经尿道膀胱肿瘤电切术后使用吡柔比星或丝裂霉素定期灌注化疗治疗膀胱肿瘤临床研究

目的：对比浅表性膀胱尿路上皮癌在经尿道膀胱肿瘤电切术（TUR-Bt）后使用吡柔比星及丝裂霉素两种药物定期灌注化疗的疗效及安全性。方法：选取浅表性膀胱尿路上皮癌并且行TUR-Bt手术治疗患者42例,随机分为丝裂霉素组、吡柔比星组,每组各21例。吡柔比星组术后使用30mg吡柔比星定期膀胱灌注,丝裂霉素组术后使用20mg丝裂霉素定期灌注肿瘤。观察两组复发及化疗不良反应发生情况。结果：随访时间12~48个月,期间共有3例患者失访,随访3年期间吡柔比星组共复发8例,复发率40.00%,丝裂霉素组共复发15例,复发率71.43%,3年总复发率两组比较差异存在统计学意义;灌注治疗期间不良反应以膀胱刺激症状、恶心、胸闷、心悸、尿道狭窄等最为常见,其中吡柔比星组发生14例次,丝裂霉素组发生22例次,不良反应发生率在两组间比较差异具有统计学意义。结论：在浅表性膀胱尿路上皮癌TUR-Bt术后给予吡柔比星或丝裂霉素两种药物进行定期灌注化疗,两种药物均能起到一定的预防肿瘤复发作用,但以吡柔比星疗效较好,不良反应发生率低。

Evidence-based pharmacoeconomic research of pirarubicin and epirubicin as prophylaxis for recurrence in patients with superficial bladder tumors by bladder instillation after transurethral resection of a bladder tumor

In the present study, we aimed to evaluate the efficiency and cost ofpirarubicin （THP） and epirubicin （EPI） as prophylaxis for recurrence in patients with superficial bladder tumors by bladder instillation after transurethral resection of a bladder tumor （TUR-BT）. Standardized evaluation was performed by analyzing research papers. Moreover, expert opinions, studies and cost data were combined to evaluate cost of THP and EPI. With systematic review and expert opinions, we confirmed that THP and EPI were not statistically different when they were used as prophylaxis for recurrence in patients with superficial bladder tumors by bladder instillation after TUR-BT. Moreover, the cost evaluation of THP and EPI needs to be separately discussed according to original/generic drug. The original drug THP had more cost advantages than EPI, while generic EPI had more cost advantages than THP.
