Oligometastatic breast cancer represents an intermediate state between localized and disseminated disease with reasonable potential for clinical cure. Advancements in surgery, radiotherapy, and systemic therapy have improved prognosis. Due to the high prevalence of bone metastases, an increasing number of studies are evaluating new treatment strategies for oligometastatic bone disease. The decision to perform skeletal surgery is complex and depends on optimal patient selection. Major criteria include impending or pathologic long bone fractures, severe neurologic compromise, and an expected survival of over 3 months. Factors associated with improved survival include solitary bone metastases, preserved performance status, adequate surgical margins, absence of pathologic fracture, metachronous metastases, and ER-positivity status. Radiotherapy, especially SBRT, offers effective local control and palliation. Interventional radiology techniques such as percutaneous thermal ablation have also been described as potential treatment alternatives, particularly for fragile patients. Systemic treatment varies according to the tumor subtype. For HR+ and HER2 subtypes, a combination of endocrine therapy with CDK4/6 inhibitors may be considered. HER2+ patients are often treated with HER2-targeted therapies combined with chemotherapy. For triple-negative breast cancer, chemotherapy is the primary treatment. Bone-modifying agents are also recommended to maintain bone strength, prevent skeletal-related events, and reduce the need for additional interventions. Skeletal muscle metastases in breast cancer patients are rare and typically indicate advanced disease with poor prognosis. Treatment options include chemotherapy, radiotherapy, and surgical excision, but should be tailored to the patient’s clinical condition and prognosis. Full article

The management of large bulky tumors is very challenging. The current treatment options for effective palliation of symptoms are limited. These tumors often present a large burden at the time of diagnosis, growing along critical bony and neural structures and preventing surgical resection in most of the cases. These tumors are also known to be relatively resistant to chemotherapy, with very low response rates. In addition, conventional photon-based radiotherapy has a limited effect due to their radioresistance, the use of large treatment fields, and the impossibility of delivering high doses because of the higher risk of normal tissue toxicity. Therefore, more effective radiation treatments for palliation are needed to achieve greater local control rates. A recent approach called partial ablative radiotherapy (PART) has been shown to be potentially able to improve the effectiveness of radiotherapy. This technique is based on the ability of recent advanced delivery techniques to deliver a high “ablative” dose to the central part of the tumor, maintaining a very low and safe dose profile at the periphery to spare the surrounding organs at risk. Although this technique has been evaluated only in small studies and case reports, it showed notable treatment responses and safety profiles. The present narrative review describes the rationale for PART, the current and forthcoming state of evidence, the existing studies, and the future directions for the development of this approach, including the associated challenges.

Objective: Textbook outcome (TO) is a multidimensional composite quality metric that integrates several desirable short-term outcomes into a single measure representing the “ideal” perioperative course. Unlike traditional indicators that focus narrowly on mortality or single complications, TO captures the complexity of cardiothoracic care, encompassing oncologic adequacy, absence of major complications, avoidance of reintervention and readmission, and timely discharge. Methods: In this systematic review, we synthesize evidence on the definition, incidence, determinants, prognostic impact, and limitations of TO across cardiothoracic surgery (lung and esophageal resections, lung transplantation, cardiac surgery, and adult heart transplantation) in accordance with the PRISMA guidelines. Results: Reported achievement rates range from 24% to 66% in thoracic series, 30% after Norwood palliation, 37–45% after adult heart transplantation, and 52% in a contemporary national cohort of lung transplantation, with wide between-center variability. Achieving TO is consistently associated with improved overall and disease-free survival, lower costs, and enhanced benchmarking. Determinants of failure include inadequate lymph node dissection, prolonged operative time, advanced comorbidity, pretransplant organ support, and socioeconomic disadvantage. Heterogeneity of definitions, limited incorporation of patient-reported outcomes, and equity concerns remain barriers to its successful use. Outside transplantation, benchmarking of TO in adult cardiac procedures (e.g., CABG/valve) remains limited and non-standardized. Conclusions: We argue for harmonized, procedure-specific core TO sets aligned with widely available registry fields, integration of equity-sensitive risk adjustment, and prospective validation. TO is poised to become a cornerstone metric of quality assessment and improvement in cardiothoracic surgery. Full article

