Prognostic impact of TET2 mutations in patients with acute myeloid leukemia: HM-SCREEN-Japan 01 and 02 study.
Article in Annals of hematology, 2025. 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
Ten-eleven translocation-2 (TET2) gene mutations are observed in 12-20% of adult patients with acute myeloid leukemia (AML). The prognostic impact of TET2 mutations in patients with AML and myelodysplastic syndromes has been reported in several studies; however, their results remain controversial. Therefore, we aimed to analyze the prevalence and significance of TET2 mutations in patients with AML. Data were obtained from 331 patients with AML according to the Hematologic Malignancies-SCREEN-Japan 01 and 02 studies, which were prospective multicenter genomic profiling analyses. We found a distinct type of TET2 mutations, with a particularly detrimental prognosis in the patients. Thirty-five patients with TET2 'significant' mutations were identified (26 with frameshift mutations and nine with nonsense mutations). The proportion of patients with TET2 mutations was 31.7% (10.6% and 21.1% in the TET2 significant and non-significant mutation groups). The TET2 significant mutation group had a shorter OS than the TET2 non-significant mutation or wild-type TET2 group (median: 15.9 vs. 35.0 vs. 25.9 months). Regarding the response to chemotherapy according to TET2 status, the complete response (CR) or CR with incomplete count recovery rate was 37.1% in the TET2 significant mutation group and 46.6% in the non-significant mutation or wild-type group. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) improved patient prognosis in the TET2 non-significant mutation or wild-type TET2 group; however, allo-HSCT did not affect prognosis in the TET2 significant mutation group. This study indicates that certain TET2 mutations in patients with AML may have detrimental effects.
