Clinical relevance of vascular endothelial growth factor-A in colorectal cancer.

Purpose: To study the expression status and clinical relevance of vascular endothelial growth factor-A (VEGF-A) in colorectal cancer (CRC) tissues.

Experimental Design: VEGF-A expression was investigated by immunohistochemistry in 89 cases with CRC. Some demographic and histopathological variables were compared with VEGF-A expression to determine the prognostic significance in CRC.
