title: Elevated IGA in carcinoma of the nasopharynx.
abstract: Fourteen patients with nasopharyngeal carcinoma were evaluated immunologically prior to standard radiotion therapy. All had elevations of serum IgA, ranging from 300 mg/100 ml to 1000 mg/100 ml, with a mean value of 549 mg/100 ml. Seven patients demonstrated depression of cell-mediated immunity as measured by delayed hypersensitivity skin tests, total lymphocyte count, in vitro stimulation with PHA, and T-cell rosette formation. Elevation of serum IgA associated with depression of cell mediated immunity may be characteristic of patients with nasopharyngeal carcinoma.
