Lymphoid Infiltration in Cancer and Cell-Mediated Immunity in Gastric Cancer

The pathological changes of regional lymph nodes in cases of gastric carcinomas with lymphoid stroma (LS group) and the prognostic significance of the findings were studied in comparison with those in cases of ordinary stroma (OS group). The purpose of this study was to elucidate the immune responses of regional lymph nodes, histologically, in patients with gastric carcinoma and lymphoid stroma. In the LS group, the incidence of paracortical hyperplasia (PH) was high, irrespective of lymph node metastasis, while that of germinal center hyperplasia (GH) was high in the absence of lymph node metastasis but tended to be low in the presence of metastasis. In the OS group, the incidences of PH and GH were low, particularly in the presence of lymph node metastasis. The five year survival rate in those with no lymph node metastasis was as favorable as that of patients with lymph node metastasis in the LS group, the latter being significantly higher than the rate in the OS group. These results indicate that gastric carcinomas with lymphoid stroma are closely related to reactive hyperplasias of the regional lymph nodes, particularly paracortical hyperplasia, and in such cases, there is a favorable prognosis, regardless of the lymph node metastasis.
