Abstract:
Objective To evaluate the efficacy of partial cystectomy in treatment of localized muscle invasive bladder cancer.Methods From 1999 to 2005,data from 71 patients with muscle invasive bladder cancer(MIBC) were reviewed.There were 47 patients underwent partial cystectomy (PC) and 24 underwent total cystectomy (TC).The overall survival and disease-free survival in patients with MIBC with PC or TC were compared.All patients had pathologic T2-T3.Matched Kaplan-Meier survival analyses compared the effect of PC vs.TC on overall survival and disease-free survival.Univariate (log rank) and multivariate (Cox' proportional hazard model) analyses were used to test the statistical significance of several potential prognostic factors for survival rate.Results In the entire cohort,the overall survival rate and disease-free survival rate estimated at 5 years were 57％ and 50％ for PC patients,53％ and 46％ for TC patients,respectively (P＞0.05).On univariate analysis,T stage (include vessel tumor embolus) and whether the tumor was pedunculated were the significant predictors of tumor recurrence.Age,gender,tumor quantity,tumor size and histology category were not associated with prognosis.Cox proportional hazard regression model confirmed that the independent prognosis factors of tumor was T stage (EXP(B)=1.64,P＜0.05).Conclusions PC might not undermine cancer control in appropriately selected patients with MIBC.
