Abstract

served in 50 cases (21.0%). Tumor positivity was high in ulcerated lesions (2/3, 66.7%), erosion (1/5, 20.0%), discoloration (32/89, 36.0%), mucosal thickening (10/41, 24.4%) and ulcer scars (3/21, 14.3%). Conversely, lesions appearing normal showed low pos- itivity (1/68, 1.5%) and was significantly lower compared with the aforementioned lesions (P<0.001). Conclusions: Endoscopic appearances of depression, discoloration, mucosal thickening and ulcer scars were more likely to have tu- mor cells and should be targeted during follow up for gastric MALT lymphoma.
