简要总结
RATIONALE: Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
PURPOSE: This phase II trial is studying the side effects of trastuzumab and to see how well it works in treating older women with early-stage breast cancer.
详细描述
OBJECTIVES:
Primary
- To evaluate the 3-year cumulative incidence of cardiac events in women 60 years and older with HER2-positive breast cancer who receive single agent trastuzumab (Herceptin®) in the adjuvant setting.
Secondary
- To evaluate the 1-year cumulative incidence of asymptomatic cardiac left ventricular dysfunction in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting.
- To evaluate long-term cardiac toxicity (5-year cumulative incidence of cardiac events) in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting.
- To assess the relation between physiologic markers of chronic heart failure and trastuzumab-related cardiac dysfunction in women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab.
- To assess the relation between pro-inflammatory cytokines and trastuzumab-related cardiac dysfunction in women 60 years and older with Her2-positive breast cancer.
- To determine the effect of this drug on the health-related quality of life and functional, cognitive, and mental status of women 60 years and older with Her2-positive breast cancer.
- To determine the 5-year disease-free survival and overall survival of women 60 years and older with Her2-positive breast cancer who receive single agent trastuzumab in the adjuvant setting.
