[Gastric Mucosa-associated Lymphoid Tissue Lymphoma Based on Outcome of Domestic Treatment].

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is associated with infection. eradication can be performed as a primary therapy regardless of status. In Korea, six articles were published about low-grade gastric MALT lymphoma with . Complete regression rate after eradication is reported at 74.5% to 94.4%. Radiotherapy results in favorable clinical long-term outcomes in patients with early-stage gastric MALT lymphoma who fail eradication therapy and those who are negative. Chemotherapy could be reserved for patients with metastatic or high-grade lymphoma. In gastric MALT lymphoma, patients with polypoid type on initial endoscopy had a higher likelihood of recurrence than those with diffuse infiltration or ulceration types. The depth of invasion, location of lesions, and chromosomal abnormality with t(11;18) together are predictive factors for failure to remission by eradication.
