Abstract. Febrile neutropenia (FN) is a common and potentially fatal complication of anticancer treatment, particularly in patients receiving myelosuppressive chemotherapy. It has been shown that prophylaxis with granulocyte colony-stimulating factor (G-CSF), especially itsThe vast majority of chemotherapy (CHT) regimens used in the treatment of cancer patients is burdened with hematological toxicities that can manifest by impaired cell division of white blood cells, particularly neutrophils. Effectiveness of myelosuppressive CHT is often limited by the dose-dependent toxicity, which determines the possibility of administration of additional treatment cycles (1). The risk of infectious complications significantly increases along with the decline of granulocytes below the critical level (absolute neutrophil count <500 cells/mm 3 ). Severe neutropenia (grade 3 and 4), lasting for more than three days, causes a linear increase in the risk of febrile neutropenia (FN) (10% per day). FN is a common and potentially fatal complication of anticancer treatment (2, 3). The administration of granulocyte colony-stimulating factor (G-CSF) recombinant forms results in a reduction of neutropenia and its occurrence. It has been shown that prophylaxis with G-CSF, especially its pegylated forms, significantly reduces the incidence of FN, the likelihood of chemotherapy dose intensity reduction and, also, the number of hospitalizations due to FN (4-10). Lipegfilgrastim is the newest glycopegylated modification of the original molecule filgrastim, which shows maximal structural conformity with the endogenous G-CSF. The glycopegylated form enables application of filgrastim once during the cycle of chemotherapy (11,12). This review discusses several interesting results of interim analysis from non-interventional studies evaluating the safety and efficacy of lipegfilgrastim in routine clinical practice that have been recently published.
The Role of Lipegfilgrastim in Routine Clinical PracticeOne of the most interesting results in FN prophylaxis comes from the recently published interim analysis of noninterventional clinical trial LEOS (a prospective pan-European non-interventional study evaluating the effectiveness of lipegfilgrastim in clinical practice for the prophylaxis of 303 This article is freely accessible online.Correspondence to:
