Adenoid cystic carcinoma of the palate

We reviewed the clinical records of 41 patients who received definitive treatment for adenoid cystic carcinoma arising from the palate. Tumors were divided into three categories depending on local extension and pattern of growth. Surgery, either alone or in combination with post-operative radiation therapy, yielded satisfactory local regional control of the cancer. Patients who had adenoid cystic carcinoma with diffuse microscopic spread into adjacent tissues had the highest propensity for the development of distant metastases.
