BACKGROUND/AIM: Docetaxel and cyclophosphamide (TC) combination therapy is widely used as adjuvant chemotherapy for early-stage breast cancer and is associated with a high incidence of febrile neutropenia (FN). Granulocyte colony-stimulating factor (G-CSF) is recommended in the primary prevention of febrile neutropenia (FN). This study aimed to evaluate the FN-suppressing effect of G-CSF in patients with breast cancer receiving TC.
PATIENTS AND METHODS: We performed 272 treatment cycles after FN onset in 106 patients with breast cancer receiving TC. We retrospectively evaluated the effect of G-CSF as secondary prophylaxis. The frequency of FN was calculated based on the treatment cycles to adjust for differences in the number of cycles per case and FN occurrence.
RESULTS: FN occurred in 58 cycles (21.3%). The incidence of FN with and without secondary prophylactic G-CSF was 10.1% and 25.9%, respectively (p=0.003). Multivariate analysis showed secondary prophylactic G-CSF administration to be an independent predictor of FN incidence [odds ratio (OR)=0.33, 95% confidence interval (CI)=0.14-0.74, p=0.007].
CONCLUSION: Secondary prophylaxis with G-CSF is recommended for patients with breast cancer undergoing TC chemotherapy to reduce the incidence of FN.
