Tumor suppressor genes, treatments, and survival in US veterans with prostate cancer.
Article in The oncologist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundTumor suppressor gene (TSG) alterations prognosticate inferior survival in metastatic hormone-sensitive prostate cancer (mHSPC) and may affect response to therapy. We evaluated the association of TSG alterations with overall survival (OS) in mHSPC, stratified by initial treatment.
methodsWe identified veterans with de novo mHSPC diagnosed from 2017 to 2023 within the Veterans Health Administration. TSG alterations included loss-of-function alterations in RB1, TP53, and PTEN identified by somatic sequencing through the National Precision Oncology Program. Treatments within 4 months of diagnosis included androgen deprivation therapy (ADT), docetaxel, and androgen receptor pathway inhibitors (ARPIs). Kaplan-Meier and Cox models evaluated relationships between TSG alterations, clinical factors, and OS.
resultsAmong 1842 veterans who met criteria, 865 had sequencing within 6 months. TSG alterations were found in 935 veterans, with the most common alterations being TP53 (36.7%), PTEN (23.4%), and RB1 (4.5%). In veterans sequenced within 6 months, RB1, TP53, and PTEN alterations were associated with mortality with a hazard ratio (95% CI) of 2.86 (1.94-4.21) (P < .001), 1.64 (1.30-2.05) (P < .001), and 1.52 (1.20-1.91) (P < .001), respectively. In the same cohort, median OS (95% CI) was 40.7 months (37.5-NR) with no alterations, 34.1 months (30.3-37.3) with 1, and 19.7 months (16.5-25.5) with ≥2 TSG alterations. In veterans with ≥1 alteration and sequencing within 6 months, combination therapy with ARPIs was associated with decreased mortality, aHR (95% CI) of 0.65 (0.48-0.88, P = .005).
conclusionTSG alterations were associated with inferior OS in veterans with mHSPC. In this real-world observational study, ARPI-based combination therapy in veterans with TSG alterations was associated with the longest survival.
