Adenoid cystic carcinoma of the major salivary glands treated with surgery and radiation.
OBJECTIVE
To examine patient characteristics, pathologic features, and treatment outcomes of adenoid cystic carcinoma of the major salivary glands.


METHODS
Retrospective review of patients in an academic medical center.


METHODS
Review of medical records regarding demographics, extent of tumor, stage, histologic characteristics, and treatment outcomes of patients treated with surgery and postoperative radiation.


RESULTS
Of the 33 patients, 19 (58%) were male, and 14 (42%) were female. The average age of presentation was 49 (range 22-81) years. Of the 29 patients fully staged at the time of diagnosis, 7 (24%) presented at American Joint Committee on Cancer stage I, 9 (31%) at stage II, 4 (14%) at stage III, and 9 (31%) at stage IV. The cribriform histologic subtype was predominant (64%). The majority originated in the parotid gland (21, 64%), with the remaining originating in either the submandibular gland (10, 30%) or the sublingual gland (2, 6%). Local control was 94% at 5 years and 73% at 10 years. Metastatic control was 82% at 5 years and 63% at 10 years. Four patients failed locally and nine failed distally. Overall survival was 85% at 5 years and 69% at 10 years, with a median of 12.9 years.


CONCLUSIONS
Surgical excision with postoperative radiation provides a long period of disease-free survival. Patients were more likely to fail with metastases than with local recurrence.
