Abstract
PURPOSE: The primary aim of this study was to evaluate the diagnostic accuracy of colposcopy in identifying high-grade squamous intraepithelial lesion or worse (HSIL+) and the characteristic performance of colposcopic images with various severity levels of cervical lesions. METHODS: The medical records from 1828 women who underwent colposcopy at Affiliated Hospital of Tongji University from February 2016 to March 2019 were reviewed. Human papilloma virus (HPV) GenoArray test kit (HybriBio Ltd) and Thinprep cytologic test (TCT, Hologic, USA) were used to perform HPV genotyping and cytology. All colposcopic images were collected from the standard-of-care colposcope (Leisegang 3ML LED) and evaluated based on the 2011 International Federation of Cervical Pathology and Colposcopy (IFCPC) Colposcopy Standards. The linear by linear association, Pearson χ2 test, χ2 test, Kappa test, McNemar test and risk test were used to perform statistical analyses. RESULTS: The consistency between colposcopy and biopsy pathology was 59.35% with the moderate strength of kappa coefficient of 0.464. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of colposcopy and cytology for HSIL+ were 56.29%, 93.82%, 77.47%, 85.04% and 37.13%, 98.49%, 90.29%, 80.58%, respectively. The colposcopic features of HSIL+ were as follows: (1) thick or bulgy acetowhite epithelium with sharp border; (2) completely nonstained of Lugol's iodine; (3) type III/IV/V of gland openings; (4) punctation or atypical vessels. CONCLUSION: The data and findings herein provide the resource for evaluating the diagnostic value of colposcopy, and suggested that the accuracy of colposcopy is required to be further improved.
