Expression of CXCR4 in group A and group B. A Expression level of CXCR4 in group A and group B (P>0.05); B Expression of CXCR4 increased with the illness of patients in group A in stages II, III, and IV, and the relative expression of CXCR4 increased accordingly; C Spearman correlation analysis showed that the relative expression of CXCR4 was positively correlated with epithelial ovarian cancer staging (P<0.001). D SDF-1 and CXCR4 were positively correlated in epithelial ovarian cancer staging (P<0.001)
