本研究目的是检验淋巴结转移性膀胱癌行根治性膀胱切除(RC)术后接受化疗的效果。德国2家协作中心,1993年至2007年行RC治疗膀胱尿路上皮癌或退行分化癌592例,患者中位年龄68岁,随访中位时间6.4年,其中淋巴结转移146例,146例中接受化疗者82例(主要是顺铂为基础的化疗)。使用Kaplan-Meier方法测定总存活率,借助竞争性危险分析癌特异性死亡率,并与2个大样本未接受化疗结果的文献比较(Ghoneim.J Urol,2008:121;Hautmann.Eur
The purpose of this study was to examine the efficacy of chemotherapy after radical cystectomy (RC) in patients with metastatic lymph node metastases. Two collaborating centers in Germany, from 1993 to 2007, treated 592 patients with bladder urothelial carcinoma or dedifferentiated carcinoma with a median age of 68 years. The median follow-up time was 6.4 years, of which 146 were lymph node metastases and 146 were intermediate Chemotherapy in 82 cases (mainly cisplatin-based chemotherapy). Total survival was measured using the Kaplan-Meier method, cancer-specific mortality was analyzed by competitive risk and compared to the literature in which two large samples were not receiving chemotherapy results (Ghoneim.
