Sera from 60 gastric cancer patients and 20 patients with benign gastric diseases and 8 healthy controls were tested for inhibitory effects on the humoral response to sheep erythrocytes (SRBC) by the plaque forming cell assay (PFC R.I.) using mouse spleen cells and on the phytohemagglutinin (PHA)-induced blastogenesis of normal mouse spleen cells (PHA S.R.). Gastric cancer patient sera showed a significantly lower PFC R.I. than did sera from benign gastric disease patients and from the healthy controls. However, there was no appreciable interstage difference in the degree of depression. The PHA-induced blastogenesis of normal spleen cells was also decreased in the presence of sera from cancer patients, as compared to that in the presence of sera from benign disease patients and from the healthy controls. The depression progressed with advancing stage of cancer. The PHA S.R. showed significant negative correlations with serum levels of IAP, IS, α-acid glycoprotein and α-antitrypsin, but there were no such correlations between PFC R.I. and these glycoproteins in serum. There was also no correlation between the values of the PHA S.R. and the PFC R.I. These results suggest that these two assays may depict immunosuppressive activities operating through entirely different mechanisms. [ABSTRACT FROM AUTHOR] |
