... ignant tumors. This dictates the need for widespread use of preventive measures aimed at minimizing the risk of FN in cancer patients receiving cytotoxic chemotherapy. Numerous studies have shown that prophylactic use of granulocyte colony-stimulating factors can significantly reduce the duration of profound neutropenia, the incidence of FN and - most importantly - related mortality. This article is devoted to a review of modern approaches to the use of granulocyte colony-stimulating factors (G-CSF) in the context of the current system of cancer care financing - clinical and statistical groups (CSGs) on the territory of the Russian Federation. Various aspects of the use of drugs of this class to prevent febrile neutropenia in the context of its primary and secondary prevention, the rules of G-CSF use, current data on the effectiveness and feasibility of use in different clinical scenarios are considered in detail. The advantages of modern long-acting dosage forms of G-CSF and their place in modern clinical practice are considered.
