Objective:To investigate the correlation between overall recurrence rate

survival rate

and the first recurrence duration and operative methods

and to discuss the strategy of bladder-preserving for patients with bladder transitional cell carcinoma(TCC).Methods:A total of 249 cases of bladder tumor with complete follow-up data

treated from 1991 to 2005 in our hospital

were studied re trospectively.The correlation between overall recurrence rate

survival rate and the first recurrence duration and operative methods were analyzed by the life table method

and statistical methods

like Newman-Keuls and chi-square test.Result:The first recurrence duration was not influenced by operative methods. There was no significant difference of overall recurrence rate and short-term survival rate(3-year and 5-year)among different operative methods

the highest 10-year survival rate(77.3%)occurred in the group of transurethral resection of bladder tumor(TURB)and the lowest one(65.2%)in the group of partial cystectomy

and the difference was statistically significant.Conclusions:TURB could achieve the same short-term therapeutic effect as opening operations(partial resection of bladder or resection of bladder tumors)and the higher long-term survival rate can be obtained by TURB.
