Nasopharyngeal carcinoma: treatment results with primary radiation therapy.

Bailet JW, Mark RJ, Abemayor E, et al.

Abstract:

One hundred three patients with nasopharyngeal carcinoma were treated with radiotherapy at UCLA Medical Center from January 1955 to December 1990. Overall survival, disease-free survival, and local control rates were analyzed. In addition, survival from 1955 to 1978 and from 1979 to 1990 were evaluated. Overall 5- and 10-year actuarial survival rates for all patients were 58% and 47%, respectively. Disease-free survival rates at 3 and 5 years were 45% and 30%, respectively. Local, persistent, or recurrent disease in the nasopharynx was the primary cause of failure, occurring in 32% of patients and correlating with the initial tumor size (T stage). Twenty-four percent of patients developed distant metastases, which correlated with nodal status but not with T stage. Seventy-nine percent of patients failed either locally or distally by 4 years. Sex, race, age, and T and N stage categories were evaluated as prognostic variables in terms of survival. Control of primary disease is important in determining long-term outcome. Modern imaging techniques have greatly assisted in the evaluation of disease extent and treatment options.
