Most patients with operable breast cancer now receive postoperative medical treatment in the form of adjuvant chemotherapy, hormone manipulation or both. These additional interventions have led to a significant improvement in disease-free survival and overall survival. Clinical trials suggest that total chemotherapy dose delivered and dose intensity both affect long-term clinical outcomes, yet clinical practice audits conducted in Europe and the USA show that dose reductions and delays are widely applied when haematological toxicities such as neutropenia occur. In order to reduce the risk of neutropenic complications and help deliver chemotherapy planned dose on time, targeted use of recombinant human granulocyte colony-stimulating factor (rHuG-CSF) in breast cancer patients is recommended. The availability of neutropenia risk prediction models and the first once-per-cycle, fixed-dose rHuG-CSF (pegfilgrastim), will allow more patients to benefit from receiving their planned chemotherapy dose on time, and enable the use of new dose-dense chemotherapy strategies in the adjuvant treatment of primary breast cancer. These hold the prospect of further improving chemotherapy treatment outcomes. (C) 2003 Elsevier Ltd. All rights reserved.
