Role of Human Papilloma Virus in the Aetiology of Sinonasal Cancers.

Sino nasal carcinogenesis is attributed to numerous factors, namely tobacco, alcohol and snuff as the most common. Human Papilloma virus (HPV) has been associated with aetiopathogenesis of malignancies in the upper aerodigestive tract (UADT). The prevalence of HPV in Sino-nasal malignancy (SNM) which is closely related to UADT in location is not known. Hence, this study aims to explore if there is any such association between HPV and Sino nasal malignancies. This study aims to explore the association between HPV and SNM. A prospective case control study using tumour tissue specimens from 40 Sinonasal carcinoma patients and benign nasal tissue specimens from 50 cancer-free controls were conducted. Histopathological analysis and DNA extraction (DNeasy® Tissue kit) and polymerase chain reaction for detection of HPV was done. Positive samples underwent sequencing to detect the HPV serotype and statistical correlation was performed using SPSS software. All 90 patients were tested for HPV and we found that none of the patients had any association with HPV. Sino-Nasal malignancy in the Indian Sub-continent may not be related to HPV primarily.
