Abstract
Purpose: Angiogenesis is one of the key steps in solid tumor growth and metastasis. We investigated the prognostic significance of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1α (HIF-1α
) expressions as markers of angiogenesis in colon cancer.
Methods: We retrospectively reviewed the medical records of 78 patients with colon or rectal cancer who underwent a surgical resection at Soonchunhyang University Hospital from January 2000 to December 2001, and we evaluated the expression of VEGF and HIF-1α in archival tumor tissues by using immunohistochemistry. We recorded the clinical and the pathological characteristics of the patients and analyzed their survival outcomes.
Results: Thirty-four (34) patients were male, and the mean age of all the patients was 66.7 years. HIF-1α
and VEGF were positive in 56% (44 patients) and 53% (42 patients) of the tumors, respectively. HIF-1? expression was significantly associated with several pathological parameters, such as TNM stage (P=0.001), lymph node metastasis (P=0.001). HIF-1α expression was also associated with VEGF expression (P=0.032). The survival of patients with HIF-1α
expression was worse than that of patients with no HIF-1α expression (P=0.036). However, VEGF expression was not associated with other pathological characteristics.
Conclusions: We suggest that, in cases of colorectal cancer, HIF-1α expression may be associated with expression of VEGF, progression of tumors, and poor prognosis.
