We determined the marrow levels of seven molecules associated with angiogenesis in 52 AML patients before chemotherapy and 20 healthy controls: VEGF-A, VEGF/ PlGF, VEGF-C, VEGF-D, Ang-1, Ang-2, and Tie-2. All the molecules were quantified using enzyme-linked immunosorbent assay ( ELISA). Comparing to normal controls, the marrow levels of VEGF/PlGF, Ang- 2, and Tie-2 were significantly higher, and those of VEGF-C and Ang -1 were significantly lower in the AML patients (P < 0.001). A total of 31 patients were further subjected to survival analysis. Patients with lower Tie-2 (< 26 ng ml(-1)) and Ang -2 levels (< 4500 pg ml(-1)) displayed a survival advantage( P = 0.037 and 0.042, respectively), same as patients with higher VEGF/ PlGF (>= 1 pg ml(-1)) and VEGF-D levels (>= 350 pg ml(-1 )) (P = 0.020 and 0.016, respectively). An angio- index ((Ang-2 x Tie- 2)/ ( VEGF/ PlGF x VEGF-D)) was established and multivariate Cox regression analysis revealed that patients with higher angio-index values (>= 50 ) displayed poor prognosis ( hazard ratio 5.91, 95% confidence interval 1.99 -17.56; P 0.001). The angio-index is closely associated with the clinical outcome of AML patients and may be valuable in disease prognosis. |
