Comprehensive omics-based classification system in adult patients with B-cell acute lymphoblastic leukemia.
Article in Molecular oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
B-cell acute lymphoblastic leukemia (B-ALL) is a highly heterogeneous disease with a challenging prognosis, particularly in adult patients. We enrolled 88 adult B-ALL patients with transcriptomic and mutation profiles for classification system identification, and a comprehensive system for B-ALL patients (COMBAT) was developed. COMBAT stratified patients into three cohorts: (1) COMBAT1, characterized by high stem/myeloid antigen expression, low immune infiltration, high infiltration of endothelial cells, and hypo-CIMP (CpG island methylator phenotype); (2) COMBAT2, defined as an inflamed subtype with immune exhaustion, moderate myeloid antigen expression, and hypo-CIMP; and (3) COMBAT3, marked by proliferative profiles with MYC pathway activation and hypomethylation at enhancer regions in patients characterized by CIMP. The molecular features of the three COMBATs were verified in two external cohorts, the GSE34861 (N = 194) and GSE66005 (N = 109) datasets. In univariate analysis, only COMBAT classification presented significance for OS, and patients of COMBAT3 presented significantly superior survival than COMBAT1/2 in Ph-negative ALL. Ph-negative ALL patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the COMBAT3 group showed better overall survival (OS) than those in the COMBAT1-2 groups (estimated 3-year OS: 100% vs. 65.6%, P = 0.034), suggesting a prognostic benefit of this subtype. In summary, the COMBAT system redefines the characteristics of adult B-ALL subtypes and guides the selection of allo-HSCT for Ph-negative patients.
