Primary Score as a Predictive Marker in Intermediate-Risk Prostate Cancer: Insights from PSMA PET/CT Imaging.
Article in Nuclear medicine and molecular imaging, 2025. 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
Purpose: This study aimed to determine whether the PRIMARY Score on prostate specific membrane antigen (PSMA) positron emission tomography/compute tomography (PET/CT) can predict adverse pathology and prognosis in patients with intermediate-risk prostate cancer (PCa). Materials and methods: This is a retrospective, multicenter analysis of patients diagnosed with intermediate risk PCa. Patients were staged using pelvic multiparametric magnetic resonance imaging (mpMRI) and radiolabeled PSMA PET/CT, either [68 Ga]Ga-PSMA-11 or [18F]F-PSMA1007, to evaluate the extent of disease before initiating appropriate treatment. PI-RADS Version 2.1 and PRIMARY score were used for a quantitative analysis, respectively for mpMRI and PSMA PET/CT. Biochemical recurrence of disease was defined as a post-operative serum PSA > 0.2 ng/ml on two separate occasions at minimum 2-week intervals. Results: Seventy-eight intermediate-risk PCa patients were enrolled. PRIMARY scores > 3 was found in 62% of favorable (n = 50) and 71% of unfavorable cases (n = 28). Gleason score changes occurred in 20% of favorable-risk patients, with 90% having a PRIMARY score > 3. Biochemical recurrence was observed in 17% of patients during follow-up, predominantly among favorable-risk cases (13%), where most had Gleason score changes and a PRIMARY score > 3. Conclusions: These results highlight the predictive value of the PRIMARY score for Gleason score changes.
