Cervical metastasis of unknown origin is still a challenging problem because of its relatively poor prognosis and the uncertainty regarding the primary site. We analyzed retrospectively all 72 patients with cervical metastases of unknown origin, diagnosed and treated between 1985 and 1995 in the five university hospitals of Finland in order to analyze survival rates and some prognostic and clinical factors of the disease. The most common sites where the primary tumor was found during follow-up or at autopsy were the lung (8%), the oral and pharyngeal region (7%) and the skin (6%). When the lower neck nodes (regions IV-VI) were affected, the primary tumor was significantly (p<0.001) more often found from the subclavicular sites. The disease-specific 5-year survival rate was 32%. In multivariate analysis, nodal stage N2c or N3 [adjusted relative hazard of death (HR) 2.43], other metastases found at the time of treatment (HR 2.15) and age > 65 years (HR 2.12) were significantly associated with a poor prognosis. Median survival tended to be longer for patients treated with surgery combined with radiotherapy (39.9 months) compared with those treated with radiotherapy alone (16.8 months), but this difference was not statistically significant (p=0.153).
