High grade B-cell gastric lymphoma with complete pathologic remission after eradication of helicobacter pylori infection: Report of a case and review of the literature

摘要

BackgroundTreatment of primary gastric diffuse large B-cell lymphoma is still controversial. The treatment of localized disease was based on surgery alone, or followed by chemotherapy and/or radiotherapy. High-grade gastric lymphomas are generally believed to be Helicobacter pylori (HP)-independent growing tumors. However a few cases of regression of high-grade gastric lymphomas after the cure of Helicobacter pylori infection had been described.
