初发T1G3膀胱尿路上皮癌行膀胱全切还是保留膀胱手术?

目的 比较根治性膀胱全切与保留膀胱手术治疗初发T1G3膀胱尿路上皮癌的临床效果.方法 初发T1G3膀胱尿路上皮癌患者113例.男91例,女22例.年龄27～88岁,平均64岁.初次治疗保留膀胱患者81例,行根治性膀胱全切患者32例.采用Kaplan-Meier生存分析及log-rank检验比较2组患者5年总生存率及肿瘤特异性生存率.结果 初次治疗保留膀胱患者81例中行经尿道肿瘤电切术74例、膀胱部分切除7例,术后随访6～140个月,平均64个月,术后5年总生存率为64.2%(52/81),肿瘤特异性生存率为77.8%(63/81).根治性膀胱全切治疗32例,术后随访4～141个月,平均62个月.术后5年总生存率为59.4%(19/32),肿瘤特异性生存率为75.0%(24/32).2组术后5年总生存率及肿瘤特异性生存率比较差异均无统计学意义(P>0.05).结论 保留膀胱手术或根治性膀胱全切治疗初发T1G3膀胱癌,5年总生存率和肿瘤特异性生存率差异无统计学意义.膀胱全切治疗初发T1G3膀胱肿瘤至少有50%的病例有过度治疗的可能.

Management of primary T1G3 bladder cancer: immediate cystectomy or bladder preserving approach?

Objective To compare the long-term outcomes in patients with newly diagnosed stage T1G3 bladder cancer treated with bladder preserving approach and intravesical instillation or im-mediate cystectomy.Methods of 113 patients with a median age of 64 years (range 27 to 88) diag-nosed with T1G3 bladder cancer from January 1993 to February 2007,81 cases were treated by tran-sureteral resection with additional intravesieal instillation and 32 were treated with immediate cystecto-my.Differences between the 2 groups in 5-year overall survival and tumor specific survival were calcu-lated using the Kaplan-Meier survival function and analyzed by the log rank test.Results of 81 pa-tients treated with organ preserving approach and postoperative intravesical instillation,53 patients developed local recurrence and 21 patients underwent deferred cysteetomy in a median 64 (range 6-140) months follow-up.The overall and tumor specific survival at 5 years was 64.2% (52/81) and 77.8%(63/81),and in those who had deferred cystectomy it was 61.9% (13/21) and 76.2% (16/21),respectively.Of the 32 patients treated with immediate cystectomy,the 5-year overall and tumor specific survival was 59.4%(19/32) and 75.0%(24/32) within a median follow-up of 62(range 4-141)months.There was no statistical difference of the 5-year overall and tumor specific survival be-tween patients treated with bladder preserving approach or immediate cystectomy.Conclusion Blad-der preserving approach and immediate eystectomy might have similar 5-year overall and tumor specific survival for primary T1G3 bladder cancers.