Endoscopy has revolutionized the management of gastrointestinal (GI) conditions, enabling less invasive treatments for cases that once required surgery. Among these innovations, endoscopically placed stents have played a crucial role in the treatment of upper GI tract diseases for many years. Today, stents remain a valid first-line treatment for specific indications; however, advancements in endoscopic technologies have led to a reassessment of their role in some conditions. While stents are still the primary choice for palliation of malignant esophageal strictures, endoscopic vacuum therapy (EVT) has demonstrated superior outcomes for esophageal leaks, and Endoscopic UltraSonography-guided placement of lumen-apposing metal stents (LAMS) has outperformed traditional stents in gastric obstructions. This review evaluates current stent indications, highlighting upper GI conditions where they remain the best option, while also exploring emerging technologies and updated clinical guidelines to optimize patient care.

Objective: Pain response scores were evaluated by associating pain biomarkers with several parameters affecting radiotherapy (RT)-induced pain response in patients with bone metastases. Methods: A newly developed ‘revised pain and response scale’ based on standardized scales was used for pain scoring. TRPV1, β-endorphin (bEP), neurotensin (NT), and orexin A (OXA) biomarkers were determined by ELISA before and after RT. Results: Pain response rates were 44.75% (n = 47) poor response, 10.5% (n = 11) moderate response, 44.75% (n = 47) good response. NLR before RT was higher in patients with poor response than those with good response (4.0 (1.3–36.7) vs. 2.6 (1.2–11.4), respectively (p = 0.036). NLR after RT was lower in patients with good response than in patients with poor response (3.1 (1.2–10.8) and 3.9 (0.8–37.2), respectively (p = 0.047). There was a significant correlation between response scores and NT, bEP, and TRPV1. In patients with good response, NT and bEP decreased, while TRPV1 increased, both of which were significant. Pre-RT and post-RT values were, respectively, NT: 631.4 (39.7–2863.0) vs. 400.3 (79.1–1479.0) p = 0.006) and bEP: 92.1 (18.7–228.8) vs. 49.1 (13.3–135.6) p ≤ 0.001). TRPV1 values: 321.7 (48.1–1100.7) vs. 352.8 (119.3–1510.9) p ≤ 0.001). Conclusions: The study found no difference in pain response scores between the different fractionation treatments. Significant changes in NT, bEP, and TRPV1 levels were seen in patients with a ‘good response’. Pain response ratings were potentially least affected by OXA. Changes in NT, TRPV1, and bEP levels represent RT’s pain response efficacy and patients’ pain perception. These pain biomarkers may be included in guidelines as part of pain response monitoring strategies in the future. Full article

Cholangiocarcinoma (CCA) is an aggressive malignancy originating from the epithelial lining of the intrahepatic or extrahepatic bile ducts. Although rare globally, its mortality closely mirrors incidence due to late-stage presentation of the disease and limited curative options. While surgical resection and liver transplantation remain the cornerstone treatments for those with resectable disease, endoscopic techniques have emerged as versatile tools for diagnosis, therapy, and palliation. In recent years, there have been major advancements in endoscopic therapies, including radiofrequency ablation (RFA), intraluminal brachytherapy (ILBT), and photodynamic therapy (PDT). The current narrative review serves to provide an overview of current and emerging endoscopic strategies for CCA, emphasizing diagnostic capabilities, therapeutic approaches, palliative interventions, and future directions.

With increasing life expectancy, the number of older people living with comorbid diabetes and frailty is increasing. The development of frailty accelerates diabetes-related adverse outcomes. Frailty is a multidimensional syndrome with physical, mental and social aspects which is associated with increased risk of hypoglycaemia, dementia and hospitalisation. Therefore, regular screening for all aspects of frailty should be an integrated part of the care plans of older people with diabetes. In addition, every effort should be made for prevention, which includes adequate nutrition combined with regular resistance exercise training. In already frail older people with diabetes, metabolic targets should be relaxed and hypoglycaemic agents should be of low hypoglycaemic risk potential. Furthermore, the metabolic phenotype of frailty should be considered when choosing hypoglycaemic agents and determining targets. With increasing severity of frailty, proactive chronological plans of de-escalation, palliation and end-of-life care should be considered. These plans should be undertaken in a shared decision-making manner which involves patients and their families. This ensures that patients’ views, wishes and preferences are in the heart of these plans. Full article

