title: General considerations on distant metastases from head and neck cancer.
abstract: Mortality in head and neck cancer is due to locoregional disease, distant metastases or intercurrent disease. As treatment of the primary tumor and cervical metastases has improved, the proportion of deaths from co-morbidity and from distant metastases has increased. Distant metastases almost invariably herald a poor prognosis in head and neck cancer with an average survival of 4.3-7.3 months and treatment is usually palliative. Reliable detection is important to prevent inappropriate treatment. The risk is related to the site, stage and histology of the primary tumor and the presence of cervical metastases. Early detection and treatment of cervical metastases may prevent distant metastases. Accurate staging of tumors helps to identify high-risk tumors that should be specifically investigated for distant metastases.
