ABSTRACT
The association of human papillomavirus (HPV) in laryngeal malignancies is largely known. This study evaluated the association between HPV and benign laryngeal lesions and also the role of smoking and alcohol consumption in increasing the prevalence of HPV in such benign lesions. Seventy-eight specimens of benign laryngeal lesions including 26 polyps, 26 dysplasia, and 26 other lesions such as nodules and cysts were enrolled in this study. Polymerase chain reaction (PCR) technique was used to detect HPV DNA in the tissues. The role of smoking and alcohol consumption in the prevalence of HPV was also evaluated through appropriate statistical tests. This study showed that the prevalence of HPV in benign laryngeal lesions was not statistically significant. The Cohen's effect size for comparing polyps vs. other lesions was nearly 0.7, indicating that HPV prevalence in laryngeal polyps may be clinically meaningful. Another finding in our study is the role of smoking in increasing the HPV prevalence in laryngeal polyps (P = 0.034). In benign laryngeal polyps, HPV prevalence may be clinically important. Smoking acts as a co-factor to induce HPV infection in laryngeal polyps in our study.
