Abstract

The aim of the present study was to investigate the prognostic value of vascular endothelial growth factor (VEGF) and its receptor, fms‑related tyrosine kinase‑1 (FLT‑1), in patients with colorectal cancer. An immunohistochemical approach was used to detect the protein expression of VEGF and FLT‑1 in 90 patients with colorectal cancer. The impact of VEGF and FLT‑1 tumor cell expression, in addition to other factors, on overall survival (OS) was retrospectively assessed in 90 patients. Multivariate analysis was performed in order to determine the prognostic significance of the factors. The positive expression rate of VEGF in the colorectal cancer tissues was 62.2% (56/90). The positive expression rate of FLT‑1 in colorectal cancer tissues was 48.9% (44/90). The results of the log‑rank test revealed that improved OS rates were significantly associated with the absence of VEGF expression (P<0.0001). By contrast, FLT‑1 expression had no significant impact on OS (P=0.289). Upon multivariate analysis, VEGF expression (P=0.038) and clinical stage (P=0.021) maintained significance. VEGF expression proved to be an independent negative predictor of OS in patients with colorectal cancer. Conversely, FLT‑1 expression demonstrated no impact on OS.
