Systematic review of acupuncture in cancer care: a synthesis of the evidence

Acupuncture for Breast Cancer: A Systematic Review and Meta-Analysis of Patient-Reported Outcomes

Abstract

The present systematic review and meta-analysis was undertaken to evaluate the effects of acupuncture in women with breast cancer (BC), focusing on patient-reported outcomes (PROs).

Methods

A comprehensive literature search was carried out for randomized controlled trials (RCTs) reporting PROs in BC patients with treatment-related symptoms after undergoing acupuncture for at least four weeks. Literature screening, data extraction, and risk bias assessment were independently carried out by two researchers.

Results

Out of the 2, 524 identified studies, 29 studies representing 33 articles were included in this meta-analysis. At the end of treatment (EOT), the acupuncture patients’ quality of life (QoL) was measured by the QLQ-C30 QoL subscale, the Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES), the Functional Assessment of Cancer Therapy–General/Breast (FACT-G/B), and the Menopause-Specific Quality of Life Questionnaire (MENQOL), which depicted a significant improvement. The use of acupuncture in BC patients lead to a considerable reduction in the scores of all subscales of the Brief Pain Inventory-Short Form (BPI-SF) and Visual Analog Scale (VAS) measuring pain. Moreover, patients treated with acupuncture were more likely to experience improvements in hot flashes scores, fatigue, sleep disturbance, and anxiety compared to those in the control group, while the improvements in depression were comparable across both groups. Long-term follow-up results were similar to the EOT results.

Conclusions

Current evidence suggests that acupuncture might improve BC treatment-related symptoms measured with PROs including QoL, pain, fatigue, hot flashes, sleep disturbance and anxiety. However, a number of included studies report limited amounts of certain subgroup settings, thus more rigorous, well-designed and larger RCTs are needed to confirm our results.

Late radiation effects in survivors of head and neck cancer: State of the science

Head and neck squamous cell carcinoma is one of the most common neoplasms. Radiotherapy (RT) plays an essential role in the management of such cases. Despite advances in the technique, hyposalivation, xerostomia, dysphagia, trismus, radiation caries, and osteoradionecrosis remain significant late complications of RT. The aim of this narrative review was to summarize and update the main findings related to late side effects of radiotherapy in survivors of head and neck cancer (HNC). Such effects limit the ability to speak, ingest food and medications, and breathe and also exert a negative impact on social well-being and quality of life. This review highlights research in the field for both researchers and clinicians, assisting in the prevention and management of these adverse conditions. The findings can contribute to improving preventive management and multidisciplinary interventions for HNC patients.

Acupuncture for Cancer-Related Anorexia: a Review of the Current Evidence

PURPOSE OF REVIEW

Loss of appetite/anorexia is extremely common among cancer patients, affecting as many as half of newly diagnosed patients and 70% of patients with advanced disease. Effective management of this disabling symptom of cancer remains a major challenge in the field of oncology. We conducted a systematic review of the current evidence on acupuncture and/or moxibustion as an intervention for cancer-related anorexia.

RECENT FINDINGS

Acupuncture, as a part of traditional Chinese medicine practice, has demonstrated effectiveness in managing many cancer- and treatment-related symptoms, especially chemotherapy-induced or postoperative nausea. However, the efficacy of acupuncture in treating cancer-related anorexia/loss of appetite is not clear. The current level of evidence is insufficient to make a definitive conclusion on the benefit of acupuncture/moxibustion for treating chronic cancer-related anorexia/appetite problems. Future large randomized controlled trials of high methodological quality are needed.

Integrative Medicine: Adjunctive Element or Essential Ingredient in Palliative and Supportive Cancer Care?

The aim of supportive cancer care is to actively manage patients' physical, psychologic, and spiritual concerns, independent of prognosis. Complementary and integrative medicine (CIM) is increasingly gaining greater acceptance and support for its beneficial value in supportive cancer care. The utilization of CIM early in the cancer trajectory, during treatment and during survivorship periods, as well as during end of life, addresses a great number of unmet needs that patients affected by cancer raise. In addition, recent research supports the role that CIM has in reducing suffering and distress both physically and emotionally, as well as enhancing well-being in patients affected by cancer and their families. CIM is increasingly seen not only as an adjunctive add-on treatment or perhaps even as a luxury item for the affluent but actually as an important component in supportive cancer care for all patients. It addresses many aspects of care that sometimes are not being addressed with conventional means. With the increase in CIM-related research, as well as the increased clinical experience in oncology programs worldwide, CIM is gradually becoming an essential ingredient in supportive and palliative cancer care. In this narrative review, the authors look systematically at the contribution that CIM has in supportive care in each stage of the cancer trajectory, reflecting the needed role that CIM has in supportive care. The presented data will provide a sampling of the available clinical research for each of the broad stages being described.

