ABSTRACT
BACKGROUND/AIMS:
Helicobacter pylori eradication therapy has been used as a first-line treatment for H. pylori-positive gastric mucosa-associated lymphoid tissue (MALT) lymphoma. However, the management strategy for H. pylori-negative MALT lymphoma remains controversial. Therefore, the aim of this study was to examine the success rate of each treatment option for H. pylori-positive and H. pylori-negative gastric MALT lymphomas.METHODS:
In total, 57 patients with gastric MALT lymphoma diagnosed between December 2000 and June 2012 were enrolled in the study. The treatment responses were compared between H. pylori-positive and H. pylori-negative gastric MALT lymphomas.RESULTS:
Of the 57 patients, 43 (75%) had H. pylori infection. Forty-eight patients received H. pylori eradication as a first-line treatment, and complete remission was achieved in 31 of the 39 patients (80%) with H. pylori-positive MALT lymphoma and in five (56%) of the nine patients with H. pylori-negative MALT lymphoma; no significant difference was observed between the groups (p=0.135). The other treatment modalities, including radiation therapy, chemotherapy, and surgery, were effective irrespective of H. pylori infection status, with no significant difference in the treatment response between H. pylori-positive and H. pylori-negative MALT lymphomas.CONCLUSIONS:
H. pylori eradication therapy may be considered as a first-line treatment regardless of H. pylori infection status.Key words
