Despite the development of highly effective antitumor therapies over the past two decades (e.g., targeted therapy, immunotherapy), chemotherapy regimens including anthracyclines, taxanes, and cyclophosphamide continue to represent a fundamental component of treatment algorithms for early breast cancer, particularly in human epidermal growth factor receptor 2 (HER2)-positive and triple-negative breast cancer (TNBC). While the cardiotoxicity of anthracyclines is well established and routinely monitored by echocardiography, changes in lipid profiles induced by cytotoxic chemotherapy have primarily been reported in retrospective studies with heterogeneous patient populations and measurement protocols.
This prospective, single-center study was designed to evaluate changes in lipid parameters in patients with early-stage breast cancer undergoing neoadjuvant or adjuvant chemotherapy with doxorubicin, cyclophosphamide, and paclitaxel.
