T-cell acute lymphoblastic leukemia (T-ALL) is a rare hematologic malignancy with a unique set of clinical challenges when it occurs in adults. This case report presents the complex management of a 32-year-old male with T-ALL who developed symptomatic hyperleukocytosis and tumor lysis syndrome. Upon presentation, the patient exhibited a constellation of critical clinical and laboratory findings, including leukocytosis, anemia, thrombocytopenia, hyperkalemia, high-anion gap metabolic acidosis, and acute kidney injury...

Up to 50% of patients with high-risk myeloid malignancies die of relapse after allogeneic stem cell transplantation. Current sequential conditioning regimens like the FLAMSA protocol combine intensive induction therapy with TBI or alkylators. Venetoclax has synergistic effects to chemotherapy. In a retrospective survey among German transplant centers, we identified 61 patients with myeloid malignancies that had received FLAMSA-based sequential conditioning with venetoclax between 2018 and 2022 as an individualized treatment approach...

OBJECTIVE: To improve the understanding of aggressive NK-cell leukemia (ANKL) and summarize the progress of its diagnosis and treatment. METHODS: We retrospectively analyzed a case of a patient who was initially diagnosed with T-cell lymphoma (non-specific type) and later transformed into ANKL through examinations such as bone marrow smear, flow cytometry, Q-mNGS, and pathology. We described the patient's diagnostic and treatment journey and conducted a literature review...

Tumor lysis syndrome (TLS) remains a debilitating cause of hospitalization and death in patients with cancer and is a significant challenge for healthcare providers despite advancements in its management. This umbrella review analyzed the results of meta-analyses on the use of rasburicase in the treatment of patients with cancer.

Amidst the complexities of managing primary brain tumors, this report underscores the significance of thorough morphopathological examination, while considering patient demographics and tumor localization in assessing the nature of the neoplasm...

Chronic myelomonocytic leukemia (CMML) is a hematologic malignancy affecting the bone marrow and resulting in peripheral blood monocytosis. Kidney and urinary tract involvement is common and can present dramatically with life-threatening consequences. Kidney involvement can be the result of direct or indirect mechanisms, including prerenal azotemia, glomerular disease, tubulointerstitial involvement, and renovascular disorders. Urinary tract involvement, electrolyte and acid-base disorders, as well as nephrotoxicity from treatment of the disorder can also occur...

OBJECTIVE: The purpose of our study is to investigate the laboratory and clinical features of tumor lysis syndrome (TLS) and acute kidney injury (AKI) in childhood non-Hodgkin lymphomas (NHL) and to reveal their impact on long term kidney function in survivors. METHODS: Our single-center retrospective study included 107 patients (0-18 years old) with NHL who were admitted and treated at our hospital between 1998 and 2020. The relationship between TLS and age, gender, histopathological subgroup, tumor stage, lactate dehydrogenase (LDH) level at presentation, bone marrow and kidney involvement were assessed...

BACKGROUND: Hepatic cancer is a common cancer in clinical practice. Current drug therapies for this condition include targeted therapy, chemotherapy, and immunotherapy. Tumor lysis syndrome (TLS) is the most serious complication of oncology treatment. According to the literature, several cases reported TLS occurred with targeted therapies for hepatic cancer. METHODS: Reporting odds ratio and information component were used to measure the disproportionate signals for TLS associated with targeted therapies, using data from the FDA's Adverse Event Reporting System (FAERS)...

Neuroblastoma is a common pediatric tumor arising from the post-ganglionic sympathetic nervous system and is associated with hypertension in 25% of cases. We describe an unusual case of labile, multi-drug resistant hypertension associated with chemotherapy administration for neuroblastoma and provide potential management strategies in this scenario. We report the case of a 4-year-old female with a history of headaches who presented with hypertensive emergency and evidence of end-organ damage, including posterior reversible encephalopathy syndrome, acute cerebral infarct, concentric left ventricular hypertrophy, and growth failure secondary to a large, abdominal catecholamine-secreting neuroblastoma, which compressed the kidney vasculature and inferior vena cava...

