Abstract

OBJECTIVES:

To analyze pathological and short-term oncological outcomes in men undergoing open and minimally-invasive radical prostatectomy (MIRP) for high-risk prostate cancer (HRPC; prostate-specific antigen level [PSA] >20 ng/mL, ≥ cT2c, Gleason score 8-10) in a contemporaneous series.

PATIENTS AND METHODS:

In total, 913 patients with HRPC were identified in the Johns Hopkins Radical Prostatectomy Database subsequent to the inception of MIRP at this institution (2002-2011) Of these, 743 (81.4%) underwent open radical retropubic prostatectomy (ORRP), 105 (11.5%) underwent robot-assisted laparoscopic radical prostatectomy (RALRP) and 65 (7.1%) underwent laparoscopic radical prostatectomy (LRP) for HRPC. Appropriate comparative tests were used to evaluate patient and prostate cancer characteristics. Proportional hazards regression models were used to predict biochemical recurrence.

RESULTS:

Age, race, body mass index, preoperative PSA level, clinical stage, number of positive cores and Gleason score at final pathology were similar between ORRP and MIRP. On average, men undergoing MIRP had smaller prostates and more organ-confined (pT2) disease (P = 0.02). The number of surgeons and surgeon experience were greatest for the ORRP cohort. Overall surgical margin rate was 29.4%, 34.3% and 27.7% (P = 0.52) and 1.9%, 2.9% and 6.2% (P = 0.39) for pT2 disease in men undergoing ORRP, RALRP and LRP, respectively. Biochemical recurrence-free survival among ORRP, RALRP and LRP was 56.3%, 67.8% and 41.1%, respectively, at 3 years (P = 0.6) and the approach employed did not predict biochemical recurrence in regression models.

CONCLUSIONS:

At an experienced centre, MIRP is comparable to open radical prostatectomy for HRPC with respect to surgical margin status and biochemical recurrence.
