Frequency of HR-HPV Types in Patients with High Grade Cervical Intraepithelial Neoplasia (CIN)

Background & Objective: Cervical cancer is the second most common cancer and the fourth leading cause of death in women. Among the risk factors for cervical cancer, human papillomavirus (HPV) is the most important one. Materials & Methods: In this cross-sectional and retrospective study conducted from ۲۰۱۶ to ۲۰۲۰, ۲۶۱ women with cervical intra-epithelial neoplasia (CIN) grade two and three referred to one of the gynecological oncology clinics of Shahid Beheshti University of Medical Sciences, who were eligible to enter the study and were evaluated by the research unit of the relevant university after receiving an ethics code. During the study, patients whose cervical cancer was confirmed by colposcopic diagnostic method, HPV screening was performed by COBAS method and lesions were sampled to determine the type of HPV. Results: Evaluation of the frequency distribution of colposcopic results compared to HPV, indicated that HPV-۱۶ is the most common type of HPV in high grade CIN lesions. After HPV-۱۶, other types of HPV are next in terms of frequency indicating the importance of other types of HPV. HPV-۱۸ was also observed in people with CIN. Conclusion: Performing a similar study with a larger number of samples at the national level is suggested. If the results of a larger study are consistent with this study, it would be for the best to highlight the role of other types of HPV in cervical cancer screening in women.
