[Cellular immunity in melanomalignome (author's transl)].

Cellular immunological reactivity was examined in 20 patients having melanomalignoma at different clinical stages, using Leukocyte-Migration-Inhibition-Test. As antigens three homologous melanoma-extracts were used, produced by our own method. Independent from the clinical stages cell-migration inhibition could be established in 15 out of the 20 patients. In this way, these tumor extracts have been shown to contain melanoma-associated antigens. Regardless of the clinical stage of the disease, the melanomalignomas patient produces cellular immunity against those tumor-antigens. It is note-worthy that the actual course of the disease seems not to be influenced by immun-mechanisms.
