Acupoint stimulation for cancer-related fatigue: A quantitative synthesis of randomised controlled trials

Somatic acupressure for the management of the fatigue-sleep disturbance-depression symptom cluster in breast cancer survivors: a study protocol for a phase III randomised controlled trial

INTRODUCTION

The fatigue-sleep disturbance-depression symptom cluster (FSDSC) is commonly experienced by breast cancer (BC) survivors, leading to a deteriorated quality of life (QoL). Somatic acupressure (SA) has been recommended as a promising non-pharmacological intervention for cancer-related fatigue (the core symptom of the FSDSC) in the guidelines, showing its encouraging role in relieving cancer-related sleep disorders, fatigue and depression. This phase III randomised controlled trial (RCT) is designed to evaluate the effects, safety and cost-effectiveness of SA for managing the FSDSC in BC survivors.

METHODS

This phase III RCT will be a partial-blinded, sham-controlled, three-arm, parallel clinical trial, involving a 7-week SA intervention period and a 12-week follow-up period. 108 BC survivors will be randomly allocated in a ratio of 1:1:1 to either a true SA group (self-administered acupressure plus usual care), a sham SA group (self-administered light acupressure at non-acupoints plus usual care) or a usual care group. The primary outcomes will be the effectiveness of SA on the FSDSC at both the individual symptom level and cluster symptom level. Each individual symptom will be specifically measured by the Brief Fatigue Inventory (fatigue), the Pittsburgh Sleep Quality Index (sleep disturbance) and the Hospital Anxiety and Depression Scale-Depression (depression). The cluster symptom level will be measured by using an FSDSC composite score, an averaging score of three separated 0-10 numeric rating scales for fatigue, depression and sleep disturbance. The secondary outcomes will include QoL (measured by the Functional Assessment of Cancer Therapy-Breast), adverse events and cost-effectiveness. Outcomes will be assessed at baseline (week 0), immediately after intervention (week 7) and follow-up (week 19). All outcomes will be analysed based on the intention-to-treat principle using the Statistical Package for Social Science (SPSS 25) software.

ETHICS AND DISSEMINATION

Ethical approvals of this study have been granted by the Human Research Ethics Committee at Charles Darwin University (H22110) and the Clinical Trial Ethics Committee at the Affiliated Hospital of Zunyi Medical University (KLL-2023-594), and the Second Affiliated Hospital of Zunyi Medical University (KYLL-2023-058). Findings from this trial will be published in peer-reviewed journals and presented at professional conferences.

Far-infrared stimulation of Neiguan acupoints improves heart rate variability and ameliorate fatigue in hemodialysis patients: A randomized trial

BACKGROUND

In 2018, 84 615 patients in Taiwan received hemodialysis, of which about 62% to 97% suffered from fatigue. Fatigue caused by hemodialysis may be mental or physical. However, the detailed mechanism remains unclear. This study aimed to evaluate whether far-infrared stimulation of the Neiguan acupoint (P6) could effectively reduce fatigue and improve heart rate variability (HRV) in hemodialysis patients.

METHODS

We conducted a two-arm, randomized trial in a hemodialysis center between March 2015 and March 2016. A total of 73 hemodialysis patients were included and were randomly assigned to an experimental group (n = 37) and a control group (n = 36). The experimental group received far-infrared radiation on Neiguan acupoint during hemodialysis for 12 weeks. The outcomes were fatigue level and HRV.

RESULTS

All patients showed moderate fatigue ( M = 26.00 ± 13.01, range = 0-78) at baseline. Far-infrared stimulation on Neiguan acupoint significantly reduced overall fatigue ( β = 24, p < 0.001) and improved HRV ( β = 74.36, p < 0.001). Compared to the control group, the experiment group had significantly reduced fatigue levels in all aspects such as reduced energy and motivation ( β = -2.97, p < 0.001), reduced physical strength ( β = -1.28, p < 0.01), reduced mental capability ( β = -2.38, p < 0.001), reduction in daily activities ( β = -1.48, p < 0.01), depressed mood and loss of control ( β = -1.21, p < 0.05) as well as increased autonomous nervous system activity ( β = 14.71, p < 0.01) in the third month of stimulation.

CONCLUSION

Far-infrared stimulation of the Neiguan acupoints effectively reduces fatigue and increases autonomic nervous system activity in hemodialysis patients.

Feasibility and Usability of EnergyPoints: A Mobile Health App to Guide Acupressure Use for Cancer Symptom Management

OBJECTIVE

To examine the feasibility and usability of EnergyPoints™, an innovative mobile health app that teaches and guides people with cancer to implement daily acupressure to self-manage their fatigue and sleep disturbances.

METHODS AND INTERVENTION

The study used an integrated agile, human-centered approach. Adults (age 18 years and over) with cancer experiencing at least moderate fatigue, and living in the Greater New York City community, were recruited from social media, patient advocacy groups, and referrals. Twenty participants (in 3 sprints of 3, 5, and 12) were video-recorded thinking aloud while using the app for the first time. They then used the app at home to self-administer acupressure (twice daily for 1 week) while continuously wearing a fitness tracker. Each participant completed an exit interview and modified Computer System Usability Questionnaire post-participation.

