Adenoid cystic carcinoma (ACC) is a salivary gland malignancy with unpredictable growth and poorly understood prognostic factors.A database search of patients treated at a single Institution was used to identify patients with histologically-confirmed ACC. Patient, tumor, and treatment characteristics were examined via review of medical records.Overall survival of 70 patients identified at 5, 10, and 15 years was 80.4%, 61.3%, and 29.4%, respectively. Disease recurrence was seen in 31.9%; of these, 72.7% developed distant metastasis. Older age, higher stage, skull base involvement, positive margins, and metastatic disease, but not local recurrence, predicted a worse overall survival. Higher stage and skull base disease were also associated with shorter disease-free survival. While lung metastasis was the most common, vertebral metastasis was associated with poorer survival.Disease stage, positive margins, skull base involvement, perineural invasion, time to recurrence, and location of metastasis, but not nodal involvement, could serve as poor prognostic factors in ACC.
