Prediction model of male reproductive function damage caused by CHOP chemotherapy regimen for non-Hodgkin's lymphoma.

The CHOP combined chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) is commonly used to treat non-Hodgkin Lymphoma (NHL). While these drugs are effective for cancer treatment, they may have side effects on the reproductive system that are poorly studied. This study used a mouse model to investigate the mechanisms of reproductive function impairment induced by the CHOP regimen and developed a predictive model for assessing reproductive damage with a non-invasive procedure. From 2022 to 2023, we statistically analyzed the changes of reproductive function of NHL patients before and after receiving CHOP regimen in the First Affiliated Hospital of Xiamen University. The NHL mouse model was established and divided into CHOP treatment group and control group. The weight of testis and epididymis, sperm quality and motility were compared between the two groups. Histopathological examination of testicular tissue was performed to determine pathological changes. ELISA was used to measure the expression of cytokines and cytokine pathways in serum, protein expression was analyzed by immunohistochemistry, and protein and mRNA levels of cytokines and pathways were evaluated by Western blotting and qPCR. Using stepwise regression method to select important factors, a prediction model of reproductive system damage was constructed. Fifty-two NHL patients included in the questionnaire showed significant reproductive system damage after CHOP regimen treatment. The weight of testis and epididymis, as well as the number and vitality of sperm in the mouse model treatment group were significantly lower than those in the control group. Serum LH, FSH, estradiol and progesterone levels decreased significantly, while inhibin B levels increased significantly. There was no significant change in testosterone or prolactin levels. Inflammatory markers such as CSF-1, IL-1, IL-6, TGF-β1 and GDNF increased significantly, while the level of SOD1 decreased significantly. Immunohistochemical staining analysis showed that CAMP, Caspase3, CSF-1, GDNF, IL-1, IL-6, PRKACB, TGF-β1 and TXNDC5 were all expressed in spermatocytes, and the expression of therapeutic histones was significantly higher than that of the control group. Western blot analysis further detected the protein expression, and QPCR detected the mRNA content. The results showed that the expression of histone and mRNA in the treatment group was significantly higher than that in the control group. Stepwise regression method determined that estradiol (E2) was the most important variable in the prediction model, and the AUC for predicting reproductive damage was 1. The CHOP regimen induces male reproductive toxicity, potentially mediated through alterations in hormone levels and increased expression of inflammatory cytokines and oxidative stress. Using E2 as the sole predictor in the model accurately predicts the extent of reproductive damage, offering a non-invasive method for detecting reproductive system damage.

Risk of second primary cancers in nodal non-Hodgkin lymphoma patients by primary lymph node location: a retrospective cohort population-based study.

Non-Hodgkin lymphoma (NHL) is a diverse group of blood cancers with increasing incidence and survival rates due to advancements in treatment and early detection. However, NHL survivors are at significant risk of developing second primary cancers, which can adversely impact their long-term survival. This retrospective population-based cohort study utilized data from the Surveillance, Epidemiology, and End Results database, covering 17 geographic areas in the United States from 2000 to 2021. The authors included patients diagnosed with nodal NHL as a first primary cancer and excluded those diagnosed at autopsy or via death certificate only. Standardized Incidence Ratios, Absolute Excess Risks, and Person-Years at Risk were calculated to evaluate the risk of developing SPCs according to the primary lymph node site and stratified by latency periods following the initial NHL diagnosis. The cohort included 54012 NHL patients. The authors' results showed that for most SPCs, the risk of development was different for different primary NHL lymph node locations. The highest risks were observed for thyroid cancer, acute myeloid leukemia, and Hodgkin lymphoma. Notably, the risk for thyroid cancer was highest in the first year post-diagnosis, while hematological malignancies such as acute myeloid leukemia and Hodgkin lymphoma showed elevated risks in the intermediate and late latency periods. NHL survivors are at an increased risk of developing SPCs, influenced by the primary lymph node site and latency period. These findings highlight the need for tailored surveillance strategies and preventive measures to mitigate the long-term risks of SPCs in NHL survivors. Further research is necessary to elucidate the underlying mechanisms and to develop targeted interventions for this high-risk population.

