ABSTRACT
ABSTRACT Objective To assess the incidence of febrile neutropenia without primary granulocyte colony-stimulating factor prophylaxis in patients undergoing chemotherapy with adjuvant docetaxel and cyclophosphamide, and to evaluate the toxicity profile of brand-name docetaxel (Taxotere ® ) and the generic formulation. Methods This retrospective study was conducted using data obtained from electronic medical records of patients treated at a Brazilian cancer center. Patients with breast cancer who underwent adjuvant treatment between January 2016 and June 2019 were selected. Data were analyzed using chi-square and Fisher correlation of variables, and multivariate analyses were adjusted for propensity score. Results A total of 231 patients with a mean age of 55.9 years at the time of treatment were included in the study. The majority (93.9%) had luminal histology, 84.8% were at clinical stage I, and 98.2% had a good performance status. The overall incidence of febrile neutropenia in the study population was 13.4% (31 cases). The use of brand-name docetaxel (Taxotere ® ) was the only factor associated with febrile neutropenia occurrence (OR= 3.55, 95%CI= 1.58-7.94, p=0.002). Conclusion In patients with breast cancer who require treatment with adjuvant docetaxel and cyclophosphamide regimen, the toxicity profile differs between brand-name and generic docetaxel. Regardless of the formulation used, the incidence of febrile neutropenia was less than 20%, which may allow for the omission of primary prophylactic granulocyte colony-stimulating factor use in this setting.
