Core Tip

Core tip: Although the majority of gastric mucosa-associated lymphoid tissue (MALT) lymphoma patients are infected with Helicobacter pylori (H. pylori), approximately 10% of patients do not have H. pylori infection. Recent studies have demonstrated that eradication therapy for H. pylori is effective not only for H. pylori-positive but also for H. pylori-negative gastric MALT lymphoma patients.