3D echocardiography and biomarkers for early diagnosis and prediction of chemotherapy induced right ventricular dysfunction in non-Hodgkin lymphoma patients

Abstract Background RCHOP (rituximab, cyclophosphamide, doxorubicin, oncovin, prednisone) use in non-Hodgkin's lymphoma (NHL) is limited by the risk of cardiotoxicity. Although the prognostic value of right ventricular (RV) function in mortality and morbidity has been well established, its involvement in chemotherapy-induced cardiotoxicity remains unclear. Aim To define new parameters able to detect early RV cardiotoxicity. Methods 51 patients (22 men, 61±14 years) with NHL scheduled for RCHOP, with three dimensional (3D) left ventricular (LV) ejection fraction (EF) >50%, were assessed at baseline, after 3rd and 6th cycle for right ventricular (RV) parameters: 3D EF, two dimensional (2D) global longitudinal strain (GLS) and free wall LS (FWLS), peak systolic annular velocity (S’), tricuspid annulus systolic excursion (TAPSE) and fractional area change (FAC). Biomarkers (troponin I, NT-pro-BNP) were measured. Cardiotoxicity was defined as LVEF reduction below 50% or preserved LVEF with LV LS decrease more than 15% from baseline. Results 15 (29%) of patients developed LV cardiotoxicity (group 1) while 36 did not fulfill this criteria (group 2). There was a significant reduction of RVEF, GLS, and FWLS, but not of RV S’, FAC, and TAPSE, starting with the 3rd cycle, with greater changes in group 1 vs. group 2 (see Table). RVEF reduction correlated with changes of FWLS, GLS, RV S’, and troponin (r=0.612, r=0.513, r=0.362, r=-0.358, respectively; all p<0.05). Reduction of FWLS after the 3rd cycle was the best independent predictor for RVEF decrease after the 6th cycle (R²=0.433, p<0.0001). FWLS decrease with more than 26% predicted cardiotoxicity after the 6th cycle (sensitivity of 81%; specificity of 78%). Conclusion 3D EF, 2D systolic deformation, and troponin I are able to detect early chemotherapy-induced right ventricular cardiotoxicity, and to predict further decline of RVEF in NHL patients. Thus, routine follow-up of RV function, along with the LV function, should be assessed during and after chemotherapy.RV parameters and troponin during RCHOP

Fifteen Years of Non-Hodgkin Lymphoma in an Indonesian National Referral Hospital: Epidemiologic Trends and Diagnostic Challenges.

The global burden of lymphoma is substantial because of the increase in its incidence in recent decades. However, disease characteristics vary across different geographical locations. Numerous immunohistochemistry markers and molecular studies are essential to determine lymphoma diagnosis and prognosis. This poses significant challenges in developing countries with limited health care resources. This large-scale study assesses the frequency of non-Hodgkin lymphoma (NHL) in Indonesia over the past 15 years, analyses its clinicopathologic features, and predicts future trends. This retrospective study collected lymphoma patients diagnosed at the Department of Anatomical Pathology Dr. Cipto Mangunkusumo National Central General Hospital, Indonesia, from 2009 until 2023. All lymphoma diagnoses were confirmed by using ancillary tools classified as an enhanced lymphoma panel according to a resource-stratified guideline. We analyzed the clinicopathologic features of each NHL type and further applied the Autoregressive Integrated Moving Average model to predict future incidence trends. The study consisted of 7,368 NHL patients. Among these, B-cell lymphomas accounted for 90.6%, with diffuse large B-cell lymphoma being the most prevalent subtype (68.8%), followed by follicular lymphoma (8.8%) and marginal zone lymphoma (5.8%). Extranodal natural killer/T-cell lymphoma, nasal type, is the most common T-cell lymphoma found (26.3%). All types of lymphoma were found to be more common in males (57.7%). Extranodal involvement, particularly in the tonsil and upper respiratory tract, was frequently observed. Projection analysis indicates a steady increase in lymphoma patients in the future. This study highlights the distribution and burden of NHL in Indonesia over 15 years. The overall epidemiologic pattern of NHL in this study aligns with the results observed in other Asian countries. The rising incidence of lymphoma requires improved health care infrastructure and prevention strategies.

Comprehensive analysis of constitutional mismatch repair deficiency-associated non-Hodgkin lymphomas in a global cohort.

