• Tumour size, invasive and metastatic potential were closely related to the presence or absence of carcinoembryonic atigen (CEA) in gastric cancer as detected by an immunofluorescent technique. Patients with CEA positive gastric cancer had a better prognosis. Extensive connective tissue proliferation and macrophage infiltration were observed, especially around tumours of patients with CEA positive gastric cancer. Thers are interpreted as immune reactions against tumor.CEA positive gastric cancers were usually non-invasive; restricted to the antrum; microscopically well-differentiated; and surrounded by inestinal metaplasia. The result suggest that CEA positive gastric cancers bear great similarity to the intestinal carcinomas defined by Dr. Nakamura.
