pathologic N1 (pN1) or N2 (pN2) disease who received adjuvant therapy. Segmentectomy provided outcomes comparable to lobectomy, whereas wedge resection was associated with inferior survival (HR 1.23, p = 0.042). Completion lobectomy has not demonstrated a consistent survival benefit and was associated with substantial morbidity in limited retrospective series, including high rates of thoracotomy conversion and major complications. Conclusions: When performed with systematic nodal dissection, adequate surgical margins, and appropriate adjuvant therapy, segmentectomy appears to provide survival outcomes comparable to lobectomy in selected patients with early-stage NSCLC. Completion lobectomy may not be routinely required and should be considered on a case-by-case basis within a multidisciplinary context. These findings support the use of segmentectomy in carefully selected patients when high-quality surgical staging and integrated oncologic care are ensured, while highlighting the need for prospective studies addressing occult nodal disease in the modern treatment era.

Surgical resection remains a cornerstone in the multidisciplinary management of central nervous system (CNS) tumors, particularly diffuse gliomas. Traditionally, the role of surgery has been evaluated primarily through quantitative metrics such as extent of resection and its association with survival outcomes. However, despite maximal and radiologically complete resections, recurrence remains nearly universal in malignant CNS tumors, suggesting that surgical cytoreduction alone does not fully account for post-surgical disease dynamics. Emerging biological and molecular evidence indicates that surgery represents not merely a technical intervention, but a biologically active event that profoundly reshapes tumor evolution and treatment response. In this review, we propose a conceptual framework that redefines surgery as a key biological driver in CNS tumor progression. We synthesize evidence demonstrating that surgical trauma induces inflammation, hypoxia, vascular remodeling, immune modulation, and extracellular matrix reorganization, collectively reprogramming the residual tumor microenvironment. These changes create selective pressures that favor the survival and expansion of adaptive tumor cell subpopulations, including invasive and stem-like phenotypes. From an evolutionary perspective, surgical resection functions as an acute selective bottleneck acting on heterogeneous tumor ecosystems, contributing to clonal selection and molecular divergence at recurrence. We further examine the dissociation between surgical (anatomical) margins and molecular (biological) margins, highlighting how biologically active tumor cells infiltrate beyond radiologically defined boundaries. This discrepancy provides a biological explanation for marginal and distant recurrences and challenges anatomy-based paradigms of surgical completeness. Importantly, we discuss how surgery-induced biological changes influence postoperative radiotherapy and systemic therapies, affecting radiosensitivity, target delineation, and therapeutic vulnerability. Finally, we outline future directions toward surgery-integrated precision neuro-oncology, emphasizing the potential of spatial profiling, liquid biopsy, advanced imaging, and artificial intelligence to capture perioperative tumor evolution. By reframing surgery as a biological inflection point rather than a neutral prelude to adjuvant treatment, this review advocates for a dynamic, biology-driven continuum of care aimed at anticipating tumor adaptation and improving long-term disease control in CNS tumors.

Background/Objectives: Human epidermal growth factor receptor 2 (HER2)-positive breast cancer is linked to poorer overall survival and a higher risk of brain metastases compared to HER2-negative breast cancer. Current preclinical studies lack robust HER2+ metastatic syngeneic mouse models for investigating targeted and immunomodulatory therapies. This study aims to develop effective HER2+ mouse models to investigate response dynamics to HER2-targeted therapy and immunotherapy. Methods: The human HER2 gene (WT or mutant p.A775_G776insYVMA, GFP-tagged at the C-terminus) was introduced into triple-negative breast cancer (TNBC) mouse mammary carcinoma cells with known metastatic potential (4T1 and EO771) via lentiviral transduction. HER2 expression and phosphorylation were analyzed using Western blotting and immunohistochemistry. Tumors were treated with HER2-targeted therapy (trastuzumab and tucatinib), immune checkpoint blockade (anti-PD-1 and anti-CTLA-4), and anti-HER2 antibody–drug conjugate (ADC) to evaluate treatment efficacy. Metastatic potential was assessed with brain fluorescence imaging. Statistical analysis included ANOVA and Kaplan–Meier tests. Results: Newly established lines demonstrated expression of HER2+, with HER2YVMA lines showing higher phosphorylation than HER2WT lines. Cells were tumorigenic, demonstrating in vivo tumor take rates at 100% for 4T1-HER2 and 15–30% for EO771-HER2. HER2 overexpression led to a 30% increase in spontaneous brain metastasis in the 4T1-HER2 models. Trastuzumab alone did not reduce primary tumor size but significantly reduced brain GFP signal by 17% ± 8% and 26% ± 7% in the 4T1-HER2WT and 4T1-HER2YVMA models, respectively. Combinational therapies with anti-HER2 therapy and immune checkpoint blockade effectively suppressed primary tumor growth and prolonged survival in EO771-HER2YVMA model. T-Dxd, but not T-DM1, demonstrated partial treatment response in the EO771-HER2WT model. Conclusions: HER2+ syngeneic tumor models were developed that spontaneously metastasize to the brain and demonstrate variable responses to immunotherapies and ADCs. These models are valuable for advancing molecular imaging modalities for HER2+ brain metastasis, studying blood–brain barrier penetration of HER2-targeted drugs, and exploring the combination of therapies, including immunotherapy.

Renal cell carcinomas (RCCs) driven by TFE3 rearrangement or TFEB alteration (MiT-RCC) account for up to 40% of pediatric RCCs but are rare in adults. MiT-RCC includes fusion-driven tumors with TFE3 or TFEB rearrangements (translocation RCC, tRCC) and TFEB-amplified RCC. Morphologic heterogeneity and historical exclusion from trials have limited evidence-based management. We reviewed the literature through January 2026 to summarize molecular biology, pathology, clinical behavior, and systemic therapy. MiT-RCC comprises biologically distinct entities: TFEB-rearranged tumors are often indolent in younger patients, whereas TFEB-amplified RCC, frequently co-amplifying VEGFA, behaves aggressively in older adults. In TFE3-rearranged RCC, fusion partner influences prognosis. Paradoxically, ASPSCR1::TFE3 fusions have the poorest natural history, yet fusion-annotated cohorts suggest these tumors may derive particular benefit from immune checkpoint inhibitor (ICI) plus VEGF receptor tyrosine kinase inhibitor (VEGFR-TKI) combinations. Diagnostic advances including GPNMB immunohistochemistry, TRIM63 RNA in situ hybridization, and sequencing-based fusion panels improve detection of cryptic alterations. First-line ICI + VEGFR-TKI combinations are increasingly favored for metastatic tRCC in eligible patients, while optimal management of TFEB-amplified RCC remains uncertain. Full article

Background/Objectives: Despite recent advances in breast cancer diagnostics, therapies and personalized medicine through genetic profiling, effective treatment of aggressive subtypes, particularly triple-negative breast cancer (TNBC), remains a considerable clinical challenge. MicroRNAs (miRNAs) are post-transcriptional regulators of gene expression that influence tumor progression and are detectable extracellularly in biofluids, where they are typically protected within extracellular vesicles (e.g., exosomes) or associated with RNA-binding proteins and lipoprotein complexes. This review integrates current evidence on oncogenic and tumor-suppressive extracellular miRNAs in breast cancer, with emphasis on subtype-specific functions and potential clinical relevance as liquid-biopsy biomarkers and therapeutic targets. Methods: A PubMed-based literature review (January 2000–February 2026) was conducted using search terms combining “breast cancer” with “miRNA/microRNA” and “circulating/plasma/serum/exosomal/extracellular vesicle.” Studies were prioritized if they provided validated targets/mechanisms and/or human clinical evidence for diagnostic, prognostic, or predictive utility; discrepant findings were evaluated in a subtype-aware framework. Findings were organized into functional categories (e.g., EMT/metastasis, cell-cycle/DNA damage, immune modulation, and hormone/growth factor signaling). Clinical and translational studies evaluating circulating miRNAs for diagnosis, prognosis, treatment response, and toxicity prediction were synthesized, together with key pre-analytical and analytical variables that affect reproducibility. Results: Across mechanistic and clinical studies, miR-21 and miR-155 recur as prominent oncogenic miRNAs, whereas miR-205 is frequently reported as a tumor-suppressive miRNA that is reduced in breast cancer and in circulation in several cohorts. Panels combining these miRNAs show promise for sensitive and specific breast cancer diagnostics. Additionally, several miRNAs show context- or subtype-dependent effects, with opposing activities reported between TNBC and estrogen receptor (ER)-positive disease (e.g., miR-17-92, miR-425, miR-181 family members, miR-31, and miR-24). Conclusions: Circulating miRNAs represent a promising class of minimally invasive biomarkers and potential therapeutic targets; however, translation is constrained by biological context dependence and by pre-analytical and analytical variability. Standardized protocols and rigorously validated, subtype-aware biomarker panels will be essential for clinical implementation and for enabling miRNA-informed precision oncology in breast cancer.