Constitutional mismatch repair deficiency syndrome (CMMRD) is a rare childhood cancer predisposition syndrome associated with a broad spectrum of malignancies, including non-Hodgkin lymphomas (NHL). Most patients die due to cancer before the age of 20years. Limited data exist on CMMRD-associated lymphomas and their outcome. We conducted a retrospective study including all CMMRD-associated NHL patients registered before 2020 in the European and North American databases or reported by members of the European Intergroup for Childhood Non-Hodgkin Lymphoma (EICNHL). Events considered to define event-free survival included relapse/progression, second malignancy (SML), or death, whichever occurred first. The analysis included 74 patients, with 20 having multiple metachronous NHL. The median age at diagnosis was 9.4years. Previous malignancies were reported in 36% of the patients, café au lait spots in 96%, and consanguinity in 54%. The initial lymphoma subtypes were 53 T-cell lymphoblastic lymphomas (T-LBL), four B-lymphoblastic lymphomas, and 17 mature B-cell non-Hodgkin lymphoma (B-NHL). All patients were treated with curative intent, with current chemotherapy regimens adapted to their subtype. The median follow-up was 8.7years. After the first lymphoma, the 5-year event-free and overall survival rates were, respectively, 23.5% [95% confidence interval (CI): 14.9-35.1] and 61.5% [95% CI: 49.6-72.1]. The 5-year cumulative risk of progression/relapse, SML or death as a first event was 20.8%, 52.9%, and 2.7%. Standard treatments for sporadic NHL are effective in most CMMRD-associated NHL cases, but multiple malignancies, including lymphomas, impair prognosis. Future strategies should evaluate the potential of less genotoxic therapies, including immunotherapy, in preventing SMLs while maintaining effective control of NHL.

Real-World Insights into CAR T-Cell Therapy: Efficacy and Safety of Kymriah in B-ALL and NHL

Background: Chimeric Antigen Receptor (CAR) T-cell therapy has emerged as a revolutionary treatment for certain cancers, particularly B-cell malignancies. This study focused on the real-world outcomes of Kymriah (tisagenlecleucel), a CAR T-cell therapy targeting CD19, by analyzing data from the Cellular Immunotherapy Data Resource (CIDR). A total of 410 patients with relapsed or refractory B-cell Acute Lymphoblastic Leukemia (B-ALL) and Non-Hodgkin Lymphoma (NHL) were included. Methods: Data were collected from 73 treatment centers across the U.S. and Canada. Key outcomes measured included Cytokine Release Syndrome (CRS), Immune-effector Cell-Associated Neurotoxicity Syndrome (ICANS), overall response rate (ORR), duration of response (DOR), and survival rates. Statistical analyses were performed using descriptive statistics, Kaplan-Meier methods, and logistic regression. Results: CRS was observed in 54.3% of B-ALL patients, with severe cases in 16.1%. The complete remission rate in B-ALL patients was 85.5%, with a 12-month overall survival rate of 76.4%. In NHL patients, the overall response rate was 62.4%, with 38.2% achieving complete remission. Severe CRS and ICANS were less frequent in NHL patients. Conclusion: Kymriah demonstrated high efficacy in both B-ALL and NHL, with manageable side effects. However, ongoing monitoring is essential to optimize outcomes and reduce adverse events. This study provides valuable real-world data, contributing to the growing understanding of CAR T-cell therapy’s potential in clinical practice.

FCGR3A F158V alleles frequency differs in multiple myeloma patients from healthy population

ABSTRACT FCGR3A presents a single nucleotide polymorphism at location 158 (V/F), which affects its binding to the fragment crystallizable (Fc) of antibodies (Abs). FcγRIIIa-158 V allotype has the highest affinity and is associated with a better clinical response to IgG1 monoclonal Abs (mAb) treatment. We compared the allele frequency of FCGR3A-F158V polymorphism in cohorts of patients with B-cell lymphoproliferative disorders, including multiple myeloma (MM), monoclonal gammopathy of undetermined significance (MGUS), non-Hodgkin lymphoma (NHL), and B-cell chronic leukemia (B-CLL). FCGR3A-158F homozygous were enriched and tended to be in MM and MGUS patients, respectively; but neither in B-CLL nor in NHL patients. We identified a significantly lower concentration of CD8 T-cells and resting memory CD4 T-cells in MM patients bone marrow with the F/F genotype, associated with an increase in the macrophage percentage. In contrast, natural killer cells increased in V/V homozygous patients. This suggests a deregulation of the immune microenvironment in FCGR3A-F/F homozygous patients. However, we did not observe difference in response following treatment combining chemotherapy associated or not with daratumumab, an IgG1 mAb direct against CD38. Our findings suggest that FCGR3A F158V polymorphism can regulate the immune environment and affect the development of tumor plasma cells.

