VEGF-A clinical significance in gastric cancers: immunohistochemical analysis of a wide Italian cohort

Eur J Surg Oncol. 2014 Oct;40(10):1291-8. doi: 10.1016/j.ejso.2014.03.028. Epub 2014 Apr 12.

Abstract

Purpose: The clinical significance of VEGF-A expression in gastric cancer (GC) has been reported with contradicting results. We analyzed the expression and clinical significance of VEGF-A in a wide Italian cohort of GC specimens.

Methods: VEGF-A expression was tested by immunohistochemistry in 507 patients with GC of all clinical stages. The impact of VEGF-A on overall survival (OS) was evaluated in conjunction with clinical and pathological parameters.

Results: In the Italian cohort we studied VEGF-A was not an independent prognostic factor neither at the univariate nor at multivariate analysis.

Conclusions: Although frequently expressed, in our study VEGF-A was not able to discriminate between groups of patients with different risk.

Keywords: Gastric cancer; Immunohistochemistry; Prognostic markers; VEGF-A.