V-set and immunoglobulin domain-containing 1 (VSIG1) is a member of the immunoglobulin superfamily that has attracted increasing attention as a differentiation-associated protein in gastrointestinal neoplasia. Although initially described as a gastric-specific marker, accumulating evidence indicates that VSIG1 more accurately reflects gastric-enriched epithelial differentiation rather than strict anatomical origin. This conceptual shift has implications for phenotype-oriented tumor classification and diagnostic interpretation in the context of lineage plasticity. A structured and transparently reported literature search was conducted in PubMed/MEDLINE, Web of Science, and Scopus, covering studies published between 2000 and 2024. Eligible studies included original research and relevant reviews evaluating VSIG1 expression in normal tissues and digestive tract tumors, with emphasis on immunohistochemical patterns and clinicopathological correlations. In gastric cancer, VSIG1 expression consistently correlates with preserved glandular architecture and epithelial differentiation, whereas reduced or absent expression accompanies dedifferentiation and architectural disorganization. Outside the stomach, VSIG1 positivity is uncommon but reproducible in tumors exhibiting gastric-type or mixed differentiation, including settings of hepato-gastric phenotypic overlap. These patterns support interpretation of VSIG1 as a context-dependent indicator of lineage engagement and differentiation state rather than tumor origin or aggressiveness. Current data on independent prognostic value are limited and partially conflicting, and predictive roles remain unsupported, while functional data remain limited. Full article

Central nervous system (CNS) evaluation for leukemic involvement is essential both at initial diagnosis and throughout relapse surveillance in childhood acute lymphoblastic leukemia (ALL). Accurate CNS risk classification is a cornerstone of individualized chemotherapy and has significantly advanced treatment strategies. However, detecting leukemic cells in the cerebrospinal fluid (CSF) is challenging, particularly when only a small number of cells are present. While cytomorphology remains a standard diagnostic method, it is limited by low sensitivity and interobserver variability, especially in low-cellularity or equivocal samples. Flow cytometry offers superior sensitivity and specificity and is increasingly recommended to confirm or clarify ambiguous findings. Current guidelines support the use of both cytomorphologic review and flow cytometry to maximize diagnostic accuracy. Evidence consistently demonstrates that any detectable CSF blasts—even in the setting of low WBC counts—are associated with increased risk of CNS relapse and poorer outcomes, underscoring the importance of risk-adapted CNS-directed therapy. Although the prognostic significance of isolated flow-only positivity remains under study, emerging data suggest that timely therapeutic intensification may mitigate adverse outcomes. Additional modalities, including advanced flow cytometry and molecular assays, may further refine CSF assessment in the future. This review summarizes current diagnostic approaches and highlights the need for standardized protocols for CSF evaluation in pediatric ALL. Full article

Targeted therapies and chemoimmunotherapy have transformed outcomes for non–small cell lung cancer (NSCLC), yet relapse remains common. Resistance is increasingly recognized to include an early, largely reversible phase in which a minor subpopulation survives lethal therapy through non-genetic adaptation. These drug-tolerant persister (DTP) cells may be quiescent or cycling, and provide a reservoir from which stable, genetically resistant clones can later emerge. In parallel, late recurrence may reflect tumor dormancy, in which disseminated or residual cells persist for prolonged periods under microenvironmental constraint and/or immune surveillance. This review integrates DTP and dormancy frameworks in NSCLC, summarizes mechanisms that sustain persistence (chromatin and transcriptional plasticity, stress signaling, metabolic rewiring, and stromal/immune protection), and highlights experimental models and translational readouts, including circulating tumor DNA (ctDNA)–based minimal residual disease (MRD) monitoring. We also discuss potential therapeutic concepts to prevent DTP formation, exploit persister liabilities, or enforce dormancy in minimal-disease settings. A mechanistically grounded understanding of these survival programs is essential for rational combinations and biomarker-guided trials aimed at durable remission. Full article

Background and Objective: Liquid biopsy has transformed the management of advanced prostate cancer, yet its clinical role in non-metastatic disease remains uncertain. Conventional biomarkers such as PSA, imaging, and pathology have limited ability to capture minimal residual disease and biological aggressiveness. The objective of this review was to critically evaluate the current evidence on circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) in non-metastatic prostate cancer, focusing on feasibility, prognostic value, and potential clinical applications. Methods: A narrative review of PubMed-indexed original studies evaluating liquid biopsy in clinically localized or non-metastatic prostate cancer was performed. Eligible studies included patients treated with curative-intent local therapy or experiencing biochemical recurrence without radiologic metastases. Study designs were predominantly prospective or retrospective observational cohorts. Liquid biopsy analytes included CTCs and ctDNA assessed from peripheral blood plasma using EpCAM-based enrichment, targeted next-generation sequencing, whole-genome sequencing, or ultra-sensitive tumor-informed assays. Primary outcomes included detection rates, associations with clinicopathologic features, biochemical recurrence, metastasis-free survival, and overall survival. Key Findings and Limitations: Across 11 studies, CTC detection using EpCAM-based platforms was infrequent in localized disease and biochemical recurrence and showed limited prognostic value (10–11% in preoperative settings). In contrast, ctDNA was detectable in a minority of patients but consistently identified biologically aggressive disease and a higher risk of recurrence when present, particularly using tumor-informed ultra-sensitive assays. Limitations include low detection rates, heterogeneous methodologies, small sample sizes, and predominantly exploratory study designs. Conclusions and Clinical Implications: Currently, its most promising application is not broad screening, but as a selective, biology-driven tool for detecting minimal residual disease and refining risk assessment. CtDNA acts as a biological risk modifier, potentially guiding the escalation or de-escalation of adjuvant therapy. However, prospective biomarker-driven trials are required to validate these strategies before routine clinical implementation. Full article

Diffuse large B-cell lymphoma (DLBCL) is a common, aggressive non-Hodgkin lymphoma with significant molecular heterogeneity. This variability arises in part from its distinct molecular subtypes, including germinal center B-cell-like (GCB) DLBCL, activated B-cell-like (ABC) DLBCL, and primary mediastinal B-cell lymphoma (PMBL), which differ markedly in their genetic profiles, signaling pathway activities, and clinical outcomes. Although rituximab-based R-CHOP regimens have significantly improved patient outcomes, around 40% of patients still experience relapsed or refractory disease. DLBCL cells sustain their rapid proliferation through the establishment of an intricate lipid metabolism regulatory network. The interplay between this network, cell death mechanisms (e.g., ferroptosis), and the tumor immune microenvironment (TIME) significantly impacts the malignant progression of the disease and its resistance to treatment. This review summarizes recent advances in understanding the molecular mechanisms and interplay among these processes in DLBCL and discusses the clinical relevance of associated prognostic biomarkers, thus providing new insights into the development of precision therapies.

Background: B-cell maturation antigen (BCMA) directed therapies have transformed the treatment landscape for relapsed or refractory multiple myeloma (RRMM). Soluble BCMA (sBCMA), a circulating product of the membrane-bound BCMA shedding, has emerged as a potential biomarker reflecting tumor burden and disease biology. This systematic review and meta-analysis aimed to evaluate the prognostic value of baseline circulating sBCMA in patients with multiple myeloma receiving BCMA-directed therapies, with progression-free survival (PFS) as the primary endpoint. Methods: A systematic literature search of PubMed/MEDLINE, Embase, Scopus, and Web of Science databases was conducted in accordance with PRISMA guidelines. Studies enrolling patients with multiple myeloma treated with BCMA-directed therapies and reporting baseline circulating sBCMA measured in serum or plasma in relation to survival outcomes were included. Hazard ratios (HRs) for PFS and overall survival (OS) were pooled using random-effects models. Risk of bias was assessed using the QUIPS tool. Results: Four independent RRMM cohorts fulfilled the eligibility criteria and were included in the quantitative PFS meta-analysis. Elevated baseline circulating sBCMA was significantly associated with inferior PFS (pooled HR = 2.64, p < 0.05), with a consistent adverse prognostic direction across all studies. Moderate to substantial heterogeneity was observed (I2 = 63.2%), potentially reflecting differences in BCMA-directed therapy modalities across cohorts and methodological variability, including study-specific sBCMA cut-off definitions, assay procedures and sampling timepoints. Exploratory subgroup analysis suggested that the prognostic impact of baseline sBCMA on PFS may differ according to BCMA-directed therapy class. Overall risk of bias was judged as low to moderate. Conclusions: Elevated baseline circulating sBCMA is associated with inferior progression-free survival in patients with multiple myeloma treated with BCMA-directed therapies. These findings support the prognostic relevance of sBCMA as a risk stratification marker, although harmonization of assays and cut-offs and prospective validation are required before clinical implementation.