Knowledge Mapping of Acupuncture for Cancer Pain: A Scientometric Analysis (2000-2019)

Objective

This study aimed to demonstrate the state of the present situation and trends concerning the global use of acupuncture for cancer pain in the past 20 years.

Methods

Searched the Web of Science database from 2000 to 2019 related to acupuncture for cancer pain, and then used CiteSpace to conduct scientometric analysis to acquire the knowledge mapping.

Results

Yearly output has increased year by year, and the growth rate has become faster after 2012. According to the cluster analysis of institutions, authors, cited references, and keywords, 4, 4, 15, and 14 categories were obtained, respectively. The most productive countries, institutions, and authors are the USA, Mem Sloan Kettering Cancer Center, and Mao JJ, whose frequencies are 196, 24, and 17, respectively. However, the most important of them are Australia, Univ. Maryland, and Bao T, owing to their highest centrality, they are 0.90, 0.21, and 0.09 separately. Moreover, cited references that contributed to the most co-citations are Crew KD (2010), however, the most key cited reference is Roscoe JA (2003). Keywords such as acupuncture, pain, breast cancer, palliative care, and quality of life are the most frequently used. But auricular acupuncture is the crucial keyword. In the cluster analysis of institutions, authors, cited references, and keywords, the more convincing research categories are multiple myeloma, placebo effect, neck malignancies, and early breast cancer, with S values of 0.990, 0.991, 0.990, and 0.923, respectively. Therefore, they can be regarded as research hotspots in this field.

Conclusion

Based on the scientometric analysis in the past 20 years, the knowledge mapping of the country, institution, author, cited reference, and the keyword is gained, which has an important guiding significance for quickly and accurately positioning the trend in this field.

Characteristics and Symptom Burden of Patients Accessing Acupuncture Services at a Cancer Hospital

BACKGROUND

Patients with cancer are often impacted by a significant symptom burden. Cancer hospitals increasingly recognize the value of complementary and integrative therapies to support the management of cancer related symptoms. The aim of this study is to provide a better understanding of the demographic characteristics and symptoms experienced by cancer patients who access acupuncture services in a tertiary hospital in Australia.

METHODS

A retrospective audit was conducted of patients that presented to the acupuncture service at Chris O'Brien Lifehouse between July 2017 and December 2018. Edmonton Symptom Assessment Scale (ESAS) and Measure Yourself Concerns and Wellbeing (MYCaW) outcome measures were used. The quantitative data was analyzed using descriptive statistics and Principal Component Analysis.

RESULTS

A total of 127 inpatients and outpatients (mean age 55, range 19-85) were included with 441 individual surveys completed (264 ESAS, 177 MYCaW). Patients were predominantly female (76.8%) and breast cancer was the most prevalent primary diagnosis (48%). The most prevalent symptoms in the ESAS were sleep problems (88.6%), fatigue (88.3%), lack of wellbeing (88.1%), and memory difficulty (82.6%). Similarly, symptoms with the highest mean scores were numbness, fatigue, sleep problems and hot flushes, whilst neuropathy, and hot flashes were scored as the most severe (score ≥7) by patients. Cluster analysis yielded 3 symptom clusters, 2 included "physical symptoms" (pain, sleep problems, fatigue and numbness/neuropathy), and (nausea, appetite, general well-being), whilst the third included "psychological" symptoms (anxiety, depression, spiritual pain, financial distress). The most frequent concerns expressed by patients (MyCaW) seeking acupuncture were side effects of chemotherapy (24.6%) and pain (20.8%).

CONCLUSION

This audit highlights the most prevalent symptoms, the symptoms with the greatest burden and the types of patients that receive acupuncture services at an Australian tertiary hospital setting. The findings of this audit provide direction for future acupuncture practices and research in hospital settings.

