Ninety-five of the 443 patients with squamous cell carcinoma of the head and neck region treated from 1972 to 1981 at Gunma Cancer Center had cervical node metestases. A clinical analysis of this group showed the following:1. The over all rate of cervical metastasis in this series was 21.4 per cent.2. The most common primary lesion was nasopharyngeal carcinoma (52.2 per cent had cervical node metestases).3. Of the 132 patients with carcinoma of the oral cavity, 25.7 per cent had cervical metastases, and of the 144 patients with laryngeal carcinoma, 15.3 per cent. However, none of the 64 patients with maxillary carcinoma had cervical lymph node metastases.4. The patients were classified according to the TNM system of UICC (1978). Three patients were T1, 20 were T2, 44 were T3, 28 were T4, 41 were N1, 5 were N2 and 49 were N3. The T3 and T4 groupe accounted for 75.7 per cent.5. The five-year survival rates were 23.5 per cent for those treated with neck dissection and 5.3 per cent for those who received radiotherapy only.6. The patients of the laryngeal carcinoma group had the highest three-year survival rate, 31.3%, and the hypopharyngeal carcinoma group, the lowest, 14.3%.It was concluded that more radical surgery should be used to treat head and neck carcinomas except nasopharyngeal carcinoma.