Background/Objectives: Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy with historically poor outcomes, particularly among older adults and patients harboring high-risk molecular features. Advances in genomic profiling have enabled the development of targeted therapies, reshaping treatment algorithms beyond conventional cytarabine-anthracycline induction and hypomethylating agent-based regimens. This review summarizes current evidence and emerging therapeutic strategies across four evolving areas: menin inhibition, FLT3 inhibition, IDH inhibition and treatment approaches for TP53-mutated AML. Methods: We reviewed published clinical trials, preclinical studies, and ongoing clinical trials evaluating targeted therapies in AML. Emphasis was placed on agents with regulatory approval or substantial clinical development, including menin inhibitors, FLT3 inhibitors, IDH inhibitors and novel therapies directed at TP53-mutated disease. Mechanistic data, response rates, survival outcomes, and resistance patterns were analyzed to provide an updated overview of therapeutic progress. Results: Menin inhibitors have demonstrated significant activity in NPM1-mutated and KMT2A-rearranged AML, with agents such as revumenib and ziftomenib producing meaningful remission rates and ongoing studies exploring combination strategies to mitigate resistance. FLT3 inhibitors, including midostaurin, gilteritinib, and quizartinib, have improved survival in FLT3-mutated AML, while emerging evidence supports potential benefit in selected FLT3–wild-type disease based on FLT3-like gene expression signatures. IDH inhibitors, namely ivosidenib and enasidenib, have provided increased efficacy in AML patients carrying these mutations. Questions still remain regarding their efficacy in contrast to venetoclax which has been shown to be particularly effective against this population. In contrast, TP53-mutated AML remains a therapeutic challenge: although hypomethylating-agent/venetoclax-based regimens yield improved initial responses, remissions are generally short-lived and overall survival remains poor. Early-phase therapies, including p53 reactivators and multi-kinase inhibitors, show preclinical promise but lack definitive clinical efficacy to date. Conclusions: Targeted therapies have improved outcomes in molecularly defined subsets of AML, with menin, IDH and FLT3 inhibitors representing major advances. However, TP53-mutated AML continues to carry a dismal prognosis, underscoring the need for more effective therapeutic strategies. Continued biomarker-driven research, novel drug combinations, and mechanistic insights will be essential to further refine AML treatment and improve long-term survival across disease subsets.

Background: Cancer-associated cachexia is a multifactorial metabolic syndrome characterized by progressive skeletal muscle and/or adipose tissue loss and affects approximately 40% of patients with non-small cell lung cancer (NSCLC). However, reliable circulating biomarkers for early detection and risk stratification remain undefined. Based on prior observations linking elevated circulating mitochondrial DNA (mtDNA) to cachexia, we hypothesized that mtDNA and inflammatory protein levels in plasma could predict cachexia onset and trajectories. Methods: We evaluated 27 patients with stage IV NSCLC enrolled in the SeroNet-CORALE cohort with plasma samples collected between 2020 and 2023. Forty biomarkers were quantified at two timepoints (T1 and T2) using a multiplexed MesoScale Discovery platform. Associations between log2-transformed biomarker levels and cachexia status were assessed using Firth’s penalized logistic regression. Results: Among 27 patients (65% female; mean age 65 ± 10 years; 89% adenocarcinoma histology), cachectic patients exhibited lower body mass index at both time points (T1: 21.0 ± 2.0 vs. 27.0 ± 7.0; T2: 21.8 ± 4.9 vs. 25.2 ± 4.9). At T1, cachexia was strongly associated with elevated GDF15 (OR 4.29; 95% CI 1.04–29.74; p = 0.044) and IL-15 (OR 43.83; 95% CI 2.39–>999; p = 0.007), whereas IL-4 had a protective association (OR 0.09; 95% CI 0.00–0.66; p = 0.013). At T2, cachexia was associated with higher mtDNA levels (OR 2.13; 95% CI 1.07–7.69; p = 0.022) and lower levels of IL-15, IL12/IL23p40, and MDC. Conclusions: Distinct inflammatory and mitochondrial biomarkers tracked cachexia evolution in advanced NSCLC, with early GDF-15/IL-15 elevations and later increases in circulating mtDNA. Larger longitudinal studies are warranted to validate these findings and define their clinical relevance. Full article

Taxane chemotherapy remains a durable backbone in advanced prostate cancer, but its clinical value is increasingly determined by timing, sequencing, and deliverability. We synthesize pivotal randomized trials and contemporary guidance to provide a chemotherapy-forward framework spanning metastatic castration-sensitive prostate cancer (mCSPC) and metastatic castration-resistant prostate cancer (mCRPC). In mCSPC, early docetaxel added to androgen deprivation therapy—often as part of triplet intensification with an androgen receptor pathway inhibitor (ARPI)—offers the greatest absolute benefit in fit patients with high disease burden or aggressive clinical tempo. In mCRPC, docetaxel remains foundational, while cabazitaxel is preferred over ARPI switching after prior docetaxel and one ARPI, supporting mechanism-based sequencing. Practical implementation requires proactive toxicity prevention (especially neutropenia), dose and schedule individualization, and preservation of functional status to maintain eligibility for subsequent life-prolonging therapies. Immunotherapy has a limited but important niche: sipuleucel-T may benefit selected patients with low symptom burden, whereas immune checkpoint inhibitors are best reserved for biomarker-defined subsets such as microsatellite instability-high or mismatch repair-deficient tumors; tumor mutational burden should be interpreted cautiously in prostate cancer. Ongoing trials and emerging antigen-directed platforms will clarify whether chemotherapy can act as an immune-enabling partner in defined settings. Full article

Menin inhibitors are the first targeted therapies for KMT2A-rearranged and NPM1-mutated acute leukemias, addressing a significant unmet need in these high-risk subtypes. Revumenib received approval in 2024–2025 for relapsed or refractory KMT2A-rearranged acute leukemia and NPM1-mutated AML. The AUG-MENT-101 trial reported a 23% composite complete remission rate in heavily pretreated patients, with 61% of responders achieving MRD negativity. Several menin inhibitors, including ziftomenib, bleximenib, and enzomenib, are in clinical development. They demonstrate similar efficacy, but their safety profiles differ, especially regarding QTc prolongation and coverage of resistance mutations. Combination therapies with azacitidine and venetoclax or intensive chemotherapy have achieved high response rates in newly diagnosed patients, supporting their potential use in frontline treatment. Acquired resistance, often due to MEN1 mutations at the drug-binding interface, occurs in about 40% of cases. Distinct resistance patterns among menin inhibitors suggest the possibility of sequential therapy. Approximately 30–40% of responders in relapsed or refractory trials proceeded to allogeneic transplantation, which remains a key pathway to potential cure. This review examines the molecular mechanisms of the menin-KMT2A interaction, and summarizes clinical trial data on the efficacy and safety of menin inhibitors as monotherapy and in combination.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a major cause of cancer mortality worldwide. Because HCC usually arises in cirrhotic livers, prognosis is shaped by the dual threats of tumor progression and hepatic decompensation, requiring treatment decisions that balance anticancer efficacy with preservation of liver function, portal hypertension control, and quality of life. In recent years, management has shifted from a predominantly locoregional approach to an integrated continuum that spans curative resection, ablation, and transplantation; refined transarterial and radiotherapy techniques; and modern systemic therapy dominated by immunotherapy-based combinations. These advances have improved response rates, enabled downstaging and conversion in selected patients, and expanded opportunities for sequential and multimodal treatment. However, challenges persist, including therapeutic decision-making in patients with Child–Pugh B liver function, lack of robust predictive biomarkers, and resistance after initial response. Emerging tools—liquid biopsy, radiomics, AI-assisted imaging, and microbiome modulation—may support future precision strategies and optimized treatment allocation. In this review, we summarize current evidence guiding staging and therapy selection, outline practical considerations across curative, locoregional, and systemic modalities, and discuss evolving biomarkers and next-generation immunotherapy as key steps toward more personalized, durable, and equitable global HCC care.

