Radiotherapy for carcinoma of the nasal cavity.

Twenty-five patients with primary epithelial carcinoma of the nasal cavity without nodal or distant metastases were treated by irradiation between 1967 and 1978. Small field, beam-directed techniques delivered 6,000 to 7,000 rads with conventional fractionation. Control of the primary tumor was achieved in 21 (84%) patients after irradiation. All five treatment failures (one infield only, three infield recurrence with lymph node metastases, and one regional cervical node metastasis) were evident within six months; all five patients died of cancer. The adjusted actuarial survival rate at three years was 76%. Failure in the untreated neck was only 5% when the primary carcinoma was controlled and 16% overall. The literature has been reviewed with attention to tumor control rates and survival.
