Phase III Trial of Exercise Training in Postsurgical Lung Cancer

描述（由申请人提供）：肺癌是美国男性和女性癌症相关死亡的最常见原因。患有早期肺癌的个体具有由多种机制引起的显著降低的运动能力（例如，疾病病理生理学、治疗、去适应等）。这一点至关重要，因为运动能力差与较高的疾病相关症状、健康相关生活质量（HRQOL）差、对常见年龄相关疾病的易感性增加以及可能的过早死亡相关。尽管它的重要性，有效的干预措施，以提高肺癌患者的运动能力是不可用的。来自我们小组的两项非对照试点研究的结果提供了“原则证明”，即有氧训练是一种安全可行的干预措施，与早期肺癌患者运动能力和HRQOL的适度改善相关。以下两个问题是密切相关的：（1）什么是最有效的运动训练类型，以提高运动能力;（2）这种改善的机制是什么？我们提出了一个前瞻性的，四臂，随机试验，比较三种不同的运动计划相对于久坐不动的对照组150例早期肺癌患者谁完成了癌症治疗的效果。该补助金将有以下主要和次要目标：主要目标：确定有氧训练和阻力训练的效果，相对于注意力控制，对运动能力。次要目的：（1）确定对患者报告结果的影响，（2）检查运动训练-VO 2峰值关系的生理介质，（3）检查干预-患者报告结果关系的心理介质。这项研究将解决几个基本的，但目前尚未回答的问题，关于运动训练在肺癌管理中的作用。从这项临床试验中获得的信息将为未来计划的研究设计提供信息，进一步研究运动训练在肺癌生存连续体中的作用。最后，机械研究结果将提供如何完善运动训练干预措施的见解，以最大限度地提高运动能力和相关结果，在这个服务不足的人群。公共卫生相关性：肺癌是美国男性和女性癌症相关死亡的最常见原因。患有早期肺癌的个体具有由多种机制引起的显著降低的运动能力（例如，疾病病理生理学、治疗、去适应等）。这一点至关重要，因为运动能力差与较高的疾病相关症状、健康相关生活质量（HRQOL）差、对常见年龄相关疾病的易感性增加以及可能的过早死亡相关。尽管它的重要性，有效的干预措施，以提高肺癌患者的运动能力是不可用的。

DESCRIPTION (provided by applicant): Lung cancer is the most common cause of cancer-related death among both men and women in the United States. Individuals with early-stage lung cancer have markedly reduced exercise capacity caused by multiple mechanisms (e.g., disease pathophysiology, treatment, deconditioning, etc.). This is of critical importance since poor exercise capacity is associated with higher disease-related symptoms, poor health-related quality of life (HRQOL), increased susceptibility to common age-related diseases and likely, premature death. Despite its importance, effective interventions to improve exercise capacity among lung cancer patients are not available. Results from two uncontrolled pilot studies from our group have provided 'proof of principle' that aerobic training is a safe and feasible intervention associated with modest improvements in exercise capacity and HRQOL among early-stage lung cancer patients. The following two questions are now germane: (1) what is the most effective type of exercise training to improve exercise capacity; and (2) what are the mechanisms underlying this improvement? We propose a prospective, four-arm, randomized trial to compare the effects of three different exercise programs relative to a sedentary control group among 150 early-stage lung cancer patients who have completed cancer therapy. This grant will have the following primary and secondary aims: Primary aim: determine the effects of aerobic training and resistance training, relative to attention-control, on exercise capacity. Secondary aims: (1) to determine the effects on patient-reported outcomes, (2) to examine the physiological mediators of the exercise training - VO2peak relationship, (3) to examine the psychological mediators of the intervention - patient-reported outcomes relationship. This study will address several fundamental but, currently unanswered questions regarding the role of exercise training in the management of lung cancer. Information gained from this clinical trial will inform the design in future-planned studies further investigating the role of exercise training across the lung cancer survivorship continuum. Finally, the mechanistic findings will provide insight into how to refine exercise training interventions to maximize improvements in exercise capacity and associated outcomes in this underserved population.
