Objective:
To investigate the expressions of stromal cell-derived factor (CXCL12), stromal cell-derived factor receptor (CXCR4), vascular endothelial growth factor (VEGF) and microvessel density (MVD) in bone marrow microsputum of patients with multiple myeloma (MM) and their correlation with the prognosis.
Methods:
The expressions of CXCL12, CXCR4, VEGF and MVD in bone marrow microtubules of 57 newly diagnosed MM patients and 26 normal bone marrow samples were detected by immunohistochemistry. The rank sum test was used to compare the differences between the two groups. The clinical data of the patients were collected to analyze the correlation between the indicators of the MM group and the prognosis.
Results:
The expressions of CXCL12, CXCR4, VEGF and MVD in the bone marrow biopsy of the patients in MM group were significantly higher than those in the normal control group (P＜0.05). The expressions levels of CXCL12, CXCR4, VEGF and MVD were in the bone marrow of the patients in MM group were correlated with the ISS stage, risk stratification and the proportion of plasma cells in the bone marrow (P＜0.05). Univariate analysis showed that age, ISS stage, risk stratification, plasma cell ratio, expressions of CXCL12, CXCR4, VEGF, and MVD associated with the prognosis of patients with MM (P＜0.05). Multivariate analysis found that expressions of CXCR4, VEGF, MVD, age, and plasma cell ratio were independent prognostic factors.
Conclusion:
The expressions of CXCL12, CXCR4, VEGF and MVD are increase in the bone marrow of patients with multiple myeloma, and their expressions levels are associate with the occurrence and development of multiple myeloma, and their high expression may indicate a poor prognosis.
