Abstract

Background: Acinic cell carcinoma (AciCC) is an uncommon malignant-epithelial salivary gland cancer. In very rare cases, this tumor may arise from sinonasal subsites, with only 19 cases described in the English-language literature. Methods: We performed a retrospective analysis of 18 cases of AciCC, obtained from searching the Surveillance, Epidemiology, and End Results (SEER) database between 1973 and 2009. Results: Patient demographics, including age, gender, and race, were similar to AciCC cases found in more common locations. However, all patients had low-grade tumors without regional or distant metastases. Comparing these patients to a stage, grade, and treatment-matched cohort of parotid AciCC, we found a lower 10-year overall survival (52.3%) with no significant difference in disease-specific survival (88.9%). Our meta-analysis of survival from cases in the literature estimated 10-year recurrence-free survival at 92.9%. Conclusion: To our knowledge, this is the largest cohort of patients with AciCC reported in the English-language literature. Our results suggest that patients with sinonasal AciCC have excellent disease-specific survival, comparable to matched patients with AciCC in more common salivary gland subsites.
