Correlations between whole body volumetric parameters of 68Ga-PSMA PET/CT and biochemical-histopathological parameters in castration-naive and resistant prostate cancer patients.

Wbv 68Ga-PSMA PET/CT results were correlated with PSA levels and Gleason scores. The correlation was relatively stronger in the castration-naive group. The prognostic accuracy of PSA in the resistant group may be weaker than in the naive group. The difference in volumetric parameters of patients with short BR compared to long BR supports the idea that 68Ga-PSMA PET/CT can distinguish patients with rapid relapse from others.
