Clinicopathological and molecular data of 28 patients with low grade MALT lymphoma

Patients	Age/sex	Origin	Macroscopic type	Depth of invasion	Helicobacter pylori	Treatment	Effect of H pylori eradication	Modified Ann Arbor stage	API2–MLT fusion
Depth of invasion: m, mucosa; mp, muscularis propria; se, serosa; sm, submucosa; ss, subserosa. Treatment: Chemo, chemotherapy; Erad, H pylori eradication; Rad, radiation; Surg, surgery. Effect of eradication: CR, complete regression; PR, partial regression; NR, no regression. *Only the gastric lesion regressed completely in patient 11.
MALT, mucosal associated lymphoid tissue; NA, not available.
