Comparison of the overall survival of different treatment methods in patients with Muscle-invasive bladder cancer: A retrospective study.

Objectives: Bladder-Sparing Approach was presented in patients who are not willing or not suitable for Radical Cystectomy (RC). There have been inconsistencies in the literature regarding the comparison of survival rates of these two methods. Our objective is to evaluate the survival rate of patients with muscle-invasive bladder cancer (MIBC) undergoing different treatment methods. Design: Retrospective cross-sectional study. Setting: A secondary care, multicenter study in Kerman, Iran 2008 to 2016. Participants: All 200 patients who were diagnosed with Muscle Invasive Bladder Cancer and were admitted to our hospitals. Patients with inaccessible medical files and patients with pathologies other than TCC were excluded. Main outcome measures: Radical cystectomy and different methods of bladder preservation were compared based on their survival rate. Interventions: Radical cystectomy or bladder preservation Results: Overall survival of the patients was 2 years [95% CI: 1.37–2.63]. The overall 5-year survival rate of patients with MIBC was 32%. Having a 6.4 years overall survival, the RC group showed the highest survival compared with others (p = 0.01); the overall survival of patients undergoing TMT, TURT, chemotherapy, or radiotherapy monotherapy was 3.15 years [95% CI: 2.242–4.061], 4.06 [95% CI: 3.207–4.931], 2.58 [95% CI: 1.767–3.399], and 3.14 [95% CI: 1.614–4.672] years, respectively. Patients younger than 65 undergoing RC had an overall survival of 7 years, compared with 2 years for the TMT group. (p = 0.0001). Conclusions: The Bladder-Preservation method, as a replacement for RC, showed a lower overall survival rate in our study. A prospective randomized clinical trial may declare the best treatment.
