Lymphoedema is a chronic and dynamic condition that requires the investment of time and resources to appropriately manage. It fluctuates in response to illness, activity, and age, as well as in response to environmental conditions. This qualitative study explored the impact of the climate and climatic variations on lymphoedema. Focus groups were completed with patients (n = 12) and therapists (n = 7) to explore, in depth, their experiences of managing lymphoedema throughout the year. The results suggested that heat and humidity definitely alter the severity of lymphoedema, and a range of individual strategies are required in order to control symptoms. Central to effectively managing lymphoedema is the notion that every body is different and every lymphoedema is different, and therefore understanding one’s own body, what it needs, and what resources are available is essential in maintaining lymphoedema in the face of climate change.

Compression is the cornerstone of treatment for lymphoedema; however, in patients with Stage III lymphoedema that causes a significant alteration of limb shape and size, additional creative problem solving is required in order to find a solution that fits the person, their limb and their personal circumstances. Medical adaptive compression (MAC) systems provide solutions to complex situations. We present two cases of individuals who completed an inpatient rehabilitation stay for intensive treatment of their lymphoedema and were fitted with MAC devices to ensure long-term success.

Complex atypical endometrial hyperplasia (CAH) carries a high probability of cancer. The intraoperative evaluation of endometrial cancer in cases of CAH has not been reliable. The safety and sensitivity of sentinel lymph node (SLN) sampling has been validated. In our study, we aimed to evaluate the efficacy and safety of SLN sampling in CAH managed by the da Vinci robotic platform. A total of 113 patients with a preoperative diagnosis of CAH were included in this retrospective cohort study. All of them underwent a robot-assisted total laparoscopic hysterectomy and bilateral salpingo-oophorectomy, with 69 patients undergoing SLN sampling. A statistical analysis calculated the probability of cancer, the SLN map rate, and surgical complications. The predictors of cancer were evaluated. Descriptive statistics were used to summarize the results; comparative statistics were used to compare the cohorts; and logistical regression analysis was used to predict the risk. Forty-seven percent of the entire cohort was diagnosed with endometrial cancer. The median age was 63 years in the SLN cohort (N = 69) and 61 in the No-SLN cohort (N = 44) (p = 0.363). The median BMI was 34 Kg/m2 in the SLN cohort and 40 in the No-SLN cohort (p = 0.004). The bilateral SLN map was 92.8%, and the unilateral SLN map rate was 7.2%. There were no grade-3–4 complications in the SLN cohort, and four grade-3–4 complications in the No-SLN group (p = 0.021). A preoperative diagnosis of CAH bordering on or unable to rule out cancer was the only predictor of cancer. Sentinel lymph node sampling has a high map rate and low complications in CAH. We recommend a prospective study investigating the clinical benefit of the procedure.

The studies of thymic structure were performed predominantly in cohorts of younger individuals. Here, we established a cohort of body donors whose age at the time of death ranged from 57 to 103 to study the relationship between thymic structure and factors that, in the younger subjects, have shown to affect the organ’s anatomy, including the presence of the organ’s capsule, its weight, size of the left and right lobes, and a transverse diameter. We explored the relationships between these thymic parameters and the subjects’ age, sex, and cause of death (COD), asking how the thymus in the elderly differed from the organ’s macro-anatomy in a broader and younger human population, and whether age, sex, COD, and BMI could influence the thymic parameters in the elderly. Our analyses revealed that the thymic size but not thymic weight in the KYCOM cohort differed significantly from the younger individuals. The size of the thymus in males progressively decreased, but in females, the size of the right lobe increased. The encapsulated thymus was detected with a higher frequency in females than males. We found no associations between thymic parameters and the person’s COD, age, or sex. However, the person’s BMI was associated with thymic weight, suggesting that obesity may influence the aging of the immune system.

