Objective To explore the therapeutic effects of rituximab+cyclophosphamide+doxorubicin+vincristine+prednisone(R-CHOP)in the treatment of elderly patients with diffuse large B-cell lymphoma(DLBCL)and the factors related to prognosis.Methods A total of 107 elderly DLBCL patients admitted from January 2018 to March 2023 were retrospectively en-rolled as the research subjects.The short-term efficacy of R-CHOP and the prognosis of patients were statistically analyzed.Mult-ivariate regression analysis was used to analyze the related factors affecting the curative effect and prognosis.Results In the 107 elderly patients with DLBCL,ORR was 77.57%(83/107)after three courses of treatment,including 44 ones with complete re-mission(41.12%)and 39 ones with partial remission(36.45%).As of March 2024,31 patients(28.97%)had died from dis-ease progression or treatment-related adverse events during follow-up.Multiple classification ordered logistic regression analysis showed that age>70 years old(OR=2.628,P=0.020),Ann Arbor stage Ⅲ to Ⅳ(OR=4.004,P=0.003),bone marrow in-vasion(OR=3.749,P=0.002),and elevated LDH(OR=3.616,P=0.002),and elevated β2-MG(OR=3.137,P=0.010)were independent risk factors for the efficacy of R-CHOP treatment in elderly DLBCL patients(P<0.05).Binary logistic analy-sis showed that age>70 years old(OR=5.427,P=0.006),activated B-cell-like subtype(OR=5.777,P=0.014),Ann Ar-bor stage Ⅲ to Ⅳ(OR=3.465,P=0.026),bone marrow invasion(OR=3.792,P=0.023)and no response after treat-ment(OR=5.688,P=0.012)were independent risk factors affecting the prognosis of elderly DLBCL patients after R-CHOP treatment(P<0.05).Conclusion Age>70 years old,activated B-cell-like subtype,Ann Arbor stage Ⅲ to Ⅳ,and non-re-sponse after treatment are independent risk factors affecting the prognosis of elderly DLBCL patients after R-CHOP treatment.Risk stratification based on these factors should be performed clinically to improve the prognosis of patients.
