[Current value of seminal vesicle biopsy in patients with prostate cancer and influence of radical prostatectomy in patients with seminal vesicle invasion].

Objectives: To evaluate if radical prostatectomy may positively influence cancer-specific survival (CSS), hormone-resistance-free time, metastasis-free time, and quality of life(QoL) of patients with prostate adenocarcinoma and seminal vesicle invasion, and also to update our thoughts about seminal vesicle biopsy.

Methods: 114 patients were included. Forty-six cases were diagnosed of seminal vesicle invasion after radical prostatectomy; 68 cases were diagnosed of seminal vesicle invasion after biopsy, not undergoing then surgery.
