[Dynamics of indices of the natural resistance of patients with cancer of the stomach].

The most decrease in the indices listed was noted in patients with stage IV gastric cancer. The results of the tests mentioned permit to judge about the state of the non-specific resistance of the body of patients with gastric cancer, and in the complex with the other clinico-laboratory findings are of prognostic value.
