Abstract:
Objective This study aims to investigate the prognostic factors affecting the survival of patients with local muscle-invasive bladder cancer.
Methods The clinical and follow-up data of 133 patients with local muscle-invasive bladder cancer were retrospectively analyzed. Fourteen possible prognostic factors included gender, age, nationality, smoking habits, alcohol drinking habits, coexisting disease, hydronephrosis, tumor size, multifocality, T stage, lymph node staging, pathological type, histological grade, treatments via the Kaplan-Meier method, or the Log-rank test. Multivariate analysis was performed using the Cox proportional hazard model.
Results The follow-up period ranged from 4 months to 114 months. The 1-, 3-, and 5-year survival rates were 77%, 64%, and 52%, respectively. Univariate analysis showed that the T stage, lymph node staging, and hydronephrosis were prognosis factors (P < 0.05). Multivariate analysis by the Cox proportional hazard model showed T stage (RR = 2.001, P = 0.001), lymph node staging (RR = 2.250, P = 0.045), and hydronephrosis (RR = 1.954, P = 0.047) as the prognostic factors (P < 0.05).
Conclusion Hydronephrosis, T stage, and lymph node staging were prognostic factors of local muscle-invasive bladder cancer.
