Abstract:
Objective To explore the differences and similarities of clinical characteristics,pathological features, treatment and prognosis between primary gastric lymphoma(PGL)and primary intestinal lymphoma (PIL). Methods The clinical characteristics, pathological features, therapeutic results, the detection of Helicobacter pylori (Hp) and prognosis of 48 PGL cases and 15 PIL cases were retrospectively analyzed. Results There was no statistical significance in age, gender, abdominal pain, gastrointestinal bleeding, B symptoms, clinical stage, mortality between PGL and PIL groups (P>0. 05). However, there were significant differences in the pathological type, acute abdomen emergency surgery between these two groups (P<0. 05). There was 12 Hp positive cases in mucosalassociated lymphoid tissue (MALT) lymphoma of PGL group (12/19), and 5 Hp positive cases in diffuse large B-cell lymphoma (DLBCL) (5/20). There was significant difference in Hp detection rate of these two pathological types. Hp was not found in PIL group. The Cox multivariate analysis indicated that stage Ⅲ-Ⅳ was the independent adverse factors affecting PGL prognosis (P<0. 05).Conclusions Mainly histological types are DLBCL and MALT lymphoma in PGL, and DLBCL in PIL.PIL predispose to T-cell lymphoma compared with PGL. MALT lymphoma is rare in PIL group. The mainly clinical stage is Ⅲ-Ⅳ both in PGL group and PIL group. Emergency surgery is often needed in PIL because of intussusception or perforation. The prognosis of PGL is correlated with the stage and the prognosis of PIL are correlated with the stage, B symptoms and T cell phenotype.