Burkitt lymphoma (BL) is an aggressive mature B-cell lymphoma that represents one of the most studied human malignancies. Initially described in equatorial Africa by the Irish surgeon Denis P. Burkitt, African (endemic) Burkitt lymphoma was the first human neoplasm shown to be associated with a virus, the Epstein–Barr virus (EBV), and also the first human neoplasm shown to harbor a recurrent chromosomal aberration, the t(8;14) (q24;q32) translocation that led to the identification of the central role of the MYC gene in tumorigenesis. In this review, we provide a brief historical introduction, followed by a presentation of important aspects of epidemiology, pathogenesis, and of diagnostic features including morphology, cytogenetics and molecular findings. We also provide a comprehensive overview of the findings convincingly demonstrating that subtyping of BL into EBV-positive and EBV-negative better describes the biological heterogeneity of this lymphoma entity than the historical subtyping into endemic, sporadic, and immunodeficiency-associated. As the distinction of BL from other B-cell lymphomas is important for providing optimal oncological care, we also discuss the differential diagnosis and how this lymphoma can be distinguished from other aggressive B-cell lymphomas.

Background: Breast cancers are heterogeneous in nature, including many molecular subtypes, each displaying varying characteristics in clinical outcomes as well as in responses to treatments. Subtyping requires absolute precision for the application of precision medicine; however, this is not an easy task, given the dimensionality as well as noise in miRNA expression profiles. Even though miRNAs display potential as a biological marker for subtyping breast cancers, feature selection and optimizing learning algorithms would help harness their potential as a diagnostic tool. Methods: We propose the Adaptive Hill Climbing Artificial Lemming Algorithm (AHALA), a hybrid optimization framework that integrates the global search capability of the Artificial Lemming Algorithm with an adaptive hill-climbing local search strategy. Low-variance filtering and differential gene expression analysis were first applied to reduce dimensionality and enhance biological relevance. AHALA was then used to optimize deep neural network hyperparameters for miRNA-based multi-class breast cancer subtype classification. The method was validated using TCGA breast cancer miRNA expression data and benchmarked against state-of-the-art optimization algorithms using the CEC2021 test suite. Results: AHALA had a high classification performance measure for each type of breast cancer with a mean accuracy of 95.74%, precision of 95.98%, recall of 95.74%, F1 measure of 95.74%, and AUC value of 0.9682. The new algorithm had superior convergence and significance compared with other optimization algorithms. Feature selection revealed miRNAs that belong to each subtype, such as hsa-miR-190b, hsa-miR-429, hsa-miR-505-3p, hsa-miR-3614-5p, and hsa-miR-935. Conclusions: The AHALA framework offers a potent and efficient method of performing miRNA-based subtyping of breast cancer that integrates global exploration and local search to its advantage. Its high level of classification, stability, and ability to identify biologically important biomarkers mark this method as promising. Full article

Background: Anastomotic leaks (ALs) remain a critical complication after rectal cancer surgery. Emerging evidence suggests that local immune dysregulation may play a key role in anastomotic healing. We investigated the immune microenvironment of histologically normal, tumor-adjacent rectal mucosa—a tumor-conditioned field—as a potential substrate for AL predisposition. Methods: IMMUNOREACT 4 is a sub-analysis of the IMMUNOREACT project (clinicaltrials.gov NCT04915326 and NCT04915326), a multicenter translational study evaluating immune features of histologically normal, tumor-adjacent rectal mucosa of patients undergoing colorectal anastomosis. A prospective cohort (n = 121) was analyzed using flow cytometry, in addition to a retrospective cohort (n = 262) using immunohistochemistry. Immune markers of epithelial activation and lymphocyte subsets were compared between patients with and without postoperative ALs. Exploratory predictive models combining immune and clinical variables were developed and evaluated using discrimination, calibration and decision curve analyses. Results: At flow cytometry, the CK+HLAabc+ MFI (AUC 0.66, 95% CI 0.52–0.80), CD8+CD38+ cell rate (AUC 0.65, 95% CI 0.52–0.78) and CD3+CTLA4+ cell rate (AUC 0.65, 95% CI 0.51–0.80) showed moderate predictive potential for ALs. In immunohistochemistry, CD3+ (AUC 0.57, 95% CI 0.54–0.60), CD8+ (AUC 0.57, 95% CI 0.52–0.62), CD8β+ (AUC 0.59, 95% CI 0.53–0.65) and Tbet+ (AUC 0.60, 95% CI 0.56–0.64) showed some predictive ability for ALs. The model including CD8β+, the BMI, neutrophile/lymphocyte ratio and tumor location had an AUC of 0.67 (95% CI 0.62–0.72). Conclusions: Immune activation within histologically normal, tumor-adjacent rectal mucosa—characterized by epithelial HLA upregulation and cytotoxic or Th1 T cell infiltration—is associated with postoperative ALs. Although predictive accuracy is limited, these findings support the concept that a tumor-conditioned immune microenvironment may predispose patients to impaired anastomotic healing. Integration of mucosal immune profiling with clinical variables represents a promising exploratory approach that warrants further prospective validation. Full article

Fibroblast growth factor receptor 2 (FGFR2) rearrangements represent one of the most actionable molecular alterations in biliary tract cancer, particularly in intrahepatic cholangiocarcinoma (iCCA).

Fibroblast growth factor receptor 2 (FGFR2) rearrangements represent one of the most actionable molecular alterations in biliary tract cancer, particularly in intrahepatic cholangiocarcinoma (iCCA). Approximately 10–16% of iCCA cases harbor FGFR2 fusions or rearrangements, defining a distinct molecular subtype characterized by sensitivity to FGFR-targeted therapies. Selective FGFR tyrosine kinase inhibitors, including the reversible inhibitor pemigatinib and the irreversible inhibitor futibatinib, have demonstrated clinically meaningful response rates and durable disease control in patients with previously treated FGFR2-altered iCCA, leading to regulatory approvals and the incorporation of FGFR inhibition into contemporary treatment paradigms. However, the development of acquired resistance—most commonly driven by secondary kinase-domain mutations and activation of bypass signaling pathways—remains a major limitation to sustained therapeutic benefit. This review summarizes the biological basis of FGFR2 alterations, highlights current clinical evidence supporting FGFR inhibition, and discusses the evolving landscape of resistance mechanisms. We further examine emerging therapeutic strategies aimed at overcoming resistance, including next-generation FGFR inhibitors and rational combination approaches. In addition, we highlight the growing role of circulating tumor DNA as a noninvasive tool for longitudinal molecular monitoring and treatment guidance. Together, these insights underscore the central role of FGFR2-directed therapy in precision oncology for biliary tract cancer and provide a framework for optimizing and extending targeted treatment in this molecularly defined disease subset.

Extracellular vesicles (EVs) have emerged as important messengers in cell-to-cell communication, carrying biologically active molecules such as lipids, nucleic acids, and proteins that influence both normal physiology and disease. In cancer, EVs play complex and context-dependent roles, contributing to tumor growth, angiogenesis, immune evasion, metastasis, and resistance to therapy, while in certain settings, they may also support antitumor immune responses. Increasing evidence shows that EVs released from tumor and stromal cells actively reshape the tumor microenvironment (TME) and participate in the formation of pre-metastatic niches, thereby facilitating cancer dissemination. Because EVs are stable, readily detectable in body fluids, and reflect the molecular characteristics of their cells of origin, they have attracted considerable interest as minimally invasive biomarkers for cancer diagnosis, prognosis, and treatment monitoring. In addition, their natural biocompatibility makes them attractive candidates for targeted drug delivery. This review summarizes current knowledge on EV biogenesis, cargo composition, and functional roles in cancer progression, with a particular focus on recent advances in their clinical applications. Key challenges related to EV isolation, characterization, and clinical translations are also discussed, highlighting future opportunities for integrating EV-based strategies into precision oncology.

Background: European population-based cancer registries (PBCRs) provide the foundation for monitoring skin cancer, yet registration practices and coverage vary, particularly for non-melanoma skin cancer (NMSC). Methods: We conducted a narrative review combining descriptive analyses of European Cancer Information System (ECIS) outputs with evidence from the European Network of Cancer Registries (ENCR) Working Group on NMSC and from national reports. A targeted PubMed search (2015–2025) assessed scientific usage of European registry data. Results: Nearly 200 PBCRs operate across about 40 European countries, with heterogeneous structures and timeliness. The ECIS estimated 101,500 incident cutaneous melanomas (CM) in the European Union in 2022. Long-term data from Nordic countries show a tenfold increase in CM incidence over the last six decades, with recent plateauing in younger cohorts. NMSC registration remains inconsistent: some countries record both cutaneous squamous cell carcinoma (cSCC) and basal cell carcinoma (BCC), others record cSCC only, and several omit NMSC entirely. Consequently, Europe-wide NMSC figures are not available from the ECIS. Global estimates exclude BCC and understate the true burden, which is likely between 1 and 1.6 million incident cases annually in Europe. The PubMed search identified 538 European registry-based publications on skin cancer (2015–2025). Conclusions: Melanoma registration in Europe is robust, but NMSC remains under-registered. Priorities include harmonized definitions and counting rules, better integration of outpatient and pathology data, streamlined EU-level reporting, digital/AI-enabled case ascertainment, and sentinel regions to generate reliable NMSC estimates.