Malignant gastric outlet obstruction (MGOO) is a serious complication arising from advanced gastric or pancreatic head cancer, significantly impairing patients’ quality of life by disrupting oral intake and inducing severe gastrointestinal symptoms. With benign causes such as peptic ulcer disease on the decline, malignancies now account for 50–80% of gastric outlet obstruction (GOO) cases globally. This review outlines the pathophysiology, evolving epidemiology, and treatment modalities for MGOO. Therapeutic approaches include conservative management, endoscopic stenting, surgical gastrojejunostomy (GJ), stomach partitioning gastrojejunostomy (SPGJ), and endoscopic ultrasound-guided gastroenterostomy (EUS-GE). While endoscopic stenting offers rapid symptom relief with minimal invasiveness, it has higher rates of re-obstruction. Surgical options like GJ and SPGJ provide more durable palliation, especially for patients with longer expected survival. SPGJ, a modified surgical technique, demonstrates reduced incidence of delayed gastric emptying and may improve postoperative oral intake and survival compared to conventional GJ. EUS-GE represents a promising, minimally invasive alternative that combines surgical durability with endoscopic efficiency, although long-term data remain limited. Treatment selection should consider patient performance status, tumor characteristics, prognosis, and institutional resources. This comprehensive review underscores the need for individualized, multidisciplinary decision-making to optimize symptom relief, nutritional status, and overall outcomes in patients with MGOO.

Osteoarthritis (OA) remains a major contributor to pain and disability; however, the current management is largely reactive, focusing on symptoms rather than preventing irreversible cartilage loss. This review first examines the mechanistic foundations for pharmacological chondroprotection—illustrating how conventional agents, such as glucosamine sulfate and chondroitin sulfate, can potentially restore extracellular matrix (ECM) components, may attenuate catabolic enzyme activity, and might enhance joint lubrication—and explores the delivery challenges posed by avascular cartilage and synovial diffusion barriers. Subsequently, a practical “What–How–When” framework is introduced to guide community pharmacists in risk screening, DMOAD selection, chronotherapeutic dosing, safety monitoring, and lifestyle integration, as exemplified by the CHONDROMOVING infographic brochure designed for diverse health literacy levels. Building on these strategies, the P4–4P Chondroprotection Framework is proposed, integrating predictive risk profiling (physicians), preventive pharmacokinetic and chronotherapy optimization (pharmacists), personalized biomechanical interventions (physiotherapists), and participatory self-management (patients) into a unified, feedback-driven OA care model. To translate this framework into routine practice, I recommend the development of DMOAD-specific clinical guidelines, incorporation of chondroprotective chronotherapy and interprofessional collaboration into health-professional curricula, and establishment of multidisciplinary OA management pathways—supported by appropriate reimbursement structures, to support preventive, team-based management, and prioritization of large-scale randomized trials and real-world evidence studies to validate the long-term structural, functional, and quality of life benefits of synchronized DMOAD and exercise-timed interventions. This comprehensive, precision-driven paradigm aims to shift OA care from reactive palliation to true disease modification, preserving cartilage integrity and improving the quality of life for millions worldwide.

Pancreatic cancer is an aggressive malignancy, with a current 5-year survival rate in the United States of approximately 13.3%. Although the current standard for resectable pancreatic cancer most commonly includes neoadjuvant chemotherapy prior to a curative resection, surgery, in the majority of patients, has historically been palliative. The latter interventions include open or laparoscopic bypass of the bile duct or stomach in cases of obstructive jaundice or gastric outlet obstruction, respectively. Non-surgical interventional therapies started with percutaneous transhepatic biliary drainage (PTBD), both as a palliative maneuver in unresectable patients with obstructive jaundice and to improve liver function in patients whose surgery was delayed. Likewise, interventional radiologic techniques included the placement of plastic and ultimately self-expandable metal stents (SEMSs) through PTBD tracts in patients with unresectable cancer as well as percutaneous cholecystostomy in patients who developed cholecystitis in the context of malignant obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) and stent placement (plastic/SEMS) were subsequently used both preoperatively and palliatively, and this was followed by, or undertaken in conjunction with, endoscopic gastro-duodenal SEMS placement for gastric outlet obstruction. Although endoscopic ultrasound (EUS) was initially used to cytologically diagnose and stage pancreatic cancer, early palliation included celiac block or ablation for intractable pain. However, it took the development of lumen-apposing metal stents (LAMSs) to facilitate a myriad of palliative procedures: cholecystoduodenal, choledochoduodenal, gastrohepatic, and gastroenteric anastomoses for cholecystitis, obstructive jaundice, and gastric outlet obstruction, respectively. In this review, we outline these procedures, which have variably supplanted surgery for the palliation of pancreatic cancer in this rapidly evolving field. Full article

