Treatment of Metastatic Gervical Cancerous Nodes from an Unknown Primary Site

Guidelines for the optimal management of patients with cervical cancerous nodes from an unknown primary site, has not been yet settled. However, radical treatment has been advocated employing either a surgery, or radiotherapy, or combination of the two in relation to the location, stage and histologic features of nodes in the neck. Of 43 patients who presented with "Cervical metastases from an unknown primary" since 1971, 31.2% survived 3 years after adequate management. Combined modality with surgery and radiation showed more favorable treatment results: in local control rate, 3 year survival rates and the subsequent apperances of the contralateral side of neck node through the retrospective analysis. In 11 cases, the primary tumors became apparent later, carcinoma of the hypopharynx, being the most frequent site, rather than the nasopharynx.
