Immunopathogenetic mechanisms of skin toxic response of antitumor therapy with mul-tikinase of angiogenesis inhibitors

The violation of the angiogenesis is associated with pathogenesis of many diseases, but especially pronounced pathological angiogenesis underlies the growth of tumors and metastasis. The physiological control of the angiogenesis is carried out by many growth factors, one main factor — the vascular endothelial growth factor (VEGF), realizing their effects by receptors — proteinkinases. The target therapy of various neoplastic diseases, based on the suppression of angiogenesis, aimed at blockade of receptors for VEGF and other pro-angiogenic growth factors. However, the medicine blockade of receptors for growth factors and suppression of tumor angiogenesis leads to inappropriate exposure are the main cells of the dermis — fibroblasts. As a result of changing the regulatory mechanisms of inhibition of the physiological renewal of epidermis, suppression of angiogenesis and repair when damaged skin there are various skin toxic reactions that are dependent on receptor targets of angiogenesis inhibitors. The study of the mechanisms of adverse events of targeted therapy is an important way of oncoimmunology and dermatology, which will further help to determine the optimal scheme of correction of dermal toxicity and maximize the effectiveness of the antitumor therapy.
