Management and outcome of cervical lymph node metastases of unknown primary sites: a retrospective study

Analysis of the case records of 114 patients with cervical lymph node metastases from unknown primary sites showed that management should be adapted according to the site of nodal disease and the histopathology. Poorly differentiated carcinoma was best treated with radiotherapy, squamous cell carcinoma with radiotherapy and excision, and non-papillary adenocarcinoma by radical thyroidectomy and neck dissection. The 5-year survival for each regimen alone, was 15/40 (38%), 7/13 (54%) and 5/8 (63%), respectively. For metastatic masses in the supraclavicular region, chemotherapy was the preferred treatment. The overall survival for the 107 patients who completed the follow up was 36%.
