Homologous recombination repair status in advanced endometrial cancer: an exploratory biomarker analysis from the randomized, phase II MITOEND 3 trial.
Trial report in ESMO open, 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
backgroundPoly (ADP-ribose) polymerase (PARP) inhibitor use in endometrial cancer (EC) requires predictive biomarkers, currently lacking in clinical practice. This study assessed the incidence of homologous recombination deficiency (HRD) using genomic loss of heterozygosity (gLOH) and a machine learning-based HRD scar signature (HRDsig). PATIENTS AND
methodsMITO END 3 was a multicenter, phase II trial of advanced EC patients randomly assigned to receive platinum-based chemotherapy ± avelumab. Of 125 patients, 102 had tumor samples available for sequencing with FoundationOne®CDx. HRD was evaluated using gLOH (cut-off ≥16%, based on ARIEL3) and HRDsig (cut-off ≥0.7, validated pan-cancer).
resultsAmong 102 evaluable samples, 5 were HRDsig-positive, 90 HRDsig-negative, and 7 HRDsig unknown. gLOH was high in 10 cases, low in 53, and not assessable in 39. Most HRDsig-positive (4/5) and gLOH-high (8/10) tumors were of endometrioid histology and carried TP53 mutations. None were microsatellite instability-high.
conclusionsA small subgroup of advanced EC patients shows HRD positivity by gLOH or HRDsig, potentially identifying those most likely to benefit from PARP inhibitors. These tumors are typically endometrioid with TP53 mutations.
