Contribution of glycosylated recombinant human granulocyte colony-stimulating factor (lenograstim) use in current cancer treatment: review of clinical data

Abstract

Importance of the field: Granulocyte colony-stimulating factors (G-CSFs) such as lenograstim have improved the management of cancer patient treatments for 15 years. Their use in preventing chemotherapy-induced febrile neutropenia and for progenitor-cell transplantation has been evaluated. Although the main indications are nowadays defined in academic guidelines, some changes in traditional G-CSF use are being induced by the emergence of new chemotherapy schedules and new drugs.

Areas covered in this review: Analyzing publications on G-CSFs and lenograstim identified in the PubMed database from 1985 to date, we summarise pharmacological data and clinical trials on lenograstim and discuss its effects and limits in current treatment regimens.

What the reader will gain: Lenograstim is a glycosylated form of recombinant human G-CSF, more similar to the endogenous cytokine. Clinical trials have proven its efficacy for preventing chemotherapy-induced neutropenia and for progenitor-cell transplantation, almost similar to filgrastim. Its benefit is compelling in some well-defined settings (highly myelosuppressive chemotherapy, advanced cancer, high-risk patients).

Take home message: If usual indications are well defined nowadays, further investigations are still needed to better define optimal use (optimal time to start, treatment duration) and effects on quality of life. In addition, since new strategies for cancer management are emerging, such as oral chemotherapy or targeted therapies, there is a need for clinical data to define lenograstim use in these recent settings.
