Summary

Prostate cancer (PCa) is one of the most frequently diagnosed malignancies in men worldwide, with the highest prevalence observed in developed countries. Patients affected by localized disease can be treated with several local modalities, including radical prostatectomy (RP), external beam radiotherapy (EBRT) and brachytherapy (BT). Although the advances in treatment strategies, after primary treatment 5 to 60% of men experience biochemical recurrence (BCR).
