RESUMEN
Objective To investigate if vascular endothelial growth factor-D(VEGF-D) and endostatin(ES) promote angiogenesis in colorectal cancer(CRC). Methods One hundred and five patients undergoing CRC surgery were enrolled in this study. CRC and normal tissue microarray were produced and measured for VEGF-D and ES by immunohistochemmical staining.Results VEGF-D and ES expression were stronger in CRC tissues than in control normal mucosa. MVD was higher in cancer tissues than in normal ones. ES down-regulated expression was associated with less invasiveness, positive lymph node metastasis, distant metastasis and in cases of early Dukes′ stage, while the expression of VEGF-D in corresponding tissues was on the opposite to ES. MVD increased along with tumor invasion, lymph involvement, distant metastasis and late Dukes′ stage. Conclusions VEGF-D in accord with ES promotes the angiogenesis and progression of CRC.
