[Attempts at the introduction of a clinico-immunological therapy for malignant tumors]

The basis for an immunoncological therapy was investigated by culture of lymphocytes incubated with autologous tumor-antigen. The methods of isolation and cultivation are adapted to conditions of reinfusion. The effectiveness of tumor-aggressive action is demonstrated as transformation to lymphoblasts (indirect action) and tumor-cytolysis (direct action) in mixed lymphocyte-tumorcell culture.
