Efficacy of Massage for the Treatment of Cancer-Related Fatigue (CRF) in Prostate Cancer Survivors

Overview

Cancer-related fatigue (CRF) is a prevalent and debilitating symptom experienced by cancer survivors. CRF can persist for months or years after cancer therapy is completed and has a negative impact on all areas of mental and physical function. Treatment options for CRF are extremely limited and finding safe, inexpensive, and effective interventions for managing this distressing symptom are urgently needed. Massage therapy is one of the fastest growing complementary therapies. A recently completed study in breast cancer survivors with CRF found that Swedish Massage Therapy (SMT) caused a significant reduction in fatigue and improvement in quality of life. This study investigates the effects of massage therapy on CRF among prostate cancer survivors. The study will evaluate whether SMT improves quality of life, depression, and anxiety. Second, this study will evaluate if SMT reduces CRF by decreasing the pro-inflammatory cytokine Interleukin-6 (IL-6). Lastly, to establish measures of reduced fatigue beyond self report at the treatment visits, the researchers will implement continuous, real-time monitoring of physiologic and psychological signs and symptoms, throughout the treatment period. This study will improve care for CRF and other hard-to-manage symptoms of cancer treatment and provide preliminary evidence of immune modulation as a potential mechanism of action. This study is a randomized clinical trial to test the efficacy of Swedish massage therapy (SMT) versus an active control condition (light touch, LT) on cancer related fatigue in men with prostatic cancer, at least 2 months after the end of their radiation therapy. The primary outcome is the Multidimensional Fatigue Inventory (MFI). Secondary outcomes are the Patient-Reported Outcomes Measurement System (PROMIS) Fatigue Scale, plasma concentrations of cytokine IL-6, self-reported quality of life, depression, and anxiety, wearable measures of activity and sleep, and Automated Monitoring of Symptom Severity (AMoSS) ratings.

Fatigue is the most common, and one of the most devastating symptoms among patients with cancer. According to the National Comprehensive Cancer Network (NCCN), cancer-related fatigue (CRF) is "a distressing, persistent, subjective sense of physical, emotional, and/or cognitive exhaustion related to cancer or its treatment that is not proportional to recent activity". Fatigue occurs across the spectrum of cancer types and treatments. CRF has a negative impact on all areas of function, including mood, physical function, work performance, social interaction, family care, cognitive performance, schoolwork, and community activities. CRF has been rated as more troublesome and to have a greater negative impact on quality of life than other cancer-related symptoms such as pain, depression, and nausea. CRF can persist for months or years after cancer therapy is completed. Meaningful, evidence-based treatment options for CRF are limited. Over 50% of patients with cancer have used a complementary and alternative medicine (CAM) approach for symptom management and quality of life. One of the widely employed CAM interventions is massage therapy. Most of the studies investigating massage for patients with cancer focus on depression, anxiety, or pain as the outcomes of interest. A previous investigation of breast cancer survivors reported decreases in mood symptoms and an improvement in fatigue, however, CRF was not the primary outcome measure. This randomized clinical trial will test the efficacy of Swedish massage therapy (SMT) vs. an active control condition (light touch, LT) on cancer related fatigue in men with prostatic cancer, at least 2 months after the end of their radiation therapy. Participants will receive weekly treatments for 6 weeks. The aims of the study are as follows: Aim 1: To conduct a feasibility study to determine whether a 6-week SMT intervention can decrease CRF among prostate cancer survivors who have received radiation therapy and have CRF. Aim 2: To determine whether the hypothesized decrease in CRF is due to SMT modulating the immune system of subjects with CRF. The researchers hypothesize that SMT will decrease plasma concentrations of IL-6 (a pro-inflammatory cytokine) more than LT and that the decrease in plasma IL-6 will mediate the decrease in fatigue as assessed with the MFI. Aim 3: To determine whether SMT improves self-reported quality of life, depression, and anxiety more than LT, as assessed (respectively) by the Quality of Life, Enjoyment, and Satisfaction Questionnaire - short form (Q-LES-Q), the Quick Inventory of Depressive Symptoms - Self-Report (QIDS-SR), and the Generalized Anxiety Disorder 7-item (GAD-7) scale. Aim 4: To evaluate the peripheral physiological changes associated with treatment of CRF. The researchers predict that treatment with SMT will cause a progressive increase in wearable measures of activity and step count, improved sleep quality (duration and latency), and decrease in pulse over 6 weeks when compared to baseline measures. Aim 5: To determine if valid and useful tests of SMT effectiveness for treating CRF can be obtained through daily self-report ratings of fatigue and continuous monitoring of physiological signs. The researchers predict that SMT will cause a significant decrease in daily self-ratings of fatigue and mood when compared to baseline ratings and that the decreases in daily self-ratings of fatigue and mood observed with SMT will correlate with changes in Q-LES-Q, QIDS-SR, GAD-7 scores obtained at in-person visits as well as physiological signs.
