[Adenoid cystic carcinoma of the maxillary sinuses].
OBJECTIVE
To investigate characteristic clinical features and outcomes for patients with adenoid cystic carcinoma of the maxillary sinuses (ACC).


METHODS
Thirteen patients with ACC were treated with a combination of surgery and radiation. Prognostic factors were retrospectively analyzed.


RESULTS
The most frequent cause of failure was local recurrence at the primary site. There was no neck node failure, 1 patient experienced distant metastases after the treatment. The overall disease-free survival rate at 5 years and 10 years were 72.5% and 54.4%, respectively.


CONCLUSIONS
The symptoms of the ACC occurred in the maxillary sinuses are not specific. The early diagnoses are usually difficult. Surgeries combined with postoperative radiation are recommended for optimal local control and survival. The prognostic factors include the clinic stages of the tumor and the resection margins.
