Acute lymphoblastic leukemia (ALL) represents only 20 % of adult acute leukemias, while Lymphoblastic lymphoma is even rarer, accounting for 2 % of adult non-Hodgkin lymphomas. T-acute lymphoblastic leukemia (T-ALL) and T-lymphoblastic lymphoma (T-LBL) are neoplasms characterized by the presence of immature T-cell precursors or lymphoblasts. Relapsed T-ALL or LBL is associated with a very poor prognosis, necessitating the exploration of novel therapeutic approaches. This case report describes the use of Venetoclax in combination with Cladribine, Idarubicin, and Cytarabine (CLIA) as salvage therapy for relapsed T-ALL/T-LBL. The treatment regimen resulted in remission and negative minimal residual disease. However, it was accompanied by delayed count recovery, febrile neutropenia, and Central Line-Associated Bloodstream Infection. The management of central nervous system involvement was challenging due to low platelet counts requiring transfusion support. The findings highlight the need for further investigation into the efficacy and optimal therapeutic regimen for relapsed T-ALL/T-LBL. Additionally, the case emphasizes the importance of early salvage therapy and potentially consolidative hematopoietic stem cell transplantation for improved survival outcomes in relapsed T-ALL/T-LBL patients.

Multiple myeloma (MM) is a rare hematologic malignancy with a 5-year survival rate of 52 %. For transplant-eligible MM patients, high-dose chemotherapy followed by autologous stem cell transplant (ASCT) is recommended. Given the complexities of the ASCT procedure, understanding patient-specific factors and their impact on treatment decisions is essential.
Our study examines patient characteristics and patterns of health resource utilization associated with ASCT receipt in patients with MM.
This retrospective study used the Merative™ MarketScan® database from 2017 to 2019 to analyze working-aged adults (18–65 years) with MM. We categorized 643 ASCT recipients by demographic characteristics (age, sex, region, employment status, year of ASCT procedure) and clinical factors (Charlson Comorbidity Index score). We assessed health resource utilization, focusing on ASCT-related costs, including total payments and hospitalization duration. Descriptive statistics were calculated for all variables, with means, medians, standard deviations for continuous variables, and frequencies for categorical variables. Pearson correlation assessed the relationship between total payment and hospitalization duration.
Over 80 % of patients were over 50, highlighting the need for age-specific clinical strategies. Most patients had CCI scores of 2–4, indicating a moderate comorbidity burden. The mean hospitalization duration was 21.71 days, with average ASCT costs totaling $166,235.99. The correlation coefficient of 0.21 indicated that total payments also increase as the number of hospitalization days increases.
These findings highlight the need for tailored care approaches and resource allocation in ASCT, informing future research and clinical decision-making.

Hairy cell leukemia (HCL) is a rare, indolent B-cell lymphoma that is highly responsive to the purine analog cladribine. A defining feature of classical HCL is the presence of the BRAF V600E mutation, which is almost universally present. The transformation of HCL to an aggressive large B-cell lymphoma is extremely rare. Here, we report a case of intercurrent presentation of worsening classical HCL with a rapidly evolving BRAF V600E-negative aggressive large B-cell lymphoma and associated hemophagocytic lymphohistiocytosis (HLH). The contiguous presentation of these three entities posed significant diagnostic and therapeutic challenges. Despite treatment with cladribine, the patient’s condition deteriorated, leading to a palliative focus. This case underscores the challenges of managing multiple intercurrent hematologic malignancies manifesting with overlapping symptoms and sites of organ involvement but non-overlapping treatments. The presence of HLH as a complication in patients with malignancy further complicates the clinical picture and requires early recognition and prompt intervention. Further research is needed to better understand the pathophysiological links between HCL, large cell transformation, and HLH. Additionally, registry or other cross-sectional studies with larger numbers of HCL patients could clarify the exact frequency of these rare but fatal complications.

Background
AL amyloidosis is a systemic protein misfolding disorder characterized by organ deposition of monoclonal immunoglobulin fragments, with insidious onset and progressive course. The plasma cell clone in the bone marrow is relatively small and typically does not impair hematopoiesis, in contrast to multiple myeloma. Herein we present a novel observation of increased thrombocyte, leukocyte and erythrocyte counts in a subset of AL amyloidosis patients.
Material and Methods
We performed a retrospective analysis of medical records of all consecutive patients diagnosed with AL amyloidosis at the Medical University of Warsaw in years 2001–2022, which included clinical, pathological and laboratory data, as well as treatment protocols and outcomes.
Results
Twenty-three patients out of 124 (18.4 %) included had elevated blood counts: 17 (13.6 %) had leukocytosis with neutrophilia, 7 (5.6 %) had thrombocytosis, whereas 2 (1.6 %) had erythrocytosis. In comparison to the remaining AL population this subgroup was characterized by younger age (median 57 vs 62 years, p = 0.018), higher frequency of hepatomegaly (42.9 % vs.14.7 %, p = 0.004), higher median alkaline phosphatase concentration (129 U/L vs 93 U/L, p = 0.006) and more frequent hepatic amyloidosis (34.8 % vs 10.3 %, p = 0.003). None of the patients had definite features of a myeloproliferative neoplasm, although genetic testing was available in 5 out of 9 cases with thrombocytosis or erythrocytosis. There were no significant differences in terms of survival between patients with elevated cell counts and non-polycythemic patients (median overall survival 2.9 vs 6.6 years, p = 0.51, median event-free survival 0.7 vs 1.8 years, p = 0.29, respectively).
Conclusions
Elevated peripheral blood counts in a subset of patients with AL amyloidosis constitute a rare but significant phenomenon and appear to be associated with frequent hepatic involvement. We hypothesize that cytokine deregulation and hyposplenism may belong to its pathomechanisms.

