Clinicopathologic and immunohistochemical study of surgically treated primary gastric MALT lymphoma

B‐cell MALT lymphoma is a well‐recognized entity and its characterization as low‐grade (LG) and high‐grade (HG) lymphoma has been widely accepted. In the present study we reviewed a series of 95 surgical specimens of primary gastric MALT lymphoma selected between 1979 and 1998. Immunohistochemical expression of p53, bcl‐2, and Ki67 and Helicobacter pylori (Hp) infection was evaluated, along with a correlation with clinical outcome.
