Prognostic impact of human papillomavirus infection on cervical dysplasia, cancer, and patient survival in Saudi Arabia: A 10-year retrospective analysis

Abstract

BACKGROUND: Data on human papillomavirus (HPV) prevalence and survival rates among HPV-infected women are scarce in Saudi Arabia. OBJECTIVE: Assess the prevalence of HPV genotypes in cervical biopsy specimens and its effect on survival over a 10-year timeframe. DESIGN: Retrospective, cross-sectional. SETTINGS: Saudi referral hospital. PATIENTS AND METHODS: Cervical biopsy specimens were collected from women aged 23-95 years old who underwent HPV detection, HPV genotyping, p16INK4a expression measurement using immunohistochemistry. Kaplan-Meier plots were constructed to analyze overall survival rates. MAIN OUTCOME MEASURES: Survival rate of HPV-positive cervical cancer patients. SAMPLE SIZE: 315 cervical biopsy specimens. RESULTS: HPV was detected in 96 patients (30.4%): 37.3% had cervical cancer; 14.2% cervical intraepithelial neoplasia (CIN) III, 4.1% CIN II, and 17.0% CIN I. A significant association was found between HPV presence and cervical cancer (Χ2 =56.78; P
