Abstract
The objective of this study was to report outcomes for 19 consecutive patients with SMARCB1 (INI-1)-deficient sinonasal carcinoma. Patients were treated from 2014 to 2021 and followed for a median of 22.3 months. The median overall survival (OS) and disease-free survival (DFS) were 31.8 and 9.9 months, respectively. Patients with nasal cavity or maxillary sinus tumors had 84% better disease-specific survival (DSS) (hazard ratio [HR], 0.136; 95% confidence interval [CI], 0.028-0.66; p =.005) and 71% better DFS (HR, 0.29; 95% CI, 0.097-0.84; p =.041) than patients with other sinonasal sites. Patients who received induction chemotherapy were 76% less likely to die of disease (DSS HR, 0.241; 95% CI, 0.058-1.00; p =.047). In the largest single-institution study of SMARCB1-deficient sinonasal carcinoma to date, OS and DFS approached 3 years and 1 year, respectively, but were better for nasal cavity and maxillary sinus tumors. Patients may benefit from induction chemotherapy.