Clinical Evidence for Association of Acupuncture and Acupressure With Improved Cancer Pain: A Systematic Review and Meta-Analysis

Question

Is the use of acupuncture and acupressure associated with improved cancer pain management compared with sham intervention and/or analgesic therapy alone?

Findings

In this systematic review of 17 randomized clinical trials and meta-analysis of 14 trials in the current English-language and Chinese-language literature, a significant association was found between real (compared with sham) acupuncture and reduced pain, and acupuncture combined with analgesic therapy was associated with decreased analgesic use. However, heterogeneity lowered the level of certainty of the evidence.

Meaning

This study found a moderate level of evidence that acupuncture and/or acupressure was significantly associated with lower pain intensity in patients with cancer compared with a sham control, which suggests a potential for a combination of acupuncture and acupressure to help reduce opioid doses in patients with cancer.

Importance

Research into acupuncture and acupressure and their application for cancer pain has been growing, but the findings have been inconsistent.

Objective

To evaluate the existing randomized clinical trials (RCTs) for evidence of the association of acupuncture and acupressure with reduction in cancer pain.

Data Sources

Three English-language databases (PubMed, Embase, and CINAHL) and 4 Chinese-language biomedical databases (Chinese Biomedical Literature Database, VIP Database for Chinese Technical Periodicals, China National Knowledge Infrastructure, and Wanfang) were searched for RCTs published from database inception through March 31, 2019.

Study Selection

Randomized clinical trials that compared acupuncture and acupressure with a sham control, analgesic therapy, or usual care for managing cancer pain were included.

Data Extraction and Synthesis

Data were screened and extracted independently using predesigned forms. The quality of RCTs was appraised with the Cochrane Collaboration risk of bias tool. Random-effects modeling was used to calculate the effect sizes of included RCTs. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation approach.

Main Outcomes and Measures

The primary outcome was pain intensity measured by the Brief Pain Inventory, Numerical Rating Scale, Visual Analog Scale, or Verbal Rating Scale.

Results

A total of 17 RCTs (with 1111 patients) were included in the systematic review, and data from 14 RCTs (with 920 patients) were used in the meta-analysis. Seven sham-controlled RCTs (35%) were notable for their high quality, being judged to have a low risk of bias for all of their domains, and showed that real (compared with sham) acupuncture was associated with reduced pain intensity (mean difference [MD], −1.38 points; 95% CI, −2.13 to −0.64 points; I² = 81%). A favorable association was also seen when acupuncture and acupressure were combined with analgesic therapy in 6 RCTs for reducing pain intensity (MD, −1.44 points; 95% CI, −1.98 to −0.89; I² = 92%) and in 2 RCTs for reducing opioid dose (MD, −30.00 mg morphine equivalent daily dose; 95% CI, −37.5 mg to −22.5 mg). The evidence grade was moderate because of the substantial heterogeneity among studies.

Conclusions and Relevance

This systematic review and meta-analysis found that acupuncture and/or acupressure was significantly associated with reduced cancer pain and decreased use of analgesics, although the evidence level was moderate. This finding suggests that more rigorous trials are needed to identify the association of acupuncture and acupressure with specific types of cancer pain and to integrate such evidence into clinical care to reduce opioid use.

Efficacy of Acupuncture and Moxibustion as a Subsequent Treatment after Second-Line Chemotherapy in Advanced Gastric Cancer

Objective

To explore whether acupuncture and moxibustion can prevent disease progression of advanced gastric cancer patients completing second-line chemotherapy and, if so, the related mechanism.

Method

Progression-free survival (PFS) and overall survival (OS) were main outcome measures. The real-time quantitative PCR was used to detect the expression of genes including T-bet, IFN-γ, GATA3, and IL-4 in peripheral blood mononuclear cells (PBMCs). IL-4, IL-6, Ca199, CRP, and IFN-γ in plasma levels were checked.

Results

170 patients were randomly assigned in a 3 : 2 ratio to receive either acupuncture and moxibustion or sham acupuncture until progression. 135 patients were included in the primary analysis. Both PFS and OS in treatment group were proven to be better than control group. Acupuncture and moxibustion promoted typical Th1 cells drifting, as confirmed by increased T-bet/IFN-γ and decreased GATA3/IL-4 in mRNA levels from PBMCs, as well as upregulating IFN-γ and downregulating IL-4 in plasma levels. IL-6, Ca199, and CRP in plasma levels were also reduced by acupuncture and moxibustion.

