Prognostic factors and outcome for nasopharyngeal carcinoma.

Background: Nasopharyngeal cancer (NPC) is a distinct form of cancer of the upper respiratory or digestive tract in which the epidemiologic features, origin, histopathologic types, treatment, and prognosis are different from those associated with other malignant neoplasms of this anatomical area. Recent publications have demonstrated the advantage of aggressive multimodality treatment for advanced NPC.

Objectives: To evaluate the results of standardized treatment of NPC during 11 years and to identify pertinent factors for clinical outcome.
