Abstract

Purpose: Comparative data related to the use of open and minimally invasive surgical approaches for the treatment of high-risk prostate cancer (PCa) remain limited. We determined outcomes of open radical prostatectomy (RRP), laparoscopic RP (LRP), and robot-assisted RP (RARP) in matched cohorts of patients with high-risk prostate cancer.

Materials and methods: A total of 805 patients with high-risk PCa [prostate-specific antigen (PSA) >20 ng/mL, Gleason score ≥8, or clinical stage ≥cT2c] were identified. A total of 407 RRP cases were propensity score (PS) matched 1:1 to 398 LRP or RARP cases to yield 3 cohorts (RARP, LRP, and RRP) of 110 patients each for analysis. PS matching variables included the following: age, clinical stage, preoperative PSA, biopsy Gleason score, surgeon experience, and nerve-sparing technique. Overall survival (OS) and recurrence-free survival (RFS) were compared with log-rank test. RFS predictor analysis was calculated within Cox regression models.

Results: Pathological Gleason scores <7, =7, and >7 were found in 3.3, 50.9, and 45.8 % of patients. There were no statistically significant differences for pathological stage and positive surgical margins between surgical techniques. Mean 3-year RFS was 41.4, 77.9, and 54.1 %, for RARP, LRP, and RRP, respectively (p < 0.0001 for RARP vs. LRP). There were no significant differences for mean estimated 3-year OS for patients treated with RARP, LRP, or RRP (95.4, 98.1, and 100 %).

Conclusions: RARP demonstrated similar oncologic outcomes compared to RRP and LRP in a PS-matched cohort of patients with high-risk prostate cancer.