Conclusions

Acupuncture and moxibustion can prolong PFS and OS of advanced gastric cancer patients completing second-line chemotherapy by reversing Th1/Th2 shift and attenuating inflammatory responses.

A Quality Brief of an Oncological Multisite Massage and Acupuncture Therapy Program to Improve Cancer-Related Outcomes

Objectives: Cancer treatment can present its own physical and mental challenges resulting in symptoms such as fatigue, stress, pain, nausea, and vomiting. Aurora Health Care is a large health system with 19 cancer centers. Integrative therapies such as acupuncture and massage have demonstrated success in reducing cancer-related symptoms and side effects to conventional cancer treatment and improving patient outcomes. In 2018, 15 of the 19 Aurora Cancer Clinics embedded a replicable Integrative Cancer Care closed model to provide adjuvant therapies for the best patient outcomes. This quality improvement study aimed to explore if the replicable integrative care model could demonstrate consistent outcomes for massage and acupuncture therapies aimed at symptom reduction across multiple oncology clinics. Design: Aurora Cancer Care and Aurora Integrative Medicine designed a reproducible integrative therapy service model to be embedded into the Aurora Cancer Centers. Integrative therapies within the cancer centers allow patients easy access to care before, during, or after their cancer treatment. In 2018, 15 of the 19 cancer clinics had integrative therapies available to patients with cancer. This model required unified operations, onboarding, training, competency, and clinical oversight to achieve consistent processes for consistent outcomes. Furthermore, these innovative models prioritized the following: patient access (easy and affordable); service delivery (consistent and operationalized); clinical outcomes (effective and meaningful); and caliber of clinician (competent and confident). Aurora Health Care employs massage therapists (Mts) and acupuncturists (Ats). This employment model allows for standards and program model adherence. To achieve competent and confident clinician's, MT or AT must complete a cancer treatment-focused competency training program relative to their respective profession and adherence to practice standards outlined. The training program is built on evidence-based practice, observation, direct demonstration, return demonstration, mentorship, and ongoing quality review by clinical leaders. Aurora's Integrative Cancer Care closed model of care is accessible to patients through philanthropic funds secured to underwrite the free service of MT provided during infusion treatments. Funds also provided three free AT sessions. Ongoing acupuncture therapies were provided at a low-cost group acupuncture fee at $25.00 per treatment. Acupuncture is available in group format and provided either before or after chemotherapy treatment. The free services were intended to introduce the concept of integrative therapies as a viable adjuvant option with conventional cancer care. As this model incorporates a mix of philanthropic funding and low-cost fees to offset the cost of the therapy provider, it is referred to as a "closed model" or accessible only to those patients under the care of an Aurora Cancer specialist. In 2018, 15 Aurora Cancer Clinics offered massage and 11 Aurora Cancer Clinics offered acupuncture. Patients who self-selected integrative therapies via system-employed Mts and Ats were surveyed pre/post acupuncture and MT treatments using a visual analog scale about their perceived levels of pain, stress, nausea, and neuropathy. The staff integrative clinicians collected data from patients, and post-treatment data were compiled by the Department of Integrative Medicine. Settings/Location: Aurora Cancer Centers are embedded within Aurora hospitals or free-standing clinics located throughout Wisconsin. In 2018, 15 cancer clinic locations embedded Mts, and 11 cancer clinic locations embedded Ats. Subjects: Oncology patients. Interventions: Clinical competencies were developed and applied to address indications, contraindications, and oncology-specific procedures to ensure that consistent quality of therapies was provided across sites. In 2018, Ats delivered 4367 Ats across 11 locations and Mts delivered 4197 Mts across 15 locations. During this study, the number of treatments provided was tracked versus episodic care. Outcome Measures: Pre/post AT and MT pain, stress, nausea, and neuropathy scores were recorded (0 [least] to 10 [worst]) and compared using paired t-tests. Results: Pre/post AT scores for pain, neuropathy, stress, and nausea were all significantly different (p < 0.001). For AT, there was a reported decrease in pain, stress, and neuropathy of 61.7%, 68.8%, and 47.9%, respectively. Pre/post MT scores for pain, neuropathy, nausea, and stress were also significantly different (p < 0.001). MT was greater at reducing stress and pain, 42.5% and 34.4%, respectively. Conclusions: Across 15 cancer clinics, both AT and MT treatments consistently and significantly reduced cancer-related side effects. These findings highlight the value of conducting a larger randomized-controlled trial to further assess the impact of Oncological Multisite Massage and Acupuncture Therapy on cancer-related symptoms across multiple oncologic clinics.

