Abstract:
Objective To analyze the clinical characteristics and prognostic factors in patients with primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL),and to improve the diagnosis and treatment of PGI-DLBCL.Methods Retrospective analysis was conducted in 51 cases of PGI-DLBCL between January 2009 and August 2013.The data included clinical manifestations,pathological features,treatment regimens and prognosis.Results 51 patients included 31 males and 20 females,the range of ages was from 16 to 80 years old,median age was 48 years old.The major clinical presentation were abdominal pain,abdominal distension,abdominal mass,nausea and vomiting,abdominal mass.The occurrences in stomach,small intestine,colon,rectum and multiple involvement were 56.86 ％,29.41％,7.84 ％,1.90 ％ and 3.92 ％ respectively.The mass bigger than 10 cm was found in 13 cases (25.49 ％).47.06 ％ (24/51) of the cases belonged to the GCB subtype and 52.94 ％ (27/51) belonged to the non-GCB subtype.There was no significant impact of lymphoma cell origin,disease distribution (stomach or intestinal) and mass on prognosis of lymphoma treatment.The univariate analysis revealed that the patients with Lugano stage Ⅳ,increased level of serum lactate dehydrogenase (LDH),modified-international prognosis index (modified IPI) 3-5 and increased level of CA125 had poor prognosis (all P ＜ 0.05).There was no difference of survival rate between patients treated with rituximab plus chemotherapy and single CHOP like therapy.Surgery plus postoperative chemotherapy significantly improved survival of patients treated with simple chemotherapy (P ＞ 0.05).Conclusion The clinical Lugano stage,IPI score,increased LDH and CA125 are important prognostic factors of PGI-DLBCL.
