Cervical intraepithelial neoplasia in non-16/18 high-risk human papilloma virus positive/cytology negative women: An alternative approach in poor resource areas
Objective: Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative case...

| Summary: | Objective: Because the specific prevalence and carcinogenesis of non-16/18 high-risk (hr) Human Papillomavirus (HPV) is not fully understood, we designed a study with aim of evaluating the risk of high-grade cervical intraepithelial neoplasia (CIN) in non-16/18 hr-HPV positive/cytology negative cases and assessing the distribution of non-16/18 hr-HPV subtypes. Materials and methods: This cross-sectional study was conducted on 138 non-16/18 hr-HPV positive/cytology negative women, who were referred to the gynecologic oncology clinic of Yas hospital, affiliated with Tehran University of Medical Sciences, January 2021 to 2022. Results: Among the detected types, HPV 31 was the most frequent type. 63 cases underwent biopsy as indicated based on colposcopic examination with acetic acid 3% application among which 34 had normal results. In the remaining 29 cases, 25 had insignificant findings. CIN2 was reported in 2 cases, one with HPV 31, 45, 58, and the other with HPV 58. CIN3 was also detected in 2 cases, one with HPV 31 and the other with HPV 35, 45.The overall incidence of high-grade CIN was 2.8%. A statistically significant (P-value = 0.046) difference was detected between patients with high-grade CIN compared with the others regarding the Hookah usage. Conclusion: The risk of CIN among non-16/18 hr-HPV positive/cytology negative cases is noticeably low. Based on ASCCP guidelines return testing at 1 year without immediate colposcopy seems sufficient; however, because of many reasons doing immediate colposcopy rather than 1-year follow-up may be a more accessible approach in resource poor, low-income countries such as ours. |