Evaluation of the incidence, predictors, risk assessment scores and outcomes of thromboembolism in a cohort of Egyptian NHL patients - Real World Experience

Non-Hodgkin’s Lymphoma (NHL) is the most common subtype of lymphoma. The incidence of venous thromboembolism (VTE) in aggressive NHL was estimated recently to be 11%. Several risk assessment scores and factors are available to help identify cancer patients at risk for developing VTE. Patients with a pathologically confirmed diagnosis of NHL were identified at the Oncology Center of Mansoura University. The study included 777 patients: 719 with DLBCL-NOS, 26 with Anaplastic-B-cell, and 32 with T-cell-rich-NHL. Data were retrospectively collected from electronic medical records, including clinical, radiological, and laboratory information related to VTE and NHL. The median age at NHL diagnosis was 53 years, (range: 18–98). There was a male predominance, 51.4% of the cases. At initial lymphoma diagnosis, VTE was identified in 46 (5.9%) patients, and 61 (7.9%) patients experienced VTE while undergoing chemotherapy. According to logistic regression analysis, a PS (performance status) ≥ 2, bulky lesions, and mediastinal masses were significant predictors of VTE at presentation, with P-values of 0.022, 0.002, and < 0.001, respectively. Meanwhile, NHL patients who developed VTE during chemotherapy had significantly poorer PS, higher absolute neutrophilic counts (ANC), neutrophil/lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and lactate dehydrogenase (LDH) levels than lymphoma patients without VTE, with P-values of 0.003, 0.034, 0.049, 0.01 and 0.007, respectively, as determined by multivariate analysis. The ROC curve identified the cut-off values of 4.875 × 109/L for ANC, 2.985 for NLR, 144.85 for PLR, and 417.5 U/L for LDH as potential markers for predicting VTE in NHL patients. Patients with a PS ≥ 2 and values exceeding these cut-offs for ANC, NLR, and PLR experienced significantly higher incidences of VTE than other groups, with P-values of 0.003, < 0.001, < 0.001, and < 0.001, respectively. At the end of the follow-up, the overall survival was significantly shortened by VTE occurring during chemotherapy, hypoalbuminemia, intermediate-high and high international prognostic index (IPI) scores (intermediate-high and high), responses other than CR and relapse, all with P-values < 0.05. ECOG PS and Inflammatory markers such as NLR, PLR, and neutrophilic count could serve as predictors of the development of thrombotic events in patients with NHL-DLBCL. Additionally, the occurrence of VTE during chemotherapy is an independent poor prognostic marker for overall survival (OS).

Clinical and Biomarker Characteristic of Lymphoma Patients in Hasan Sadikin Lymphoma Registry.

No specific data have been systematically collected regarding lymphoma patient characteristics, while non-Hodgkin lymphoma (NHL) is identified as the 7th most common cancer and Hodgkin lymphoma (HL) is the 28th. Inflammation plays an important role in the pathogenesis and progression of lymphoma. Malnutrition is an adverse prognostic factor in lymphoma. Systemic Inflammatory Index (SII), Prognostic Nutritional Index (PNI), and Advanced Lung Cancer Inflammation Index (ALI) were biomarkers depicting inflammation and nutritional status. This study aims to describe the clinical and biomarker characteristics of both HL and NHL patients. This descriptive study used a cross-sectional design, and data were collected from Hasan Sadikin Hospital lymphoma registry from January 2020 to November 2023. Demographic, staging, and histopathological data were extracted. Three biomarkers were evaluated. Survival curves were drawn using Kaplan-Meier curve analysis, and the log rank test was used for comparison of survival between early and advanced stage. A total of 271 patients were recruited as participants, and the majority (80.5%) had NHL, with diffuse large B-cell lymphoma (DLBCL) being the most common histopathological type (50.5%). Early disease was observed in two-thirds of patients, and low-risk International Prognostic Index (IPI) score was the most common prognostic score found (95%). SII was slightly higher in early compared to advanced stages. Treatment response was evaluated from 101 patients, and complete response was observed in 44.5%. Two-year overall survival (OS) was 93.1%, with median survival 22.7 (95% CI 21.9-23.5) months. In early stage, the median survival was slightly longer than in advanced stage [23.0 (95% CI 22.2-23.8) vs 21.6 (95% CI 19.3-23.8) months, P=0.09]. Hodgkin lymphoma and DLBCL had similar clinical and biomarker characteristics. There were slight differences between the three biomarkers SII, ALI, and PNI based on the disease stage. Almost all patients still survived at 2-year follow-up.

