[Subpopulations of T and B lymphocytes in venous peripheral blood and blood draining from lesions in patients with gastroduodenal ulcer, and gastric and colonic cancer].
In 30 patients with gastric and colonic cancer and 30 patients with gastroduodenal ulcer treated in a surgery department the absolute number and per cent of leucocytes, number of lymphocytes, active T-rosettes, B-cells, T-cells, populations of helper T-cells, suppressor T-cells, and T4/T8 ratio were determined in peripheral venous blood and venous blood draining the lesion. On the basis of these studies it was found that in patients with gastroduodenal ulcer and gastric and colonic cancer a decrease occurs of the number of immunocompetent cells, particularly of T-cells and helper T-cells. In patients with cancer a decrease was observed in the region of tumour particularly of the size of helper B and T-cells populations.
