[A study of cases of early gastric cancer with hematemesis and/or melena].
In this hospital, gastric cancers showed a slightly lower incidence (9.3%) of hematemesis and/or melena than gastric ulcers (13.9%), and no distinct difference in such incidence between early gastric cancers and advanced gastric cancers was observed. A study of the literature on early gastric cancers presenting such symptoms revealed that male patients showed an extremely high incidence of these symptoms, as did those with depressed lesions, including types II c + III, and lesions occurring in the MC-C regions dominated by the left gastric artery.
