输尿管镜活检是否影响上尿路上皮癌在膀胱内的复发?

2021-09-14 泌尿小王 MedSci原创

很早之前,泌尿科医生根据放射学怀疑UTUC和/或尿细胞学检查结果来决定是否进行根治性肾RNU。后来,输尿管镜活检(Bx)的应用使得UTUC诊断模式发生了转变,但是该诊断方法是否导致复发依然存在差异。

很早之前,泌尿科医生根据放射学怀疑UTUC和/或尿细胞学检查结果来决定是否进行根治性肾RNU。后来,输尿管镜活检(Bx)的应用使得UTUC诊断模式发生了转变,但是该诊断方法是否导致复发依然存在差异。

近日,《The Journal of Urology》发表了一篇研究显示:Bx会导致UTUC患者们在接受RNU,而临床试验证明输尿管镜活检后进行膀胱内化疗的可以减少IVR。

方法

1995年至2019年在接受RNU的患者按照UTUC诊断方式进行分类:

1)无输尿管镜或经皮活检;

2)经皮活检;

3)输尿管镜无活检;

4)输尿管镜活检

采用固定效应荟萃分析将第4组和第1组的结果与文献合并。

 

结果

两年内IVR率

组1内人数(N=210,25.2%),而两年内 IVR 率 15.0%

组2内人数(N=57,6.6%),而两年内 IVR率12.7%

组3内人数(N=125,15.0%),而两年内 IVR率18.4%

组4内人数(N=442,53.0%), 而两年内IVR率21.9% ; 没有统计学差异(见下图)。

检查方法之间的比较

多变量分析发现,与组1相比,组4膀胱内复发增加(HR 1.40, p=0.04),而组2和组3没有增加。

Meta分析

在包括其他11个系列的meta分析中,输尿管镜活检与膀胱内复发相关(HR 1.47, p<0.01)。

 

结论

RNU前UTUC的输尿管镜活检与膀胱内复发风险增加相关,可能是因为UTUC操作增加下游尿路上皮肿瘤播散。
