AIM:To analyze the clinicopathologic characteristics ofsurgically resected gastric lymphoma patients.METHODS:We retrospectively analyzed 57 surgicallyresected gastric lymphoma patients,dividing them into 2subgroups:Low grade MALToma (the LG group),High gradeMALToma and Diffuse large B cell lymphoma (the HG group).RESULTS:The numbers of patients were:20 in the LG group,37 in the HG group.The diagnostic rate of gastroscopy was34.8% at primary diagnosis and 50% including differentialdiagnoses.The positive rates of Hpyloriwere similar betweenthe 2 groups (68% vs77%).Multiple lesions were found in19.3%.The proportion of mucosal and submucosal lesionswas 80.0%(16/20) in the LG group,and 24.3%(9/37) inthe HG group (P<0.001).Lymph node invasion rates were10.5%(2/19) in the LG group and 44.1%(15/34) in the HGgroup (P=0.031).The numbers of recurred patients werenone in the LG group,and 8 in the HG group.By univariantanalysis,group (P=0.024) and TNM stage (stage Ⅰ,Ⅱ vsstages Ⅲ,Ⅳ,P=0.002) were found to be the significantrisk factors.There was a tendency of higher recurrence ratein the subtotal gastrectomy group than in the total gastrectomygroup (P=0.50).CONCLUSION:The HG groups had a more advanced stageand a higher recurrence rate than the LG group.Althoughthere was no difference between subtotal and totalgastrectomies,more careful assessments of multiplicitiesand radical resections with lymph node dissections seemto be needed because of multiplicity and LN invasion evenin LG group.
AIM: To analyze the clinicopathologic characteristics of locally resected gastric lymphoma patients. METHODS: We retrospectively analyzed 57 surgicallyresected gastric lymphoma patients, dividing them into 2 subgroups: Low grade MALToma (the LG group), High grade MALToma and Diffuse large B cell lymphoma (the HG group ) .RESULTS: The numbers of patients were: 20 in the LG group, 37 in the HG group. The diagnostic rate of gastroscopy was 34.8% at primary diagnosis and 50% including differential diagnosis of the positive rates of Hpyloriwere similar betweenthe 2 groups ( 68% vs 77%). Multiple lesions were found in 19.3%. The proportions of mucosal and submucosal lesions were 80.0% (16/20) in the LG group, and 24.3% (9/37) inthe HG group (P <0.001) . Lymph node invasion rates were 10.5% (2/19) in the LG group and 44.1% (15/34) in the HGgroup (P = 0.031). The numbers of recurred patients werenone in the LG group, and 8 in the HG group.By univariantanalysis, group (P = 0.024) and TNM stage (stageⅠ, Ⅱ vsstages Ⅲ, Ⅳ, P = 0.002) were found to be the significant change in the subtotal gastrectomy group than in the total gastrectomy group (P = 0.50). CONCLUSION: The HG groups had a more advanced stage and a higher recurrence rate than the LG group. Although there was no difference between subtotal and totalgastrectomies, more careful assessments of multiplicitiesand radical resections with lymph node dissections seemto be needed because of multiplicity and LN invasion evenin LG group.
