[The concept of the "artificial tumor"]

Basic theoretical and experimental preconditions for the creation of the so-called "artificial tumour" are examined. It should be an operated extracorporeal analog of the spontaneously growing blastoma with autologous tumour cells as the main structural and functional element. Construction principles and immunological aspects of the "artificial tumour" are discussed. The real potentialities of its usage for the selective elimination of the tumour-stimulating humoral factors of different origin out of the organism as well as for the specific activation of autologous effector immunocytes are analyzed.