Background: Patients with single right ventricular morphology (SRV) may exhibit impaired function with increased morbidity, mortality, and need for cardiac transplant due to progressive SRV failure after the Fontan procedure. The aim of the study was to longitudinally characterize the cardiac mechanics and trajectory of disease evolution of SRV failure in Fontan patients. Methods: We performed a case-controlled longitudinal study of 52 patients who underwent extracardiac Fontan palliation for SRV between 1994 and 2015 and compared echocardiographic measures of right ventricular (RV) function, RV-systemic vascular coupling and ventricular remodeling between patients who required heart transplants due to SRV failure (study group, n = 26) and those who did not (control group, n = 26). To define the trajectory, measurements were obtained at four matching time points equivalent in duration from Fontan. Results: RV circumferential shortening function declined in both groups over the time period, but was significantly lower (p < 0.01) in the study group farther from the Fontan. RV-systemic vascular coupling, assessed by systolic time interval measures and RV work, was preserved in the control group, but significantly altered (p < 0.001) in the study group. Relative wall thickness decreased, and the minor/major-axis ratio, as an index of ventricular geometry, increased in the study group, but both remained stable in the control group. Conclusions: This study suggests that positive ventricular remodeling with enhanced circumferential systolic function, and preserved RV-vascular coupling, appear to be adaptive and protective mechanisms against RV failure in Fontan with SRV. These indices of cardiac mechanics may serve as clinically relevant quantifiable markers of disease evolution, and early indicators for therapeutic intervention. Full article

Background/Objectives: Colorectal cancer (CRC) is the most common gastrointestinal (GI) malignancy, the second leading cause of cancer-related mortality, and the third most prevalent tumor. Around 20% of cases are metastatic or inoperable at diagnosis, often requiring palliative treatment, which may not be feasible in frail patients. Calcium-electroporation, a less invasive alternative, induces cell death via apoptosis, necrosis, and pyroptosis. This study is the first in the United Kingdom to evaluate the efficacy and safety of endoscopic calcium-electroporation in palliating distal CRC. Methods: Frail patients with inoperable left-sided CRC were included. The diagnosis and staging followed standard guidelines, while frailty was assessed using the performance status (PFS), Charlson comorbidity index (CCI), and American Society of Anesthesiologists (ASA) score. Calcium electroporation was performed via a flexible endoscopy usually under sedation, with symptom relief, quality of life (QoL), survival, and adverse events (AE) monitored. Results: Sixteen patients (median age 84.5) underwent 36 treatments with electroporation over 28 months (November 2022 to March 2025). The incidence of common symptoms was rectal bleeding (75%), constipation (25%), and pain (75%). Nine patients had metastases and three had failed conventional treatments. Symptomatic relief and an improved QoL occurred in 86.7%, with transfusion/iron infusion needs reduced by 91.7%. The median cancer-specific survival was 10 months, with a 94% survival rate. No device-related AE was recorded. One patient died after 11 months due to disease progression while two patients passed away from other medical conditions. Conclusions: Endoscopic calcium electroporation is a safe, palliative option effective for tumor reduction and symptomatic relief in frail CRC patients unfit for conventional therapies. Full article

