简要总结
The purpose of this study is to evaluate the prevalence of (sub)clinical cardiovascular disease, cardiovascular risk factors and metabolic abnormalities among long-term breast cancer survivors treated with or without anthracyclines in order to identify patients at increased risk of developing cardiovascular disease.
详细描述
Rationale: Breast cancer (BC) incidence is increasing, while mortality from BC is decreasing. Since the life expectancy of BC patients is improving, the evaluation of treatment-associated cardiovascular disease (CVD) in BC survivors is becoming increasingly important. An excess risk of CVD, mainly due to coronary heart disease (CHD), has been observed after radiotherapy (RT) as administered in the 1960s-1980s. Anthracycline-containing CT and trastuzumab are known to induce cardiotoxicity, especially congestive heart failure (CHF). However, the long-term risks of CVD after anthracycline-containing CT, trastuzumab, hormonal therapy (HT) and contemporary RT techniques have hardly been examined. Furthermore, the potential interaction of these treatment modalities has not been well addressed, and there is limited knowledge about the contribution of classic cardiovascular risk factors and the metabolic syndrome to risk and severity of treatment-associated CVD in BC survivors.
Objectives: • to evaluate the prevalence of (sub)clinical CVD, cardiovascular risk factors and metabolic abnormalities among BC survivors treated with and without anthracyclines in two groups at (a) 5 - 7 years and (b) 10 - 12 years after diagnosis;
• to prospectively evaluate changes in prevalence of (sub)clinical CVD, cardiovascular risk factors and metabolic abnormalities after two years in the same patients.
Secondary objectives are to evaluate the predictive role of newly developed markers for CVD and to evaluate the effects of other BC treatment modalities, psychosocial outcomes, endocrine function and menopausal status on the risk of developing (sub)clinical CVD.
Study design: multicenter (AVL and UMCG) cross-sectional cohort study with prospective monitoring of the same cohort.
