Objective To study the expression of p53 and vascular endothelial growth factor (VEGF) and its correlation with hematogenous metastasis in colorectal cancer. MethodsAvidinbiotin complex method was used to study the expression of p53 and VEGF in 79 cases of colorectal cancer.ResultsThe positive rates of p53 and VEGF were 48.1% and 58.2% respectively in 79 cases of colorectal cancer. p53 and VEGF expression were identical in 49 (62.0%) cases. There was significant association between p53 or VEGF expression and venous invasion or hematogenous metastasis (P＜0.05). The incidence of hematogenous metastasis in the p53（＋）/VEGF（＋） subgroup was 66.7% and was significantly higher than that in the p53（－）/VEGF（－） or p53（＋）/VEGF（－） subgroup （P＜0.01）. Neither synchronous nor metachronous hematogenous metastasis were found in the p53（－）/VEGF（－） subgroup.Conclusion The combination of p53 and VEGF expression is an important predictor for hematogenous metastasis in patients with colorectal cancer.
