Abstract
We conducted a clinico-histopathological investigation on 18 cases of gastric cancer with coexisting intra-gastric lesions. Most cases of gastric cancer that were complicated by gastric ulcers were the excavated type. Well and poorly differentiated types were, basically, equally represented. Almost all coexisting ulcers were U1-II or U1-IlI types, and most of them were scars. The cancers were usually located on the pyloric side of the ulcers. All cases of gastric cancer that were complicated by duodenal ulcers were the excavated type. The cancers existed in the antrum. Coexisting ulcers were either U1-III or U1-IV, indicating deep invasion. Gastric cancers complicated with ATP were mostly elevated types, which tended to be situated slightly oral position from those complicated by gastric ulcers. The depth of invasion in all cases was mucosal, the histopathological type of which was well differentiated tubular adenocarcinoma. Only one case of gastric cancer had a polyp. As a result, gastric cancer complicated with coexisting intra-gastric lesions tended to grow, and imitate the form of the coexisting lesions. Most cases of gastric cancers with coexisting lesions were in the early stages. It is thus necessary to discover gastric cancer as soon as possible by thorough and periodic observation and follow-up, not only of the lesions themselves, but of other parts of the stomach.
