Cellular antitumor immunity in an autologous system in stomach cancer

: Positive reaction to autologous tumor extracts in leucocyte migration inhibition test was established in one-third of stomach cancer patients under study. Responses with donor serum and autologous sera of blood were not identical. A significant correlation between response to autologous tumor extract in the presence of donor serum and survival time was found. Positive reaction with autologous serum proved to be bad prognosis. The results point to the prognostic value of antitumor immune reactions in autologous system in stomach cancer. Autoimmune reactions to organic antigens of the mucosa are indispensable in the interpretation of antitumor specificity of reactions.
