Laparoscopic versus open radical cystectomy in 607 patients with bladder cancer: Comparative survival analysis

Objectives To compare perioperative and oncologic survival outcomes between laparoscopic radical cystectomy and open radical cystectomy. Methods A total of 607 patients underwent open radical cystectomy (n = 412) or laparoscopic radical cystectomy (n = 195) at a single academic institution from January 2006 to April 2017. Their medical records were retrospectively analyzed. One‐to‐one propensity score matching was carried out to reduce selection bias. Estimated blood loss and complications were compared. Overall survival, cancer‐specific survival and progression‐free survival estimates for all patients and patients with locally advanced bladder cancer were analyzed using the Kaplan–Meier method. Results Either before or after matching, the laparoscopic radical cystectomy group had less estimated blood loss (P
