چکیده انگلیسی:
Objective: Current guidelines suggest annual co-test follow-up in non-16/18 high-risk HPV positive patients without abnormal cytologic findings. Considering the relatively high false-negative rates of cervical cytology, a follow-up period of one year might constitute an additional risk for development of cervical malignancies in these patients. The current study aims to evaluate colposcopic biopsy results of cytologically normal patients detected to carry high risk HPV by screening tests. Materials and Methods: A total of 160 patients with normal cervical cytology and high-risk HPV subtypes who underwent colposcopic examination were included in the study. Patients were divided into two groups according to their HPV results: HPV 16-18 and other types (non-16/18 high-risk subtypes). ECC, cervical biopsy, LEEP/ conization results were analyzed for both groups. Histopathological results of the groups were compared in terms of ≤LSIL, HSIL and cervical cancer rates. Results: Cervical biopsy results in the “16-18” group were assessed as HSIL in 40 (48.2%) patients, LSIL in 6 patients (7.2%) and normal in 37 (44.6%) patients. ECC results revealed HSIL in 9 (10.8%) patients and LSIL in 1 (1.2%) patient. Nineteen out of 42 patients who underwent LEEP/conization had HSIL (surgical margin positivity was reported in 4 cases), while 3 patients had LSIL. None of the cases had cervical carcinoma. Conclusion: The present study detected that 15.6% of women infected with non-16/18 high-risk HPV subgroups developed ≥HSIL lesions. Although this rate seems lower than HPV 16-18 group, it is still too high to be overlooked. In conclusion, we suggest further clinical trials with larger number of patients to be conducted on this topic.
