Neutropenic event incidence in women with early-stage breast cancer receiving neoadjuvant or adjuvant chemotherapy: a retrospective study

The incidence of neutropenic events in this study is relatively low. A higher incidence of neutropenic episodes is observed in patients ≥ 60 years old compared with younger patients, despite lower doses of chemotherapy for the elderly. The use of G-CSF in the elderly, regardless of the dose of chemotherapy, may be needed to decrease the incidence of neutropenia and its consequences. The adverse effects of G-CSF and its cost-effectiveness are important perspectives which should be included in the treatment.
