Злокачественная опухоль нуждается в активной доставке питательных веществ и кислорода для пролиферации и инвазии, что требует создание новой сети сосудов (неоангиогенез). Нормальный и опухолевый ангиогенез контролируется целым рядом про- и антиангиогенных факторов. VEGF является одним из наиболее мощных стимуляторов неоангиогенеза. У больных раком яичников определяется повышенная концентрация VEGF в плазме и опухолевой ткани. Концентрация VEGF в плазме является независимым негативным прогностическим фактором. VEGF и его рецепторы представляются привлекательной мишенью для целевой терапии у больных раком яичников. Для нейтрализации VEGF в настоящее время используется гуманизированное антитело к нему – бевацизумаб (Авастин).
A malignant tumor needs an active delivery of nutrients and oxygen for proliferation and invasion; it stimulates new vasculature (neoangiogenesis). Some pro- and antiangiogenic factors control a process of the angiogenesis. VEGF is the most powerful neoangiogenesis stimulator. Patients with ovarian cancer have high level of VEGF in the blood and tumor tissue. Level of VEGF is an independent negative prognostic factor. VEGF and receptors are very attractive target for the specific therapy in patients with ovarian cancer. Bevacizumab (Avastin) is humanized monoclonal antibody against VEGF.
