[Adenocarcinoma of the stomach: clinical and immunologic features]

Lower natural killer cells activity (NKCA), varying stage of anemia and in vitro depressed colony-forming ability of committed precursors of hemopoiesis were identified in 50 gastric cancer patients. The patients with different patterns of the vegetative nervous system had tumors with a range of adenocarcinoma cell differentiation. A relationship was established between anemia stage, colony-forming ability of committed precursors of hemopoiesis, on the one hand, and vegetative nervous system pattern, stage of tumor cell differentiation and, to a less extent, NKCA, on the other.
