[Clinico-pathological study of autopsy cases of nonresected gastric cancer in the young and old].
To elucidate the difference between the natural history of gastric cancer in young and old patients, this study was carried out. Fifty-four cases were studied, representing the autopsy findings of gastric cancer patients who did not undergo operation. The characteristics of the gastric cancer in the young patients were as follows: had infiltrative macroscopical types, had histologically diffuse types, had deeper and wider infiltration, showed a severer invasion into the vessels, and, showed marked lymphatic disseminated, and distant metastasis. The elderly, in comparison, showed various types of gastric cancers. The extension of the cancer in the old group was significantly, less than in the young, even in the same diffuse type. The period from the onset to death was almost same in both groups. The age of the host seems one of the important factors influencing the natural history of gastric cancer.
