Endoscopic features and clinical analysis of primary gastric malignant lymphoma:A report of 14 cases

Objective To investigate the endoscopic features of primary gastric malignant lymphoma(PLML) and its clinical diagnosis and therapy.Methods The clinical data and endoscopic phenotype in 14 cases of PLML from 1995 to 2009 were retrospectively analyzed.Results In the 14 cases,5 were male and 9 were female.The median age was 54.Classification by type,2 were mass,7 were ulcer,2 were infiltration,and 3 were nodule.Among them,one patient was Hodgkin's disease and 13 were non-Hodgkin's disease(12 cases were B cell source and 1 was T cell source).Ten patients were conducted the surgery.The 2-year survival rate was 54.5%,and the 5-year survival rate was 27.3%.Two patients with mucosa associated lymphoid tissue(MALT) lymphoma were treated by anti Helicobacter pylori(HP) and chemical therapy.Conclusion Primary gastric malignant lymphoma is difficult to diagnose.Its diagnosis can be improved by the combination of gastroscope and pathology.The therapeutic effect needs to be monitored by the follow-up observation.
