Abstrakt: Purpose: Breast cancer is one of the most prevalent malignant diseases in women. The development of dose dense chemotherapy regimens has improved clinical outcomes but has been associated with increased hematological toxicity. Currently there is a paucity of data on the use of lipegfilgrastim in dose dense AC treatment in early breast cancer. The purpose of this study was to assess the use of lipegfilgrastim in the treatment of early breast cancer and to examine the incidence of treatment-related neutropenia during the dose dense AC phase and subsequent paclitaxel treatment.
Methods: This was a single arm, non-interventional, prospective study. The primary endpoint was to determine the rate of neutropenia defined as ANC of < 1.0 × 10 9 /L, during four cycles of dose dense AC with lipegfilgrastim support. The secondary endpoints were the incidence of febrile neutropenia, (temperature > 38 °C and ANC < 1.0 × 10 9 /L), treatment delays, premature treatment cessation and toxicity.
Results: Forty-one participants were included in the study. Of the 160 planned dose dense AC treatments, 157 were administered, and 95% (152/160) of these were given on time. The rate of treatment delay was 5% (95% CI 2.2 to 9.9%) due to infection (4) and mucositis (1). Four (10%) patients developed febrile neutropenia. The most frequently occurring adverse event was grade 1 bone pain.
Conclusion: Lipegfilgrastim is an effective option in the prophylaxis of chemotherapy-induced neutropenia, and its use in everyday anti-cancer treatment can be considered.
