Mutational landscape changes of AML in patients relapsing after allogeneic hematopoietic cell transplantation.
Article in Bone marrow transplantation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Relapse of acute myeloid leukemia (AML) following allogeneic hematopoietic cell transplantation (allo-HCT) remains a life-threatening complication and is influenced by the underlying biology of the AML and possibly by genetic alterations. In this retrospective multicenter study, we evaluated mutational dynamics of AML cells in 57 patients with relapse after allo-HCT. We observed that 68% of patients exhibited genetic instability, characterized by acquisition or loss of mutations, most frequently involving FLT3-ITD, NRAS, and KRAS, while founding lesions such as DNMT3A were usually retained. Clonal evolution patterns varied, with constant profiles (35.0%), linear (29.8%), branching (22.8%), and parallel (12.3%) evolution. However, these evolutionary categories were not associated with differences in progression-free or overall survival. In contrast, relapse timing was highly prognostic: early relapse ( ≤ 6 months) conferred a significant higher mortality risk compared to late relapse, independent of evolution model. Our findings indicate that while relapse after allo-HCT in AML is genetically diverse, timing of recurrence remains the most critical determinant of outcome. Given that certain genetic changes may inform therapeutic options, these findings highlight the relevance of longitudinal molecular monitoring especially during the early post-transplant period.
