Background and aimHPV (Human Papilloma Virus) infection represents a necessary condition for cervical carcinogenesis. The purpose of this study was to evaluate the efficiency of HPV testing using an immunohistochemical staining kit with implications upon both diagnosis and treatment of cervical intraepithelial neoplasia (CIN).MethodsSeventy-nine patients and eighty-six controls were enrolled in the study. Each patient had completed a physical examination, gynecological examination with cervical sampling using a liquid-based cytology system and also colposcopy. The cervical samples were analyzed according to Bethesda terminology and HPV-HR immunohistochemical staining was performed. In all the patients with high-grade lesion a surgical excision procedure was performed followed by pathological examination of the specimen. The collected data were analyzed using statistical software.ResultsThe colposcopic examination has detected acetowhite modifications of the cervical epithelium in 47% of patients with ASC-US (Atypical squamous cells of undetermined significance) in 71% of patients with LSIL (Low grade squamous intraepithelial lesion) and in 100% of patients with HSIL ( High grade squamous intraepithelial lesion). The biopsy confirmed the diagnosis of LSIL in 27% of biopsy specimens in patients with ASC-US and in 79.99% of patients with LSIL respectively. In all patients with HSIL the diagnosis was CIN II or higher. The percentage of HPV-HR (Human Papilloma Virus – High Risk) positivity porportionaly increased with the severity of cytological diagnosis: 30% in ASC-US, 42.86% in LSIL and 75% in HSIL patients. The sensitivity of detection of HPV-HR was 50% with CI 95% [17.45;82.55] for ASC-US, 77.77% with CI 95% [51.91;92.62] for LSIL and 81.81% with CI 95% [58.99;94.00] for HSIL.ConclusionHPV testing can be an important screening tool for cervical dysplasia. The HPV testing targeting high risk types is indicated for ASC-US and LSIL triage. The present work sustains the idea of introducing HPV testing as a primary screening tool for cervical cancer.
