[Initial results of a simple immunological study of E.N.T. carcinomas (author's transl)].

45 patients suffering from carcinomas of the upper airway and digestive tract were studied from an immunological standpoint, by estimation of serum immunoglobulins and by a series of skin tests. This latter technique gave the most interesting results. It showed that immunodepression is statistically more frequent in extensive forms and that the prognosis in immunodepressed patients is much more severe than in those who have retained normal immune reactions.
