 In 22 cases of gastric MALT (mucosa-associated lymphoid tissue) lymphoma, clinical features and endoscopic types were compared after administrotic of antibiotics. Endoscopy revealed four types: Diffuse granular redness, localized depressed redness, localized discolored area, and protruded lesion, respectively. Most of the diffuse granular redness types responded to Helicobacter pylori (Hp) eradication therapy, but, within six months after eradication of Hp, these cases might merely be in the remission stage. Cases of Hp negative MALT lymphoma and MALT lymphoma accompanied with disseminated lesions show discolored lesions in the stomach. These lesions are not affected by Hp eradication therapy. Thus, our study of the clinicopathological features of MALT lymphoma in 22 cases, led us to the conclusion that wider clinical trials are required to assess more fully the effects of eradication of Hp on gastric MALT lymphoma.
