Abstract | BACKGROUND: The utility of magnifying endoscopy for diagnosis of epithelial tumors has been reported, but there are few reports for nonepithelial tumors. OBJECTIVE: DESIGN: This was a retrospective study. SETTING: Endoscopy Unit, Hokkaido University Hospital. PATIENTS: INTERVENTIONS: The microstructural pattern, collecting venules, and abnormal vessels in gastric MALT lymphoma were assessed before treatment and at 4 to 7 months after treatment by using magnifying endoscopy. MAIN OUTCOME MEASUREMENT AND RESULTS: The characteristics of magnified endoscopic images before treatment were the disappearance of gastric pits and the appearance of abnormal vessels. Ten cases of Helicobacter pylori-infected MALT lymphoma were treated by H. pylori eradication, and 1 H. pylori-negative case was treated by radiation therapy after eradication therapy. Ten patients achieved complete disease remission. After the treatment, recovery of gastric pits and subepithelial capillary network, and the disappearance of abnormal vessels were revealed by magnifying endoscopy. LIMITATION: This was a small pilot study. CONCLUSIONS: Magnified findings of gastric MALT lymphoma before and after therapy seem to correlate with complete response and no response.
