Minimally invasive cytoreductive radical prostatectomy, exploring the safety and feasibility of a single-port or multi-port robotic platform

Abstract

Abstract Background Consolidative resection or cytoreductive radical prostatectomy (CRP) may benefit men with non-organ confined prostate cancer. We report the safety, feasibility, and outcomes of robot-assisted laparoscopic CRP using a single-port (SP) or multi-port (MP) platform. Methods We reviewed consecutive men with clinical node positive or metastatic castrate-sensitive prostate cancer who underwent IRB-approved CRP and extended pelvic lymph node dissection using the da Vinci SP or MP Surgical Systems (Intuitive Surgical, Sunnyvale, CA) from 2015–2022. Perioperative data and Clavien-Dindo 90-day complications were recorded. Results Twenty-four men with a median age of 61 (IQR 56—69) years and prostate-specific antigen of 32.1 (IQR 21.9—62.3) ng/mL were included. Clinical N1, M1, or N1 + M1 disease were detected in 8 (33%), 9 (38%), 7 (29%) patients, respectively. There was no difference in positive margins, 41% vs. 29% (P = 0.67), lymph node yield, 21 (IQR 14–28) vs. 20 (IQR 13.5–21) nodes (P = 0.31), or estimated blood loss, 150 mL (IQR 100–200) vs. 50 mL (IQR 50–125) (P = 0.06), between the MP and SP cohorts, respectively. Hospital length of stay was significantly shorter for the SP group, same-day discharge (IQR 0–0), compared to MP, 1-day (IQR 1–1), P < 0.001. One grade III bowel obstruction and lymphocele occurred in the MP cohort. No major complications occurred in the SP cohort. Conclusion Robot-assisted laparoscopic CRP is safe and feasible for select men with advanced castrate-sensitive prostate cancer.
