Background/aim: despite the rapidly accumulating histopathological data reporting differences in the expression of members of the angiopoietin family on the surface of various normal and tumour cells, data for these growth factors in plasma from cancer patients, including colon cancer, are scarce. The aims of the present study were to measure the plasma concentrations of Ang-1, Ang-2 and Tie-2 in colon cancer patients, and to assess the correlation between the concentrations of these factors and the stage of the tumor.
Patients And Methods: the study cohort included 36 patients (18 male, 18 female) with colon cancer (mean age 52.