CLL B cells express elevated pro-survival BCL2, and its selective inhibitor, venetoclax, significantly reduces leukemic cell load, leading to clinical remission. Nonetheless, relapses occur. This study evaluates the hypothesis that progressively diminished BCL2 protein in cycling CLL cells within patient lymph node niches contributes to relapse. Using CFSE-labeled, purified CLL populations known to respond with vigorous cycling in d6 cultures stimulated with TLR9-activating ODN (oligodeoxynucleotide) + IL15, we show that BCL2 protein progressively declines during consecutive cell divisions. In contrast, MCL1 and survivin are maintained/slightly elevated during cycling. Delayed pulsing of quiescent and activated CLL cultures with selective inhibitors of BCL2 or survivin revealed selective targeting of noncycling and cycling populations, respectively, raising implications for therapy. To address the hypothesis that BCL2-repressive miRs (miR15a/miR16-1), encoded in Chr13, are mechanistically involved, we compared BCL2 protein levels within ODN + IL15-stimulated CLL cells, with/without del(13q), yielding results suggesting these miRs contribute to BCL2 reduction. In support, within ODN-primed CLL cells, an IL15-driven STAT5/PI-3K pathway (required for vigorous cycling) triggers elevated p53 TF protein known to directly activate the miR15a/miR16-1 locus. Furthermore, IL15 signaling elicits the repression of BCL2 mRNA within 24 h. Additional comparisons of del(13q)+ and del(13q)−/− cohorts for elevated p53 TF expression during cycling suggest that a documented miR15a/miR16-1-mediated negative feedback loop for p53 synthesis is active during cycling. Findings that robust CLL cycling associates with progressively decreasing BCL2 protein that directly correlates with decreasing venetoclax susceptibility, combined with past findings that these cycling cells have the greatest potential for activation-induced cytosine deaminase (AICDA)-driven mutations, suggest that venetoclax treatment should be accompanied by modalities that selectively target the cycling compartment without eliciting further mutations. The employment of survivin inhibitors might be such an approach.

The foot and calf muscle pump, collectively known as the venous muscle pump, plays a crucial role in the circulatory system (veins, arteries, and lymphatics), particularly in the return of blood from the lower extremities to the heart. Further, the venous muscle pump is crucial to lymphatic health and essential in chronic edema/lymphedema management. This article will highlight the significance of the venous pump and review the functional anatomy and physiology of the foot and calf, integrating the connection to venous and lymphatic health. The complementary importance of mobility, exercise, and breathing will also be explored.

Hodgkin’s lymphoma (HL) is a monoclonal lymphoid neoplasm that is mainly characterized by multinucleated Reed–Sternberg cells on a background of non-neoplastic inflammatory cells. The incidence rate of Hodgkin’s lymphoma is 2.5 new cases per 100,000 people per year (1). Paraneoplastic syndromes are conditions that are related to malignancy; however, they are not a result of tumor invasion or compression of malignant tissues. These paraneoplastic syndromes can occur virtually at any point in the disease course, and paraneoplastic syndromes in HL and their various forms are not well studied. In this review article, we will be discussing paraneoplastic syndromes in general and then delve into specific syndromes seen in HL, followed by a brief discourse regarding their early recognition and timely management.

Anti-CD20 monoclonal antibodies (mAbs) have revolutionized the treatment of lymphomas by improving the survival of patients, particularly in conjunction with chemotherapy. Until recently, the gold standard was based on the utilization of Rituximab (RTX) combined with chemotherapy. With our better understanding of monoclonal antibody (mAb) engineering, anti-CD20 mAb therapy has evolved to enhance clinical outcomes by improving pharmacokinetics, safety, activity and immunogenicity. Efforts to improve the on-targeting CD20 expressed on lymphomas through novel bioengineering techniques have led to the development of newer anti-CD20 mAbs that have accentuated complement-dependent cytotoxicity (CDC), antibody-dependent cell medicated cytotoxicity (ADCC), and/or a direct killing effect. There are several anti-CD20 monoclonal antibodies that have been evaluated for the treatment of lymphomas, some of which are now approved in addition to RTX.

Radiation therapy is a key contributor to positive outcomes in hematological malignancies. However, this is contingent on minimizing the exposure of critical normal organs. The introduction of computed tomography (CT) for radiation treatment planning and the development of sophisticated dose calculation algorithms has transformed the radiation therapy field and made it possible to transition from conventional involved-field radiation to modern involved-site radiation therapy. Thanks to rapid advances in drug discovery, treatment strategies for many hematological malignancies have evolved to incorporate targeted and cellular therapies, in some cases even allowing the replacement of chemotherapy. As a result, new opportunities have been created for radiation to address relapses after more lines of therapy, identify disease-involving sanctuary sites, and bridge to the subsequent therapy. When considering radiation in patients receiving novel therapies, who may also be more heavily pretreated, respecting the critical and normal structures at all costs is imperative. In this document, we will describe modern techniques used to deliver state-of-the-art radiation therapy and practical considerations to ensure the accurate treatment of the target while avoiding normal organs at risk.

