| [ Summary ] | Magnifying endoscopic diagnosis of the extent of gastric cancer should be performed with the following three points : evaluating the background mucosa of the cancerous lesion, diagnosing the cancer margin according to mucosal and or vascular pattern, and diagnosing the extent of cancer. Recently, gastric cancer after a successful eradication therapy has been found to be difficult to diagnose because of its gastritis‒like appearance. Magnifying endoscopic diagnosis of the extent of gastric cancer after a successful eradiation should be performed upon confirmation that it shows a gastritis‒like appearance. Magnifying endoscopic observation should be done including the non‒cancerous mucosa, with attention to the difference in mucosal pattern from the background mucosa. Finally, the mucosal pattern and vascular pattern should be carefully observed. | |
