Intraoral adenoid cystic carcinoma: the role of postoperative radiotherapy in local control.

Fourteen cases of adenoid cystic carcinoma (ACC) of the intraoral salivary glands with positive surgical margins have been reviewed in order to determine the role of postoperative radiotherapy in local control. Since local control was obtained in all patients, postoperative radiotherapy seems an adequate treatment to deal with the problem of positive surgical margins at the microscopic level, in cases of intraoral ACC, making additional surgical treatment redundant.
