title: Cervical lymph node metastases from an unknown primary tumour.
abstract: Forty-nine cases of cervical lymph node metastases from an unknown primary tumour have been reviewed. All the patients were treated by radiation therapy. In 7 cases the primary tumour was detected from 4 to 53 months after the end of treatment. The crude survival rates at 2 and 5 years were 39 and 32 per cent, respectively. The survival rate was correlated to sex, microscopic appearance, stage, and extent of the nodal involvement.
