[Suggestions on the control and stimulation of cellular immunity in cancer].

Seventy patients suffering from cancer have been treated since 1969 with intracutaneous injections of autogenous carcinoma cells. This should stimulate cellular immunity through the skin. A stimulation and reactivation of cellular immunity seems to be possible. The cellular reaction at the injection site supplied useful hints for the evaluation of the state of immunity. The possibility of improving cellular resistance through immune gamma globulin in pigs treated with carcinoma cells is discussed.
