[Result of radiation therapy of carcinoma of the nasopharynx: an analysis of the patterns of relapse].
From 1965 through 1985, 85 patients with carcinoma of the nasopharynx were irradiated with curative intent at the Department of Radiation Therapy, Aichi Cancer Center Hospital. The observed 5-year survival rate was found to be 34%. Local recurrence was observed in 15 cases, regional lymph node recurrence in 10 cases, local and regional lymph node recurrence in 2 cases and distant metastases in 24 cases. Most manifestations of recurrence appeared within 2 years after treatment. Local recurrence was often observed in the base of skull in patients in advanced stages of their disease (T 3-4). The likelihood of a distant metastasis was stronger in patients with a bilateral neck nodes metastases and/or a lower neck metastases.
