Age and Cervical Histology, the Most Important Factors to Predict Human Papilloma Virus Clearance

Abstract

Background & Objective: Cervical Cancer (CC) is a common cancer which is associated with HPV-infection. The aim of this study is to investigate the risk factors which affects HPV-clearance.Materials & Methods: This study was carried out on women with high risk HPV infection. All the patients underwent pap smears and cervical biopsy. Demographic data, marital status, vaccination history and consumption of tobacco, alcohol, opium and oral contraceptive pills were asked through a questionnaire. Results: The results showed that in one year follow-up, 142 (67.1%) patients showed HPV clearance. The HPV clearance decreased by increasing age (P=0.028) or higher CIN grades (P=0.017). In case of parity, there was no significant difference in univariate analysis (P=0.147), but it was significant in multiple logistic regression analysis (95% CI: 0.413-0.941, OR=0624, P= 0.024).Conclusion: It seems that age and cervical histology at the start of HPV infection are the most important factors for HPV clearance.
