Surveillance endoscopies were performed twice a year in accordance to the protocol. Four years aftercomplete lymphoma remission in two patients,and after 5 years in the other, early gastric adenocarcinoma of the mucosa-type, type Ⅱ a and type Ⅱ c, respectively, was detetcted,which were completely removed by endoscopic mucosa resection. in one patient, the gastric cancer was diagnosed at the same location as the previous. MALT lymphoma, in the other patients it was detected at different sites of the stomach distant from location of the previous MALT lymphoma. The patients were H. pylori negative during the whole follow-up time.CONCLUSION These findings strengthen the importance of regular long-term follow-up endoscopies in patients with complete remission of gastric MALT lymphoma after cure of H.pylori infection. Furthermore, gastric adenocarcinoma may develop despite eradication of H. pylori.展开更多
