[Cellular immunity in human brain tumours (author's transl)].

44 patients with various intracranial tumours were examined for cellular immunity to their autologous tumours by the Leucocyte Migration Inhibition Technique (LMI) and by intracutaneous testing. A good correspondence was found in the two tests but LMI seemed to be the more sensitive method. Cellular immunity was found in 3 out of 18 patients with malignant gliomas, in 6 of 16 cases with slower growing gliomas, in 5 of 6 patients with brain sarcoma and in 1 out of 4 patients with meningioma.
