摘要

背景与目的：

尿路上皮癌是泌尿系统常见的恶性肿瘤，其早期诊断对改善患者预后至关重要。本研究比较了荧光原位杂交（fluorescence

in situ

hybridization，FISH）、尿脱落细胞学及二者联合检测在尿路上皮癌及其不同亚型中的诊断效能。

方法：

本研究纳入了2022年1月—2023年12月行经尿道膀胱肿瘤切除术（transurethral resection of bladder tumor，TURBT）且符合入组标准及排除标准的患者，且获得复旦大学附属肿瘤医院伦理委员会批准（伦理批号：050432-4-2307E）。收集患者本次TURBT后病理学诊断结果及术前1周的FISH和脱落细胞学检测结果，对FISH、脱落细胞学及二者联合检测在尿路上皮癌中的诊断准确率、灵敏度和特异度进行统计学分析。本研究属于观察性研究，严格遵循《加强流行病学中观察性研究报告质量》（Strengthening the Reporting of Observational Studies in Epidemiology，STROBE）指南及《诊断准确性研究报告规范》（Standards for Reporting of Diagnostic Accuracy，STARD）中的各项条目。

结果：

本研究共纳入283例TURBT术后患者，其中136例为尿路上皮癌，147例为良性病变。136例尿路上皮癌中，根据病理学亚型分组，79（58.09%）例为浸润性尿路上皮癌，57（41.91%）例为非浸润性尿路上皮癌。根据恶性程度分组，112（82.35%）例为高级别尿路上皮癌，24（17.65%）例为低级别尿路上皮癌。以组织病理学诊断结果为金标准，136例尿路上皮癌中FISH、脱落细胞学、联合检测的准确率分别为79.51%、72.08%、77.39%，灵敏度分别为72.06%、58.82%、78.68%，特异度分别为86.39%、84.35%、76.19%。FISH、联合检测的曲线下面积（area under the curve，AUC）差异无统计学意义，但均高于脱落细胞学（0.792

结论：

尿路上皮癌中，尤其是浸润性和高级别尿路上皮癌，FISH的诊断效能优于脱落细胞学;FISH单独检测的准确率、灵敏度与联合检测相当，且特异性高于联合检测。在非浸润性或低级别尿路上皮癌中，3种检测方法的诊断效能均较低。

Abstract

Background and purpose:

Urothelial carcinoma (UC) is a prevalent malignant tumor of the urinary system

and early diagnosis is crucial for improving patient prognosis. This study evaluated the diagnostic efficacy of fluorescence in situ hybridization (FISH)

urine cytology and their combination for UC

as well as for its different subtypes.

Methods:

This study included patients who underwent transurethral resection of bladder tumor (TURBT) from January 2022 to December 2023 and approved by Ethics Commetce of Fudan Univesity Shanghai Cancer Center

No.: 050432-4-2307E) that met the inclusion and exclusion criteria. We collected TURBT pathological results and pre-procedure FISH and cytology results. Diagnostic accuracy

sensitivity and specificity of FISH

cytology an

d their combination were analyzed and compared for urothelial carcinoma. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist and Standards for Reporting of Diagnostic Accuracy (STARD) were followed for this study.

Results:

A total of 283 patients were enrolled in this study

136 were diagnosed with UC

and 147 were not. Of the 136 UC cases

79 (58.09%) were invasive and 57 (41.91%) were non-invasive. In terms of malignancy grade

112 (82.35%) were high-grade UC and 24 (17.65%) were low-grade UC. Using histopathology as the gold standard

the accuracy of FISH

cytology and their combination in diagnosing UC was 79.51%

72.08% and 77.39%

respectively; sensitivity was 72.06%

58.82% and 78.68%

respectively; specificity was 86.39%

84.35% and 76.19%

respectively. The area under the curve (AUC) for FISH and the combination was similar but higher than that for cytology (0.792

0.716

=0.006; 0.774

0.716

=0.004); the Net Reclassification Improvement (NRI) for FISH compared to cytology was 15.28% (

=0.006). In the 79 cases of invasive UC

FISH had higher accuracy than cytology (86.28%

78.32%

=0.011). The sensitivity of FISH and the combination was higher than that of cytology (86.08%

67.09%

=0.004; 91.14%

67.09%

0.001)

and the AUC values were also higher (0.808

0.713

=0.004; 0.784

0.713

=0.007). The NRI for FISH compared to cytology was 21.03% (

=0.003). In the 57 cases of non-invasive UC

the AUC values for all three methods were low (AUC

0.700). Among the 112 cases of high-grade UC

FISH had higher accuracy (84.94%

76.45%

=0.005)

and the combination had higher sensitivity (89.29%

66.07%

0.001) compared to cytology. The AUC values for FISH and the combination were also superior to that for cytology (0.847

0.752

=0.002; 0.827

0.752

=0.001). The NRI for FISH compared to cytology was 19.01% (

=0.003). In the 24 cases of low-grade UC

the AUC values for all three methods were low (AUC

0.600).

Conclusion:

For UC

particularly invasive and high-grade subtypes

FISH shows superior diagnostic efficacy compared to cytology. FISH alone offers accuracy and sensitivity comparable to the combination test

with higher specificity. In cases of non-invasive or low-grade UC

however

all three diagnostic methods demonstrate relatively low efficacy.
