Background: Long Interspersed Nuclear Elements-1 (LINEs-1) methylation from white blood cells (WBCs) DNA has been proposed as biomarker associated with different types of cancer. The aim of the present study was to investigate the degree of WBCs LINE-1 methylation, according to high-risk Human Papilloma Virus (hrHPV) status in a healthy population, and the association with high-grade Cervical Intraepithelial Neoplasia (CIN2+) in hrHPV positive women.
Methods: Women with abnormal cervical cells were enrolled and classified by histological diagnosis and hrHPV infection.
Objectives: Host factors, including genetic polymorphisms, may explain some of the individual differences in cervical cancer occurrence, and susceptibility information may be useful to address effective and specific preventive strategies for different countries. The purpose of the present study was to investigate the role of p53 codon 72, glutathione S-transferase class mu (GSTM1), glutathione S-transferase class theta (GSTT1), and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms on the risk for infection and/or of cervical intraepithelial lesions in women attending a colposcopy service in Catania, Sicily, with an already reported high prevalence of human papillomavirus.
Methods: To identify the association among individual genetic polymorphisms, human papillomavirus infection, and histological findings, a case-control study was designed.
Introduction: Human papillomavirus (HPV) infection has been strongly and consistently associated with cervical carcinoma and its cytologic precursors, such as squamous intraepithelial lesions. A cross-sectional survey was conducted with the aim of estimating the prevalence of cervical HPV infection in women attending a service of colposcopy in Catania, Eastern Sicily, Italy.
Methods: The prevalence of type-specific HPV was examined in women with negative colposcopic results and cervical intraepithelial neoplasia grades 1, 2, or 3, with the aim of providing some cross-sectional figures on the local epidemiology of HPV infection.
