Objective: To investigate oncological outcomes in patients with bladder cancer who underwent minimally invasive radical cystectomy (MIRC) or open radical cystectomy (ORC). Methods: We identified patients with bladder cancer who underwent radical cystectomy (RC) in 13 centers of the Chinese Bladder Cancer Consortium (CBCC). Perioperative outcomes were compared between MIRC and ORC. The influence of surgical approaches on overall survival (OS) and cancer-specific survival (CSS) in the entire study group and subgroups classified according to pathologic stage or lymph node (LN) status was assessed with the log-rank test. Multivariable Cox proportional hazard models were used to evaluate the association among OS, CSS and risk factors of interest. Results: Of 2 098 patients who underwent RC, 1 243 patients underwent MIRC (1 087 laparoscopic RC and 156 robotic-assisted RC, respectively), while 855 patients underwent ORC. No significant differences were noted in positive surgical margin rate and 90-day postoperative mortality rate. MIRC was associated with less estimated blood loss, more LN yield, higher rate of neobladder diversion, longer operative time, and longer length of hospital stay. There was no significant difference in OS and CSS according to surgical approaches (pZ0.653, and 0.816, respectively). Subgroup analysis revealed that OS and CSS were not significantly different regardless of the status of extravesical involvement or LN involvement. Multivariable Cox regression analyses showed that the surgical approach was not a significant predictor of OS and CSS. Conclusions: Our study showed that MIRC was comparable to conventional ORC in terms of OS and CSS. (C) 2020 Editorial Office of Asian Journal of Urology. Production and hosting by Elsevier B.V.
