Abstract
The effects of anticancer agents were studied on the basis of survival rates following surgery for gastric carcinomas in different histologic types of Lauren's classification. It was revealed that Lauren's classification would provide an index to the use of anticancer agents to a certain extent. Anticancer agents were effective against diffuse gastric carcinoma, and should therefore be intensively used for treatment of this malignancy. For female patients with diffuse gastric carcinoma, careful selection of adequate anticancer agents is highly necessary. Anticancer agents were less effective against intestinal-type carcinoma, and it would therefore be necessary to use anticancer agents on the aged male patient with this malignancy by taking his age and side effects of the agents into consideration.
