Overview

The most potent risk factor in the development of gastric MALT lymphoma is H.pyroli infection. About 5–10% of people with gastric MALT lymphoma do not have an H. pylori infection (H. pylori negative). Other risk factors for gastric MALT lymphoma include long-term immunosuppressant drug therapy and HIV infection. Common risk factors in the development of MALT lymphoma, in areas of the body other than the stomach, are autoimmune disorders such as Hashimoto's thyroiditis, Sjogren’s syndrome, and Celiac disease.