Electroacupuncture trigeminal nerve stimulation plus body acupuncture for chemotherapy-induced cognitive impairment in breast cancer patients: An assessor-participant blinded, randomized controlled trial

Chemotherapy causes various side effects, including cognitive impairment, known as 'chemobrain'. In this study, we determined whether a novel acupuncture mode called electroacupuncture trigeminal nerve stimulation plus body acupuncture (EA/TNS + BA) could produce better outcomes than minimum acupuncture stimulation (MAS) as controls in treating chemobrain and other symptoms in breast cancer patients. In this assessor- and participant-blinded, randomized controlled trial, 93 breast cancer patients under or post chemotherapy were randomly assigned to EA/TNS + BA (n = 46) and MAS (n = 47) for 2 sessions per week over 8 weeks. The Montreal Cognitive Assessment (MoCA) served as the primary outcome. Digit span test was the secondary outcomes for attentional function and working memory. The quality of life and multiple functional assessments were also evaluated. EA/TNS + BA treated group had much better performance than MAS-treated group on reverse digit span test at Week 2 and Week 8, with medium effect sizes of 0.53 and 0.48, respectively, although no significant differences were observed in MoCA score and prevalence of chemobrain between the two groups. EA/TNS + BA also markedly reduced incidences of diarrhoea, poor appetite, headache, anxiety, and irritation, and improved social/family and emotional wellbeing compared to MAS. These results suggest that EA/TNS + BA may have particular benefits in reducing chemotherapy-induced working memory impairment and the incidence of certain digestive, neurological, and distress-related symptoms. It could serve as an effective intervention for breast cancer patients under and post chemotherapy (trial registration: https://www.clinicaltrials.gov: NCT02457039).

Efficacy of Electroacupuncture on Treating Depression-Related Insomnia: A Randomized Controlled Trial

OBJECTIVE

To evaluate the efficacy of electroacupuncture (EA) on treating insomnia in patients with depression.

PATIENTS AND METHODS

In a patient-assessor-blind, randomized and sham controlled trial, 90 depression patients with insomnia were assigned into three different groups, receiving EA in the treatment group, superficial acupuncture at sham points in the control group A, or Streitberger non-insertion sham acupuncture in the control group B. Treatment was applied 3 times weekly for 8 consecutive weeks. The primary outcome was measured using the Pittsburgh Sleep Quality Index (PSQI). Secondary outcomes were sleep parameters including sleep efficiency (SE), total sleep time (TST) and numbers of sleep awakenings (SA) recorded in the actigraphy, as well as applying the Hamilton Rating Scale for Depression (HAMD-17), Self-Rating Depression Scale (SDS) and Hamilton Rating Scale for Anxiety (HAMA). Assessments were performed at the baseline (week 0), week 4, week 8, and week 12. Linear mixed-effects models were used for analyses and all statistical tests were two-sided.

RESULTS

Patients in the EA group had more significant improvement in PSQI scores than those in the control groups over time (respectively p<0.001 and p=0.04 for treatment and time interaction). At 8-week posttreatment, the EA group reported a reduction of -6.64 points in PSQI scores compared with -2.23 points in the control group A (95% CI= -5.74 to -2.39) and -2.94 points in the control group B (95% CI= -5.73 to -2.47). Compared with the two control groups, significant between-group differences were seen in SE (both p<0.01) and TST (both p<0.01) at week 8; similar results can be found in HAMD-17, SDS, and HAMA scores as well. However, there were no between-group differences in SA (respectively p=0.24 and p=0.08) after 8-weeks of treatment.

CONCLUSION

Electroacupuncture may improve the sleep quality of patients with depression.