Effect of Coenzym Q10 on Doxorubicin-induced Cardiotoxicity in Non Hodgkin's Lymphoma Patients

BACKGROUND : Non-Hodgkin's Lymphoma is a primary malignancy in the Lymph Nodes and lymphoid tissue originating from B lymphocytes, T lymphocytes and Natural Killer (NK) cells. Therapy for Non-Hodgkin's Lymphoma chemotherapy can be given alone or combined with radioactive therapy. Doxorubicin is a chemotherapy drug used for lymphoma with side effects, one of which is cardiotoxic effects. AIMS : To prove that coenzyme Q10 can reduce the cardiotoxic effect of doxorubicin chemotherapy in non-Hodgkin's lymphoma patients METHOD : Intervention study with a randomized pre and post test double blind control group design with 34 NHL patients undergoing chemotherapy. The treatment group received additional therapy with coenzyme Q10 300mg/day for 12 weeks while the controls received placebo. The cardiotoxic effects examined were assessed based on the results of Electrocardiography and Echocardiography. RESULT : The treatment group with coenzyme Q10 supplementation after the 4th chemotherapy showed a decrease in echocardiography results in 3 patients (18%) and in the control group 17 patients (100%). There was a significant difference in the echocardiography results of the treatment and control groups (p=0.001). There were no drug side effects in both groups CONCLUSION : Coenzyme Q10 supplementation provides an improvement in the cardiotoxic effects of doxorubicin in non-Hodgkin's lymphoma patients, on echocardiography, but not on Electrocardiography.

The Experience of Timisoara Hematology Clinic on the Management of Aggressive Non-Hodgkin Lymphoma Patients

Objectives. One of the most prevalent types of malignant lymphoproliferative disorders is non-Hodgkin lymphoma (NHL), which has shown an increased frequency worldwide of roughly 168% since 1975, coinciding with a decline in the age at diagnosis. Despite a ten-year improvement in overall survival, NHL accounts for approximately 3% of all cancer-related deaths. Delays in diagnosis and the emergence of related comorbidities are caused by the diverse symptomatology and symptoms associated with NHL. Thus, the purpose of this study was to assess patients treated at Timisoara's Clinical Emergency Municipal Hospital who had been diagnosed with aggressive HNL. Material and methods. This cross-sectional study comprised 76 patients diagnosed with aggressive NHL between January 2020 and June 2023 who were admitted to Timisoara's Clinical Emergency Municipal Hospital. Biopsy along with histopathologic examination served as the basis for the diagnosis. As part of the first assessment, bone marrow biopsy and imaging studies (PET/CT) were carried out in addition to laboratory tests. The NHL was staged using the Ann Arbour classification. The present protocols were followed in the establishment of the treatment. PET/CT was used to assess the response to treatment. Results. In this study cohort 72% were stage 4 of NHL at the diagnosis, 16% were stage 3, 5% were stage 2, while only 2% were stage 1. B symptoms were present in 69% of cases. In patients with 4th stage of NHL, bone marrow represents the most frequent extranodal site. 57 patients finished minimum a complete chemotherapy line, from which 90% of the patients had complete (63%) or partial (24%) remission after first-line treatment. Conclusion. The importance of this study was to emphasize the heterogeneity of NHL and to evaluate the treatment response and survivance of aggressive NHL patients.

Cisplatin as a Viable and Secure Alternative to Carmustine in BEAM-Based Conditioning for Autologous Hematopoietic Stem Cell Transplantation in Patients with Lymphoma

BackgroundHigh-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) is a standard treatment for relapsed/refractory lymphoma patients. Yet, the widespread use of BEAM is hindered by carmustine accessibility. This study evaluates the efficacy and safety of PEAM (Cisplatin, Etoposide, Cytarabine, and Melphalan) versus BEAM in auto-HSCT for Hodgkin (HL) and non-Hodgkin lymphoma (NHL) patients. MethodsWe conducted a retrospective single-center study of adult lymphoma patients who received PEAM or BEAM pretransplant conditioning between January 2004 to December 2022, comparing efficacy and safety outcomes. ResultsAmong 143 patients (median age of 33 years, 58% males), 55 had HL, and 88 had NHL. The overall response rate (ORR) was 86.7% for PEAM and 72.3% for BEAM, and the relapse rate (RR) was lower for PEAM than BEAM (22.9% vs 45.6%). Median time to relapse (TTR) and overall survival (OS) were not reached for either group. PEAM exhibited a shorter time to both neutrophil (NE) and platelet (PE) engraftment compared to BEAM (10 vs 12 days), with a more tolerable gastrointestinal (GI) toxicity profile. ConclusionsBoth BEAM and PEAM showed similar outcomes, demonstrating comparable efficacy in terms of ORR, TTR, and OS for both HL and NHL patients. However, PEAM-conditioning was associated with a shorter time to engraftment and fewer GI adverse events.

