DESCRIPTION (provided by applicant): Nearly 80% of children and adolescents with cancer survive 5 or more years after diagnosis and are effectively cured. A significant number of childhood cancer survivors are at risk for cardiovascular (CV) disease resulting from treatment with anthracycline chemotherapy and radiation to CV structures. Previous studies indicate that the frequency of premature CV disease is substantial in this young adult population, and it significantly increases the risk of early mortality. Because most at-risk childhood cancer survivors are asymptomatic, periodic monitoring for late CV complications is critical. However, few survivors undergo CV screening and social and behavioral factors such as knowledge deficits, lack of access to preventive care, and unhealthy lifestyles may exacerbate risk of CV complications. Prevention of CV disease in this growing, at-risk population requires individualized information based on specific treatment exposures and individualized support based on important behavioral constructs. This proposal aims to test a 2-tiered tailored intervention-Evaluation of Cardiovascular Health Outcomes among Survivors (ECHOS)-designed to inform childhood cancer survivors about their individual cardiac risk and follow-up recommendations and to provide motivational support for CV screening. The ECHOS trial will test if the addition of telephone motivational interviewing, tailored to behavioral constructs, is superior to the current standard of care in increasing survivors' CV screening; 815 adult survivors whose cancer was treated with chest radiation and/or anthracycline chemotherapy and who have not had CV screening in the past five years will be eligible to participate. Of these, 652 will be randomly assigned to receive either: 1) a mailed individualized cancer treatment summary with recommendations for CV follow-up and lifestyle modification (standard care) or 2) standard care plus telephone counseling by an advanced- practice nurse that incorporates motivational interviewing techniques tailored to survivors' baseline measures of knowledge, beliefs, readiness for follow-up, motivation, self-efficacy, affect, fear, and survivor-provider interaction. The primary outcome is CV screening adherence, defined as completion or failure to complete an imaging evaluation of left ventricular systolic function (i.e., echocardiogram, multiple uptake gated acquisition scan, or cardiac magnetic resonance imaging). The study population will be recruited from a well- defined cohort of childhood cancer survivors participating in the Childhood Cancer Survivor Study (CCSS). A broad-based health behavior model adapted to childhood cancer survivors will guide the intervention. Secondary aims will evaluate the intervention's cost-effectiveness as well as intervention-related changes in survivors' knowledge, motivation, fear, beliefs, affect, readiness for medical follow-up, and self-efficacy. Knowledge derived from this research will provide the background for future evaluations of the impact of health screening on improving quality of care and reducing cancer-related morbidity in childhood cancer survivors. PUBLIC HEALTH RELEVANCE: Because most pediatric malignancies can now be cured, there is an increasing number of survivors at risk of late cardiovascular (CV) complications of anthracycline chemotherapy and/or irradiation of CV structures. In this group, the risk of cardiac death is 6 to 10 times that of the age- and gender-matched population, yet few adults surviving childhood cancer undergo CV screening. CV complications may be exacerbated by social and behavioral factors, such as knowledge deficits, lack of access to preventive care, and unhealthy lifestyle. We therefore propose to test a 2-armed tailored intervention-Evaluation of Cardiovascular Health Outcomes among Survivors (ECHOS)-designed to provide adult childhood cancer survivors with their individual cardiac risk and follow-up recommendations and to provide motivational support to promote CV screening. We expect the intervention to increase childhood cancer survivors' CV screening adherence, and therefore potentially significantly modify the morbidity and mortality of CV disease in this at-risk population.

描述（申请人提供）：近80%的儿童和青少年癌症患者在确诊后存活5年或更长时间，并得到有效治愈。大量儿童癌症幸存者由于蒽环类化疗和对心血管结构的放射治疗而面临心血管（CV）疾病的风险。先前的研究表明，在这一年轻成年人群中，过早心血管疾病的频率很高，并且显著增加了早期死亡的风险。由于大多数高危儿童癌症幸存者无症状，因此定期监测晚期CV并发症至关重要。然而，很少有幸存者接受CV筛查，社会和行为因素，如知识不足、缺乏预防保健和不健康的生活方式，可能会加剧CV并发症的风险。在这一不断增长的高危人群中，预防心血管疾病需要基于特定治疗暴露的个性化信息和基于重要行为构建的个性化支持。本提案旨在测试一种两层定制干预——幸存者心血管健康结局评估（ECHOS）——旨在告知儿童癌症幸存者他们的个人心脏风险和随访建议，并为CV筛查提供动机支持。ECHOS试验将测试是否增加电话动机访谈，根据行为结构量身定制，在增加幸存者CV筛查方面优于当前的护理标准；815名接受过胸部放疗和/或蒽环类化疗且在过去五年内未接受过CV筛查的成年癌症幸存者将有资格参加研究。其中，652人将被随机分配接受：1)邮寄的个体化癌症治疗总结，包括CV随访和生活方式改变的建议（标准护理）；2)标准护理加高级执业护士的电话咨询，包括针对幸存者的知识、信念、随访准备、动机、自我效能、影响、恐惧和幸存者-提供者互动等基线措施量身定制的动机访谈技术。主要结局是心血管筛查的依从性，定义为完成或未能完成左心室收缩功能的影像学评估（即超声心动图、多重摄取门控采集扫描或心脏磁共振成像）。研究人群将从参与儿童癌症幸存者研究（CCSS）的明确定义的儿童癌症幸存者队列中招募。一个适用于儿童癌症幸存者的基础广泛的健康行为模型将指导干预。次要目标将评估干预的成本效益，以及在幸存者的知识、动机、恐惧、信念、影响、对医疗随访的准备和自我效能方面与干预相关的变化。从这项研究中获得的知识将为未来评估健康筛查对提高护理质量和减少儿童癌症幸存者癌症相关发病率的影响提供背景。