Acupuncture Therapy in Post-Radiation Head-and-Neck Cancer with Dysgeusia

Background: Radiation therapy for head-and-neck cancer can cause side-effects, including pain, nausea, vomiting, sensory disorders such as anosmia and dysgeusia, dysphagia, xerostomia, hot flashes, fatigue, sleep disorders, and even anxiety and depression disorders. Therapies using acupuncture are now being adopted at cancer therapy centers. Acupuncture has been clinically proven to reduce the side-effects of cancer therapies, thus, resulting in better quality of life. Case: A 65-year-old man was diagnosed with stage I laryngeal squamous-cell carcinoma (SCC), and had missing taste and pain on swallowing (visual analogue scale [VAS]: 4) after undergoing 30 sessions of radiation therapy for head-and-neck cancer with a total radiation dose of 60 Gy. He received acupuncture at: body points (LI 4 Hegu, LR 3 Taichong, ST 36 Zusanli, SP 6 Sanyinjiao, and ST 40 Fenglong); the Battlefield Acupuncture points of the ear (Cingulate Gyrus, Thalamus, Zero Point, Shen Men, and Omega 2); and on the wrist area (according to a balance method). Acupuncture therapy was given 2 times a week, for 45-minute sessions. Results: After 12 acupuncture sessions, he had improvement in taste function and pain reduction from VAS 4 to VAS 1. This improvement likely occurred due to acupuncture's anti-inflammatory effects through anti-inflammatory mediator secretion, an antipain effect through ß-endorphin secretion, and nerve-cell regeneration through neurotropic factors' secretion. Conclusions: Routine acupuncture therapy can reduce dysgeusia and pain in postradiated patients with head-and-neck cancer. Acupuncture can be a therapeutic choice for patients with post-radiation head-and-neck cancer toxicity.

Efficacy of acupuncture in the prevention and treatment of chemotherapy-induced nausea and vomiting in patients with advanced cancer: a multi-center, single-blind, randomized, sham-controlled clinical research

Background

Chemotherapy-induced nausea and vomiting (CINV) is a common and distressing side effect. We conducted this clinical trial to compare the effectiveness of true acupuncture vs. sham acupuncture in controlling chemotherapy-induced nausea and vomiting (CINV) among patients with advanced cancer.

Methods

A total of 134 participants were randomly allocated into true acupuncture (TA) (n = 68) and sham acupuncture (SA) (n = 66) groups. Participants in both groups received acupuncture session twice on the first day of chemotherapy, and once consecutively on the following 4 days. The primary outcome was using the Common Terminology Criteria for Adverse Events (CTCAE) to assess CINV. The secondary outcome measures were the Eastern Cooperative Oncology Group score (ECOG), Simplified Nutritional Appetite Questionnaire (SNAQ), and Hospital Anxiety and Depression scale (HADS).

Results

Compared to the SA group, the TA group didn’t show significant improvement in complete response rates of chemotherapy-induced nausea and vomiting (all P > 0.05). However, the TA group could modestly reduce the severity of nausea (from day-3 to day-21, P < 0.05) or vomiting (from day-4 to day-21, P < 0.05), which is notably superior to the control group. Besides, TA promoted the nutritional status of patients with a significantly higher score comparing to the SA group on day 14 (21.82 vs.20.12, P = 0.003) and day 21 (22.39 vs. 20.43, P = 0.001). No apparent differences were found in anxiety and depression assessment between these groups. Participants in both groups were well tolerant of acupuncture therapy. There was no adverse event occurs in our study.

Conclusion

Acupuncture as an adjunctive approach could alleviate the severity of chemotherapy-induced nausea and vomiting compared to the sham control, even though the effect of acupuncture in preventing CINV occurring is relatively modest.

An Overview of Systematic Reviews: Complementary Therapies for Cancer Patients

Introduction: This article critically examines the systematic reviews (SR) and meta-analysis (MA) of complementary therapies for cancer patients to appraise the evidence level, and offers suggestions for future research and practice. Methods: The Cochrane Library and MEDLINE were searched from their inception to January 2018, to identify SR and MA of complementary therapies available for cancer patients. Final selected SR and MA were methodologically evaluated for their quality by applying the Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR2) instrument. Data extraction and risk of quality assessments were performed by 2 independent reviewers. Results: A total of 104 studies were included in the analysis. The majority of the individual clinical trials included in the SR and MA were performed in China (48%) and the United States (26.9%). Breast cancer was the most studied cancer type (25%), and acupuncture was the most studied intervention (21%). Side effects of cancer such as pain, depression, and fatigue were effectively managed with complementary therapies. The methodologically problematic items included not listing the excluded studies and lack of protocol or protocol registration. Conclusions: With increasing interest in research, complementary therapies appear to be beneficial in reducing side effects and raising the quality of life of cancer patients. Complementary therapies have generally been studied for all cancers, with acupuncture being the most researched, regardless of the cancer type. Since AMSTAR2 is a stricter assessment tool than before, future studies need to consider the risk of methodological bias with caution and discuss appropriate overall quality assessment tools.

