项目摘要

Abstract Treatment for children with cancer has progressed over the past four decades so that, today, over 80% of children diagnosed with a malignancy will become long-term survivors. Currently, there are over 350,000 survivors of childhood cancer living in the United States; nearly 250,000 of these individuals are younger than age 40 years. Unfortunately, treatment for childhood cancer continues to require agents designed to destroy malignant cell lines, and normal tissue is not always spared. While early treatment-related organ specific toxicities are not always apparent, many childhood cancer survivors report symptoms that interfere with daily life, including exercise induced shortness of breath, fatigue, and reduced capacity to participate in physical activity. These symptoms may be a hallmark of premature aging, or frailty. Frailty is a phenotype most commonly described in older adults; it indicates persons who are highly vulnerable to adverse health outcomes. Frailty may help explain why nearly two thirds of childhood cancer survivors have at least one severe chronic health condition 30 years from diagnosis, why childhood cancer survivors are more likely than peers to be hospitalized for non-obstetrical reasons, and why they have mortality rates more than eight times higher than age-and-gender matched members of the general population. The aims of this proposal are to enumerate the prevalence of physiologic frailty over time in a group of young adult survivors of childhood cancer, to describe the association between frailty and the development or progression of chronic conditions, and to describe the associations between personal factors, cancer-related treatment modalities, health behaviors, and frailty in this population.

抽象的过去 40 年来，儿童癌症治疗取得了长足进步，如今，超过 80% 的癌症儿童被诊断患有恶性肿瘤的儿童将成为长期幸存者。目前，有超过35万居住在美国的儿童癌症幸存者；其中近 250,000 人年龄小于年龄 40 岁。不幸的是，儿童癌症的治疗仍然需要旨在破坏的药物恶性细胞系和正常组织并不总是能幸免。虽然早期治疗相关的器官特异性毒性并不总是很明显，许多儿童癌症幸存者报告说症状干扰了日常生活生活，包括运动引起的呼吸短促、疲劳以及参与体育活动的能力下降活动。这些症状可能是过早衰老或虚弱的标志。虚弱是最常见的一种表型常见于老年人；它表示极易受到不良健康影响的人结果。虚弱可能有助于解释为什么近三分之二的儿童癌症幸存者至少患有一种诊断后 30 年出现严重的慢性健康问题，为什么儿童癌症幸存者比同龄人因非产科原因住院，以及为什么他们的死亡率是其八倍以上高于年龄和性别匹配的一般人群。该提案的目的是列举一组年轻的童年幸存者随着时间的推移生理虚弱的患病率癌症，描述虚弱与慢性病的发生或进展之间的关联，并描述个人因素、癌症相关治疗方式、健康状况之间的关联该人群的行为和脆弱性。
