Metastatic squamous cell carcinoma of an unknown primary tumor localized to the neck.
68 patients with metastatic squamous-cell carcinoma (SCC) of an unknown primary tumor localized to the neck were treated between 1981 and 1990. There were 11 patients treated with radiotherapy alone, 24 patients treated with surgery and radiotherapy and 33 patients treated with radiotherapy and chemotherapy. Male to female ratio was 1.9:1 and the median age was 55 years (range, 33 to 71 years). 41 (61%) patients had N3 disease, 18 (26%) patients had N2 disease and 9 (13%) patients had N1 disease. The majority of N3 patients were treated with radiotherapy + chemotherapy (n = 17) and surgery + radiotherapy (n = 17). The complete response (CR) to radiotherapy + chemotherapy was 73% with 19 patients having no evidence of disease currently. The median survival time (MST of this group was 34+ months. Of the 35 patients who had surgery and/or radiotherapy, 7 (20%) currently have no evident disease. The MST of these two groups (combined) was 22 months. Patients with N3 disease who received radiotherapy + chemotherapy had a higher CR rate and longer MST when compared with those without chemotherapy.
