Immunohistochemical evaluation of the tumor neoangiogenesis as a prognostic factor for gastric cancers.

Abstract

Our results prove the major correlation between the VEGF expression and the 5-year survival rate of the patients with gastric cancer, the survival rate for the carcinomas with VEGF +~++ being significantly lower than for the VEGF negative ones (12.5% vs. 23.8%) (p=0.027983 S). Our study proves a tight correlation between the VEGF expression and the MVD (p=0.03986 S), these factors playing an important role in the tumoral biologic conduct, in the progression and the prognostic.
