Correlation of intraprostatic lesional SUVmax during PSMA PET/CT and adverse pathology at radical prostatectomy.
Article in Prostate cancer and prostatic diseases, 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
objectiveProstate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) is a novel staging modality for prostate cancer (PCa) patients with a high positive predictive value for lesions within and outside of the prostate. To assess the ability of the maximum standardized uptake value (SUVmax) at PSMA PET/CT to predict adverse pathology at radical prostatectomy (RP). MATERIAL AND
methodsWithin a high-volume center database, we identified intermediate and high-risk PCa patients who had a PSMA PET/CT with an available intraprostatic SUVmax before RP between 2016 and 2021. Logistic regression modeling was used to test for the ability of SUVmax to predict non-organ confined disease or adverse pathology (non-organ confined and/or Gleason grade group ≥3) during RP. Kaplan-Meier analyses were used to compare biochemical recurrence (BCR)-free survival after RP stratified according to SUVmax.
resultsOverall, 544 patients were identified. Of those, median lesional intraprostatic SUVmax was 9.5 at PSMA PET/CT. Median PSA was 8.1 ng/ml prior to RP. 50.7% vs. 49.3% had D'Amico intermediate and high-risk characteristics. Median follow-up was 24.6 months. BCR-free survival at 48 months after RP was 72.1% vs. 62.2% (p = 0.03) for patients with SUVmax <9.5 vs. SUVmax ≥9.5 at PSMA PET. In logistic regression models, SUVmax (continuously coded and stratified in <9.5 vs. ≥9.5) represented an independent predictor for non-organ confined disease and adverse pathology.
conclusionsSUVmax ≥9.5 at PSMA PET/CT is an independent predictor of adverse pathology at RP. Moreover, it is associated with worse BCR-free survival after RP.
