Abstract:Objective To explore the incidence and risk factors for venous thromboembolism(VTE)in 145 patients with diffuse large B-cell lymphoma(DLBCL).Methods Totally 145 DLBCL patients admitted to our hospital from May 2016 to August 2019 were selected and divided into a VTE group(n=22)and a non-VTE group(n=123)as the results in ultrasonography for VTE.Multivariate Logistic regression was used to analyze the risk factors for VTE in DLBCL patients,as well as the difference of recurrence rate,recurrence-free survival rate,and overall survival rate between groups.Results The independent risk factors for VTE were intravenous catheterization,non-complete remission(non-CR)after 3-4 courses of chemotherapy,D-dimer level≥1.44μg/ml(OR=5.143,9.000,16.514,P<0.05).But performance status(PS)score≥2 was considered a protective factor(OR=0.170,P<0.05);there was no significant difference in recurrence rate,recurrence-free survival rate,and overall survival rate between groups(P>0.05).Conclusion Independent risk factors for VTE in DLBCL patients were Intravenous catheterization,non-CR after 3-4 courses of chemotherapy,D-dimer≥1.44μg/ml,and protective factor for VTE is PS score≥2.
