Geneva Homologous Recombination Deficiency Test Is Predictive of Survival Benefit From Olaparib and Bevacizumab Maintenance in Ovarian Cancer.
Trial report in JCO precision oncology, 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
purposeThe ability of the Geneva homologous recombination deficiency (HRD) test to predict progression-free survival (PFS) in patients with high-grade ovarian cancer treated with poly (ADP-ribose) polymerase inhibitors has been demonstrated. Its performance with respect to overall survival (OS) has not been assessed yet.
methodsUsing the final results of the PAOLA-1/ENGOT-ov25 phase III clinical trial with a median follow-up of 5 years, we evaluated the Geneva HRD test on 468 samples as part of the ENGOT HRD European Initiative. Results were evaluated in terms of final PFS and OS in the olaparib + bevacizumab and placebo + bevacizumab arms and compared with the Myriad MyChoice HRD test.
resultsFinal PFS was consistent with previously published data and confirmed the predictive value of the Geneva HRD test with a hazard ratio (HR) of 0.41 (95% CI, 0.30 to 0.57) for HRD-positive patients. The results for OS showed a HR of 0.56 (95% CI, 0.37 to 0.85) for HRD-positive patients and 1.6 (95% CI, 1.1 to 2.3) for HRD-negative patients. These results are consistent with those observed with the Myriad test, including the negative OS trend in the HRD-negative subgroup treated with olaparib + bevacizumab (HR, 1.2 [95% CI, 0.83 to 1.8]). A subgroup analysis of patients with intermediate HRD scores showed that the normalized large-scale state transition score used by the Geneva HRD test had both predictive and prognostic value.
conclusionThe Geneva HRD test predicts PFS and OS benefit from olaparib + bevacizumab. The potential detrimental effect of olaparib + bevacizumab on OS in the HRD-negative population is hypothesis-generating and needs to be confirmed prospectively.
