Purpose To evaluate the effect of risk factors and selected surgical methods on operative and oncological results of patients undergoing radical prostatectomy (RP) with high-risk prostate cancer (HRPC). Methods Retrospective analysis of patients, who underwent RP for HRPC from 13 urology centers between 1990 to 2019, was performed. Groups were created according to the risk factors of D’Amico classification. Patients with one risk factor were included in group 1 where group 2 consisted of patients with two or three risk factors. Results A total of 1519 patients were included in this study and 1073 (70.6%) patients assigned to group 1 and 446 (29.4%) patients to group 2. Overall (biochemical and/or clinical and/or radiological) progression rate was 12.4% in group 1 and 26.5% in group 2 (p =0.001). Surgical procedure was open RP in 844 (55.6%) patients and minimally invasive RP in 675 (44.4%) patients (laparoscopic and robot-assisted RP in 230 (15.1%) and 445 (29.3%) patients, respectively). Progression rates were similar in different types of operations (p=0.22). Progression rate was not significantly different in patients who either underwent pelvic lymph node dissection (PLND) or not in each respective group. Conclusion RP alone is an effective treatment in the majority of patients with HRPC and PLND did not affect the progression rates after RP. According to the number of preoperative high-risk features, as the number of risk factors increases, there is a need for additional treatment.