Somatic Acupoint Stimulation for Cancer-Related Sleep Disturbance: A Systematic Review of Randomized Controlled Trials

Aim

The aim of this systematic review was to analyze and synthesize available evidence for the effects of somatic acupoint stimulation (SAS) on cancer-related sleep disturbance in adults with cancer.

Methods

Nine databases and four clinical trial registries were searched from their inception to July 2019 to identify potential articles and registered trials. Two authors independently extracted data and appraised the methodological quality of the included studies. The included studies could not be subjected to meta-analysis due to the significant variations in SAS intervention protocols and outcome measurement instruments. This systematic review therefore reported the results of the included trials narratively.

Results

Seven studies were identified, which involved 906 cancer patients. SAS protocols varied across trials without an optimal evidence-based standard intervention protocol to manage cancer-related sleep disturbance. Sanyinjiao (SP6) was the most commonly selected acupoint. Manual acupuncture was typically 15–30 min in duration and was conducted once a day or once a week for a period of 1–5 weeks, whereas self-administered acupressure was typically 1–3 min in duration per point and was conducted once a day, such as during night time before going to bed, for a period of 1–5 months. The results indicated that SAS could potentially relieve cancer-related sleep disturbance and improve quality of life. Mild adverse effects were reported in three of the included studies, but none of them performed a causality analysis to clarify the association between the reported adverse events and the intervention.

Conclusions

This systematic review showed that SAS is a useful approach to relieving cancer-related sleep disturbance. However, research evidence on SAS for managing cancer-related sleep disturbance has not been fully conclusive due to the limited number of existing clinical studies with relatively small sample size and suboptimal methodological quality. Clinical trials with large sample size and robust methodology are warranted in future research.

The Multidisciplinary Team (MDT) Approach and Quality of Care

The core function of a multidisciplinary team (MDT) is to bring together a group of healthcare professionals from different fields in order to determine patients' treatment plan. Most of head and neck cancer (HNC) units are currently led by MDTs that at least include ENT and maxillofacial surgeons, radiation and medical oncologists. HNC often compromise relevant structures of the upper aerodigestive tract involving functions such as speech, swallowing and breathing, among others. The impairment of these functions can significantly impact patients' quality of life and psychosocial status, and highlights the crucial role of specialized nurses, dietitians, psycho-oncologists, social workers, and onco-geriatricians, among others. Hence, these professionals should be integrated in HNC MDTs. In addition, involving translational research teams should also be considered, as it will help reducing the existing gap between basic research and the daily clinical practice. The aim of this comprehensive review is to assess the role of the different supportive disciplines integrated in an MDT and how they help providing a better care to HNC patients during diagnosis, treatment and follow up.

Research Advances on Acupuncture Analgesia

Pain is a widespread and complex symptom which causes serious emotional and social burdens to individuals and society. Most patients with pain rely heavily on over the counter (OTC) and prescription pain killers. However, there would be a number of issues that arise from the use of pain killers, in which safety and addiction are the most critical issues. For traditional Chinese medicine (TCM), pain is a result of the meridians being blocked. This could occur as a symptom of or be caused by various diseases. In this case, the key to relieve pain depends on dredging the meridian or meridians. Acupuncture has been practiced in China for over 2000 years to lessen pain. It is based on the “meridian theory”. Acupuncture is being used more widely and with a growing number of people in the treatment of pain because it is safer and has fewer side effects. Along with growing use and interest in acupuncture to treat pain, more attention has been paid to the mechanism underlying its analgesic effect, which is mainly associated with the changes of neurotransmitters. In this review, we summarize and analyze the range and mechanism of acupuncture analgesia treatment.