Clinical Characteristics and Treatment Outcomes of Pediatric Patients with Non-Hodgkin Lymphoma: a Single-Center Experience From Southern Turkey

Purpose: Non‑Hodgkin lymphoma (NHL) accounts for 8‑10% of all childhood cancers. In this study, we aimed to describe the epidemiological and clinical characteristics and treatment outcomes of pediatric NHL patients treated at a tertiary center. Methods: The oncologic records of the patients diagnosed and followed up as NHL between 2013 and 2023 were reviewed retrospectively. Results: A total of 36 patients were enrolled in this study. The most common pathologic subtype was lymphoblastic lymphoma (LL) (n=21, 58.3%) followed by Burkitt lymphoma (BL) (n=10, 27.8%), diffuse large B-cell non-Hodgkin lymphoma (DLBCL) (11.1%, n=4), and anaplastic large cell lymphoma (ALCL) (2.8%, n=1). Overall survival (OS) and event-free survival (EFS) were significantly longer in patients without bone marrow (BM) involvement (p=0.001 and p=0.02, respectively). EFS was significantly longer in patients without central nervous system (CNS) involvement (p=0.038). OS and EFS did not differ significantly according to NHL subtypes (p&gt;0.05). There was no significant difference in OS according to age groups (p=0.7). Conclusion: The OS with NHL has significantly improved. With the development of effective treatment regimens based on various pathologic subtypes, the result of pediatric NHL has significantly improved in recent years. The survival rates have reached &gt;90%.

Clinical study of chemotherapy-related cognitive impairment in patients with non-Hodgkin lymphoma.

Chemotherapy for malignant tumors can cause brain changes and cognitive impairment, leading to chemotherapy-induced cognitive impairment (CICI). Current research on CICI has focused on breast cancer and Hodgkin's lymphoma. Whether patients with non-Hodgkin's lymphoma (NHL) undergoing chemotherapy have cognitive impairment has not been fully investigated. To investigate whether NHL patients undergoing chemotherapy had cognitive impairments. The study included 100 NHL patients who were required to complete a comprehensive psychological scale including the Brief Psychiatric Examination Scale (MMSE) at two time points: before chemotherapy and within 2 wk of two chemotherapy courses. A language proficiency test (VFT), Symbol Number Pattern Test (SDMT), Clock Drawing Test (CDT), Abbreviated Daily Cognition Scale (ECog-12), Prospective and Retrospective Memory Questionnaire, and Karnofsky Performance Status were used to assess cognitive changes before and after chemotherapy. The VFT scores for before treatment (BT) and after treatment (AT) groups were 45.20 ± 15.62, and 42.30 ± 17.53, respectively (t -2.16, P < 0.05). The CDT scores were 8 (3.5-9.25) for BT and 7 (2.5-9) for AT groups (Z -2.1, P < 0.05). Retrospective memory scores were 13.5 (9-17) for BT and 15 (13-18) for AT (Z -3.7, P < 0.01). The prospective memory scores were 12.63 ± 3.61 for BT and 14.43 ± 4.32 for AT groups (t -4.97, P < 0.01). The ECog-12 scores were 1.71 (1.25-2.08) for BT and 1.79 (1.42-2.08) for AT groups (Z -2.84, P < 0.01). The SDMT and MMSE values did not show a significant difference between BT and AT groups. Compared to the AT group, the BT group showed impaired language, memory, and subjective cognition, but objective cognition and execution were not significantly affected.

Optimization and characterization of Rituximab targeted multidrug loaded cyclodextrin nanoparticles against Non-Hodgkin Lymphoma

Currently, Non-Hodgkin Lymphoma (NHL) constitutes 85–90 % of all lymphomas. Clinical treatment of NHL is based on the “4-drug regimen” known as CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone). Rituximab (RTX) is added to increase the effectiveness and selectivity of the treatment and is the first-line standard treatment for NHL patients. However, success is often prevented by the development of drug resistance. In this study, it was aimed to overcome drug resistance by using two novel tumor-targeted derivatives: guanidine-amphiphilic cyclodextrin (ACD) and guanidine-cyclodextrin polymer (PCD) nanoparticles (NP). These constructs display promise in overcoming drug resistance and enhancing the effectiveness of R-CHOP treatment while potentially eliminating the need for corticosteroid. NP were found to be smaller than 200 nm by dynamic light scattering (DLS). Hemolytic activity and cytotoxicity data on L929 cells demonstrated the safety of the newly synthesized CD derivatives. Additional in vitro characterization studies, including surface charge, physical stability, drug loading capacity, drug release profile, and imaging, as well as conventional and 3D cell culture studies were carried out. Compared to drug solutions, the viability of Daudi human lymphoma cells was statistically significantly decreased in both drug-loaded ACD and PCD NP formulations (p < 0.05). Additionally, RTX-conjugated and drug-loaded ACD NPs exhibited the lowest cell viability due to RTX dependent cytotoxicity.

