ABSTRACT
Objective To understand the clinical characteristics and treatment outcomes of primary gastrointestinal non-Hodgkin lymphomas (PGINHL) and analyze the differences between T-cell and B-cell lymphomas.Methods.The characteristics of 51 PGINHL patients were analyzed regarding to their clinical manifestations,diagnosis,treatments and outcomes.Results 51 cases of PGINHL meeting the WHO(2008) criteria were identified.The median age of the patients at the time of diagnosis was 56 years old and the male ∶ female ratio was 1.44∶1,35 cases (68.7 ％) had B-lineage and 16 cases (31.3 ％) had T-cell lineage lymphomas.Compared to those with B-cell lymphoma,patients with T-cell lymphoma presented with a greater incidence of such symptoms as hematochezia,diarrhea and night sweating (P ＜ 0.05).After eliminating MALT lymphoma,prognosis of T-cell lymphoma and B-cell lymphoma had no significant difference.Conclusion In PGINHL cases,B-cell lymphomas appeare to be more common and have better prognosis than T-cell lymphomas.
