Brief Summary

Previous studies have shown differences in the effects of different endocrine drugs on blood lipids in breast cancer, and dyslipidaemia is a major risk factor for cardiovascular disease, and it has been previously reported that the leading cause of death in postmenopausal patients with breast cancer is cardiovascular disease, but the effects of endocrine drug therapy on blood lipids in young breast cancer patients (age ≤40) are not clear. Previously, our group conducted a preliminary retrospective analysis of young patients on endocrine therapy and found that dyslipidaemia was also a common adverse effect of treatment in young breast cancer patients; therefore, dyslipidaemia induced by antineoplastic therapy not only occurs in postmenopausal patients, but is also prevalent in premenopausal and even younger patients. Therefore, this study intends to evaluate the effects of different treatment regimens on lipids in early-stage young breast cancer patients and to explore the optimal timing of lipid-lowering drug interventions to provide a basis for clinical practice.
