Practical application of modified ASCCP 2019 algorithms in the diagnosis and early detection of cervical pathology

Abstract

Objectives: We assessed the risk for the high-grade precancerous CIN 2 (+) in women with HSIL and ASC-H depending on HPV status. Material and methods: A retrospective analysis of results of cervical cancer screening following the current ASCCP recommendations by co-testing (LBC and molecular HPV DNA HR) performed between 2018 and 2022 in the Laboratory of Cervical Pathology, Obstetrics and Gynecology Hospital of Poznan University of Medical Sciences. Patient ages ranged from 22 to 72 years. Results: The analysis of abnormal results of liquid-based cytology revealed the following: 1 suspicion of cervical carcinoma, 49 HSIL, 97 ASC-H, 95 LSIL, 92 ASCUS, and 4 AGC cases. Histopathological verification of the biopsy samples revealed a total of 288 abnormal results. CIN 2 (+) lesions were found in 127 women. ASC-H was the most common abnormal cytologic finding. Of the 338 molecular test results for HPV DNA HR, 85% were confirmed positive. A positive molecular signal confirming the presence of human papillomavirus on PAP smear was not homonymous with simultaneous histopathological diagnosis of cervical pathology. Conclusions: There is a high risk for CIN 2 (+) in patients with HSIL and HPV 16 (+) and/or HPV DNA HR (+), as well as ASC-H and HPV 16 (+). HSIL is rarely observed in women with HPV 16 (–). The risk for CIN 2 (+) in women with ASC-H and HPV (–) is low.