Radiotherapy and/or chemotherapy have been used for nearly 100 years to treat lymphoma. Recently, immunotherapy has been incorporated into the treatment of lymphomas. Here, we will review both the role of immunotherapy in lymphoma as well as the feasibility of incorporating immunotherapies with conventional lymphoma treatments, especially radiotherapy. Immunotherapy agents include checkpoint inhibitors that target the PD-1/PD-L1 axis, CTLA-4, or CD47. In addition, other immunotherapy agents such as bi-specific antibodies and CD19 CAR-T cell therapy are being implemented in various non-Hodgkin’s lymphomas. Extrapolating from observations in other disease sites and incorporating immunotherapy with conventional treatments of lymphoma, including radiotherapy, may have opposing effects. Radiotherapy may stimulate anti-tumor immune responses that synergize with immunotherapies. In contrast, radiotherapy, as well as chemotherapy, may also induce local and systemic immune dysfunction which reduces the efficacy of immunotherapies. With newer radiation treatment techniques and limited radiation fields, it is likely that the efficacy of immunotherapy can be maintained when included with conventional treatments. Therefore, there remains an unmet need to better understand the role of immunotherapy alone and in combination with current treatments in lymphoma patients.

Radiation therapy has been proven to be highly effective in the treatment of lymphoma. With increasing rates of long-term survival, the reduction in toxicity has gained importance. The evolving understanding of the diseases’ biology, as well as technical and conceptual advances, allows for a precise and individualized application of irradiation. Smaller treatment fields and safety margins make it possible to spare healthy neighbouring tissue (organs at risk). The International Lymphoma Radiation Oncology Group (ILROG) has developed several guidelines to optimize radiotherapy treatment in lymphoma patients. Since its introduction in 2013, involved site radiotherapy (ISRT) has been adopted as the standard of care in most treatment regimens in adult lymphoma. This article serves as a summary of the current ILROG guidelines, also considering contemporary developments and possible future directions.

Non-Hodgkin lymphomas (NHLs) represent a diverse group of hematologic malignancies derived from various cells. B-cell NHLs represent the largest fraction of lymphomas diagnosed and treated in the United States. Standard chemo-immunotherapies with rituximab and multiagent cytotoxic regimens have proven to be effective in the management of these lymphoproliferative neoplasms; nonetheless, a considerable fraction of patients still experience relapse or have treatment-refractory disease. Therapeutic advances using novel immunotherapeutic agents as well as cell-based treatments, such as chimeric antigen receptor (CAR) T-cell therapies, have improved the outcomes of relapsed/refractory (R/R) B-cell NHL. Most of these new treatment strategies are not curative and most patients succumb to R/R disease, leaving this population with an unmet need for effective and well-tolerated therapeutic options. One of these up-and-coming options are bispecific antibodies (BsAb), either as single agent or in combination with other medications. Conclusion: BsAbs offer a novel “off the shelf” chemotherapy-free approach in the management of R/R B-cell NHL. Advancements in antibody construct design along with improved safety profile and clinical effectiveness of the most recent BsAbs suggest that these agents are a promising new option in the management of R/R B-cell NHL.

Under inflammatory conditions including lymphatic disorders, bone marrow-derived myeloid cells often express lymphatic endothelial cell (LEC) markers, and these cells are then called LEC progenitor cells, which extend lymphatic vessels by fusing with existing lymphatic vessels. However, studies on the mechanism of lymphatic regeneration using three-dimensional images of lymphatic structures are limited. In this study, scanning electron microscopy (SEM) was used to observe the three-dimensional structure of lymphangiogenesis in a mouse model of secondary lymphedema. The model was established in C57BL/6J mice via circumferential incision in the inguinal region of the left hind limb. Skin samples were obtained from the lymphedema region on days 2, 5, and 8 after surgery. To determine lymphatic vessel positions using SEM analysis, we detected anti-lymphatic vessel endothelial hyaluronan receptor 1 (LYVE-1) immunoreactivity in serial sections and overlaid them during SEM observation. On days 2 and 5, spherical cells, probably myeloid cells, were attached and fused to the LYVE-1-positive lymphatic vessel walls. On day 8, spherical cells were converted to string-shaped cells, forming a new lymphatic vessel wall resembling an intraluminal pillar. Our results showed the newly formed lymphatic vessel wall extended into the lumen, suggesting intussusceptive lymphangiogenesis.

