Clinicopathological study of SIN at the surgical margin after partial glossectomy for primary SCC

Abstract

Clinical management and histopatholocial conservations of epithelial dysplasia at the surgical margin at the time or after glossectomy for oral mucosal squamous cell carcinoma has been retrospectively discussed. The subjects were 34 patients with T1/T2 primary squamous cell carcinoma of the tongue who had undergone resection without pre-operative treatment in our hospital, for 10 years, between January 1995 and June 2006. Histopathological evaluations and prognosis were assessed according to squamous intraepithelial neoplasia (SIN) classification designed by the Japan Society of Oral Tumours Committee and the Working Group for Guideline of Tongue Cancer Treatment.
