Cancer Stem Cells-Role in Oral Squamous Carcinoma - A Review of Literature

Abstract

The cancer stem cells (CSC) are responsible for the growth of cancerous tumours. The renewal of cancer stem cells is considered synonymous with that of normal cells. The cancer cells are considered a progeny of specific and designated stem cells. The identification of these cancer stem cells has proven to be more difficult than anticipated due to the specific niches they are present in, within the tumour.  Oral squamous carcinoma is the Sixth most common cancer constituting up to 2–4% of all malignancies worldwide and with poor prognosis. Tumour size and extent of lymph node metastasis are the most important predictors. The CSC works on the mechanism of bulk tumour cell formation and treatment resistance. But there are increased studies under this topic as it has been found that specifically targeting these cells can curb cancer. This review compiles information about the role of CSC in oral squamous cell carcinomas, the applications of CSC, and their use in the development of novel treatment options for oral cancer.
