Abstract

Background: Squamous cell carcinoma of the head and neck is the 6th most frequently occurring cancer worldwide, with over 400,000 cases projected annually. Multiple factors such as tobacco, alcohol, irradiation, virus, and chronic irritants are involved in the development of oral squamous cell carcinomas (OSCCs). The most important risk factors are chronic exposure to tobacco and alcohol. Although the evidence that implicates virus is increasing, particularly (human papillomavirus [HPV]), in the carcinogenesis process, the role of virus is not well established. Aim and Objective: This study is designed to assess the presence of HPV in potentially malignant and malignant lesions of the oral cavity as well as to correlate the presence of HPV with addictive habits and histopathological grading of the disease. Materials and Methods: Biopsy samples of OSCC and potentially malignant lesions were obtained and 3, 5 μm thickness sections were cut using a microtome. The sections were collected using a sterile brush and transferred to an Eppendorf tube. DNA extraction and polymerase chain reaction for the detection of HPV were done. Results and Conclusion: The association between histopathological grading and presence of HPV was assessed using Chi‑square test and the values thus obtained were found to be statistically significant. HPV was more predominantly seen in well‑differentiated carcinomas and moderately differentiated carcinomas as compared to poorly differentiated carcinomas.