Background: Radiomics has emerged as a promising approach to non-invasively characterize the molecular landscape of gliomas, providing quantitative, high-dimensional data derived from routine MRI. Given the recent shift toward molecularly driven classification, radiomics may support precision oncology by predicting key genomic, epigenetic, and phenotypic alterations without the need for invasive tissue sampling. This systematic review aimed to synthesize current radiomics applications for the non-invasive prediction of molecular biomarkers in gliomas, evaluating methodological trends, performance metrics, and translational readiness. Methods: This review followed the PRISMA 2020 guidelines. A systematic search was conducted in PubMed, Ovid MEDLINE, and Scopus on 10 January 2025, and updated on 1 February 2025, using predefined MeSH terms and keywords related to glioma, radiomics, machine learning, deep learning, and molecular biomarkers. Eligible studies included original research using MRI-based radiomics to predict molecular alterations in human gliomas, with reported performance metrics. Data extraction covered study design, cohort size, MRI sequences, segmentation approaches, feature extraction software, computational methods, biomarkers assessed, and diagnostic performance. Methodological quality was evaluated using the Radiomics Quality Score (RQS), Image Biomarker Standardization Initiative (IBSI) criteria, and Newcastle–Ottawa Scale (NOS). Due to heterogeneity, no meta-analysis was performed. Results: Of 744 screened records, 70 studies met the inclusion criteria. A total of 10,324 patients were included across all studies (mean 140 patients/study, range 23–628). The most frequently employed MRI sequences were T2-weighted (59 studies, 84.3%), contrast-enhanced T1WI (53 studies, 75.7%), T1WI (50 studies, 71.4%), and FLAIR (48 studies, 68.6%); diffusion-weighted imaging was used in only 7 studies (12.8%). Manual segmentation predominated (52 studies, 74.3%), whereas automated approaches were used in 13 studies (18.6%). Common feature extraction platforms included 3D Slicer (20 studies, 28.6%) and MATLAB-based tools (17 studies, 24.3%). Machine learning methods were applied in 47 studies (67.1%), with support vector machines used in 29 studies (41.4%); deep learning models were implemented in 27 studies (38.6%), primarily convolutional neural networks (20 studies, 28.6%). IDH mutation was the most frequently predicted biomarker (49 studies, 70%), followed by ATRX (27 studies, 38.6%), MGMT methylation (8 studies, 11,4%), and 1p/19q codeletion (7 studies, 10%). Reported AUC values ranged from 0.80 to 0.99 for IDH, approximately 0.71–0.953 for 1p/19q, 0.72–0.93 for MGMT, and 0.76–0.97 for ATRX, with deep learning or hybrid pipelines generally achieving the highest performance. RQS values highlighted substantial methodological variability, and IBSI adherence was inconsistent. NOS scores indicated high-quality methodology in a limited subset of studies. Conclusions: Radiomics demonstrates strong potential for the non-invasive prediction of key glioma molecular biomarkers, achieving high diagnostic performance across diverse computational approaches. However, widespread clinical translation remains hindered by heterogeneous imaging protocols, limited standardization, insufficient external validation, and variable methodological rigor.

Background: Colorectal liver metastases (CRLM) represent a major determinant of prognosis in patients with metastatic colorectal cancer and account for a substantial proportion of cancer-related mortality worldwide. Over the last decades, survival outcomes have improved significantly as a result of advances in systemic therapies, refinement of surgical techniques, and, most importantly, the widespread implementation of multidisciplinary management strategies. Within this evolving landscape, surgery remains the cornerstone of potentially curative treatment, although its optimal integration with systemic and locoregional therapies requires careful patient selection and individualized treatment planning. Methods: This narrative review explores the contemporary role of surgery within the multidisciplinary management of CRLM, emphasizing how surgical decision-making is integrated with medical oncology, radiology, interventional procedures, and emerging technologies. Results: The pivotal role of multidisciplinary team meetings in defining resectability, treatment sequencing, and therapeutic intent is highlighted. Key technical and oncological criteria guiding upfront resection, neoadjuvant or conversion strategies, and staged approaches are reviewed, including assessment of future liver remnant, optimization of liver volume and function, tumor burden, molecular profile, and dynamic prognostic models. In addition, the review summarizes current evidence supporting parenchyma-sparing liver surgery and the integration of local therapies such as thermal ablation, irreversible electroporation, stereotactic body radiotherapy, selective internal radiation therapy, and hepatic artery infusion chemotherapy within multimodal treatment algorithms. Complex clinical scenarios, including synchronous disease, extensive bilobar metastases, chemotherapy-associated liver injury, and the emerging role of liver transplantation in highly selected patients with liver-only disease, are also addressed. Conclusions: Modern CRLM management has evolved toward a highly individualized, biology-driven approach in which surgery is optimally integrated within a multidisciplinary framework to maximize curative potential and long-term survival.

Higher-order chromatin structures (HOCS) are fundamental to genome organization, gene regulation, and cellular homeostasis. This review examines the epigenetic mechanisms shaping HOCS, including DNA methylation, histone modifications, chromatin remodeling, and RNA-based regulatory processes. We also discuss the role of architectural proteins in maintaining chromatin topology while allowing dynamic changes to chromatin structure, thereby influencing gene expression. Growing evidence indicates that disruptions in HOCS contribute to a diverse array of human diseases, including cancer, aging-related disorders, and congenital abnormalities, primarily through aberrant gene regulation. We further discuss the concept of distinct genomic areas, in which specific chromatin regions orchestrate three-dimensional (3D) genome dynamics, positioning them as potential biomarkers and therapeutic targets. By emphasizing chromatin architecture on a global scale rather than at the level of individual genes, this review underscores its emerging relevance to precision medicine. Finally, we synthesize current technical advances, outline future directions for leveraging chromatin topology in disease diagnosis and treatment, and highlight key biological insights to reshape our understanding of genome function.

Background/Objectives: Uveal melanoma (UM) is the most common primary intraocular malignancy in adults, most commonly arising in the choroid. Its development is associated with phenotypic characteristics, ultraviolet radiation, and germline or somatic genetic alterations. Despite progress in diagnostics and local therapies, UM remains characterized by high metastatic risk and poor overall prognosis. This review aimed to summarize current knowledge on epidemiology, clinical features, genetic background, prognostic factors, and therapeutic approaches in metastatic UM. Methods: A structured literature review was conducted to evaluate epidemiological trends, genetic alterations, prognostic markers, clinical presentation, and therapeutic strategies. The results of different systemic treatments were analyzed, with special attention to liver-directed interventions and emerging systemic therapies. Results: The incidence of UM in Europe increases with latitude, ranging from two per million in the southern regions to more than eight per million in the North. The median age at diagnosis is 62 years, and most cases are detected incidentally during ophthalmological examinations due to nonspecific symptoms. Some genetic alterations serve as important prognostic indicators. Local treatment consists of globe-preserving procedures, including radiation therapy, surgery, laser therapy, or enucleation, with failure rates between 6.15% and 20.8%. Up to 70% of patients develop distant metastases, predominantly in the liver. Metastatic UM (mUM) carries a poor prognosis, with overall survival ranging from 3 to 30 months. Liver-directed therapies, particularly surgical resection, provide the most favorable outcomes. Systemic therapies demonstrate limited efficacy; however, tebentafusp has shown an overall survival benefit in HLA-A*02:01 (human leukocyte antigen A*02:01)-positive patients. Conclusions: UM is a rare but aggressive malignancy with limited treatment options once metastatic. Liver-directed strategies remain the mainstay of management, while novel systemic approaches, including tebentafusp, represent promising advances. Further research is required to improve survival and expand therapeutic opportunities. Full article

Immune checkpoint proteins including PD-1, CTLA-4, LAG-3, TIM-3, and TIGIT regulate T-cell functions, which are essential for anti-tumor immunity. Over-expression of these immune checkpoint proteins leads to T-cell exhaustion and a significant impairment of anti-tumor immunity. Rejuvenation of effector T-cell function with immune checkpoint inhibitors (ICI) restores anti-tumor immunity, which translates into clinical efficacy in the frontline and salvage treatment of various hematological malignancies. Efficacy of ICIs is highest in classical Hodgkin lymphoma, primary mediastinal large B-cell lymphoma, and NK/T-cell lymphomas, and modest in immune-privileged-site lymphomas and cutaneous T-cell lymphoma. However, in myeloid malignancies and multiple myeloma, the efficacy of ICIs remains doubtful. In addition to being used as single agents, ICIs have also been combined with other ICIs; as well as chemotherapy, antibody drug conjugates, and epigenetic agents (histone deacetylase inhibitors and hypomethylating agents). More innovative strategies include the use of ICIs in the context of allogeneic haematopoietic stem cell transplantation and chimeric antigen receptor T-cell therapy. This review synthesizes current evidence for the use of ICI in different haematological malignancies, and highlights future directions toward biomarker-driven, rationally designed therapeutic combinations.

