DESCRIPTION (provided by applicant): Several randomized controlled trials have demonstrated that exercise can benefit cancer patients in terms of their physical functioning and symptoms. However, few studies have included patients with advanced disease, a group that is living longer with their disease as more treatments are developed. For example, with the recent development of multiple novel agents in the treatment of metastatic colorectal cancer, the overall survival of these patients has nearly tripled. Exercise may help these patients maintain function and manage symptoms, and facilitate their continuing therapy for as long as it is tolerated and effective in controlling disease. The goal of the proposed study is to assess the feasibility and develop preliminary estimates of effect size of a home- based exercise intervention on physical functioning of patients with metastatic and/or recurrent colon cancer in the setting of both a comprehensive cancer center and the community clinical oncology practice network (CCOP). This R21 is proposed to collect data to help plan for a large trial of the intervention. The specific aims of this R21 address three areas related to planning a larger trial: (1) Effect sizes: We aim to develop estimates of the effect size of the exercise intervention on the primary outcome of physical functioning (self-reported and performance tests) and the secondary outcomes of symptoms (fatigue, sleep, pain, nausea, psychological distress) of patients with advanced colon cancer, compared to an attention control intervention (relaxation training); (2) Feasibility: The proposed research will evaluate study feasibility, operationalized as patient adherence, program implementation, contamination (e.g., intervention given or extent of exercise in control group), patient satisfaction, and implementation complexity as rated by clinic staff. (3) Theory: To explore Social Cognitive Theory-based model of predictors of adherence to exercise. We will evaluate psychometric characteristics of the measures of these variables and estimate the effects of the exercise intervention on the hypothesized mediators, as well as explore associations between the model variables and exercise adherence. This study will recruit patients with unresectable stage IV or recurrent colon cancer (ECOG performance status 0-1) who have started a new chemotherapy regimen in the past 28 days. Participants will be randomized to one of two arms: (1) Home-based exercise including pedometers for monitoring walking and resistance bands for functional strength training; (2) Relaxation training using diaphragmatic breathing and guided visualization. The relaxation training arm is included as an attention control, since many of the outcomes for the proposed study, as well as any potential future trials, will rely on self-report. Both study arms will receive print materials and telephone counseling from M. D. Anderson study staff to encourage adherence to the behavior, as well as a letter and brief advice from the patient's oncologist about the importance of exercise or relaxation training. Participants will complete questionnaires when they enter the study and after 16 weeks of intervention. They also will undergo brief physical performance tests in the clinic at baseline and at 16 weeks. PUBLIC HEALTH RELEVANCE: The goal of this study is to gather preliminary information on the effectiveness and feasibility of an exercise intervention for patients with advanced colon cancer. We will assess whether an exercise intervention in which patients receive telephone counseling, advice from their oncologist, written materials, DVD instructions, and a pedometer and resistance bands improves the physical functioning and symptoms of patients, compared to a relaxation training intervention. If this intervention is effective, it could be provided to patients through their oncologist's office, and may help them maintain activities of daily living and independence for longer periods of time during treatment.

描述（由申请人提供）：几项随机对照试验表明，运动可以使癌症患者在身体功能和症状方面受益。然而，很少有研究包括晚期疾病患者，随着更多治疗方法的开发，这一群体的疾病寿命更长。例如，随着近年来在转移性结直肠癌治疗中开发出多种新型药物，这些患者的总生存率几乎增加了两倍。运动可以帮助这些患者维持功能和控制症状，并促进他们的持续治疗，只要它是耐受的，并有效地控制疾病。拟议研究的目的是评估在综合癌症中心和社区临床肿瘤学实践网络（CCOP）的背景下，基于家庭的运动干预对转移性和/或复发性结肠癌患者身体功能的可行性并初步估计其效应量。R21的目的是收集数据，以帮助计划一项大型干预试验。本R21的具体目标涉及与计划更大规模试验相关的三个方面：（1）效应量：我们的目标是估计运动干预对身体功能主要结果的影响大小（自我报告和性能测试）和症状的次要结局（疲劳，睡眠，疼痛，恶心，心理困扰）与晚期结肠癌患者相比，（放松训练）;（2）可行性：拟议的研究将评估研究的可行性，可操作性为患者依从性、项目实施、污染（例如，给予的干预或对照组中的锻炼程度）、患者满意度和实施复杂性。(3)理论：探讨基于社会认知理论的运动坚持性预测因素模型。我们将评估这些变量的心理测量学特征，并估计运动干预对假设中介的影响，以及探索模型变量和运动依从性之间的关联。本研究将招募在过去28天内开始新化疗方案的不可切除IV期或复发性结肠癌（ECOG体能状态0-1）患者。参与者将被随机分配到两组中的一组：（1）家庭锻炼，包括用于监测行走的计步器和用于功能性力量训练的阻力带;（2）使用呼吸法和引导可视化的放松训练。放松训练臂作为注意力控制被包括在内，因为拟议研究的许多结果以及任何潜在的未来试验都将依赖于自我报告。两个研究组都将收到M. D.安德森研究人员鼓励坚持的行为，以及一封信和简短的意见，从病人的肿瘤学家的重要性，运动或放松训练。参与者将在进入研究时和干预16周后完成问卷调查。他们还将在基线和第16周时在诊所接受简短的体能测试。公共卫生相关性：本研究的目的是收集关于运动干预对晚期结肠癌患者的有效性和可行性的初步信息。我们将评估与放松训练干预相比，患者接受电话咨询、肿瘤科医生的建议、书面材料、DVD说明、计步器和阻力带的运动干预是否改善了患者的身体功能和症状。如果这种干预是有效的，它可以通过他们的肿瘤科医生的办公室提供给患者，并可能帮助他们在治疗期间维持日常生活和独立的活动更长的时间。