Lymphedema is a chronic and debilitating disease that affects up to 250 million patients worldwide. Recent advances in understanding its pathophysiology, along with improved diagnosis and microsurgical techniques, have enhanced our ability to cope with the challenging task of treating this disease. This review provides an overview of the disease from a surgeon’s point of view, including existing imaging modalities used for preoperative assessment, as well as surgical procedures used in its treatment. The advantages and drawbacks of various existing modalities used for the pre- or intraoperative assessment of lymphatic vessels are discussed. Lymphedema treatment has shifted from palliative debulking procedures (liposuction and direct excision) to those aimed at restoring lymphatic flow and countering the pathophysiology of the disease (lymphaticovenous anastomosis and vascularized lymph node transfer). A combination of both approaches can result in a synergistic benefit for patients and is discussed in this review. Despite recent advances, some controversies persist, and further studies are needed to better define surgical treatment algorithms.

The diagnosis and treatment of lymphoid neoplasms have undergone a continuously progressive positive change in the last three decades, with accelerated progress in the previous decade due to the advent of genomics in cancer diagnosis. Significantly, there has been an increasing emphasis on integrating molecular genetics with clinical, morphologic, immunophenotypic, and cytogenetic evaluation for diagnosis. As we think of moving forward with further advances in the genomics era, it is first helpful to understand our current state of knowledge and how we achieved it in the challenging and complex field of lymphoid neoplasms, which comprise very heterogeneous neoplastic diseases in children and adults, including clinically acute lymphoblastic leukemias (ALLs) arising from precursor lymphoid cells and clinically indolent and aggressive lymphomas arising from mature lymphoid cells. This work aims to provide an overview of the historical evolution and the current state of knowledge to anyone interested in the field of lymphoid neoplasms, including students, physicians, and researchers. Therefore, I discuss this complex topic in three review manuscripts, designated Parts 1–3. In Part 1, I explain the basis of the diagnostic classification of lymphoid neoplasms and its evolution up to the current fifth edition of the World Health Organization classification of hematolymphoid neoplasms, and the crucial importance of diagnostic tumor classifications in achieving and advancing patient care and precision medicine. In the second and third manuscripts, I discuss current diagnostic considerations for B-ALL and T-ALL (Part 2) and common indolent and aggressive mature leukemias/lymphomas (Part 3), including significant updates in the WHO 2022 classification, newly described entities, and concepts, including genetic predisposition to ALLs and lymphomas, and throughout emphasizing the essential integration of molecular genetics with clinical, morphologic (pathologic), immunophenotypic, and cytogenetic evaluation, as is required for precise diagnosis of the type of lymphoma/leukemia in any patient.

MYC deregulation, a cardinal event in Burkitt lymphoma (BL) pathogenesis, necessitates the elucidation of the molecular mechanisms governing MYC activation to devise innovative and effective therapeutic strategies. The t(8;14)(q24;q32) chromosomal translocation commonly observed in hematological malignancies results in MYC deregulation, endowing cancer cells with a competitive edge through heightened cell proliferation, cell cycle progression, apoptosis evasion, and metabolic reprogramming. Recent discoveries of recurrent MYC mutations in BL underscore the potential of precision medicine, employing tailored therapeutics to specifically inhibit MYC activity. However, the intricate genetic landscape of BL, featuring additional alterations, such as mutations in TP53, TCF3, and ID3, may necessitate a combinatorial approach targeting multiple oncogenic pathways for effective intervention. Despite significant strides in hematological malignancy treatment, a comprehensive understanding of the molecular mechanisms underpinning MYC’s oncogenic properties remains crucial for the potential development of highly potent and selective MYC-directed cancer therapies. This review offers an in-depth analysis of MYC translocation and its implications in Burkitt lymphoma, with a spotlight on cutting-edge advances in research and emerging therapeutic paradigms.

Proposed fundamental laws of biology and a model of health and disease underscore the importance of the lymphatic system. The lymphatics are responsible for two of the laws of biology and the fulcrum of health and disease balancing regeneration with degeneration through the immune system. It is responsible for protection from the environment and repair of senile and damaged tissue. Life is constantly bombarded by forces that increase entropy. Lymphatics provide negative entropy to maintain health. Lymphatics help maintain cellular homeostasis removing products of metabolism. Using these principles, the role of lymphatics is investigated in salt sensitivity hypertension, cardio-renal system, the new pillar of heart failure and kidney disease—Sodium-Glucose Transport Protein 2 (SGLT2) Inhibitors, and brain diseases. The realization of organ lymphatics in maintenance of health and disease opens the avenue to new therapeutics. This is the unrealized potential of lymphatic study.