Non-Hodgkin lymphoma presenting with spinal cord compression: A population-based analysis of the NHL-BFM study group.

Spinal cord compression is a rare presentation of non-Hodgkin lymphoma (NHL) in children. We aimed to describe the prevalence, histological subtypes, clinical presentation, therapy, and outcome of those children in a population-based cohort. The chemotherapy regimen remained comparable over time. We retrospectively identified all children and adolescents with paresis as initial manifestations of the NHL between January 1990 and December 2020 from the NHL-BFM database. Characteristics, therapy, and outcome data were gathered from the database and patient files. Fifty-seven of 4779 children (1.2%) presented with initial paresis due to spinal cord compression. The median age was 10.3 years (range, 3.1-18.0 years), and 33% were female. Initial symptoms were paresis/weakness (n=50, 88%), back pain (n=33, 58%), paresthesia (n=23, 40%), and bladder dysfunction and/or constipation (n=22, 39%), persisting for a median of 14 days before diagnosis. Subtype distribution was mature B-NHL (n=41, 72%), precursor B-lymphoblastic lymphoma (LBL) (n=12, 21%), anaplastic large cell lymphoma (ALCL) (n=3, 5%), and T-LBL (n=1, 2%). Initial emergency therapy included surgery (70%) and/or chemotherapy/steroids (63%). Five-year event-free survival and overall survival (80%±5% and 82%±5%, respectively) were comparable with all other NHL patients. Neurological symptoms persisted in approximately one-third of surviving patients at the last follow-up. 1.2% of pediatric NHL patients presented with paresis from spinal cord compression mainly due to B-cell lymphomas. Neurological sequelae were observed in one-third of surviving patients.

Immunohistochemical study of non-Hodgkin lymphoma patients in Basrah (Single center experience)

Background. Non-Hodgkin lymphoma (NHL) represents a diverse group of lymphoid tissue cancers, predominantly arising from B-cells, T-cells, or natural killer cells. The accurate diagnosis of NHL subtypes is crucial, given their varying clinical behavior and treatment responses. This study focuses on the application of immunohistochemistry (IHC) in diagnosing and classifying NHL, comparing its efficacy to traditional hematoxylin and eosin (H&amp;E) staining methods. Methods. Conducted at Al-Sadr Teaching Hospital, Basrah, this cross-sectional study involved 48 newly diagnosed NHL cases in 2015. Patients were initially examined using H&amp;E-stained sections from lymph nodes and extranodal tissue biopsies. IHC staining, employing a range of primary antibodies, was then used to confirm diagnoses and subtype NHL cases. Results. The study revealed a predominance of diffuse large B-cell lymphoma (DLBCL) at 50%. Other subtypes that were identified included mantle cell lymphoma, Burkitt lymphoma, lymphoblastic lymphoma, MALToma, peripheral T-cell lymphoma, and follicular lymphoma. The IHC method proved critical in identifying specific NHL subtypes, which were not detectable by H&amp;E staining alone, such as mantle cell lymphomas and peripheral T-cell lymphomas. The study highlighted discrepancies with regional studies, emphasizing variations due to sample size and regional factors. Conclusion. Immunohistochemical staining is an indispensable tool for accurately diagnosing and classifying NHL, complementing H&amp;E staining. This study underscores the need for a comprehensive diagnostic approach, including a panel of antibodies, to optimize the diagnostic process and ensure accurate treatment planning.

Elevated serum cathepsin S is associated with HDL3a and HDL3b subclasses in non-Hodgkin lymphoma patients

Background: Recent findings point to the key role of cathepsin S (CTSS) in the survival of malignant cells, as well as the significance of the anti-apoptotic properties of high-density lipoprotein (HDL) that contribute to enhanced cell survival. The purpose of this study is to analyze CTSS as a potential biomarker in lymphoma. Also, in order to better understand the role of CTSS in the origin and development of lymphoma, its association with cystatin C (Cys C), lipids, and inflammatory markers was analyzed. Methods: The study included 90 subjects: 11 Hodgkin (HL) and 44 B-cell non-Hodgkin lymphoma (NHL) patients, and 35 healthy subjects. CTSS was determined using the Invitrogen ELISA kit (Thermo Fisher Scientific, Inc., Waltham, MA, USA). Results: The level of CTSS was significantly higher in NHL patients than in control subjects: 12.20 (9.75-14.57) vs 9.97 (8.44-10.99), P&lt;0.001. In NHL patients, there was a positive correlation between CTSS and the proportions of HDL3a, HDL3b, and the sum of the HDL3 subclasses (r=0.506, P&lt;0.001; r=0.411, P=0.006, r=0.335, P=0.026, respectively). In addition, the area under the receiver operating characteristic curve (AUC curve) of CTSS was 0.766 (CI: 0.655-0.856). Conclusions CTSS is significantly elevated in patients with NHL and has the potential to be a new diagnostic biomarker. Moreover, demonstrating a correlation between CTSS levels and the proportion of anti-apoptotic HDL3a and HDL3b subclasses improves understanding of NHL, as well as contributes to the development of new therapeutic strategies for this cancer.

