Dilemmas in Grading Epidermoid Carcinoma

چکیده
Oral squamous cell carcinoma (OSCC) can be preceded by the appearance of lesions which have the potential either to develop into cancer or signal the development of cancer in the oral cavity. Oral squamous cell carcinoma is the 8th most common cancer worldwide and found particularly in low income communities and mainly a problem of older men, 90% being in the 45-year-age group. Histologic grading has been used as a prognostic factor and for clinical evaluation of OSCC for the past several decades. At the same time, the prognostic value of different grading classifi cation remains controversial. So, in this article, we have reviewed the different grading system of oral squamous cell carcinoma and their prognostic value.
