 To clarify the clinical features of gastric MALT lymphoma(GML)with persistent lymphoma after eradication therapy of Helicobacter pylori(H. pylori), and the outcome of long-time follow-up study after treatment against GML, seventy-six patients with localized GML were studied. The median follow-up period was 44.4 months. Thirty-eight of 49 patients(77.6%)with H. pylori-positive GML had been cured of GML by antibiotic therapy alone. On the other hand, none of 13 patients with H. pylori-negative GML had been cured by antibiotic therapy(77.6%vs 0%, p<0.001)."H. pylori-negative"is one of the clinical features of antibiotic-resistant cases with GML. There was no significant difference in sex, age, stage, endoscopic finding, depth, and affected region between the two groups of cured and persistent GML with H. pylori infection. Twenty-two of 29 patients(75.6%)with antibiotic-resistant or H. pylori-negative cases of GML had been cured by 30 Gy radiation therapy. Low-dose radiation was thought to be a useful therapeutic procedure as a"second line treatment"of localized GML.
