Abstract
OBJECTIVES/HYPOTHESIS: Adenoid cystic carcinoma (ACC) occurs infrequently in the larynx. Consequently, no large samples describing its clinical behavior are available in the literature. Our objective was to use a nationally representative population-based resource to evaluate clinical behavior, patient demographics, and outcomes among patients diagnosed with laryngeal ACC (LACC). STUDY DESIGN: Retrospective database analysis. METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results database was analyzed for patients diagnosed with LACC between 1973 and 2011. Patient demographics, incidence, treatment, and survival between LACC and other laryngeal malignancies were compared. RESULTS: Of 69 LACC patients, 63.8% were female, 78.2% Caucasian, and the median age was 54 years. LACC patients were much more likely to have subglottic lesions (44.9%) than individuals with other malignancies (1.6%). The incidence of LACC was 0.005/100,000 individuals. The majority of patients with LACC harbored T4 lesions at initial diagnosis, although 87.9% had N0 disease, and only 6.1% had distant metastasis at diagnosis. Disease-specific survival (DSS) was greater at 1 year for LACC compared to other laryngeal malignancies, but not at 5 or 10 years. Five-year DSS was greater for LACC patients who underwent surgery versus those who did not undergo surgery. CONCLUSIONS: This analysis notes that LACC has a low incidence with no significant change in incidence over the study period. Compared to other laryngeal malignancies, LACC has a female preponderance, is much more common in the subglottis, presents at a younger age, and more often presents with T4 disease. Surgery was noted to confer a survival advantage in LACC. LEVEL OF EVIDENCE: 4.
