Abstract：【Objective 】To analyze the clinical characteristics, survival and prognostic factors of primary gastric diffuse large B-cell lymphoma (PG-DLBCL). 【Methods】The clinical data of 41 patients with PG-DLBCL were retrospectively analyzed. we applied Kaplan-Meier to estimate the survival time of all patients. 【Results】 Among the 41 patients, the OS (overall survival) rate at 1- , 3- , and 5 years were 77.3%, 62.8%, 55.0%, respectively. Patients with surgery alone had very poor diagnosis. In PG-DLBCL patient with over 6 cycles of chemotherapy, there was no significant difference in the survival rate between chemotherapy alone and surgery combined chemotherapy (P>0.05). Patients with more than 6 cycles of chemotherapy had a significantly higher survival rate than patients under chemotherapy for 6 cycles(P＜0.05). The prognosis of R-CHOP chemotherapy was better than CHOP. Univariate analysis showed that B-symptoms, Lugano stage ⅡE~Ⅳ, IPI (International Prognosis Index) score of 3-5 points, peripheral blood NLR ≥ 3.5, high CA125 , and LDH levels were predictors for poor prognosis in patients with PG-DLBCL(P＜0.05). 【Conclusion】B symptoms, Lugano staging of ⅡE~Ⅳ, IPI score of 3~5 points, peripheral blood NLR≥3.5, increased CA125, and elevated LDH level were important influencing factors for poor prognosis of PG-DLBCL(P＜0.05).Chemotherapy-based treatment program is recommended.Chemotherapy regimen of more than 6 cycles and chemotherapy with rituximab can improve the prognosis of patients.
