A Clinical Study of Maxillary Sinus Squamous Cell Carcinoma

We report a retrospective study of 26 patients with maxillary sinus squamous cell carcinoma who were treated at the Sapporo Medical University between January 2002 and December 2008. The 5-year local control rate was 85.7% in patients with stage T2-3 disease and 61.0% in patients with stage T4a disease. The overall 5-year survival rate was 71.3% and the 5-year disease-specific survival rate was 79.9%. The 5-year disease-specific survival rate was 100% in patients with T2-3 disease and 44.4% in patients with T4 disease. The 5-year disease-specific survival rate was 76.3% in patients with N0 disease and 87.5% in patients with N+ disease. Five patients died of stage T4a disease. Two died of uncontrolled tumors at the primary site and 3 patients died of lung metastasis. We should consider another approach for the treatment of patients with advanced maxillary sinus carcinoma in the future.
