 Many early gastric cancers were completely treated by endoscopic resection, but early gastric cancers with ulceration were difficult to treat by endoscopic resection. We retrospectively examined patients who received endoscopic resection or surgery for depressed type early gastric cancers, and examined the characteristics of early gastric cancer with ulceration. Patients having early gastric cancer with ulceration were younger(p<0.0001), the size of lesions was larger(p<0.0001), the rate of invasive cancers to the submucosal layer was greater(p<0.0002), and the rate of undifferentiated cancers was greater than early gastric cancers without ulceration. The concordance rate for presence or absence of ulceration by endoscopic diagnosis and pathological diagnosis was 89%, however different diagnoses showed, there were some cases in which the presence of ulceration was overlooked by endoscopy.
