Abstract

Introduction: Cancer is one of the leading causes of death worldwide. Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity in which there is a poor prognosis. Viruses, including human papillomavirus (HPV) play an important role in the etiology of this cancer. Methods: This case–control study enrolled 100 individuals with diagnosed oral cancer in the case group and an equivalent number of 100 healthy individuals in the control group. Over the course of 1 year, samples were collected from Khalili Hospital in Shiraz, Iran. Tissue specimens were procured from diverse oral regions, with specimens from the healthy group exclusively sourced from the tonsillar area. Patient inclusion criteria involved manifestations like oral swelling, facial pain, tongue abnormalities, tongue paralysis, and tumors or swellings in the inner lip, gums, or chin. A questionnaire facilitated the collection of demographic data, covering variables such as age and gender. The subjects had a mean age of 53.66 ± 1.38 years, with a gender distribution of 70 individuals (34%) female and 130 (65%) males. Tissue specimens underwent molecular analysis using Nested-PCR to detect HPV presence. Results: Analysis unveiled HPV identification in two cases within the control group and 14 cases within the case group, revealing a statistically significant disparity (p value = 0.008) which may be correlated to incidence of OSCC within the case group. Further exploration disclosed a predilection for HPV localization in the tongue, followed by the laryngeal region. A significant association was established between the sampling site and HPV incidence (p = 0.004). Conclusion: This investigation unveiled a compelling connection between the site of sampling and HPV infection, a phenomenon pronounced particularly among individuals grappling with oral cancer. This underscores potential relationship between the site of sampling and HPV infection within the context of oral carcinoma. The findings of this study underscore HPV's role as a significant risk factor in the initiation of oral cancer in individuals. Nevertheless, it is important to acknowledge that additional factors, including age and gender, also contribute to this intricate process. © 2024 Japanese Stomatological Society.
