Clinical study of squamous cell carcinoma of maxillary sinus

Abstract

A retrospective study was conducted to evaluate the clinical outcomes of 11 patients with advanced squamous cell carcinoma of the maxillary sinus in our hospital between April 2012 and January 2016. Three patients had T3 disease, 4 patients had T4a and 4 had T4b. Seven patients underwent surgical resection. Six patients were treated with total maxillectomy and 1 with partial maxillectomy. Four patients who had microscopically involved resection margins and/or were extranodal extension-positive underwent postoperative chemoradiation therapy. The 5-year overall survival rates were 70％ in T3 and 50％ in T4a. Three patients with T4b underwent CCRT. Two were alive with no evidence of disease.
