Primary Gastric Lymphoma.
BACKGROUND: Gastric lymphoma is a common presentation of non-Hodgkin's lymphoma. Controversy reigns about many aspects of its classification and management, especially regarding roles for surgical resection. METHODS: The authors review the clinical features, staging, pathology, prognosis, and management issues with an emphasis on the role of surgical resection. RESULTS: Staging usually can be completed using noninvasive techniques. Those with a low-grade B-cell MALT type lymphoma with Helicobacter pylori infection may be treated with antibiotics and close follow-up. Patients with stage I or II disease may be treated with chemotherapy and radiation. Surgery is indicated for those with perforation or uncontrolled bleeding. CONCLUSIONS: Gastric lymphoma, primarily a B-cell tumor, can be diagnosed and managed effectively with various approaches. Few prospective, randomized trials of alternative approaches have been performed.
