The Utility and Efficacy of Laparoscopic Radical Cystectomy in Patients with Muscle-Invasive Bladder Cancer at a Single Institution.

ABSTRACT

BACKGROUND: The aim of this study was to compare the surgical and oncological outcomes and complications of laparoscopic radical cystectomy (LRC) to those of open radical cystectomy (ORC) in patients with muscle-invasive bladder cancer (MIBC). METHODS: Our study focused on patients with histologically confirmed stage T2-T4a urothelial carcinoma of the bladder without distant metastases, who underwent LRC (LRC group) or ORC (ORC group). The primary endpoints in this study were the overall survival (OS) and recurrence-free survival (RFS) rates. RESULTS: In this study, 59 patients, 17 underwent LRC and 42 underwent ORC, were enrolled. The 2-year OS rate was 100% in the LRC group and 88.0% in the ORC group (p = 0.85). The 2-year RFS rate was 63.5% in the LRC group and 69.5% in the ORC group (p = 0.321). On multivariate analysis, the histological type, positive lymph node, and positive resection margin were significantly associated with the OS rates. CONCLUSIONS: This study suggested that LRC may achieve similar oncological outcomes and fewer perioperative complications and less blood loss compared to ORC. Therefore, LRC should be considered as one of the treatment options for patients with MIBC.