Venetoclax is a first-in-class B-cell lymphoma-2 (BCL-2) inhibitor approved as continuous monotherapy and in combination with rituximab as fixed-treatment duration for relapsed and refractory chronic lymphocytic leukemia (R/R CLL). DEVOTE was a 24-week, multicenter observational study (NCT03310190) evaluating the safety, healthcare resource utilization (HCRU) and health-related quality of life (HRQoL) of patients initiating venetoclax for R/R CLL in Canada. Overall, 89 patients received 1 dose of venetoclax; 80% had prior exposure (42% resistant) to ibrutinib...

Coronavirus disease 2019 (COVID-19) can become lethal in patients with hematological malignancies; however, several cases of tumor regression after COVID-19 have been described, and the precise mechanism behind this paradoxical effect is unknown. Herein, we describe a case of Tumor lysis syndrome (TLS) followed by tumor regression after COVID-19. A 72-year-old woman with untreated chronic lymphocytic leukemia was admitted to our hospital with SARS-CoV-2 antigen-positive pneumonia. On admission, her anti-SARS-CoV-2 spike antibody was negative despite receiving two prior vaccinations...

Bispecific antibodies (BsAbs) are monoclonal antibodies that simultaneously bind to a specific antigen on tumors and CD3 on T cells, leading to T cell activation and subsequent tumor cell lysis. Several CD20 × CD3 BsAbs are being developed for B-cell lymphomas. Furthermore, multiple clinical trials to evaluate BsAbs for the treatment of multiple myeloma, with targets including BCMA, GPRC5D and FcRH5, are ongoing. Emerging evidence suggests promising efficacy in heavily pretreated patients with relapsed or refractory lymphoid malignancies, showing an overall response rate of 50-60%, with complete response rates of 30-40% for relapsed or refractory large B-cell lymphoma and 60-70% for relapsed or refractory multiple myeloma...

Tumor lysis syndrome (TLS) is a potentially fatal oncological emergency that typically develops during the treatment of rapidly proliferating malignancies. It is infrequently reported in solid tumors, such as pulmonary adenocarcinoma. A 59-year-old male patient with shortness of breath presented with a 3.3 cm × 3.0 cm mass in the right upper lobe, along with massive right-sided pleural effusion. A percutaneous needle biopsy was performed, and a diagnosis of pulmonary adenocarcinoma with an epidermal growth factor receptor ( EGFR ) mutation was made...

OBJECTIVE: Extramedullary relapse (EMR) is rare in acute promyelocytic leukemia (APL) and, there is a lack of information on its management. Current practices for EMR in APL are always to adopt strategies from other subtypes of Acute lymphoblastic leukemia (ALL) and Acute myeloid leukemia (AML). Gilteritinib, a highly selective FLT3 inhibitor, has demonstrated a remarkable effect on EMR in FLT3-mutant AML. Therefore, it is worthwhile exploring if FLT3 mutation can be a therapeutic target and assessing the efficacy of Gilteritinib on FLT3-mutant EMR in APL...

The current chemotherapy treatments have led to an improvement in survival rates for pediatric Burkitt's lymphoma (BL). Survival in children with high-grade, mature B-cell non-Hodgkin's lymphoma (B-NHL) has been prolonged by six rituximab doses combined with chemotherapy, whereas the efficacy of four doses has not been reported. This study aimed to explore optimal therapeutic strategies-the number of doses of rituximab based on different risk groups-and also aim to investigate the clinical characteristics of Chinese pediatric BL...

BACKGROUND: After C-X-C motif chemokine receptor 4 (CXCR4)-directed radioligand therapy (RLT), lymphoma patients are scheduled for conditioning therapy (CON) followed by hematopoietic stem cell transplantation (HSCT). We aimed to determine whether CXCR4-RLT can achieve bone marrow ablation and direct antilymphoma activity independent from CON/HSCT and also evaluated the safety profile of this theranostic approach in an acute setting. PATIENTS AND METHODS: After CXCR4-directed 68Ga-pentixafor PET/CT, 21 heavily pretreated patients with hematological malignancies underwent CXCR4-directed RLT using 90Y-pentixather...

Autologous CAR-T cell therapy (CAR-T) has improved outcomes for patients with B-cell malignancies. It is associated with the well-described canonical toxicities cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), which may be abrogated by corticosteroids and the anti-IL6 receptor antagonist tocilizumab. Practitioners and researchers should be aware of additional toxicities. Here we review current understanding and management of hematologic toxicities after CAR-T, including cytopenias, coagulopathies, bleeding and clotting events, hemophagocytic-lymphohistiocytosis, and tumor lysis syndrome...
