The author studied the host-tumor relationship with the cellular and humoral response of the R. E. S. in the patients with gastric carcinoma. The cases with in-creased function of the R. E. S. showed low grade spread and metastasis of carcinoma to lymph nodes, and also better 5 years survival rate. Consequently, disorders of the local and general R. E. S. showed a marked effect on the growth and prognosis of tumor.
The author considers that these responses of the R. E. S. in the cancer patient seem to be anti-tumor like result.
