[Immunologic reactivity in different courses of stomach cancer]

The immunological status was examined in 106 patients with cancer of the stomach, who were subjected to different operative interventions. 74 of them were considered to be operable and 32-inoperable. The immunological activity was compared (according to the tests of cell immunity and general immunological reactivity) in aggressive--unfavourable and torpid-favourable course of the disease. A torpid course of the lesion after surgery for gastric cancer was associated with stabilization and some activation of immune response indices. However, radical operations fail to provide the normalization of these tests, and the state of immune depression in the patients would persist. An aggressive course of the lesion after surgery for gastric cancer was associated with considerable shifts in immunological tests indices toward their suppression, these being increased with the approach of patient's death.
