Abstract：
Objectives: To evaluate the clinical value of the Paris system for reporting urinary cytology (TPS) in the diagnosis of urothelial carcinoma (UC). Methods: A total of 1 744 cytological diagnostic records (from 751 cases) were collected retrospectively. All specimens were voided urines and histopathology as the gold standard. The sensitivity and specificity of urinary cytological diagnosis of UC and risk of high grade malignant (ROHM) in each diagnostic category were compared. Results: There were 360 cases with histopathology. The percentage of negative for high-grade urothelial carcinoma (NHGUC) was 30.1% (226/751), atypical urothelial cells (AUC) was 29.8% (224/751), suspicious for high-grade urothelial carcinoma (SHGUC) was 16.8% (126/751), high grade urothelial carcinoma (HGUC) was 21.2% (159/751), and non-urothelial malignancy (NUM) was 2.1% (16/751). The histpathologic ROHM corresponding to each cytological diagnosis category were 27.3% for NHGUC, 32.7% for AUC, 74.7% for SHGUC, 96.6% for HGUC and 100.0% for NUM, respectively. ROHM of SHGUC was significantly higher than that of AUC group, and the difference between the two groups was statistically significant (P＜0.001). ROHM of HGUC group was significantly higher than that of SHGUC group, and the difference was statistically significant (P＜0.001). With SHGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 76.7% (165/215) and 85.7% (18/21), and with HGUC as the cut-off value, the sensitivity and specificity of cytological diagnosis of HGUC were 53.0% (114/215) and 100.0% (21/21), respectively. Conclusions: Urine cytology has high sensitivity and specificity in the diagnosis of HGUC. The malignant risk of TPS varies with different diagnosis category. The high malignant risk population in cancer hospital leads to the relatively high malignant proportion and ROHM in each diagnosis category. Urinary cytology TPS reporting system is helpful to clinical management and has good clinical application value.
目的： 探讨尿液细胞学巴黎报告系统（TPS）在临床应用中的实际意义。 方法： 回顾性连续收集2020年1月至2022年6月中国医学科学院肿瘤医院1 744份自然排空尿标本（751个尿液标本）细胞学诊断资料，以组织病理诊断为金标准，对比尿液细胞学诊断尿路上皮癌的灵敏度、特异度及每个诊断分类的高级别恶性风险。 结果： 360例患者有组织病理诊断结果，细胞学诊断分类占比分别为未见高级别尿路上皮癌 30.1%（226/751）、非典型尿路上皮细胞 29.8%（224/751）、可疑高级别尿路上皮癌 16.8%（126/751）、高级别尿路上皮癌 21.2%（159/751）、非尿路上皮恶性肿瘤 2.1%（16/751）。细胞学各个诊断级别所对应的组织病理相关高级别恶性风险分别为27.3%（未见高级别尿路上皮癌）、32.7%（非典型尿路上皮细胞）、74.7%（可疑高级别尿路上皮癌）、96.6%（高级别尿路上皮癌）、100.0%（非尿路上皮恶性肿瘤）。可疑高级别尿路上皮癌高级别恶性风险高于非典型尿路上皮细胞（P＜0.001），高级别尿路上皮癌高级别恶性风险高于可疑高级别尿路上皮癌（P＜0.001）。以可疑高级别尿路上皮癌为界值，细胞学诊断高级别尿路上皮癌的灵敏度和特异度分别为76.7%（165/215）和85.7%（18/21）；以高级别尿路上皮癌为界值，细胞学诊断高级别尿路上皮癌的灵敏度和特异度分别为53.0%（114/215）和100.0%（21/21）。 结论： 尿液细胞学诊断高级别尿路上皮癌有较高的灵敏度和特异度；TPS不同诊断级别的恶性风险不同，肿瘤专科医院的高恶性风险人群导致了各个诊断级别均有相对高的恶性占比及高级别恶性风险；TPS有助于临床管理，有较好的临床应用价值。.
