Abstract:
Background:Angiogenesis plays a critical role in tumor growth and metastasis. AGGF1,a new member of angiogenic factors,has been shown to be aberrantly expressed in a variety of malignant tumors. Aims:To investigate the correlation of AGGF1 expression with prognosis of patients with colon cancer. Methods:Eighty colon cancer patients undergoing surgical operation from Jan. 2010 to Dec. 2012 at Xi’an First Hospital were recruited. Immunohistochemistry was performed to evaluate the expression of AGGF1 in cancerous and paired paracancerous tissues. The correlations of AGGF1 expression in cancerous tissue with clinicopathological characteristics and prognosis were analyzed. Cox regression model was used to identify the prognostic factors of colon cancer. Results:AGGF1 expression was significantly higher in colon cancer tissue than in paracancerous tissue (67. 5% vs. 32. 5%,P＜0. 05),and was correlated with tumor differentiation,lymph node metastasis,vascular/lymphatic infiltration and TNM stage (P＜0. 05). Kaplan-Meier survival analysis showed that high AGGF1 expression was correlated with decrease of survival rate in colon cancer patients (P ＜0. 05). Univariate and multivariate analyses identified AGGF1 as a prognostic factor of patients with colon cancer (OR＝2. 09,95% CI:1. 67-4. 45,P＝0. 011;OR ＝1. 98,95% CI:1. 72-4. 59,P ＝0. 000 ). Conclusions:Angiogenic factor AGGF1 is up-regulated and correlated with tumor metastasis and unfavorable prognosis in patients with colon cancer. It might be a potential prognostic indicator and deserves further study.
