Acute erythroid leukemia (AEL) is a high-risk leukemia of poorly understood genetic basis, with controversy regarding diagnosis in the spectrum of myelodysplasia and myeloid leukemia. We compared genomic features of 159 childhood and adult AEL cases with non-AEL myeloid disorders and defined five age-related subgroups with distinct transcriptional profiles: adult, TP53 mutated; NPM1 mutated; KMT2A mutated/rearranged; adult, DDX41 mutated; and pediatric, NUP98 rearranged. Genomic features influenced outcome, with NPM1 mutations and HOXB9 overexpression being associated with a favorable prognosis and TP53, FLT3 or RB1 alterations associated with poor survival. Targetable signaling mutations were present in 45% of cases and included recurrent mutations of ALK and NTRK1, the latter of which drives erythroid leukemogenesis sensitive to TRK inhibition. This genomic landscape of AEL provides the framework for accurate diagnosis and risk stratification of this disease, and the rationale for testing targeted therapies in this high-risk leukemia.

Patients who develop acute myeloid leukemia (AML) after having received treatment for myelodysplastic syndrome (MDS) or related conditions have particularly poor outcomes. This study analyzed adult patients with newly diagnosed AML who previously had MDS, chronic myelomonocytic leukemia (CMML), or MDS/myeloproliferative neoplasm (MPN) overlap syndrome, and who had received hypomethylating agents, chemotherapy, and/or allogeneic stem cell transplantation (HSCT) for these antecedent disorders. From January 2012 to August 2023, we included 673 patients with a median age of 70 years (range, 19-94); 536 (80%) had transformed from MDS, and the remainder from CMML or MDS-MPN.

Introduction: Acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) constitute myeloid malignancies, and allogeneic hematopoietic stem cell transplantation (allo-HSCT) is considered as a potentially optimal approach for achieving a long term cure. However, post-allo-HSCT relapse remains a leading cause of mortality and therapeutic failure.
Methods: To evaluate the efficacy and safety of combining hypomethylating agents (HMAs) with Bcl-2 inhibitors in the treatment of AML/MDS relapse following allo-HSCT, we retrospectively collected data from 42 patients who experienced relapse between April 2012 and March 2022 at Peking University First Hospital.

Pediatric hematology/oncology as a subspecialty has made major contributions to the diagnosis and treatment of acute lymphoblastic leukemia, the most common malignancy in the pediatric population. This impressive progress has yielded complete response rates of 98%, median durations of complete continuous remissions of over 5 years, and long-term leukemia-free survival and probable cure in 80% to 85% of patients. Sixty-five years ago, such data could only be imagined as future goals.

Context.—: Blasts in myelodysplastic syndromes (MDSs) typically have a primitive myeloid immunophenotype (CD34+CD117+CD13+CD33+HLA-DR+). On rare occasions, blasts were found to be CD34 negative or minimally expressed in a presumptive MDS.

Background: The management of relapsed acute lymphoblastic leukemia (ALL) after hematopoietic stem cell transplantation (HSCT) has evolved significantly. Initially, treatment options were limited to palliative care, salvage chemotherapy, and second HSCT. Currently, the focus has shifted to innovative immunotherapies, particularly CAR T-cell therapy.
