Carcinoma of the nasal cavity and paranasal sinuses.

摘要

OBJECTIVES/HYPOTHESIS: To determine the outcomes after radiotherapy (RT) alone or combined with surgery at the University of Florida for patients with carcinomas of the nasal cavity and paranasal sinuses. METHODS: Between November 1964 and June 2005, 109 patients were treated with curative intent. Patients with maxillary sinus carcinomas were excluded. Fifty-six patients were treated with definitive RT, and 53 patients received surgery and preoperative (eight patients) or postoperative (45 patients) RT. Median follow-up was 4.3 years (range, 0.2-35.9 years). Median follow-up on living patients was 9.4 years (range, 2.0-35.9 years). RESULTS: The 5-year local control rates were: T1-T3, 82%; T4, 50%; and overall, 63%. Local control at 5 years was 43% after definitive RT versus 84% after surgery and adjuvant RT (P < .0001). Multivariate analysis of local control revealed that both overall stage and treatment group (definitive RT versus surgery and adjuvant RT) significantly impacted this endpoint. Cause-specific survival rates were: stages I to III, 81%; stage IV, 54%; and overall, 62%. Multivariate analysis revealed that T-stage, N-stage, and treatment group significantly influenced this endpoint. Thirty-one (20%) of 109 patients sustained severe complications; 17 of 56 patients (16%) after definitive RT and 14 of 53 patients (25%) after surgery and adjuvant RT. CONCLUSIONS: The probability of local control and cause-specific survival is better after surgery and RT compared with definitive RT. There is a modest increase in the risk of complications after surgery and RT. Thus, the preferred treatment is surgery combined with preoperative or postoperative RT.
