项目摘要
Cancer is a common cause of [functional decline and morbidity] in older adults, with more than two-thirds of
new cases occurring in adults aged 60 years or more. Surgery is the most effective cancer treatment, but it
brings many risks that threaten recovery of physical function in older patients. Older adults needing surgical
treatment face the threats of age-related loss of muscle [quality, strength and endurance, malnutrition
(including cancer-related nutrition impact)], inflammation, and cachexia [caused by cancer and its
treatments]. Further, older adults often experience marked deterioration of functional abilities and reduced
physical reserve and may never regain their baseline level of physical function. This proposal addresses a gap in
knowledge on perioperative interventions to maximize restoration of functional capacity, minimize muscle loss
due to catabolic circumstances, and prevent malnutrition for these patients. Because a treatment using several
nutrients aimed at multiple mechanisms (targets) is expected to be strongly superior to single nutrient
treatment, we will use this approach to target a number of factors involved in cancer cachexia, including
anorexia, alterations in fat and protein metabolism, and systemic inflammation, as well as to prevent or correct
nutritional deficiencies. We expect this intervention to provide superior recovery of physical function and to
improve [physiologic, metabolic] and Veteran-centered outcomes versus a [typical] treatment. Thus, in a
pragmatic clinical trial, we will test a multi-targeted nutrition intervention, applied in a biphasic pattern (pre-
and post-operatively) in older Veterans newly referred for surgical cancer treatment.
In a two-armed 1:1 randomized controlled trial, we will test this nutrition-optimized treatment for senior health
(NOSH), a multi-targeted treatment provided in biphasic intervals (8 weeks before and 24 weeks after
discharge from surgery), and compare it to a [typical nutrition regimen (Typical )] with regards to (Primary
Aim 1) physical function, [(Secondary Aim 2) physiologic and metabolic outcomes], and (Exploratory Aim 3)
Veteran-centered outcomes, including quality of life (QoL), cancer-related nutrition impact symptoms, and
postoperative outcome measures. Older Veterans approaching surgery for [Stage II-III] gastrointestinal or
genitourinary cancer who are at high risk for having their physical abilities markedly decline during treatment
will be enrolled and randomized to NOSH or the [Typical regimen], with both groups prescribed low-intensity
resistance exercise thrice weekly. The NOSH intervention will include generous high-quality protein (30
g/meal; 1.5 g/kg/d) and other key nutrients linked with muscle preservation, namely b-hydroxy-b-
methylbutyrate, a metabolite of the amino acid leucine (HMB; 3 g/d), and vitamin D and a daily multivitamin
supplemented to a vitamin D level of 800 IU/d). Aim 1 will evaluate changes in physical function in the NOSH
intervention arm relative to the [Typical regimen]. Our working hypothesis is that the NOSH intervention will
result in improved physical function (Aim 1) and [physiologic and metabolic outcomes (Aim 2) relative to the
Typical regimen.] We also predict improvements in Veteran-centered outcomes (Aim 3).
This research addresses an important gap in the evidence for best practice of nutritional care for frail older
adults approaching surgical cancer treatment. If the hypotheses of this study are correct, there will be strong
evidence for a major change in treatment approaches for a heretofore mostly neglected population of high-risk
older adults with cancer. More importantly, this improvement in cancer treatment will lead to stronger, more
rapid physical recoveries and better quality of life for this population. The findings will also benefit the VA by
decreasing demands on the health care system via reductions in postoperative complications and the hastening
of recovery of physical function.
癌症是老年人[功能衰退和发病]的常见原因,超过三分之二的老年人
新病例发生在60岁或以上的成年人中。手术是最有效的癌症治疗方法,但它
带来了许多威胁老年患者身体功能恢复的风险。需要手术的老年人
治疗面临着与年龄有关的肌肉[质量,力量和耐力,营养不良]损失的威胁
(包括癌症相关的营养影响)]、炎症和恶病质[由癌症及其
治疗]。此外,老年人经常经历功能性能力的明显退化和功能性能力的降低。
身体储备,可能永远无法恢复其身体功能的基线水平。该提案解决了以下方面的差距:
了解围手术期干预措施,以最大限度地恢复功能能力,最大限度地减少肌肉损失
由于分解代谢的情况下,并防止这些患者营养不良。因为使用几种药物的治疗
针对多个机制(目标)的营养素预计将强烈优于单一营养素的上级
治疗,我们将使用这种方法来靶向参与癌症恶病质的一些因素,包括
厌食症,脂肪和蛋白质代谢的改变,以及全身炎症,以及预防或纠正
营养不良我们希望这种干预能提供上级的身体功能恢复,
与[典型]治疗相比,改善[生理、代谢]和以退伍军人为中心结局。因此在
实用的临床试验,我们将测试一个多目标的营养干预,在一个双相模式应用(前,
和手术后)在新近转诊接受外科癌症治疗的老年退伍军人中。
在一项双臂1:1随机对照试验中,我们将测试这种营养优化治疗对老年人健康的影响。
(NOSH),一种多靶向治疗,以双相间隔(治疗前8周和治疗后24周)提供
从手术中出院),并将其与[典型营养方案(典型)](主要
目标1)身体功能,[(次要目标2)生理和代谢结局]和(探索性目标3)
以退伍军人为中心的结局,包括生活质量(QoL)、癌症相关营养影响症状,以及
术后结果测量。老年退伍军人接近手术[阶段II-III]胃肠道或
泌尿生殖系统癌症患者在治疗期间体能显著下降的高风险
将入组并随机分配至NOSH或[典型方案],两组均给予低强度
每周做三次抗阻运动。NOSH干预措施将包括大量优质蛋白质(30
g/餐; 1.5 g/kg/d)和其他与肌肉保存相关的关键营养素,即b-羟基-B-
甲基丁酸,氨基酸亮氨酸的代谢产物(HMB; 3 g/d),维生素D和每日多种维生素
补充至800 IU/d的维生素D水平)。目的1将评估NOSH中身体功能的变化
相对于[典型方案]的干预组。我们的工作假设是,NOSH干预将
导致改善的身体功能(目标1)和[生理和代谢结果(目标2)相对于
典型的养生法]。我们还预测以退伍军人为中心的结果会有所改善(目标3)。
这项研究解决了一个重要的差距,在证据的最佳做法,营养保健体弱老年人
接受癌症手术治疗的成年人。如果这项研究的假设是正确的,
有证据表明,迄今为止大多数被忽视的高风险人群的治疗方法发生了重大变化,
老年癌症患者。更重要的是,癌症治疗的这种改进将带来更强大、更多的
快速的身体恢复和更好的生活质量。这些发现也将有利于VA,
通过减少术后并发症和加快手术时间,
身体机能的恢复。