RESULTS

Participants were ages 40 to 76 years and 65% female; 65% were non-Hispanic white. Mean pass rates per ritual exceeded 80%. Users completed (totally or partially) greater than 90% of stimulating acupressure and 70% of relaxing acupressure rituals. Sprint 3 SPs totally completed at least 1 ritual 87% of the time. The majority agreed or strongly agreed the app was easy to use (90%), easy to learn (85%), easy to understand (75%), and effective in helping perform self-acupressure (85%). In an analysis of ease of completing 5 key tasks, all successfully completed the tasks; 3 users required some assistance. Of 654 usability statements, those coded as personal experience/context (197), content related to acupressure learning (105), and content related to the onboarding/profile (71) were most frequent. The design team integrated recommendations into the app before the next sprint.

CONCLUSIONS

Findings supported feasibility and usability, as well as acceptability, and led to significant alterations and improvements. EnergyPoints™ offers an opportunity to mainstream acupressure and help cancer survivors self-manage their symptoms.

The Effects of Complementary Therapies on Patient-Reported Outcomes: An Overview of Recent Systematic Reviews in Oncology

Many patients with cancer make use of complementary medicine alongside conventional medicine, but clinicians in oncology often lack the knowledge to adequately advise patients on the evidence base for complementary therapies. This study aims to provide an overview of recently published systematic reviews that assess the effects of complementary therapies on patient-reported health outcomes in patients with cancer. Systematic reviews, including a meta-analysis of at least two randomized controlled trials, were identified from the PubMed, Embase, Cochrane Library, CINAHL and PsycINFO databases. The methodological quality was assessed with AMSTAR 2. One hundred systematic reviews were included. The results suggest that several complementary therapies can improve health outcomes reported by patients with cancer, such as acupuncture to relieve pain, music interventions to reduce anxiety and yoga to improve cancer-related fatigue. The side effects related to complementary therapy use are generally mild. The results remain inconclusive for some intervention-outcome combinations. Many of the included systematic reviews insufficiently assessed the causes and impact of bias in their interpretation of the results. This overview of systematic reviews can support clinicians in counselling their patients on this topic and provide directions for future research and clinical practice guidelines in the field of complementary medicine.

The Role of Complementary and Alternative Medicine on Cancer-Related Fatigue in Adults: An Overview of Systematic Reviews

BACKGROUND

Cancer-related fatigue (CRF) has an enormous adverse impact on quality of life and subsequent therapy of cancer patients. Complementary and alternative medicine (CAM) is reported to improve CRF in many systematic reviews (SRs), but the effects are controversial because of variations in the quality and outcomes.

METHODS

Thirteen databases were searched from inception to September 2022. Only SRs of randomized controlled trials (RCTs) were included. We assessed the quality of included SRs with the AMSTAR-2 tool, the strength of evidence with the GRADE system, the risk of bias with the ROBIS tool, and the integrity of SRs with the PRISMA checklist.

RESULTS

We included 30 eligible SRs (27 meta-analyses). Based on the AMSTAR-2 tool, 29 SRs were rated as "critically low" quality, and only one was rated as "low" quality. With the ROBIS tool, 19 SRs demonstrated a low risk of bias. According to the PRISMA checklist, no SRs reported all the items, and 10 SRs sufficiently reported over 70%. Based on the GRADE system, 7 outcomes were assessed as high-quality evidence.

CONCLUSION

This overview demonstrates promising evidence for the effectiveness of CAM interventions in the treatment of CRF in adults. The roles of qigong, music, auricular point therapy, and dietary supplements in CRF need further evaluation. Although findings are mixed, it is recommend to select appropriate CAM to manage cancer-related fatigue under the guidance of physicians. More studies with rigorous methodological designs and sufficient sample sizes are needed.

An Evidence-Based Somatic Acupressure Intervention Protocol for Managing the Breast Cancer Fatigue-Sleep Disturbance-Depression Symptom Cluster: Development and Validation following the Medical Research Council Framework

BACKGROUND

Somatic acupoint stimulation (SAS) has been frequently utilised as a promising intervention for individual cancer-related symptom management, such as fatigue, sleep disturbance and depression. However, research evidence regarding the role of SAS in mitigating the fatigue-sleep disturbance-depression symptom cluster (FSDSC) has been scant. This study was conducted to develop an evidence-based SAS intervention protocol that can be further implemented in a Phase II randomized controlled trial (RCT) to manage the FSDSC in breast cancer survivors.

METHODS

The Medical Research Council Framework for Developing and Evaluating Complex Intervention (MRC framework) was employed to guide the development procedures of the SAS intervention protocol, including the identification of an existing evidence base, the identification of theories and practice standards, and the validation of the SAS intervention protocol. A content validity study was performed through an expert panel to assess the scientific and practical appropriateness of the SAS intervention protocol. The content validity index (CVI), including item-level CVI and protocol-level CVI, were calculated to evaluate the consensus level of the expert panel.

