Objective: The aim of this study was to determine the frequency and genotype distribution of single and multiple human papillomavirus (HPV) infections in head and neck squamous cell carcinomas (HNSCCs) in a Mexican population and to assess their associations with smoking and drinking habits and clinicopathologic characteristics.
Study Design: A cross-sectional study was performed on a sample of patients diagnosed with HNSCCs. Tumor DNA was amplified using polymerase chain reaction with HPV consensus and multiplex primers.
