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.
