title: Flat and depressed types of early colorectal cancers: from East to West.
abstract: Recent advances in colonoscopy have enabled us to diagnose early-stage colorectal tumors. Magnifying colonoscopy is useful for diagnosing histologic types by assessing the microstructure of the mucosal surface in detail, which also helps to predict the depth. This article describes clinicopathologic features and endoscopic treatment of flat and depressed types of early colorectal carcinoma.
