Clinical Analysis of 29 Cases With Primary Gastric Mucosa-associated Lymphoid Tissue Lymphoma

Objective: To improve the early detection rate of gastric mucosa-associated lymphoid tissue (MALT) lymphoma by analyzing its clinical, endoscopic and pathological features. Methods: Clinical data of 29 patients with gastric MALT lymphoma confirmed by endoscopic biopsy and the pathological findings of tissues obtained from surgical operation were analyzed retrospectively. Results: Various clinical features were seen in 29 patients, in which upper abdominal pain was the most common one and the rate of helicobacter pylori (HP) infection was 93%. The lesions commonly located at gastric antrum and gastric corpus endoscopically, but with a lower positive rate (48%) by endoscopic biopsy. Conclusions: There were no special clinical features in patients with gastric MALT lymphoma, and with diverse endoscopic features. To improve the recognition of the disease and increase the positive rate of endoscopic biopsy with immunohistochemical strains play the key roles for the early diagnosis of gastric MALT lymphoma.
