Polymorphisms rs4673 and rs28714259 in predicting anthracycline-mediated cardiotoxicity in patients with breast cancer.

Introduction: Against the background of significant progress in anticancer therapy, which makes it possible to improve the quality of life and life expectancy of patients with cancer, anthracycline antibio-tics retain their relevance, both for scientific research and for clinical practice. However, the therapeutic efficacy of anthracyclines is associated with the development of various complications, among which the most common is cardiotoxicity. Our study was dedicated to searching for possible associations between rs4673 and rs28714259 single nucleotide polymorphisms (SNPs) and the risk of cardiotoxicity in breast cancer patients who underwent anthracycline-containing chemotherapy.
