Review of the value of colony stimulating factors for prophylaxis of febrile neutropenic episodes in adult patients treated for haematological malignancies

Abstract

Chemotherapy-induced neutropenia is a major dose-limiting toxicity of systemic cancer chemotherapy that can lead to fever and infection, requiring prompt analysis and in-patient treatment with broad-spectrum antibiotics. Complicated neutropenia may lead to reduction and/or delay of systemic anti-cancer treatment, which may compromise outcome. Haematopoietic growth factors have the ability to augment haematopoietic cell cycling and are used to facilitate more dose-intense treatments and to decrease treatment-related complications. This review focuses on randomised trials that investigated the use of colony-stimulating factors (CSF) to prevent treatment-related febrile complications in haematological malignancies in (younger) adult patients. In general, these studies demonstrated that CSF reduced the duration of severe neutropenia but not always its febrile complications; therefore inconsistent results regarding clinically relevant reduction of hospitalisation, duration of therapeutic antibiotics, infection-related or disease-related mortality and economic effects were reported. Current developments in treatment of haematological malignancies will pose new challenges as a shift in infectious pathogens can be expected. © 2007 The Authors.
