简要总结
Inflammation has been consistently associated with psychoneurological symptoms (PNS) among breast cancer survivors (BCS). Evidence supporting interventional strategies promoting symptom-self management in reducing inflammation-induced PNS in BCS is limited. Current guidelines for BCS encourage the consumption of foods rich in omega-3 fatty acids. The omega-3 fatty acid docosahexaenoic acid (DHA), abundantly available in fish, has a role in inflammatory downregulation. Low dietary DHA has been associated with inflammation and fatigue in BCS. Dietary planning targeting increased fish consumption thereby reducing red and processed meats are components of the major nutritional recommendations for BCS. A critical gap exists in knowledge regarding interventions promoting adherence to dietary guidelines in BCS supporting PNS self-management. This investigation uses personalized meal planning among BCSs (n=150) who are 1-2 years post-treatment for early-stage breast cancer and experiencing PNS (pain, fatigue, depression, sleep disturbance, stress) to evaluate the feasibility of a personalized meal planning approach in supporting adherence to current dietary guidelines for BCS. As a first step in this program of research, we will evaluate the feasibility of an personalized meal planning approach in promoting adherence to dietary guidelines for BCS through evaluating the feasibility of a personalized meal planning approach in a cohort of BCSs with respect to recruitment, group allocation, salivary inflammatory quantification and receptivity to and adherence with dietary interventions. This investigation will also contribute to a preliminarily evaluation of the efficacy of high or low fish diet in reducing inflammation (IL-1β, IL-6, TNF-a) and PNS symptoms. Nationally, there is a priority for the development of personalized health strategies supporting self-management of adverse symptoms. This investigation focused on PNS in BCS is an initial step in generating new knowledge in efficacious approaches toward guiding decisions on dietary behavior change strategies that are personalized, cost-effective, and sustainable.

结局指标
主要结局
Change from baseline depressive symptom at week 10
时间窗: baseline, Week 3 and Week 10
Epidemiological Studies Depression Scale is 20-item self-report instrument. Each item is scored 0-4 at a 4-point scale, yielding a total between 0 and 80. A higher score indicates a worse depressive symptom.
Change from baseline pain at week 10
时间窗: baseline, Week 3 and Week 10
Brief Pain Inventory short form assesses the severity of pain, location of pain, pain medications, amount of pain relief in the past 24 hours or the past week, and the impact of pain on daily functions. Each item is scored 0-10 at a 10-point scale, with 0 representing no pain or no pain interference and 10 representing worst pain or complete pain interference. The mean of 4 severity items will be used as a measure of pain severity, and the mean of the 7 interference items will be used as a measure of pain interference.
Change from baseline fatigue at week 10
时间窗: baseline, Week 3 and Week 10
Brief Fatigue Inventory short form is a 9-item scale to assess cancer-related fatigue and its impact on daily functioning. Each item score 0-10 at a 10-point scale. On the BFI, severe fatigue can be defined as a mean score of 7 or higher.
Change from baseline sleep disturbance at week 10
时间窗: baseline, Week 3 and Week 10
The 21-item General Sleep Disturbance Scale consists of items evaluating various aspects of sleep disturbance (quality and quantity of sleep, sleep onset latency, number of awakenings, excessive daytime sleepiness, and medication use) over the past week. Items are rated on a scale ranging from 0 (never) to 7 (every day). All items are summed to produce a total score ranging from 0 (no sleep disturbance) to 147 (extreme sleep disturbance).
Change from baseline perceived stress at week 10
时间窗: baseline, Week 3 and Week 10
Levels of stress will be measured by the 10-item Perceived Stress Scale. Each item is rated on a 5-point scale ranging from 0 (never) to 4 (very often). The final score is obtained by reversing responses to the four positively stated items and then summing across all scale items. A higher score represents a higher perceived stress.
次要结局
- Change from baseline salivary inflammatory markers at week 10(3 years)