Cost burden of chemotherapy for Indonesian healthcare insurance and social security/Jaminan Kesehatan Nasional (JKN) patients with non-Hodgkin lymphoma.

Cancer is among the leading causes of death globally, posing a significant economic burden on the healthcare sector. Among other types of cancer in Indonesia, non-Hodgkin lymphoma (NHL) ranks fifth in terms of prevalence. Chemotherapy for NHL patients is funded by a national health insurance scheme through the National Healthcare Insurance and Social Security/Jaminan Kesehatan Nasional (JKN). This study aimed to analyze cost burden of chemotherapy for JKN patients with NHL. A retrospective cross-sectional observational study was conducted among NHL patients receiving chemotherapy at a hospital in East Java, Indonesia in 2021. Data were collected from medical record documents and a total of 44 patient visits were recorded in this study. The result showed that patient visits were dominated by females (55%), a significant proportion were aged 31 to 40 years (32%), and the majority were JKN participants in the Contribution Assistance Recipients/Penerima Bantuan Iuran (PBI) category (64%). The most chemotherapy regimen given was R-CHOP (68%) and the mean total cost for NHL patients was Indonesian Rupiah (IDR) 5,178,146. The highest mean cost burden was on chemotherapy drugs with a value of IDR 6,333,315. Based on the regimen, the highest cost burden was R-CHOP-Bleo with a mean cost of IDR 8,764,091. Based on the results, the highest cost burden for chemotherapy among JKN patients with NHL in Indonesia was attributed to R-CHOP-Bleo regimen with a mean of IDR 8,764,091.

Effects and outcomes of tumor lysis syndrome in patients admitted with Hodgkin and non-Hodgkin lymphoma: A National Inpatient Sample study (2019-2020).

e19032 Background: Tumor Lysis Syndrome (TLS) is a life-threatening oncologic emergency. The newer advancement in therapeutic approaches in oncology has widened the range of malignancies associated with TLS. A lot of literature on the incidence of TLS in various solid malignancies exists. However, the effects of TLS on hematological malignancies, especially Hodgkin’s Lymphoma (HL) and Non-Hodgkin’s Lymphoma (NHL) have rarely been analyzed. Our study aims to identify the impact of TLS in patients hospitalized with HL and NHL and draw a comparison between HL and NHL. Methods: We analyzed the National Inpatient Sample database from 2019 - 2020 to identify patients &gt; 18 years old with a primary diagnosis of HL and NHL. We compared the TLS prevalence and all-cause in-hospital mortality, length of hospital stay (LOS), and total costs in patients admitted with HL and compared it with NHL. Categorical variables were compared using the chi-square test, and the t-test compared continuous variables. Multivariable regression analyses were performed adjusting for demographics, hospital-level characteristics, and relevant comorbidities. Results: Among 24,550 Hodgkin’s Lymphoma (HL) hospitalizations and 108,060 Non-Hodgkin’s Lymphoma (NHL) hospitalizations, TLS was diagnosed in 0.69% of HL patients and 0.89% of NHL patients. In-hospital mortality was significantly higher in both HL (44.1%) and NHL (28.3%) patients with TLS compared to those without TLS (HL: 4.5%, NHL: 5.1%). Multivariate regression analysis revealed that TLS presence increased the chance of mortality among both HL (OR 17.9) and NHL (OR 7.3) patients. TLS also significantly impacted secondary outcomes including Acute Kidney Injury (AKI) and Hyperkalemia in both HL and NHL patients. No statistically significant differences were found in the odds of cardiac arrhythmias between HL and NHL patients with TLS (Table). TLS was associated with longer Length of Stay and higher total hospital costs in both HL and NHL patients compared to those without TLS. Conclusions: TLS is significantly associated with increased mortality in patients with HL and NHL, more in HL compared to NHL. In patients with HL, and NHL, TLS is an independent risk factor for in-patient mortality, the longer LOS, and the total cost, thereby incurring an increased burden on healthcare resources. Our study aims to highlight the need for greater vigilance in this vulnerable group when TLS occurs. [Table: see text]
