We report on the emergence and clinical relevance of an unusual BCR-ABL1 kinase domain mutational status in a 2-year-old female with p210-BCR-ABL Philadelphia chromosome-positive acute lymphoblastic leukaemia. We detected three BCR-ABL1 clones determined by the presence of the E255V, D276G and F317L mutations. We point out the usefulness of searching for mutated populations that survive tyrosine-kinase inhibitor therapy and the role of their clonal selection over time in relation to therapeutic intervention.

Early T-cell Precursor Acute Lymphoblastic Leukemia (ETP-ALL) is an immature subtype of T-cell acute lymphoblastic leukemia (T-ALL) commonly show deregulation of the LMO2-LYL1 stem cell transcription factors, activating mutations of cytokine receptor signaling, and poor early response to intensive chemotherapy. Previously, studies of the Lmo2 transgenic mouse model of ETP-ALL identified a population of stem-like T-cell progenitors with long-term self-renewal capacity and intrinsic chemotherapy resistance linked to cellular quiescence. Here, analyses of Lmo2 transgenic mice, patient-derived xenografts, and single-cell RNA-sequencing data from primary ETP-ALL identified a rare subpopulation of leukemic stem cells expressing high levels of the cytokine receptor FLT3.

Purpose: Patients with adolescent and young adult (AYA) cancer are recognized as a vulnerable subpopulation in high-income countries (HICs). Although survival gaps between HIC and low- and middle-income country (LMIC) children with cancer are well described, LMIC AYAs have been neglected. We conducted a systematic review to describe cancer outcomes among LMIC AYAs.

Background: The treatment of relapsed/refractory T cell acute lymphoblastic leukemia (R/R T-ALL) is a significant challenge in hematologic oncology, and no standard salvage treatment plan exists. Both Chinese and international clinical guidelines recommend combination chemotherapy including venetoclax.
Methods: Efficacy and safety of venetoclax, azacitidine, homoharringtonine, cytarabine, and aclarubicin (VA-HAA) combination therapy were retrospectively analyzed in 3 patients with R/R T-ALL at the Department of Hematology, 920th Hospital of the Joint Logistics Support Force, Chinese People's Liberation Army.

Early T-precursor acute lymphoblastic leukemia/lymphoma (ETP-ALL/LBL) is a rare and aggressive subtype of T-cell leukemia with poor prognosis and resistance to standard treatments. We report a 21-year-old male with ETP-ALL/LBL who, after an initial complete remission with the HOELZER protocol, experienced early relapse and was refractory to subsequent FLEND and BFM protocols. Following disease progression and complications, he was treated with a combination of daratumumab, venetoclax, azacitidine, and dexamethasone.

Context: Osteonecrosis (ON) is bone death caused by inadequate blood supply and its optimal management remains uncertain.
Objective: We describe the outcomes of BP (pamidronate) treatment in our patients.
Design: Data regarding clinical, laboratory, magnetic resonance imaging (MRI) studies, and bone mineral density measurements (BMD) were recorded before and one year after treatment (reevaluation).
