项目摘要
DESCRIPTION (provided by applicant): Cognitive decline is one of the most feared consequences of aging among older adults and even minor changes in cognitive function can seriously impact function, ability to live independently, and quality of life. The trajectory of cognitive change with normal aging is influenced by factors including genetics, cognitive reserve, lifestyle, frailty, and comorbid medical conditions. Although there are compelling data suggesting a relationship between cancer, cancer therapy, and cognitive impairment the vast majority of these studies have focused on younger patients (<65 years old) and few studies have focused on 5+ year survivors. However, the majority of cancer survivors are older adults. Furthermore, those who were treated at an older age may be more vulnerable to cognitive decline because factors that influence normal cognitive aging may interact with cancer treatments to increase vulnerability. The objective of this application is to unite the fields of geriatrics, neuropsychology, oncology, and genetics to study the prevalence and trajectory of cognitive impairment in a cohort of older, long-term (5-15 years) survivors of breast cancer and matched healthy controls. Using a prospective, longitudinal study design, we will pursue the following specific aims while controlling for comorbidity and frailty: Aim 1: Examine the association of APOE status, smoking history, and therapeutic exposures on the cognitive performance among older breast cancer survivors compared to controls (age-, race- and education-matched) Aim 2: Utilize Growth Mixture Modeling techniques to determine trajectories of longitudinal change in cognitive function among older breast cancer survivors and controls (age-, race- and education-matched): Aim 3: Explore associations among cognitive reserve, APOE, smoking history and therapeutic exposures on cognitive functioning at study entry and the pattern of longitudinal change. This study is significant because it will fill a major gap in knowledge regarding the factors that increase risk for cognitive decline in older breast cancer survivors. These data are critical in order to weigh the risks and benefits of cancer treatment in the growing aging population. This study is innovative because it will examine the interactions of therapeutic exposures, genetic polymorphisms, and smoking history in predicting differences in cognitive performance between breast cancer survivors and controls controlling for burden of comorbidity and frailty. Furthermore, the longitudinal design will inform whether the trajectory of
cognitive change for cancer survivors parallels healthy controls (phase shift hypothesis) or demonstrates a steeper slope (accelerated aging hypothesis). These data will serve as a foundation to identify older breast cancer survivors at risk for cognitive impairment and guide the
development of rationale interventions to decrease this risk, with the ultimate goal of preserving the cognitive function and well-being of older survivors of cancer.
描述(由申请人提供):认知能力下降是老年人衰老最担心的后果之一,甚至认知功能的较小变化都会严重影响功能,独立生活和生活质量。正常衰老的认知变化轨迹受遗传学,认知储备,生活方式,脆弱和合并症的因素的影响。尽管有令人信服的数据表明癌症,癌症治疗和认知障碍之间存在关系,但这些研究中的绝大多数都集中在年轻患者(<65岁)上,很少有研究集中于5年以上的幸存者。但是,大多数癌症幸存者是老年人。此外,那些在年龄较大的人可能更容易受到认知下降的影响,因为影响正常认知衰老的因素可能会与癌症治疗相互作用以增加脆弱性。 该应用的目的是将老年医学,神经心理学,肿瘤学和遗传学的领域团结起来,以研究认知障碍的患病率和轨迹在乳腺癌的长期长期(5 - 15年)中的同类中,并与健康对照相匹配。使用前瞻性的纵向研究设计,我们将在控制合并症和脆弱的同时追求以下特定目标:目标1:检查APOE状态,吸烟史,吸烟史以及对较旧的乳腺癌幸存者在对照组(年龄,种族和教育匹配的AIM 2:使用较长的成长方式)中的较旧的乳腺癌幸存者之间的认知性能的治疗性暴露的相关性,以确定较长的成长方式。乳腺癌幸存者和对照(年龄,种族和教育匹配):目标3:探索认知储备,APOE,吸烟史和治疗性暴露于研究入学时认知功能以及纵向变化模式的关联。 这项研究很重要,因为它将填补有关增加乳腺癌幸存者认知风险下降风险的因素的主要差距。这些数据对于在不断增长的衰老人群中权衡癌症治疗的风险和益处至关重要。这项研究具有创新性,因为它将检查治疗性暴露,遗传多态性和吸烟史的相互作用,以预测乳腺癌幸存者之间认知表现的差异以及控制合并症和脆弱负担的控制。此外,纵向设计将告知
癌症幸存者的认知变化与健康对照(相位移位假设)相似或表现出陡峭的斜率(加速老化假设)。这些数据将成为识别有认知障碍风险的老年乳腺癌幸存者的基础,并指导
开发理由干预措施以降低这种风险,其最终目标是保留癌症老年幸存者的认知功能和福祉。
