In the period from 1960 to 1980, 21 patients with cervical lymph node metastasis from unknown primary cancer were treated. They were 1.5% of the patients with malignant tumors of the head and neck region treated during the same period. The presence of primary lesions were confirmed in 7 patients after the treatment of their metastatic lesions. In the group of patients whose metastatic lesions were treated by surgery, four survived more than five years. In one of the 4 patients, the primary lesion was found later, and treated by radiation and surgery. None of the patients whose metastatic lesions were treated by radiation or chemotherapy survived. When the metastatic lymph nodes are not fixed and limited at unilateral side of the neck, surgical treatment by radical neck dissection is recomended.
