[About the immunologic evidence of tumors in the E.N.T. field (author's transl)]

It is reported about first results of the immunologic evidence of E.N.R. tumors with the help of MEM-tests with application of HEP as antigen. The findings of 31 patients with tumours in the E.N.T. area are confronted with the results obtained from 116 tumour-free control persons and 108 patients with other swelling localisations. The sensitivity of the examinations of E.N.T. tumours was 89.3 p.c., i.e. especially favourable.
