[Suppressor function of the blood lymphocytes in patients with stomach cancer undergoing gastrectomy combined with splenectomy].

Suppressor status of immunity in 34 patients with gastric cancer of the III-IV stages was studied before and after (15 days and 3 months) gastrectomy and gastrosplenectomy. The control group consisted of 42 healthy donors. It was shown that gastrectomy caused inhibition of the endogenous activity, but stimulated the function of the prostaglandin-producing suppressor cells while combined gastrosplenectomy induced inhibition of the function of both endogenous and prostaglandin-producing suppressor cells.
