Tissue Factor Expression in Colorectal Adenocarcinoma: Association with Angiogenesis and Clinical and Pathological Aspects

Abstract Introduction Tissue factor (TF) expression has been described in various neoplasms and was correlated with angiogenesis and metastases. Objectives To describe TF expression in colorectal cancers, correlating it with microvessel density and clinical and pathological variables. Methods Immunohistochemistry was used to determine TF expression and microvessel density. The Student t-test was used to compare high and low TF expression with microvessel density andwith age. The chi-squared test was used for other comparisons, and Kaplan-Meier curves were used for survival analyses. Res...
