Carcinomas of the nasal cavity.

Abstract:

Between 1969 and 1985, 45 patients with carcinomas of the nasal cavity proper received curative treatment. Thirty patients had squamous cell carcinoma, one had undifferentiated carcinoma, 9 had adenocarcinoma, and 5 had adenoid cystic carcinoma. Eighteen patients were treated with definitive radiotherapy (interstitial brachytherapy in 5 and external beam therapy in 13 patients), and 27 received surgery and radiotherapy. The median length of follow-up was 11 years (range: 2.8-16.8 years). Thirty-six patients had no evidence of disease at the last follow-up visit. All 14 patients with carcinoma of the nasal septum had the disease controlled. Nine of 31 patients with lesions of the lateral wall and floor died of the disease, 5 of uncontrolled local disease, 2 of distant metastases, and 2 of both. The disease-specific survival rates at 5 and 10 years were 83 and 80%, respectively, and the corresponding overall survival rates were 75 and 60%, respectively. Blindness occurred in 4 patients, 2 due to orbital exenteration and 2 to radiation injury to the cornea and optic pathway. Other infrequent side effects were bone necrosis, dental decay, nasal stenosis, and septal perforation. This study indicated that the prognosis of patients with nasal cavity carcinoma was better than that of patients with maxillary sinus cancer treated during the same era. In addition, the study showed that carcinomas of the nasal septum were smaller than those of lateral wall and floor at diagnosis, so that excellent control could be achieved by definitive radiotherapy; when accessible, interstitial brachytherapy might be the treatment of choice in such patients.
