Squamous cell carcinoma of the buccal mucosa

The purpose of this study was to establish treatment criteria for patients with early-stage squamous cell carcinoma of the buccal mucosa. Thirty-one patients were analyzed in a retrospective fashion. Distribution of patients according to tumor stage was relatively even. Within 5 years recurrent disease developed in nearly 80% of evaluable patients. There was a 100% overall incidence of local disease recurrence for patients with stage I and II tumors treated with wide local excision alone and followed up for more than 2 years. On the basis of these data, we conclude that wide local excision for early-stage buccal carcinoma is associated with a high local failure rate. Possible causes for failure and alternative treatment approaches are discussed.
