Angiogenesis is a dynamic process which leads to a development of cancer and metastases. The most recognized and dominant prognostic factor is vascular endothelial growth factor (VEGF) and its receptors. VEGF was identyfied in 1989. There are three receptors for VEGF: VEGFR1 (VEGF receptor 1) and VEGFR2 that play the role in angiogenesis and development of ascites, and VEGFR3 is critical for lymphangiogenesis. There is bevacizumab--a new drug, monoclonal antibody that can block connection VEGF to its receptors. The first notification of activity of bevacizumab in ovarian cancer was in 2005. The aim of the article is to show some clinical trials in ovarian cancer and their results. The bevacizumab was registered in November 2011 in first line with standard chemotherapy in ovarian cancer. There is a new weapon against this disease.
