The correlation among lymphoid cell infiltration (LI), cell-mediated immunity and immunoglobulin-containing cells distribution in the colon cancer was studied in resected materials of 136 patients with colonic cancer.
The results were as follows:
1) LI of the colon cancer tended to be found more commonly in patients with colonic cancer in clinical early stage than advanced stage.
2) The cumulative 5-year survival rate in patients with positive LI was longer than that in the patients with negative or normal LI.
3) In colonic cancer patients with the better prognosis, IgA-containing cells were distributed around the tumor tissues more abundantly than that in the poor ones.
4) These results suggest that the IgA system somewhat participates in cancer immunity.
