Abstract

Angiogenesis is a process of new blood vessels creating based on existing already vascularisation. This composed and multistage mechanism, which is responsible for growth of the tissues and organs, plays a crucial role in neoplasia. The exact role of particular cells, cytokines and extracellular matrix in cancerogenesis is still discussing. An identification of it is the key to searching the antiangiogenic substances breaking simultaneously neoplastic proliferation. THE AIM OF THE STUDY was to compare the angiopoietin-1(Ang-1), angiopoietin-2 (Ang-2) and Tie-2 receptor (rec. Tie-2) concentrations in the serum of colorectal cancer patients with concentrations of these factors in the serum of healthy people. Moreover the aim of the study was to assess the correlation between the concentrations of these factors and stage of clinical neoplasm progression. The study included 35 patients hospitalized in the Department of General Surgery due to confirmed by histopatological examination colorectal cancer, between 2006 to 2007. The group of examined patients consisted of 9 women and 26 men with ages between 39 to 81 (average 67.20+/-8.85). The control group consisted of 11 healthy people. The examinations relied on the 10 ml of blood sa...Continue Reading
