Abstract

A 53-year-old woman was seen at the hospital because of epigastralgia and was pointed out have multiple ulcer like lesions of the stomach on upper gastrointestinal series. Mucosa-associated lymphoid tissue (MALT) lymphoma was diagnosed by endoscopically obtained biopsy specimen. High serum antiboty titer for Helicobacter pylori (H. pylori) was noted. H. pylori was identified on the biopsy specimen using by polymerase chain reaction. Although H. pylori was completely eradicated by amoxicillin-metronidazole-bismuth subnitrate triple therapy and lansoprazole, MALT lymphoma did not disappeared. Thus, a total gastrectomy with lymph node dissection was indicated. The histological sections showed multifocal small lesions of lymphoma cells and medium-sized follicle centrocyte-like cell infiltration in the mucosa and submucosa. The intramucosal lesions showed lymphoepithelial lesions. These findings were indicative of MALT lymphoma. She had been doing without any signs of recurrence as of 13 months after the operation. Recently the relation between MALT lymphoma of the stomach and H. pylori has been indicated, and the disappearance of gastric MALT lymphoma due to eradication of H. pylori has been increasingly reported. We propose the guidelines for the treatment of MALT lymphoma that H. pylori is eradicated first and thereafter an operation is performed if it is ineffective. On the other hand, we should continue to conduct gastric endoscopy even after H. pylori disappear, and perform…

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
