Oncological outcomes, quality of life outcomes and complications of partial cystectomy for selected cases of muscle-invasive bladder cancer

• To evaluate the oncological results, associated complications, and postoperative health-related quality of life (HR-QoL) in patients treated with partial cystectomy (PC) for muscle-invasive bladder cancer (MIBC). 27 patients who underwent open PC for cT2 MIBC were included. A simple Cox’s proportional hazards regression model was used to assess the association of several potential prognostic factors with survival. Postoperative HR-QoL was assessed with the EORTC (European Organisation for the Research and Treatment of Cancer) QLQ-C30 questionnaire version 3.0. Final pathological tumour stages in PC specimen were: pT0: 18.5%, non-MIBC: 3.7%, MIBC: 74.1%, pCIS: 14.8%. Estimated 5-year overall- and progression-free survival rates were 53.7% and 62.1%. Five (18.5%) patients experienced local recurrence with MIBC. Overall, the salvage cystectomy rate was 18.5%. The 90-day mortality rate was 0%. Significant risk factors for progression-free survival were vascular invasion (HR 5.33) and tumour multilocularity (HR 4.5) in the PC specimen, and a ureteric reimplantation during PC (HR 4.53). The rates of intraoperative complications, 30- and 90-day major complications were 7.4%, respectively and 14.8% for overall long-term complications. Postoperatively, median (IQR) global health status and QoL in our PC cohort was 79.2 (52.1–97.9). Open PC can provide adequate cancer control of MIBC with good HR-QoL in highly selected cases. Open PC can lead to long-term bladder preservation and shows an acceptable rate of severe perioperative complications, even in highly comorbid patients.
