REGRESSION OF PRIMARY LOW-GRADE GASTRIC LYMPHOMA OF MUCOSA-ASSOCIATED LYMPHOID TISSUE BY ERADICATION OF HELICOBACTER PYLORI INFECTION: CASE REPORT
Main Article Content
Abstract
Objective: the Authors report their experience in diagnosis and treatment of one case of primary low-grade gastric lymphoma of mucosa associated lymphoid tissue (MALT); recent international literature review.
Experimental Design: complete clinical report. Diagnostic, clinical and prognostic indication, evaluation of effectiveness of eradication therapy and short follow-up.
Setting: Operative Unit of General and Thoracic Surgery. University “Paolo Giaccone” of Palermo.
Intervention: treatment of H. Pylori infection (lansoprazole, amoxicillin and metronidazole twice a day for 14 days; after that, lansoprazole for another 4 weeks), according to international guide-lines.
Results: H. Pylori was completed eradicated. Disappearance and total regression of the lymphomatous tissue was observed. No relapse were recorded at short follow-up.
Conclusions: our reports confirm the recent anedoctal reports on regression of gastric MALT lymphoma after eradication of H. Pylori and indicates that the growth of these extranodal lymphomas may depend on H. Pylori.
