Endoscopic surveillance of gastric cancers after Helicobacter pylori eradication

Figure 4 Differentiated-type early gastric cancer detected after successful Helicobacter pylori eradication. A: Chromoendoscopy revealed a depressed-type lesion in the anterior wall of the antrum; B, C: Narrow-band imaging with magnified endoscopy shows a “gastritis-like” appearance with a microsurface structure comprising of regular papillae resembling with unclear demarcation between the cancer and surrounding gastritis mucosa; D: Well-differentiated tubular adenocarcinoma with low-grade atypia (hematoxylin and eosin staining); E: MUC5AC immunohistochemical staining demonstrates that superficial non-neoplastic epithelium is interspersed among and above the cancer tubules[47].
