Probabilité diagnostique d’une lésion de haut grade chez les patientes ASCUS HPV positif en fonction du typage HPV

Abstract

ObjectivesThe aim of our study was to assess the proportion of high-grade histological lesions, according to HPV type, in patients referred for colposcopy involving a positive HPV-HR test and ASC-US cytology. MethodsThis is a retrospective descriptive study of asymptomatic patients aged 25 to 65 with a positive HPV-HR test and ASC-US cytology. Data were collected at the Nord Franche-Comté Hospital from September 2019 to February 2022. The primary outcome was the proportion of high-grade histological lesions in patients with ASC-US cytology combined to HPV 16 or 18 (associated or not with other HPV type), compared with HPV no 16 no 18. ResultsAmong the 298 patients included, 67% were HPV no 16 no 18, 22% HPV 16 associated or not with others and 11% HPV 18 associated or not with others. We found significantly fewer high-grade lesions in patients with ASC-US cytology and HPV no 16 no 18 than in patients with HPV 16 or 18 (8.5% versus 22.7%, P<0.01). In patients presenting an ASC-US cytology with HPV no 16, no 18: 53% of the biopsies found no histological lesion compared with 30% for the other HPVs (P<0.01). ConclusionsWe have highlighted the reality of colposcopists: a high ratio of normal coloscopy associated with normal or low-grade biopsies, in patients with a positive HPV-HR test no 16, no 18 and ASC-US cytology.
