Clinical Significance of TF and VEGF Expressions on Peripheral CD14 Positive Monocytes in Patients with Diffuse Large B Cell Lymphoma / 中国实验血液学杂志

ABSTRACT

OBJECTIVE@#To investigate the clinical significance of tissue factor (TF) and vascular endothelial growth factor (VEGF) expression on peripheral blood CD14 positive monocytes in patients with diffuse large B cell lymphoma (DLBCL).@*METHODS@#The expressions of TF and VEGF on peripheral CD14 monocytes in 41 patients with DLBCL (DLBCL group) before chemotherapy and after 4 chemotherapeutic courses, and in 20 healthy subjects (control group) were detected by flow cytometry respectively, meanwhile, the relationship of the expression of TF and VEGF with international prognostic indexes (IPI) and short-term effects were analysed.@*RESULTS@#The expression levels of TF and VEGF on peripheral CD14 monocytes in DLBCL group were significantly higher than those in control group (P0.05), the survival of patients in group with low expression of TF and VEGF was superior to that in group with high expression of TF and VEGF (P<0.05).@*CONCLUSION@#The paripheral blood CD14 monocytes in DLBCL patients highly express the TF and VEGF, which relate with IPI, therapeutic efficacy and survival, thus the TF and VEGF expression levels are of reference significance for evaluating the therapeutic efficacy and prognosis of patients.
