A Comparative Study of the Paris System and Common Reporting System for Urine Cytology With Cyto-Histology Correlation: A Study of 829 Urine Cytology Specimens.
Background: The Paris System (TPS) diligently detects high-grade urothelial carcinoma (HGUC) and creates a uniform, standardized, reproducible reporting system for urine cytology. However, many centres might still use a common reporting system (CRS). The study aims to compare TPS and CRS for urine cytology with histology correlation.
Method: It was a cross-sectional study done from July 2016 to December 2022.
Results: The study included 829 urine cytology samples (96% voided urine) from 478 patients. Histology correlation was available for 138 (16.6%) samples of 115 patients. The frequency of NHGUC, AUC, HGUC and SHGUC was 40.6%, 17.4%, 12.2% and 5.5%, respectively, in TPS. In contrast, in CRS, the frequency of NM, AUS, SM and PM was 69.2%, 13.3%, 4.5% and 13.0%, respectively. TPS and CRS had 64% agreement overall with the kappa test (κ-value 0.479, moderate strength). The agreement between TPS and CRS was 39.8% for NHGUC, 10.97% for AUC and 10.85% for HGUC. After combining a few TPS categories, the agreement increased to 87.7% (κ-value 0.7640, good strength). Histological concordance for AUC, HGUC and NHGUC was 75%, 31.8% and 31.3% in TPS, and it was 50% and 33.3% for AUS and PM, respectively, in CRS. The sensitivity and specificity of TPS and CRS against histology were 37.5% vs. 26.0%, p = 0.0005 and 76.5% vs. 85.3%, p = 0.0083, respectively.
Conclusion: TPS and CRS have moderate strength of agreement for urine cytology. TPS was more sensitive than CRS. It may be easy for institutes to transition to a newer TPS system if they still use a CRS.
期刊介绍：
Diagnostic Cytopathology is intended to provide a forum for the exchange of information in the field of cytopathology, with special emphasis on the practical, clinical aspects of the discipline. The editors invite original scientific articles, as well as special review articles, feature articles, and letters to the editor, from laboratory professionals engaged in the practice of cytopathology. Manuscripts are accepted for publication on the basis of scientific merit, practical significance, and suitability for publication in a journal dedicated to this discipline. Original articles can be considered only with the understanding that they have never been published before and that they have not been submitted for simultaneous review to another publication.
