Abstract

A patient is diagnosed with an unknown primary of the head and neck when metastatic disease is present in the cervical lymph node or nodes and no primary lesion is detected by thorough physical examination, directed biopsies of suspicious or most likely primary sites, and imaging studies. The optimal management of patients who have this syndrome is still unclear and controversial. We report our results and analysis of the management of 24 patients with this syndrome. From 1976 through 1992, 24 patients who had metastatic squamous cell carcinoma in the cervical lymph nodes were seen in our medical center. A thorough search did not detect a primary lesion in any of them. Patients underwent radical neck dissection of the involved neck; 23 had unilateral and I had bilateral neck disease. Postoperative radiotherapy was delivered to both sides of the neck and to the potential primary mucosal and submucosal sites. The relation between clinical N stage, histologic findings of numerous involved lymph nodes, presence of extracapsular tumor extension, and survival were statistically analyzed. The Kaplan-Meier method was used for the survival analysis. The p values of log-rank test for the comparison of the two groups 1) N1 and N2 versus N...Continue Reading