Fenugreek (Trigonella foenum-graecum) has attracted growing interest as a complementary agent in the management of hepatocellular carcinoma (HCC), a leading cause of cancer-related mortality worldwide. Its rich botanical and phytochemical profile, including key bioactive compounds such as diosgenin, trigonelline, saponins, and flavonoids, underpins a spectrum of biological activities relevant to liver cancer therapy. This review critically examines the risks, benefits, and molecular targets of fenugreek administration in HCC, synthesising current evidence on extraction methods, standardisation, pharmacokinetics, and mechanisms of action. Preclinical studies highlight fenugreek’s antitumor efficacy, mediated by apoptosis induction, cell cycle regulation, and modulation of oxidative stress and inflammatory pathways, while its hepatoprotective effects are supported by robust antioxidant and anti-inflammatory properties. However, the safety profile is nuanced, with potential risks including reproductive toxicity, rare hypersensitivity reactions, and herb–drug interactions, particularly in patients with compromised hepatic function or polypharmacy. The review identifies critical gaps in clinical evidence, especially regarding long-term safety and synergistic effects with conventional therapies and underscores the need for rigorous standardisation and patient monitoring. We describe the potential integration of fenugreek into multimodal HCC treatment strategies, if safety concerns are addressed. Future research should elucidate precise molecular targets, optimise formulations, and conduct well-controlled clinical trials to fully realise fenugreek’s therapeutic potential in HCC management.

Background: Multidisciplinary tumor boards (MDTs) remain the foundation of gynecologic cancer management, yet increasing diagnostic complexity and rapidly evolving molecular classifications have intensified interest in artificial intelligence (AI) as a potential decision-support tool. This study aimed to evaluate the concordance between MDT-derived recommendations and those generated by ChatGPT 5.0 across a large, real-world cohort of gynecologic oncology cases. Methods: This single-center retrospective analysis included 599 consecutive patients with cervical, endometrial, ovarian, or vulvar cancer evaluated during MDT meetings over a 2-month period. Standardized anonymized case summaries were entered into ChatGPT 5.0, which was instructed to follow current ESGO guidelines. AI-generated staging and treatment recommendations were compared with MDT decisions. Discrepancies were independently assessed by two reviewers and stratified by malignancy type, disease stage, and treatment domain. Results: Overall concordance for FIGO staging was 77.0%, while treatment-related decisions demonstrated lower discordance, particularly in chemotherapy (8.2%) and targeted therapy (6.8%). The highest staging disagreement occurred in early-stage endometrial cancer (32.6%), reflecting the complexity of newly revised molecular classifications. In recurrent ovarian and cervical cancer, discrepancies were more pronounced in surgical and systemic therapy recommendations, suggesting limited AI capacity to integrate multimodal imaging, prior treatments, and individualized considerations. Vulvar cancer cases showed the highest overall agreement. Conclusions: ChatGPT 5.0 aligns with MDT decisions in many straightforward scenarios but falls short in complex or nuanced cases requiring contextual, multimodal, and patient-specific reasoning. These findings underscore the need for prospective, real-time evaluation, multimodal data integration, external validation, and explainable AI frameworks before LLMs can be safely incorporated into routine gynecologic oncology decision-making.

Background/Objectives: Mycosis fungoides (MF) and Sézary syndrome (SS) are cutaneous T-cell lymphomas (CTCLs) with variable clinical outcomes. Peripheral blood (PB) involvement in MF/SS is an independent predictor of prognosis. Accurate laboratory determination of PB involvement by MF/SS cells, however, is an ongoing challenge. Both flow cytometry (FC) and morphology-based quantification are limited by the overlap of CTCL cells and reactive T-cells. This study looks at the optimization over time of CTCL blood burden evaluation. Methods: This retrospective study reviews CTCL blood assessment at Northwestern Memorial Hospital from 2012 to 2021. Test ordering and reporting practices for morphology-based Sézary cell counts and FC were evaluated. For each assay, quantitative and qualitative results were analyzed and compared including percentages and absolute counts of abnormal T-cell populations and pathologist interpretations. Results: A total of 514 patients were evaluated, with increasing numbers of both tests ordered over time. FC quantitative metrics showed a moderate to high correlation with morphology metrics, especially for absolute CD4+/CD7− counts (correlation coefficient = 0.901, p-value < 0.001). Qualitative pathologist interpretations had moderate agreement between methods (kappa = 0.58). The recent addition of TRBC1 clonality assessment to our FC assay further optimizes the evaluation for CTCL blood burden. Conclusions: Flow cytometry offers a reliable approach for blood staging in MF/SS, and morphologic assessment may be redundant. This study provides a foundation for designing a new FC approach with TRBC1. This comprehensive review of the evolution of our laboratory practices may serve as a guide for other institutions with similar clinical needs. Full article

Cancer remains a leading cause of morbidity and mortality worldwide, and effective strategies for cancer prevention are urgently needed to complement therapeutic advances. While dietary factors are known to influence cancer risk, the molecular mechanisms that mediate inter-individual responses to nutritional exposures remain poorly defined. Emerging evidence identifies long non-coding RNAs (lncRNAs) as pivotal regulators of gene expression, chromatin organization, metabolic homeostasis, immune signaling, and cellular stress responses, the core processes that drive cancer initiation and progression and are highly sensitive to nutritional status. In parallel, advances in precision nutrition have highlighted how variability in genetics, metabolism, microbiome composition, and epigenetic landscapes shape dietary influences on cancer susceptibility. This review integrates these rapidly evolving fields by positioning lncRNAs as molecular conduits that translate dietary exposures into transcriptional and epigenetic programs governing cancer development, progression, and therapeutic vulnerability. We provide mechanistic evidence demonstrating how dietary bioactive compounds and micronutrients, including polyphenols [such as curcumin, resveratrol, epigallocatechin gallate (EGCG)], flavonoids, alkaloids such as berberine, omega-3 (ω-3) fatty acids, folate, vitamin D, probiotic metabolites (such as butyrate and propionate), and trace elements (such as selenium and zinc), modulate oncogenic and tumor-suppressive lncRNAs. These nutrient–lncRNA interactions influence cancer-relevant pathways controlling proliferation, epithelial–mesenchymal transition (EMT), inflammation, oxidative stress, and metabolic rewiring. We further discuss emerging lncRNA signatures that reflect nutritional and metabolic states, their potential utility as biomarkers for individualized dietary interventions, and their integration into liquid biopsy platforms. Leveraging multi-omics datasets and systems biology, we outline AI-driven frameworks to map nutrient–lncRNA regulatory networks and identify targetable nodes for cancer chemoprevention. Finally, we address translational challenges, including compound bioavailability, inter-individual variability, and limited clinical validation, and propose future directions for incorporating lncRNA profiling into precision nutrition-guided cancer prevention trials. Together, these insights position lncRNAs at the nexus of diet and cancer biology and establish a foundation for mechanistically informed precision nutrition strategies in cancer chemoprevention.

Triple-negative breast cancer (TNBC) is an aggressive and clinically challenging subtype of breast cancer characterized by the absence of estrogen receptor, progesterone receptor, and HER2 expression. This molecular phenotype narrows the availability of targeted therapies and contributes to high rates of early relapse, therapeutic resistance, and poor clinical outcomes. Mounting evidence pinpoints the tumor microenvironment (TME) as a central driver of TNBC progression, immune evasion, and resistance to treatment. The TME encompasses a complex and dynamic network of immune and stromal cells, extracellular matrix components, and soluble mediators that collectively shape tumor behavior and influence therapeutic response. Notably, TNBC often displays an immunologically active microenvironment, marked by high levels of tumor-infiltrating lymphocytes and immune checkpoint expression, opening a window for immune-based therapeutic strategies. This narrative review summarizes current knowledge on the cellular, molecular, and structural features of the TNBC tumor microenvironment, with particular focus on immunosuppressive mechanisms mediated by tumor-associated macrophages, myeloid-derived suppressor cells, cancer-associated fibroblasts, and dysfunctional T cells. We describe the clinical development and therapeutic impact of monoclonal antibodies, including immune checkpoint inhibitors and antibody–drug conjugates. Additionally, we discuss strategies aimed at modulating the TME to enhance monoclonal antibody efficacy, including immune cell reprogramming, extracellular matrix remodeling, cytokine/chemokine blockade, and combination treatment strategies. Finally, we highlight the role of biomarker-driven patient stratification and personalized therapeutic strategies, addressing current challenges and future directions in TME-targeted drug development. Together, these insights underscore the potential of integrating immune modulation and monoclonal antibody-based therapies to improve outcomes for TNBC patients. Full article

