摘　　要：目的探讨尿液基细胞学(LBC)靶向的荧光原位杂交(FISH)对膀胱尿路上皮癌(BUC)的诊断价值。方法回顾性收集2020年10月—2022年10月于首都医科大学附属北京天坛医院泌尿外科行膀胱镜检查的128例患者的临床资料。所有患者在行膀胱镜检查前进行尿核基质蛋白22(NMP22)检测、尿LBC检测与尿LBC靶向的FISH检测,以术后病理结果为标准,分析3种检查方法的灵敏度和特异度。结果NMP22、尿LBC与LBC靶向的FISH的灵敏度分别为61.11%、79.17%、82.46%,特异度分别为57.14%、73.21%、86.67%;NMP22、尿LBC的灵敏度在检测高级别BUC时优于低级别,差异有统计学意义(P=0.01,P=0.03);3种方法对肌层浸润性膀胱癌与非肌层浸润性膀胱癌检测的灵敏度比较,差异无统计学意义(P≥0.05)。结论尿LBC靶向的FISH对BUC诊断的灵敏度和特异度较高,尤其是对于低级别BUC,可以作为BUC早期筛查、诊断的重要方法。Objective To explore the diagnostic value of urinary liquid-based cytology(LBC)targeted fluorescence in situ hybridization(FISH)for urothelial carcinoma of the bladder.Methods Nuclear matrix protein 22(NMP22)detection,urinary LBC and FISH were performed in 128 patients.The sensitivity and specificity of the three kinds of tests were analyzed with postoperative pathological results as the gold standard.Results The sensitivity of NMP22,urinary LBC and FISH was 61.11%,79.17%and 82.46%,the specificity was 57.14%,73.21%and 86.67%,respectively.The sensitivity of NMP22 and urinary LBC in detecting high BUC was better than that of low BUC,and the difference was statistically significant(P=0.01,P=0.03).There was no significant difference in the sensitivity of the three tests for the diagnosis of muscle-invasive bladder cancer and non muscle-invasive bladder cancer(P≥0.05).Conclusion Urinary LBC targeted FISH has high sensitivity and specificity in the diagnosis of urothelial carcinoma of the bladder and low-grade urothelial carcinoma.It can be an important method for the early screening and diagnosis of bladder cancer.
