The appropriateness of PSMA PET/CT in newly diagnosed unfavorable intermediate-risk prostate cancer patients—towards a tumor volume-based risk stratification

Abstract

Background/objectives

This study reassesses the diagnostic value of PSMA PET/CT in unfavorable intermediate-risk prostate cancer (PCa) and validates the Prostate Cancer Network the Netherlands (PCNN) subclassification.

Subjects/methods

Men subjected to PSMA PET/CT were analyzed, evaluating the incidence of metastatic disease and its correlation with PCNN subgroups.

Results

Metastatic disease was identified in 12.4% of patients. Higher PCNN subgroups correlated with increased metastatic potential; odds were significantly lower in low metastatic potential cases (OR: 0.19, 95% CI 0.06–0.62; p = 0.01).

Conclusions

Our findings reaffirm PSMA PET/CT’s diagnostic value in unfavorable intermediate-risk PCa and validate the PCNN subclassification, reducing scan burden by 48.1%.