Background/Objectives: Hodgkin lymphoma (HL) primarily affects individuals of reproductive age, making gonadal dysfunction after chemotherapy a critical survivorship concern. While fertility preservation options including gamete and gonadal tissue cryopreservation are available before treatment, evidence-based counseling requires regimen-specific risk estimates accounting for patient age and sex. Therefore, a meta-analysis was performed to assess presumed infertility in HL patients, stratified by chemotherapy regimen, age, and sex. Methods: This systematic review and meta-analysis, conducted within the FertiTOX project, included studies published between 2000 and February 2024. Eligible studies reported gonadal function outcomes ≥ 1 year after chemotherapy, excluding patients who received pelvic radiotherapy or stem cell transplantation, or had recurrent disease. Presumed infertility was defined by surrogate markers, including amenorrhea, premature ovarian failure, or abnormal hormonal levels in women, and azoospermia, oligozoospermia, or abnormal hormonal levels in men. Results: Of 2376 screened studies, 50 were included (meta-analysis: 43 studies; 5564 female and 1631 male patients). Overall presumed infertility prevalence was 21% in women (95% CI: 0.14–0.29) and 45% in men (95% CI: 0.29–0.62). The highest prevalence occurred after BEACOPP (women 38%; men 81%), while ABVD was associated with the lowest (6% each in women and men). Childhood/adolescent HL treatment resulted in lower prevalence in women (8%) but remained high in men (67%). Conclusions: Fertility risk depends on regimen, age, and sex, requiring tailored counseling. For female children/adolescents and all patients receiving ABVD, post-treatment fertility evaluation and treatment may suffice. However, pre-treatment fertility preservation is strongly recommended for male adolescents and patients receiving other regimens. Full article

Prevention of cancer is an appealing strategy to reduce the burden of illness associated with cancer, but despite the rapidly advancing understanding of the early phases of carcinogenesis, translation of biologic insights into actionable public health strategies has been challenging. Phase III clinical trials have historically required large numbers of participants and lengthy durations to show effects in the minority of participants who develop cancer during the finite span of each trial. Early-phase trials help to refine intervention strategies and provide preliminary human safety and efficacy data to justify phase III trials. Recent advances in trial methodology and developments in immunopreventive strategies have energized the field of cancer prevention and provide potential paths for prevention of multiple cancer types. In this review we discuss the history and current state of cancer prevention trials, with a focus on overcoming inherent biologic and methodologic barriers to preventive agent development.

The tumor microenvironment (TME), composed of various immune and non-immune cells, as well as cancer stem cells, plays a critical role not only in promoting cancer cell proliferation and metastasis but also in modulating therapeutic response. A wide range of therapeutic strategies targeting the TME are currently employed in cancer treatment, including standard chemotherapy, radiotherapy, immunotherapy, anti-angiogenic therapies, agents targeting cancer-associated fibroblasts (CAFs), oncolytic viruses (OVs), cold atmospheric plasma therapy, and nanovaccines. This review provides a comprehensive overview of the influence of the TME on cancer sensitivity to these therapies across all types of solid tumors. Full article

Background/Objectives: Near-infrared photoimmunotherapy (NIR-PIT) represents a treatment approach for patients with locally advanced or recurrent head and neck cancers who are unsuitable for surgery post-standard therapy. Since its introduction in Japan in January 2021, NIR-PIT has been available exclusively under the national health insurance system, resulting in limited real-world clinical practice data. This study evaluated the association between NIR-PIT and overall survival (OS) in clinical practice. Methods: This single-center retrospective study included 45 patients with head and neck cancer who were not amenable to surgical resection owing to advanced local disease or regional recurrence without distant metastasis and who underwent NIR-PIT or systemic pharmacotherapy between January 2021 and April 2025. The primary endpoint was OS. Results: Twenty-two and 23 patients received NIR-PIT and pharmacotherapy, respectively. In the NIR-PIT group, irradiation was delivered to primary tumors in 20 patients, cervical lymph node lesions in one, and both primary and lymph node lesions in one. The median OS was 35 and 8 months, with median follow-up of 40 and 49 months in the NIR-PIT and pharmacotherapy groups, respectively. Among the NIR-PIT-eligible patients, 22 and 10 were treated with NIR-PIT and pharmacotherapy, respectively. The median OS was 35 and 8 months, with median follow-up of 40 and 24 months in the NIR-PIT and pharmacotherapy groups, respectively. Conclusions: NIR-PIT was independently associated with improved OS in patients with unresectable recurrent or metastatic head and neck cancer without distant metastasis. Prospective multicenter studies are warranted to validate these findings. Full article

Background/Objectives: Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy. The classic variant (cPTC) is characterized by indolent behavior and excellent prognosis. However, rare subtypes of PTC most often exhibit adverse clinical behavior. The aim of the study was to assess the aggressiveness of rare variants of PTC by analyzing clinicopathological characteristics (CPCs) and survival outcomes. Methods: We analyzed 80 patients with rare PTC variants treated between 2009 and 2019 who were compared with cPTC and matched with a control group for age and tumor size. The variants were categorized into high-risk (HRV: tall cell, diffuse sclerosing, columnar cell, and hobnail variants), intermediate-risk (IRV: solid variant (SV)), and low-risk (LRV: oncocytic (OV) and Warthin-like (WLV)) variants. Different CPCs (capsule and blood vessel invasion, lymphonodal metastases, microscopic and macroscopic extrathyroid extension, multifocal and bilateral presentation) and survival outcomes—overall (OS), disease-specific (DSS), and disease-free survival (DFS) were compared. Results: HRVs exhibited significantly more aggressive CPCs and worse OS, DSS, and DFS compared to cPTC (p < 0.001). IRVs showed no significant difference in CPCs or survival outcomes compared to cPTC. LRVs showed excellent survival but were associated with several unfavorable CPCs. Multivariate analysis identified classification in HRVs as the only independent predictor of recurrence (p = 0.014). Conclusions: Tumors in the HRV group should retain their status as aggressive PTC variants due to unfavorable behavior and poorer prognosis. SVs, despite earlier assumptions, do not exhibit aggressive characteristics. Although the OV and WLV have similar survival to cPTC, their potential for adverse CPCs requires caution. Full article

Recent advances in molecular pathology, driven by integrated and comprehensive diagnostic approaches, have significantly advanced precision oncology. By leveraging multiomics technologies, molecular pathology enables the simultaneous assessment of genomic alterations, transcriptomic profiles, proteomic activity, and metabolic states integrated with conventional pathological evaluation to better explain tumour biology and behaviour. Large-scale international consortia, including The Cancer Genome Atlas (TCGA) and the Clinical Proteomic Tumour Analysis Consortium (CPTAC) have systematically demonstrated the value of harmonised multiomics analyses in defining tumour subtypes, uncovering functional dependencies, and generating clinically actionable insights. Evidence from coordinated precision oncology initiatives, such as the National Cancer Institute—Molecular Analysis for Therapy Choice (NCI-MATCH) trial further indicates that treatment strategies guided by molecular pathology profiling are associated with improved clinical outcomes, including progression-free survival in molecularly selected patient populations. Consequently, molecularly stratified treatment approaches are increasingly required in routine clinical practice to enable targeted therapies for selected tumour entities. Integration of molecular data with functional and clinical outcomes has further facilitated the detection of emerging mechanisms of therapeutic resistance and heterogeneous treatment responses. Importantly, studies have shown that reliance on genomic analysis alone is insufficient to achieve optimal targeted therapy, underscoring the need for multi-layered molecular interrogation. This review highlights the biological and clinical relevance of multiomics integration, emphasising its critical role in comprehensive morpho-molecular tumour assessment and functional analyses while providing clinicians with a practical framework for interpreting integrated molecular diagnostics and addressing the methodological and translational challenges that must be overcome to enable broader implementation of precision oncology in routine practice.

