ABSTRACT
(Objective) We retrospectively analyzed clinical outcome, prognostic factors and adjuvant chemotherapy for bladder cancer patients with open radical cystectomy (ORC) combined with ileal conduit construction (ICC). (Patients and methods) From February 2005 to February 2019, 179 patients underwent ORC and ICC for invasive bladder cancer or BCG unresponsive non-muscle invasive bladder cancer. We investigated intraoperative and early postoperative complications, overall survival (OS), cancer-specific survival (CSS), and poor prognostic factors affecting OS. Furthermore, we evaluated the prognosis of patients with pT3,4 or pN1-3 depending on adjuvant chemotherapy. (Results) Clavien-Dindo Grade 4 or 5 complications were not occurred. The 5-year and 10-year OS probability were 71.1% and 57.4%, respectively, while the 5-year and 10-year CSS probability were 76.5% and 71.5%, respectively. Multivariate analysis revealed that male (HR = 2.70, 95%CI [0.97-7.51]), pT3,4 (HR = 1.83, 95%CI [1.05-3.21]), and pN1-3 (HR = 2.85, 95%CI [1.62-5.03]) were independent poor prognostic factors. Adjuvant chemotherapy significantly improved OS (p = 0.03) and CSS (p = 0.017) in pN1-3 patients. (Conclusion) ORC combined with ICC was an effective operative method, and good results were obtained. Adjuvant chemotherapy may be effective for patients with positive regional lymph nodes.
