Background: Minimal information has been reported on the effect of distant and nodal metastases at the time of diagnosis on survival in patients with sinonasal adenocarcinoma (SNAC). Methods: The Surveillance, Epidemiology, and End Results database was utilized to compare overall survival (OS) and disease-specific survival (DSS). Results: Of the 325 patients with SNAC identified, 5-year and 10-year OS for all included patients was 64% and 58%, respectively. On multivariate analysis, the presence of distant metastases (P <.0001), maxillary and frontal sinus primary tumors (P =.0042, P =.0006), and increasing age (P =.007) were risk factors for worsened DSS. The presence of regional spread to multiple cervical nodal basins (OS RR 3.26, P =.002; DSS RR 2.51, P =.013) and a single nodal basin (DSS RR 2.19, P =.046) was associated with worsened survival compared to no regional spread. Conclusion: Survival in SNAC was significantly worsened with increasing age, tumor site of origin, and distant metastatic disease.
