Immunologic reactivity was measured in 344 patients with nasopharyngeal carcinoma (NPC), before treatment, and in 398 age-matched control subjects. The data recorded suggest that depressed cell-mediated immunity in patients with NPC is a consequence rather than a cause of the disease. In order to reduce tumor burden in patients with NPC, radiation therapy with chemotherapy or immunopotentiation or both is recommended.