Background
Mature B-cell non-Hodgkin lymphoma (B-NHL) is a prevalent pediatric malignancy with significant treatment advancements. This study retrospectively analyzes clinical characteristics, treatment outcomes, and survival rates of children and adolescents diagnosed with B-NHL at Al-Hasan Al-Mojtaba Hospital between January 2014 and December 2024. A comparative analysis was performed between the LMB96 and R-CHOP regimens.
Methods
Patients with confirmed diagnoses of Large B-cell lymphoma or Burkitt’s lymphoma, based on WHO classification criteria, were included. Staging was conducted using the St. Jude system, and risk classification followed the FAB/LMB criteria. Treatment involved a modified LMB96 regimen, later replaced by R-CHOP in the last two years of the study. Event-free survival (EFS) was analyzed using Kaplan-Meier survival curves, with stratifications by staging, risk group, and gender.
Results
A total of 66 patients were included (median age: 5.8 years; 69.7 % male). Burkitt’s lymphoma was the predominant histology (86.3 %). The abdomen was the most common primary site (84.8 %). The majority of patients (72.7 %) presented with advanced-stage disease (Stages III and IV). Risk group classification identified 62.1 % of patients in Group B and 28.8 % in Group C. Kaplan-Meier survival analysis revealed Group A had the most favorable prognosis (EFS ∼100 %), followed by Group B (∼75 %), and Group C (∼50 %). Disease stage significantly influenced survival (p = 0.021), with Stage IV patients demonstrating the poorest outcomes. While female patients exhibited higher EFS than males, the difference was not statistically significant (p = 0.27). By the end of follow-up, 28.8 % of patients had experienced a fatal outcome.
Conclusion
Advanced-stage B-NHL remains prevalent, with significant survival differences based on staging and risk classification. The transition from LMB96 to R-CHOP warrants further evaluation to optimize pediatric treatment strategies. Larger studies are needed to validate observed gender-based survival trends.

Myeloid sarcomas (MS) are rare extramedullary manifestations of myeloid progenitor cells occurring with or without acute myeloid leukemia. Peritoneal MS is exceptionally uncommon, with no established treatment guidelines, but treatment has historically consisted of cytotoxic chemotherapy. We present the case of a 78-year-old female with 60% CD34+, HLA-DR+, and CD33+ myeloblasts in ascitic fluid, while bone marrow biopsy demonstrated only molecular evidence of the leukemic clone with FLT3-ITD, ASXL1, and TET2 mutations. Findings were consistent with primary peritoneal myeloid sarcoma. Due to chemotherapy ineligibility, the patient was treated with decitabine and venetoclax. After nine cycles, she demonstrated a complete radiographic response. To our knowledge, this is the first case report of a patient with primary peritoneal MS treated with a combination of a hypomethylating agent and venetoclax.

Presented here is the case of a 68-year-old woman with blastic plasmacytoid dendritic cell neoplasm (BPDCN) treated with tagraxofusp (TAG) maintenance therapy post-allogeneic hematopoietic stem cell transplantation (allo-HCT). Prior to allo-HCT, the patient was treated with hydroxyurea and mini-CVD (cyclophosphamide, vincristine, and dexamethasone alternating with methotrexate (Methotrexate) and cytarabine) + venetoclax + TAG for 5 cycles, which induced morphologic complete remission with minimal residual disease. After allo-HCT, the patient had persistent cytogenic abnormalities 45,XX,der(7)add(7)(p13)del(7)(q11.2q22)add(7)(q32),add(12)(p13),-15,del(16)(q23),-17,+22,+2mar[1]/46,XX[19], and was then treated with TAG maintenance therapy at 9 mg/kg on a 28-day cycle for 16 cycles. At mid-treatment (cycle 6 of 16 cycles of TAG) and prior to TAG discontinuation (due to travel burden), the patient was negative for minimal residual disease and was in complete remission. There was no high-grade toxicity or capillary leak syndrome. The patient remains in complete remission as of present day (>17 months CR). This is the first case study illustrating the feasibility of long-term TAG maintenance post-allo-HCT to control BPDCN.

Prior to allo-HCT, the patient was treated with hydroxyurea and mini-CVD (cyclophosphamide, vincristine, and dexamethasone alternating with methotrexate (Methotrexate) and cytarabine) + venetoclax + TAG for 5 cycles, which induced morphologic complete remission with minimal residual disease.

At mid-treatment (cycle 6 of 16 cycles of TAG) and prior to TAG discontinuation (due to travel burden), the patient was negative for minimal residual disease and was in complete remission. There was no high-grade toxicity or capillary leak syndrome. The patient remains in complete remission as of present day (>17 months CR). This is the first case study illustrating the feasibility of long-term TAG maintenance post-allo-HCT to control BPDCN.</div></div>","PeriodicalId":38435,"journal":{"name":"Leukemia Research Reports","volume":"24 ","pages":"Article 100518"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144306788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
