Abstract: Background: Determining the distribution of high-risk human papillomavirus (HR-HPV) types in histologic low-(LSIL) and high-grade (HSIL/CIN2+) squamous intraepithelial lesions through a diagnostic process in a cervical cancer prevention provides one of the key etiological factors behind further progression and persistence. Incorporating novel high-grade cervical lesion biomarkers such as p16/Ki67 dual staining (DS) alongside HPV typing has become important in detecting cervical precancers. Methods: Among 28,525 screening tests and 602 histology results, 559 cases with HR-HPV and histology results obtained from colposcopic biopsy were retrospectively analyzed, together with DS status. The χ2 test with Bonferroni correction evaluated the differences in HR-HPV type prevalence and DS positivity across three histologic study groups. Results: A statistically significant difference in the prevalence of HPV 16 was observed between negative and HSIL/CIN2+ (p = 0.00027) groups, as well as between the LSIL/CIN1 and HSIL/CIN2+ groups (p = 0.00041). However, no significant difference was found between the negative and LSIL/CIN1 groups. Similarly, the DS positivity difference was significant between the negative and HSIL/CIN2+ (p < 0.0001) and between the LSIL/CIN1 and HSIL/CIN2+ groups (p < 0.0001), but there was no significant difference between the negative and LSIL/CIN1 groups. Conclusions: The study highlights the heterogeneous nature of HPV-related cervical pathologies, and the distinct risks associated with different cervical lesion grades, emphasizing the importance of HR-HPV type distribution and DS status.
