DESCRIPTION (provided by applicant): Cancer related fatigue (CRF), defined by the National Comprehensive Cancer Network as "a distressing, persistent, subjective sense of physical, emotional, and cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity," can severely interfere with activities of daily living, physical capacity, and ability to work. There are even reports of fatigue being a factor in patient requests for hastened death. CRF can represent a serious clinical problem after all treatment has ended. In our research with cancer survivors 1 to 3 years after completion of hematopoietic stem cell transplant (HSCT), 40% of those we interviewed reported that CRF was a major obstacle to the resumption of usual activities. Despite its impact on quality of life, CRF is under-reported, under-diagnosed, and under- treated. There is no widely accepted CRF intervention that has demonstrated clinical efficacy. A variety of pharmacologic agents have been studied to treat CRF; most notably psychostimulants, antidepressants, and corticosteroids. But there is not sufficient evidence to recommend the use of any of the currently available pharmacologic agents. A number of non-pharmacologic strategies have been tested. The most promising are exercise and cognitive-behavior therapy (CBT). Results from two randomized clinical trials suggest that exercise and CBT are equal in overall efficacy, but with only moderate effects. Indeed, at this time there is no "gold standard" treatment for CRF. One promising new intervention for CRF is "bright white light" (BWL --- systematic daily 30-minute exposure to bright white light from a commercially available "lightbox") treatment. In a small randomized controlled clinical trial, BWL was protective against increases in sleep disturbances, mood symptoms and fatigue across cycles of chemotherapy. We want to investigate BWL to control CRF in 1 to 3 year survivors of HSCT for three reasons. First, CRF is a major problem for a large proportion of survivors (40%). Second, BWL may be more acceptable to survivors than CBT or exercise because BWL is less physically demanding and can be carried out at home. Third, BWL is likely to be less expensive since it can be implemented by phone, requiring less professional and patient time and effort than that required for exercise and CBT. The feasibility of the proposed research is assured by the fact that we have identified a group of 150 HSCT survivors who report clinically significant levels of CRF and who have provided informed consent to participate in further research. Specific Aims: 1) Develop and pilot test a BWL exposure intervention with HSCT survivors suffering from CRF to assess the impact on fatigue, sleep quality, and quality of life using objective and subjective measures; 2) To investigate the possible mediating effects of depression on fatigue; and 3) Assess the feasibility and acceptability of BWL as an intervention for CRF in cancer survivors. PUBLIC HEALTH RELEVANCE: Cancer related fatigue (CRF) severely interferes with cancer survivors' daily living, physical capacity, and ability to work, and can linger long after all treatment has ended. To date, CRF treatments have produced only moderate results. The proposed project will investigate the impact of systematic bright white light exposure in cancer survivors to minimize their CRF.

描述（由申请人提供）：癌症相关疲劳（CRF），由国家综合癌症网络定义为“与癌症或癌症治疗相关的痛苦，持续，主观的身体，情感和认知疲劳或疲惫，与最近的活动不成比例”，可能严重干扰日常生活活动，身体能力和工作能力。甚至有报道称，疲劳是病人要求加速死亡的一个因素。在所有治疗结束后，CRF可能是一个严重的临床问题。在我们对完成造血干细胞移植（HSCT）后1至3年的癌症幸存者的研究中，我们采访的40%的人报告说，CRF是恢复正常活动的主要障碍。尽管对生活质量有影响，但慢性肾功能衰竭的报告、诊断和治疗都不足。目前还没有被广泛接受的CRF干预措施已被证明具有临床疗效。研究了多种药物治疗慢性肾功能衰竭；最著名的是精神兴奋剂，抗抑郁药和皮质类固醇。但是没有足够的证据推荐使用任何现有的药物。一些非药物策略已经被测试过。最有希望的是运动和认知行为疗法（CBT）。两项随机临床试验的结果表明，运动和CBT在总体疗效上是相等的，但只有适度的效果。事实上，目前还没有治疗慢性肾功能衰竭的“黄金标准”。一种很有前景的CRF新干预措施是“明亮白光”（BWL——每天系统地暴露在来自市售“灯箱”的明亮白光下30分钟）治疗。在一项小型随机对照临床试验中，BWL对化疗周期中睡眠障碍、情绪症状和疲劳的增加有保护作用。出于三个原因，我们希望研究BWL对1至3年HSCT存活患者CRF的控制作用。首先，CRF是很大一部分幸存者（40%）的主要问题。其次，与CBT或运动相比，BWL可能更容易被幸存者接受，因为BWL对身体的要求较低，可以在家中进行。第三，BWL可能更便宜，因为它可以通过电话实施，比锻炼和CBT需要更少的专业和耐心的时间和精力。我们已经确定了一组150名HSCT幸存者，他们报告了临床显著水平的CRF，并提供了参与进一步研究的知情同意，这一事实确保了拟议研究的可行性。具体目的：1)开发和试点试验BWL暴露干预HSCT幸存者患有CRF，评估疲劳，睡眠质量和生活质量的影响，使用客观和主观的措施；2)探讨抑郁对疲劳可能的中介作用；3)评估BWL作为癌症幸存者CRF干预的可行性和可接受性。
