再次经尿道电切术治疗非肌层浸润性膀胱癌

Repeat transurethral resection for non-muscle invasive bladder cancer

摘要:

目的 总结再次经尿道电切术(Re-TUR)治疗非肌层浸润性膀胱癌的疗效.方法 2004年3月至2008年8月共收治462例非肌层浸润性膀胱癌,男性350例,女性112例,年龄35~83岁.在初次经尿道电切术后根据肿瘤分期和分级,以及标本有无肌层组织进行评估,有125例患者在术后4~6周行Re-TUR,其中Ta期49例,T1期76例;低级别癌58例,高级别癌67例;T1期肿瘤标本内未见肌层组织30例.结果 125例非肌层浸润性膀胱癌患者行Re-TUR,34.4%(43/125)发现有肿瘤残留,其中35例肿瘤未侵犯肌层,Ta期15例,T1期20例;8例肿瘤侵犯肌层.高级别癌的肿瘤残留率较低级别癌高(P<0.05);初次电切标本中无肌层的肿瘤残留率较有肌层的高(P<0.05).12例(9.6%)患者在初次电切术时肿瘤分期被低估.Re-TUR术中发生膀胱穿孔6例,膀胱出血7例.随访3~56个月;Re-TUR发现肿瘤残留的患者,37.2%(16/43)复发,高于Re-TUR未发现肿瘤残留的患者(12.2%,P<0.05).结论 T1期、高级别或初次电切标本无肌层的非肌层浸润性膀胱癌患者术后4~6周应行Re-TUR.Re-TUR能提高分期的准确性.

Objective To investigate the efficacy of repeat transurethral resection of tumor in patients with non-muscle invasive bladder cancer. Methods From March 2004 to August 2008, 462 patients (350 males, 112 females, aged from 35 to 83 years old) with non-muscle invasive bladder cancer, were evaluated according to tumor stage, grade and muscle or no muscle tissue in initial transurethral resected sample. One hundred and twenty-five patients underwent repeat transurethral resection of bladder tumor within 4 to 6 weeks after initial resection. Of these 125 patients 49 were Ta, 76 were T1, 58 were low grade carcinoma, 67 were high grade carcinoma and 30 were not found presence of muscle tissue in initial resected sample in patients with T1 stage. Results Of the 125 cases, 34.4% (43/125) had residual tumor and 65.6% (82/125) had no tumor on repeat transurethral resection. Of 43 cases with residual tumor 35 had non-muscle invasive tumor including 15 in Ta and 20 in T1. The patients with high grade carcinoma had more residual tumor than those with low grade carcinoma (P<0.05). The patients with muscle tissue in initial transurethral resected sample had fewer residual tumor than those without (P<0.05). Twelve cases (9.6%) were understaged at initial resection. Six cases (4.8%) had bladder perforation and 7 (5.6%) had bleeding during repeat transurethral resection. All cases were followed up for 3 to 56 months (median 26 months), 37.2% (16/43) patients with residual tumor in repeat transurethral resection had recurrence while only 12.2% (10/82) without residual tumor in repeat transurethral resection did (P<0.05). Conclusions Routine repeat transurethral resection is advised to non-muscle invasive bladder cancer patients with T1 tumor or high grade carcinoma or no muscle tissue in initial transurethral resected sample within 4 to 6 weeks after initial resection. Repeat transurethral resection could increases the stage accuracy.