Background/Objectives: (P)rehabilitation, comprising structured exercise, nutritional optimisation, and/or psychological support delivered pre- or postoperatively, has demonstrated efficacy in improving outcomes across the cancer care continuum. However, access remains limited. Technology-enabled (p)rehabilitation offers a novel solution with the potential to enhance equity and continuity of care. This systematic review aimed to evaluate the efficacy of technology-enabled (p)rehabilitation on perioperative and patient-reported outcomes among individuals undergoing thoracic and/or abdominopelvic cancer surgery. Methods: Six databases were search from inception to October 2024. Eligible studies were randomised controlled trials (RCTs) comparing technology-enabled (p)rehabilitation with usual care, placebo, or non-technology-based interventions in adults undergoing thoracic and/or abdominopelvic cancer surgery. Outcomes included postoperative complications, hospital readmissions, hospital length of stay (LOS), quality of life (QoL), pain, anxiety, depression, fatigue, distress, and satisfaction. Higher scores indicated improved QoL or worse symptom severity. Risk of bias was assessed using the revised Cochrane tool, and evidence strength was determined using GRADE methodology. Relative risks (RR) and mean differences (MD) were calculated using random-effects meta-analysis. Results: Seventeen RCTs (18 publications, n = 1690) were included. Trials most commonly evaluated application-based platforms (n = 8) and the majority exhibited some risk of bias. Technology-enabled (p)rehabilitation was associated with a significant reduction in LOS (MD = 1.33 days; 95% CI: 0.59–2.07; seven trials), and improvements in pain (MD = 6.12; 95% CI: 3.40–8.84; four trials), depression (MD = 2.82; 95% CI: 0.65–4.99; five trials), fatigue (MD = 10.10; 95% CI: 6.97–13.23; three trials) and distress (MD = 1.23; 95% CI: 0.30–2.16; single trial) compared with controls. Conclusions: Technology-enabled (p)rehabilitation shows promise in reducing LOS and improving selected patient-reported outcomes following thoracic and abdominopelvic cancer surgery. Although evidence is limited due to the small number of studies, modest sample sizes, methodological heterogeneity, and intervention variability, the overall findings justify further investigation. Large-scale, adequately powered clinical trials are required to confirm efficacy and guide clinical effectiveness and implementation studies. Full article

Background: Triple-negative breast cancer (TNBC) is more likely to metastasise to the lungs than other breast cancer (BrCa) types, yet the molecular interactions within the tumour microenvironment (TME) at secondary sites remain poorly understood. Methods: This pilot study aimed to explore the metabolic crosstalk between MDA-MB-231 TNBC cells and MRC-5 lung fibroblasts within a co-culture system to replicate the lung metastatic TME. Co-cultures were also treated with Vitamin D or Vitamin E to evaluate the effects of these nutraceuticals on the metabolic crosstalk between TNBC cells and fibroblasts. Results: Our findings demonstrate that co-culture induced the activation of fibroblasts into cancer-associated fibroblasts (CAFs), evidenced by increased α-SMA and FAP expression. Metabolic profiling revealed that TNBC cells in co-culture displayed increased expression of enzymes associated with oxidative phosphorylation (OXPHOS) and glutamine metabolism, while fibroblasts exhibited a metabolic profile consistent with glycolysis and lactate metabolism. Vitamin D inhibited lactate metabolism and HIF-1α expression in fibroblasts while suppressing TCA cycle activity in cancer cells, suggesting a potential role in disrupting oncogenic metabolic crosstalk. Conversely, Vitamin E treatment was associated with increased expression of TCA cycle and oxidative metabolism-related markers in BrCa cells without significantly affecting fibroblast glycolysis. Such differential metabolic responses may contribute to metabolic heterogeneity within the tumour microenvironment. Conclusions: These results provide valuable insights into the metabolic dynamics of TNBC metastases in the lung TME and demonstrate that Vitamins D and E exert distinct effects on metabolic crosstalk between cancer cells and fibroblasts. These findings may have significant implications for the potential supplementation of Vitamins D and E in patients with metastatic TNBC and justify further in-depth analysis. Full article

Background: Colorectal cancer (CRC) demonstrates substantial clinical and biological diversity across age groups, ancestral backgrounds, and treatment settings, alongside a rising incidence of early-onset disease (EOCRC). The mitogen-activated protein kinase (MAPK) pathway is a major driver of CRC development and therapy response; however, the distribution and prognostic value of MAPK alterations across distinct patient subgroups remain unclear. Methods: We analyzed 2515 CRC tumors with harmonized demographic, clinical, genomic, and treatment metadata. Patients were stratified by ancestry (Hispanic/Latino [H/L] vs. non-Hispanic White [NHW]), age at diagnosis (early-onset [EO] vs. late-onset [LO]), and FOLFOX chemotherapy exposure. MAPK pathway alterations were identified using a curated gene set encompassing canonical EGFR-RAS-RAF-MEK-ERK signaling components and regulatory nodes. Conversational artificial intelligence (AI-HOPE and AI-HOPE-MAPK) enabled natural language-driven cohort construction and exploratory analytics; findings were validated using Fisher’s exact testing, chi-square analyses, and Kaplan–Meier survival estimates. Results: MAPK pathway disruption demonstrated marked heterogeneity across ancestry and treatment contexts. Among EO H/L patients, FGFR3, NF1, and RPS6KA6 mutations were significantly enriched in tumors not receiving FOLFOX, whereas PDGFRB alterations were more frequent in FOLFOX-treated EO H/L tumors relative to EO NHW counterparts. In late-onset H/L disease, NTRK2 and PDGFRB mutations were more common in non-FOLFOX tumors. Distinct MAPK-associated alterations were also observed among NHW patients, particularly in non-FOLFOX settings, including AKT3, FGF4, RRAS2, CRKL, DUSP4, JUN, MAPK1, RRAS, and SOS1. Survival analyses provided borderline evidence that MAPK alterations may be linked to improved overall survival in treated EO NHW patients. Conversational AI markedly accelerated analytic throughput and multi-parameter discovery. Conclusions: Although MAPK alterations are pervasive in CRC, their distribution varies meaningfully by ancestry, age, and treatment exposure. These findings highlight NF1, MAPK3, RPS6KA4, and PDGFRB as potential biomarkers in EOCRC and H/L patients, supporting the need for ancestry-aware precision oncology approaches. Full article

Liver cancer, also known as hepatocellular carcinoma (HCC), remains a major global health concern, with high mortality driven by late-stage diagnosis, limited treatment efficacy, and frequent therapeutic resistance. Matrix metalloproteinases (MMPs), a large family of zinc-dependent endopeptidases, are central to the biological processes that drive liver tumor initiation and progression. By degrading and reorganizing extracellular matrix components, MMPs facilitate tumor expansion, tissue invasion, and metastatic dissemination. In addition, these enzymes regulate the availability of growth factors, cytokines, and chemokines, thereby influencing angiogenesis, inflammation, immune cell recruitment, and the development of an immunosuppressive tumor microenvironment. Aberrant expression or activity of multiple MMP family members is consistently associated with aggressive clinicopathologic features, including vascular invasion, increased metastatic potential, and reduced patient survival, highlighting their promise as prognostic markers and actionable therapeutic targets. Past attempts to modulate MMP activity were hindered by broad inhibition profiles and dose-limiting toxicities, underscoring the need for improved specificity and delivery strategies. Recent advances in molecular design, biologics engineering, and nanotechnology have revitalized interest in MMP targeting by enabling more selective, context-dependent modulation of proteolytic activity. Preclinical studies demonstrate that carefully tuned MMP inhibition can limit tumor invasion, enhance anti-angiogenic responses, and potentially improve the efficacy of existing systemic therapies, including immuno-oncology agents. This review synthesizes current knowledge on the multifaceted roles of MMPs in HCC pathobiology and evaluates emerging therapeutic strategies that may finally unlock the clinical potential of targeting these proteases.

Mutations in TP53 inhibit p53 protective behaviors including cell cycle arrest, DNA damage repair protein recruitment, and apoptosis. The ubiquity of p53 in genome-stabilizing functions leads to an aberrant tumor microenvironment in TP53-mutated myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Profound immunosuppression mediated by myeloid-derived suppressor cells, the upregulation of cytokines and cell-surface receptors on leukemic cells, the suppression of native immune regulator cells, and metabolic aberrations in the bone marrow are features of the TP53-mutated AML/MDS marrow microenvironment. These localized changes in the bone marrow microenvironment (BMME) explain why traditional therapies for MDS/AML, including chemotherapeutics and hypomethylating agents, are not as effective in TP53-mutated myeloid neoplasms and demonstrate the dire need for new treatments in this patient population. The unique pathophysiology of TP53-mutated disease also provides new therapeutic approaches which are being studied, including intracellular targets (MDM2, p53), cell-surface protein biologics (immune checkpoint inhibitors, BiTE therapy, and antibody–drug conjugates), cell therapies (CAR-T, NK-cell), signal transduction pathways (Hedgehog, Wnt, NF-κB, CCRL2, and HIF-1α), and co-opted biologic pathways (cholesterol synthesis and glycolysis). In this review, we will discuss the pathophysiologic anomalies of the tumor microenvironment in TP53-mutant MDS/AML, the hypothesized mechanisms of chemoresistance it imparts, and how novel therapies are leveraging diverse therapeutic targets to address this critical area of need.
