ABSTRACT Women 65 and older ("older women") account for nearly half of all new cases of breast cancer. With the "graying of America" the absolute number of older women diagnosed and undergoing breast cancer treatment will almost double by the year 2030. Treatment guidelines for these older patients include systemic therapy and older women are interested in chemotherapy for even small returns in survival extension. But systemic therapy is not without side effects, and numerous studies have documented cognitive decline after receipt of these agents. Imaging and animal studies confirm that cancer chemotherapy affects brain structure and function. However, very little is actually known about cognitive decline in older patients, because virtually all of the existing research has been conducted in younger patients. Since aging itself is associated with cognitive decline, older patients are likely to be particularly vulnerable to the adverse cognitive effects of systemic therapy. Our preliminary work suggests that this is the case, but this has never been empirically tested. This study will be the first large scale, prospective, controlled investigation to evaluate cognitive changes in older cancer patients. We use the vulnerability model of cancer survivorship to describe systemic therapy effects on cognition over a 12 month period, test associations between cognition and quality of life and to evaluate whether APOE polymorphisms moderate cognitive outcomes. We have assembled a team of oncologists, geriatricians, neurologists, neuro-, cognitive and behavioral psychologists and consumers from Lombardi Comprehensive Cancer Center, Memorial Sloan-Kettering Cancer Center, Boston University and Y- Me (a national consumer advocacy organization). We will enroll 325 newly diagnosed older breast cancer patients and an equal number of non-cancer friend controls. Participants will undergo baseline (pre-systemic therapy) neuropsychological testing and telephone interviews; clinical data will be abstracted from records. Participants will repeat cognitive testing and QOL measures 12 months after baseline. The primary outcome is change in the summary score on tests in the Attention, Working Memory, and Psychomotor Speed Domain. Four additional domains are included as secondary outcomes to assess broader cognitive function and examine differential impact: Language; Executive Functioning; Learning and Memory; Visuospatial. The results of this study will contribute to designing appropriate regimens for older women, developing preventive interventions, informing clinical decision-making about treatment, and guiding second generation studies. Overall, this topic has high research, clinical and public health importance, given the projected growth in the older population, rising incidence with advancing age, trends towards increasing use of systemic therapy in older patients, use of more aggressive dosing regimens, high survival rates, and increasing life expectancy.

抽象的 妇女65岁及以上（“老年妇女”）占所有新乳腺癌病例的一半。与 “美国灰色”的绝对数量被诊断出和接受乳腺癌治疗的老年妇女人数 到2030年将几乎翻一番。这些老年患者的治疗指南包括全身治疗 老年妇女对化学疗法感兴趣，即使是生存延伸的少量回报。但是系统性 治疗并非没有副作用，许多研究记录了收到后认知能力下降 这些代理。成像和动物研究证实，癌症化疗会影响大脑结构和 功能。但是，实际上对老年患者的认知能力下降知之甚少，因为几乎所有 现有的研究是在年轻患者中进行的。由于衰老本身与认知有关 下降，老年患者可能特别容易受到全身性认知不良影响的影响 治疗。我们的初步工作表明情况是这种情况，但这从未经过经验测试。 这项研究将是第一个大规模，前瞻性，对照调查，以评估认知能力变化 老年癌症患者。我们使用癌症生存的脆弱性模型来描述系统治疗 在12个月内对认知的影响，认知和生活质量之间的测试关联以及 评估APOE多态性是否适中认知结果。我们组建了一个团队 肿瘤学家，老年医生，神经科医生，神经，认知和行为心理学家以及来自的消费者 伦巴第综合癌症中心，纪念斯隆 - 凯特林癌症中心，波士顿大学和Y- 我（国家消费者倡导组织）。我们将注册325个新诊断为较老的乳腺癌 患者和相等数量的非癌症朋友对照。参与者将进行基线（系统前 治疗）神经心理学测试和电话访谈；临床数据将从记录中抽象出来。 参与者将在基线后12个月重复认知测​​试和QOL测量。主要结果是 在注意力，工作记忆和心理运动速度域中的测试中的摘要得分更改。 包括四个额外的领域作为次要结果，以评估更广泛的认知功能和 检查差异影响：语言；执行功能；学习和记忆；视觉空间。 这项研究的结果将有助于为老年妇女设计适当的方案 预防干预措施，告知有关治疗的临床决策，并指导第二代 研究。总体而言，鉴于预计的增长，该主题具有很高的研究，临床和公共健康的重要性 在老年人群中，随着年龄的增长的发病率上升，全身治疗的使用趋势 在老年患者中，使用更具侵略性的给药方案，高存活率和预期寿命的提高。