RESULTS

Key components of the SAS protocol, including the acupoint formula, the SAS modality, technique, intensity and frequency were identified for both a true and placebo SAS intervention based on the best available research evidence retrieved from systematic reviews, clinical trials, and relevant theories, particularly regarding the inflammatory process, yin-yang theory, zang-fu organs and meridians theory, and acupressure practical standards. The true SAS intervention was determined as daily self-administered acupressure on specific acupoints for seven weeks. The placebo SAS was designed as light acupressure on non-acupoints with the same frequency and duration as the true SAS. Excellent content validity was achieved after one round of expert panel assessment, with all the key components of the true and placebo SAS protocols rated as content valid (CVI ranged from 0.86 to 1.00).

CONCLUSIONS

A research-informed, theory-driven and practically feasible SAS intervention protocol for the FSDSC management in breast cancer survivors was developed following the MRC framework. The feasibility and acceptability of the SAS intervention will be further tested in breast cancer survivors through a Phase II RCT.

Acupuncture and Moxibustion for Cancer-Related Fatigue: An Overview of Systematic Reviews and Meta-Analysis

Simple Summary

Acupuncture, per se, is not used for treating cancer. However, acupuncture is used for treating several cancer-related symptoms, such as, for example, pain, antiestrogen-induced hot flashes, as well as cancer-related fatigue (CRF). There are several studies that assess the evidence of acupuncture for palliative cancer treatment; but there are none for CRF. The aim of this overview, therefore, was to comprehensively summarize and critically evaluate the current evidence of the efficacy of AT in the management of CRF.

Abstract

Although acupuncture (AT) is used in the treatment of CRF, the evidence from different systematic reviews (SRs) of AT has not yet been comprehensively evaluated. Moxibustion, which is a treatment method that is well established within Traditional East Asian Medicine, applies the heat of burning herbs towards or onto special points on the skin. Commonly, the herb Artemisia vulgaris, is used. It has been used for palliative cancer care, as well as for CRF. The aim of this overview was to evaluate the efficacy of AT and moxibustion in the management of CRF. Eleven databases were searched through for studies that were published from their dates of inception to February 2022. The study selection, the data extraction, and the assessment were performed independently by two researchers. The methodological and report quality were assessed by using the Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) tool. The evidence quality was evaluated by using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Fifteen SRs on AT (n = 10) and moxibustion (n = 5) treatments for CRF were included, and they include 169 randomized controlled trials and 14,392 participants. All of the SRs that were evaluated by the AMASTAR-2 had more than one deficiency, and so all of the SRs were rated as either low or critically low. For the GRADE, 18 outcomes were rated as very-low-quality evidence, 13 as low-quality evidence, 3 as moderate-quality evidence, and 0 as high-quality evidence. Most of the SRs reached the potential benefits of AT for CRF. No serious adverse effects were identified. In conclusion, the evidence suggests that, despite the advantages of AT in terms of the improvement in and the safety of the treatment of CRF, the methodological quality of most of these studies is low, which limits our ability to draw definitive meanings. Further research of high quality is needed in order to confirm these findings.

Implementing an evidence-based somatic acupressure intervention in breast cancer survivors with the symptom cluster of fatigue, sleep disturbance and depression: study protocol of a phase II randomised controlled trial

INTRODUCTION

The fatigue-sleep disturbance-depression (FSD) symptom cluster, as one of the most common symptom clusters in breast cancer (BC) survivors, can significantly decrease patients' quality of life. Since the management of the FSD symptom cluster has been unsatisfactory with the use of pharmacological treatments alone, non-pharmacological approaches have, therefore, been recommended. Somatic acupressure (SA) is a promising approach given its potential benefits of cancer-related symptom alleviation and the convenience of self-practice. However, research evidence on using acupressure to manage the FSD symptom cluster has been limited. The proposed trial aims to examine the feasibility and preliminary effects of an evidence-based SA intervention for FSD symptom cluster management in BC survivors.

METHODS AND ANALYSIS

This study will be a phase II randomised controlled trial with three study arms and 1:1:1 allocation. Fifty-one early-stage BC survivors who are experiencing the FSD symptom cluster will be randomly assigned to a true SA group, a sham SA group or a usual care group. All participants will receive an education booklet regarding FSD symptom cluster management advice as the usual care package. The participants in the true SA group will additionally receive a 7-week self-administered SA intervention. The participants in the sham SA group will additionally receive self-administered light acupressure at non-acupoints with the same frequency, session and duration as the true SA group. The primary outcomes will be feasibility outcomes related to subject recruitment and completion of study questionnaires and interventions. The secondary outcomes will be the effects of SA on fatigue, sleep disturbance, depression and quality of life. Descriptive statistics will be used to present all the outcomes. The secondary outcomes will be analysed using an intent-to-treat approach.
