  5. Nasopharyngeal Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for Nasopharyngeal Cancer

    Staging systems are all clinical staging and are based on the best possible estimate of the extent of disease before treatment.[1,2] Assessment of the primary tumor is based on inspection and palpation, and fiberoptic endoscopic evaluation. The tumor must be confirmed histologically, and any other pathologic data obtained on biopsy may be included. Evaluation of the function of the cranial nerves is especially appropriate for tumors of the nasopharynx. The appropriate nodal drainage areas are examined by careful palpation and radiologic evaluation. The retropharyngeal lymph nodes are the first echelon of drainage.[3,4] Information from diagnostic imaging studies may be used in staging. Magnetic resonance imaging provides additional information to computed tomographic scanning in the evaluation of skull base invasion and intracranial spread.[5] Positron emission tomography scans combined with CT are helpful in radiation treatment planning for target delineation of the primary
