Here, we report the results of the prospective cohort study EORTC-CLG 58081 and compare them to the control arm of the randomized phase 3 trial EORTC-CLG 58951, on which treatment recommendations were built. In both studies, patients aged 1-18 years with negative acute lymphoblastic leukemia of the B-lineage (B-ALL) or T-lineage (T-ALL) were treated using a BFM backbone without cranial irradiation. Similarly to the control arm of 58951, prednisolone (PRED) 60 mg/m/day was used for induction therapy, but a few modifications were made.

Article Synopsis
  • The study refines the prediction of outcomes in T-cell acute lymphoblastic leukemia (T-ALL) using next-generation sequencing (NGS) to identify genetic mutations associated with risk levels.
  • A classifier developed through whole-exome sequencing categorized patients into low-risk and high-risk groups based on specific mutations, revealing significant differences in their 5-year cumulative incidence of relapse (CIR).
  • Integrating this genetic stratification with clinical factors like white blood cell counts and minimal residual disease enhances prognosis and identifies potential patients for targeted therapies.

We investigated using a custom NGS panel of 149 genes the mutational landscape of 64 consecutive adult patients with tyrosine kinase fusion-negative hypereosinophilia (HE)/hypereosinophilic syndrome (HES) harboring features suggestive of myeloid neoplasm. At least one mutation was reported in 50/64 (78%) patients (compared to 8/44 (18%) patients with idiopathic HE/HES/HE used as controls; p < .001).

Article Synopsis
  • * In a study of 1091 adult patients, 12.9% had KMT2A-r, with a 5-year relapse rate of 40.7% and overall survival rate of 53.3%. The presence of specific gene alterations like TP53 and IKZF1 correlated with significantly worse outcomes.
  • * The analysis showed that measuring minimal residual disease (MRD) using KMT2A markers was more reliable than other methods, indicating that patients responding well early

Chromosomal rearrangements of the human KMT2A/MLL gene are associated with de novo as well as therapy-induced infant, pediatric, and adult acute leukemias. Here, we present the data obtained from 3401 acute leukemia patients that have been analyzed between 2003 and 2022. Genomic breakpoints within the KMT2A gene and the involved translocation partner genes (TPGs) and KMT2A-partial tandem duplications (PTDs) were determined.
