Abstract

Introduction

Adjuvant docetaxel-based chemotherapy is frequently used in the treatment of operable early breast cancer (EBC). This study investigated patterns of docetaxel use in patients with EBC in real-world clinical practice in China.

Methods

This was a multicenter, prospective, observational study of Chinese women with operable breast cancer in tier 1 non-oncology-specific hospitals and other city hospitals in China. Adult Chinese female patients (≥ 18 years) with newly diagnosed breast cancer who underwent surgery and received docetaxel-containing adjuvant chemotherapy were eligible for inclusion. The primary end point of the study was to assess patterns of docetaxel use for adjuvant therapy in Chinese clinical practice. Secondary end points included factors associated with treatment selection, patterns of G-CSF use and safety.

Results

In total, 502 patients were enrolled, 475 of whom were included in the analysis. The results showed that 31.6% of patients received docetaxel and anthracyclines in combination, 47.2% received docetaxel and anthracyclines sequentially, 18.5% received docetaxel and other medication either in combination or sequentially and 2.7% received ‘other’ chemotherapy regimens. Factors influencing selection of docetaxel/anthracycline in combination versus sequentially included age, breast cancer subgroup, PR status, and preoperative neoadjuvant chemotherapy. A total of 258 (54.3%), 35 (7.4%), and 108 (22.7%) patients received G-CSF as primary prevention, secondary prevention and treatment, respectively. Treatment-emergent adverse events (TEAEs) occurred in 54.5% (259) of patients, and the most frequently reported TEAEs (≥ 5% of patients) included bone marrow failure (10.1%), granulocytopenia (9.9%), nausea (8.8%) and vomiting (6.9%). Neutropenia and febrile neutropenia were reported by 10 and 12 patients, respectively.

Conclusion

Docetaxel for adjuvant chemotherapy of operable EBC in China was most commonly given in combination or sequentially with anthracyclines. The study also showed that in China G-CSF is most frequently used as primary prophylactic, and no unexpected safety events were observed during docetaxel treatment.
