Brit J Cancer:膀胱癌术后复发的非侵入性预测方法

2017-07-10 zhangfan MedSci原创

尿样中的端粒酶逆转录酶突变测试是膀胱尿路上皮癌复发的早期风险预测指标

膀胱尿路上皮癌(UBC)的特点之一是其复发风险较高。现有的病患监测手段是侵入性的膀胱镜检查或敏感性低的非肌层浸润性膀胱癌尿细胞学检查(NMIBC)。研究表明端粒酶逆转录酶(TERT)激活是膀胱尿路上皮癌的突变启动子。近日研究人员就端粒酶逆转录酶在膀胱尿路上皮癌预后检测中的应用进行了考察。研究招募了348名接受了经尿道膀胱切除术的UBC患者以及167名对照患者,研究人员对尿样TERT突变、细胞学以及膀胱镜检查效果进行了比较。研究发现,研究总的敏感性为80.5%,特异性89.8%并且可排除炎症或感染的影响。手术后TERT阳性与原位残留癌相关。尿样中的TERT是可靠动态的膀胱尿路上皮癌复发预测指标(P<0.0001)。单一变量分析显示,首次术后的TERT阳性状态会导致复发风险增加5.34倍 (P=0.0004)。对于膀胱镜检测阴性的患者,TERT阳性仍与复发相关(P=0.034)。研究表明尿样中的端粒酶逆转录酶突变测试是膀胱尿路上皮癌复发的早期风险预测指标。原始出处:Franoise Descotes et al.
