Assessing the analytical efficacy of TEX in diagnosing oral cancer using a systematic review approach.

The 5-year survival rates in OSCC depend on the stage at diagnosis. Patients have better survival and favourable outcomes if detected early, as compared to those diagnosed in advanced stages. Apart from biopsy and mucosal scraping examinations, exosomes from saliva and blood are emerging as an accessible source for diagnosis and providing additional information about the tumour's characteristics. Hence, the study of tumour-derived exosomal (TEX) biomarkers obtained from a liquid biopsy is emerging as a promising diagnostic tool. In this systematic review, our effort is to assess the role of TEX as a biomarker.