Glioblastoma (GBM, isocitrate dehydrogenase wild-type) is the most common primary malignant brain tumor in adults and is associated with a severely low survival rate. Treatments offer mere palliation and are ineffective, due, in part, to a lack of understanding of the intricate mechanisms underlying the disease, including the contribution of the tumor microenvironment (TME). Current GBM models continue to face challenges as they lack the critical components and properties required. To address this limitation, we developed innovative and practical three-dimensional (3D) GBM models with structural and mechanical biomimicry and tunability. These models allowed for more accurate emulation of the extracellular matrix (ECM) and vasculature characteristics of the native GBM TME. Additionally, 3D bioprinting was utilized to integrate these complexities, employing a hydrogel composite to mimic the native environment that is known to contribute to tumor cell growth. First, we examined the changes in physical properties that resulted from adjoining hydrogels at diverse concentrations using Fourier-Transform Infrared Spectroscopy (FTIR), compression testing, scanning electron microscopy (SEM), rheological analysis, and degradation analysis. Subsequently, we refined and optimized the embedded bioprinting processes. The resulting 3D GBM models were structurally reliable and reproducible, featuring integrated inner channels and possessing tunable properties to emulate the characteristics of the GBM ECM. Biocompatibility testing was performed via live/dead and AlamarBlue analyses using GBM cells (both commercial cell lines and patient-derived cell lines) encapsulated in the constructs, along with immunohistochemistry staining to understand how ECM properties altered the functions of GBM cells. The observed behavior of GBM cells indicated greater functionality in softer matrices, while the incorporation of hyaluronic acid (HA) into the gelatin methacryloyl (gelMA) matrix enhanced its biomimicry of the native GBM TME. The findings underscore the critical role of TME components, particularly ECM properties, in influencing GBM survival, proliferation, and molecular expression, laying the groundwork for further mechanistic studies. Additionally, the outcomes validate the potential of leveraging 3D bioprinting for GBM modeling, providing a fully controllable environment to explore specific pathways and therapeutic targets that are challenging to study in conventional model systems.

Staged palliation with the creation of a Fontan circulation is the standard surgical approach in patients with a single ventricle. The Fontan circulation is a complex circuit that is associated with various complications that may present early or later in life and can limit life quality and expectancy. In this context, a good understanding of the Fontan physiology is important to improve outcomes for single-ventricle patients. Cardiovascular magnetic resonance (CMR) is recommended for the long-term follow-up of Fontan patients, as it provides functional and haemodynamic information. Four-dimensional (4D) Flow MRI is a time-resolved, three-dimensional, velocity-encoded cardiovascular magnetic resonance technique that is increasingly used in Fontan patients because it not only enables measuring blood flow within a three-dimensional (3D) volume, but also allows for assessing more advanced haemodynamic parameters that may help in understanding the Fontan physiology and pathophysiology. Furthermore, 4D Flow is used for image-based simulations using computational fluid dynamics. In this review, we provide an overview of the use of cardiovascular magnetic resonance flow assessment, with a focus on four-dimensional flow (‘4D Flow’). Full article

Background: Keratinocyte carcinomas, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), presents a growing concern. Electrochemotherapy (ECT), an emerging treatment modality, combines chemotherapy and electroporation to enhance drug delivery into cells. However, reviews evaluating ECT in keratinocyte carcinomas are lacking. Objectives: This study reviews the efficacy and toxicity of ECT in the treatment and palliation of keratinocyte carcinomas. Methods: A systematic search was conducted across PubMed, Cochrane, Embase, and Scopus databases. Patient, tumor, and treatment characteristics, tumor response, long-term disease outcomes, and toxicity data were extracted. Quality of studies was assessed using validated tools. Primary endpoints included tumor response; secondary endpoints included long-term disease outcomes and toxicity. Results: Twenty-one studies were included. Complete response (CR) rates ranged from 50 to 100% and from 10 to 100% for BCC and SCC, respectively. OS rates ranged from 95 (14 months) to 100 (1 year) % and from 64 (1 year) to 85.1 (8.6 months) % for BCC and SCC, respectively. One-year local disease-free survival (LDFS) rates were 89% and 87% for BCC and SCC, respectively. For BCC, local progression-free survival (LPFS) rates were 96% (1 year), 90% (2 year), and 70% (5 year). For SCC, 1-year LPFS rates were 80% on a per-patient basis and 49% on a per-lesion basis. Conclusions: ECT is effective and tolerable in the treatment and palliation of keratinocyte carcinomas. Future studies should focus on improving reporting quality, optimizing treatment protocols, and investigating long-term outcomes. Full article
