Abstract: 目的探讨膀胱内灌注纤维蛋白溶解抑制药物增强卡介苗(BCG)预防膀胱癌术后复发的疗效.方法将208例浅表性膀胱移行细胞癌(BTCC)患者术后随机分成5组,A组44例,定期膀胱内灌注BCG 100~120 mg+氨甲苯酸(PAMBA)0.1 g+生理盐水,B组41例,灌注BCG 50~60mg+PAMBA 0.1 g+生理盐水,C组41例,灌注BCG 100~120 mg+氨基己酸(EACA)2.0 g+生理盐水,D组39例,灌注BCG 50~60 mg+EACA 2.0 g+生理盐水,E组43例,灌注BCG 100~120 mg+生理盐水.每周1次,6次后每月1次.灌注后每3个月作膀胱镜检查,必要时取活检明确肿瘤有无复发.结果随访4~58个月,平均22个月,A~E组BTCC复发率分别为10.3%、8.6%、9.7%、9.7%和29.7%.A、B、C、D各组抗BTCC复发的疗效均明显优于E组(对照组),差异有统计学意义(P<0.05);B、D组预防BTCC术后复发的效果与A、C组比较差异无统计学意义.结论膀胱内灌注纤维蛋白溶解抑制药物PAMBA、EACA可增强BCG预防膀胱癌术后复发的疗效,BCG剂量减半后,疗效不降低.
