Abstract: 目的探讨尿端粒酶活性检测在膀胱癌早期诊断及术后复发监测中的意义.方法采用PCR银染法于术前检测85例表浅膀胱癌患者尿液中脱落细胞端粒酶活性,并在行膀胱部分切除或经尿道膀胱肿瘤电切术(TURBt)后3个月和6个月时再检测尿端粒酶活性,同时行膀胱镜检查.结果术前85例表浅膀胱癌患者尿脱落细胞端粒酶活性阳性表达率为81.18%(69/85);术后67例获随访,6个月内尿端粒酶检测持续阳性者复发率为55.56%(20/36),持续阴性者复发率为19.23%(5/26),两组相比有显著性差异(P<0.01);2例3个月为阴性而6个月转阳性者均复发,而3例3个月为阳性而6个月转阴性者均未复发.结论尿脱落细胞端粒酶活性检测可作为表浅膀胱癌早期诊断和术后复发监测的一种有效手段.
