Head and neck cancer is the most commonly diagnosed cancer worldwide, with 90%–95% of the cases reported to be squamous cell carcinoma. The disease is one of the most mystifying, commonly misdiagnosed and poorly understood entities because the lesion is often situated in a relatively inert space where only air and mucus are in transit. Head and neck squamous cell carcinoma (HNSCC) can be silent for a long time without any primary symptoms. In Northeast India, HNSCC is most familiar in the states of Assam, Manipur, Mizoram, Tripura, and Nagaland with an incidence of 54.48%, which acquires 30%–40% cancers at all sites and is the sixth most common cause of death in males and seventh in females.

Our current research is focused on circulating cell-free nucleic acid.The clinical viewpoint of cell-free DNA (cfDNA) has sparked the interest of scientists as it opens up a new possibility for non-invasive analysis of tumor-derived genetic materials such as circulating tumor cells (CTCs), cfDNA, cell-free mitochondrial DNA (cfmtDNA), circulating RNA, or microRNAs. The idea of a “liquid biopsy” analysis may provide a means for non-invasive, real-time monitoring, with potential applications of prognosis, response to therapy, and emergence of treatment resistance.

The overall goal of this proposal is to detect the presence and fractions of circulating cell-free tumour DNA (ccftDNA) in plasma of cancer patients and determine the feasibility of a deep sequencing-based [exome] approach to cancer detection.
