The myelodysplastic syndromes (MDS) are a group of disorders characterized by dysplastic hemopoiesis and an increased risk of leukemic transformation. The process of angiogenesis has been implicated in the pathogenesis and evolution of MDS. In this study the proliferative activity and extent of angiogenesis was examined in bone marrow samples from 54 patients with MDS in relation to clinicopathologic features. Cellular proliferation and microvascular density (MVD) were examined immunohistochemically, using the monoclonal antibody MIB-1 (Ki-67) and an anti-CD34 monoclonal antibody respectively. Serum concentrations of interleukin-6 (IL-6) were measured by ELISA. The results showed that the MIB-1 Labeling Index (MIB-1 LI), MVD and IL-6 increased significantly with advancing severity of disease. Among the MDS-FAB subtypes, MIB-1 LI, MVD and IL-6 were significantly higher in RAEB-t, RAEB and CMML in comparison to RA and RARS (p < 0.0001 in all cases). Similarly, MIB-1 and MVD were increased in patients with score 3 in comparison to scores 0 and 1 in the IPSS system (p < 0.05). All parameters studied were significantly higher in patients versus controls. We conclude that cellular proliferative activity and angiogenesis are associated with disease progression in MDS patients.
