α-fetoprotein, vascular endothelial growth factor receptor-1 and early recurrence of hepatoma

Figure 3 Patients were classified into four groups according to the level/status of their bone marrow-vascular endothelial growth factor receptor-1 and bone marrow-α-fetoprotein mRNA as follows: group A (n = 23), bone marrow-vascular endothelial growth factor receptor-1/bone marrow-α-fetoprotein mRNA = low/negative; group B (n = 57) high/negative; group C (n = 10) low/positive; group D (n = 24), high/positive. The disease-free survival (DFS) curve of group A was significantly better than that of groups B, C or D (P = 0.0437, P = 0.0325, P = 0.0225).