Acupuncture for the Relief of Chronic Pain: A Synthesis of Systematic Reviews

Background and Objectives: It is estimated that 28 million people in the UK live with chronic pain. A biopsychosocial approach to chronic pain is recommended which combines pharmacological interventions with behavioural and non-pharmacological treatments. Acupuncture represents one of a number of non-pharmacological interventions for pain. In the current climate of difficult commissioning decisions and constantly changing national guidance, the quest for strong supporting evidence has never been more important. Although hundreds of systematic reviews (SRs) and meta-analyses have been conducted, most have been inconclusive, and this has created uncertainty in clinical policy and practice. There is a need to bring all the evidence together for different pain conditions. The aim of this review is to synthesise SRs of RCTs evaluating the clinical efficacy of acupuncture to alleviate chronic pain and to consider the quality and adequacy of the evidence, including RCT design. Materials and Methods: Electronic databases were searched for English language SRs and meta-analyses on acupuncture for chronic pain. The SRs were scrutinised for methodology, risk of bias and judgement of efficacy. Results: A total of 177 reviews of acupuncture from 1989 to 2019 met our eligibility criteria. The majority of SRs found that RCTs of acupuncture had methodological shortcomings, including inadequate statistical power with a high risk of bias. Heterogeneity between RCTs was such that meta-analysis was often inappropriate. Conclusions: The large quantity of RCTs on acupuncture for chronic pain contained within systematic reviews provide evidence that is conflicting and inconclusive, due in part to recurring methodological shortcomings of RCTs. We suggest that an enriched enrolment with randomised withdrawal design may overcome some of these methodological shortcomings. It is essential that the quality of evidence is improved so that healthcare providers and commissioners can make informed choices on the interventions which can legitimately be provided to patients living with chronic pain.

Online information on oncologists' and non-medical practitioners' websites in Germany: A critical comparison

OBJECTIVE

To survey websites of oncologists and non-medical practitioners (NMPs) in Germany regarding range of treated symptoms, diagnostic tools and therapies offered to cancer patients as well as the quality of websites.

METHODS

Analysis of 98 websites of oncologists and NMPs was conducted between April and July 2018 with a standardized tool.

RESULTS

Range of diagnostic and therapeutic methods was high and differed between both groups. Many NMPs (65.3%) intended to support conventional therapy rather than to treat cancer. Most oncologists (85.7%) did not mention the role of complementary and alternative medicine (CAM). Texts on oncologists' websites, showed high complexity according to readability analysis using LIX score as opposed to those on NMPs websites that showed medium complexity. Only small difference of quality of websites between both groups could be detected.

CONCLUSION

Methods not acknowledged by evidence-based medicine as well as methods at risk for interaction with conventional cancer therapy but also treatment offers with potential benefits for cancer patients were found on NMPs websites.

PRACTICE IMPLICATIONS

As evidence-based CAM methods can be a useful support of cancer treatment, risk of herb drug interactions can be minimized by oncologists offering reasonable CAM.

Prophylactic acupuncture treatment during chemotherapy with breast cancer: a randomized pragmatic trial with a retrospective nested qualitative study

PURPOSE

This study investigated the effect of additional prophylactic acupuncture during chemotherapy on quality of life and side effects compared to standard treatment alone in breast cancer patients.

METHODS

In a pragmatic trial, newly diagnosed breast cancer patients were randomized to additional acupuncture treatments over 6 months or standard care alone (control group). The primary outcome was the disease-specific quality of life (FACT-B). Twenty qualitative semi-structured interviews were conducted with ten patients from each group regarding their subjective experiences.

RESULTS

A total of 150 women (mean age 51.0 (SD 10.0) years) were randomized. For the primary endpoint, FACT-B total score after 6 months, no statistically significant difference was found between groups (acupuncture: 103.5 (95%, CI 88.8 to 107.2); control (101.4 (- 97.5 to 105.4); difference 2.0 (- 3.4 to 7.5) p = 0.458)). Qualitative content analyses showed that patients in the acupuncture group described positive effects on psychological and physical well-being. For both patient groups, coping strategies were more important than reducing side effects.

CONCLUSIONS

Breast cancer patients receiving prophylactic acupuncture during chemotherapy did not show better quality of life in the questionnaires in contrast to the reported positive effects in the qualitative interviews. Coping strategies for cancer appear to be important.

Diffusional plasticity induced by electroacupuncture intervention in rat model of peripheral nerve injury

Electroacupuncture (EA) is an adjuvant therapy for peripheral nerve injury (PNI). Both peripheral and central alterations contribute to the rehabilitation process. We employed diffusion tensor imaging (DTI) to investigate the diffusion plasticity of afferent and efferent pathways caused by EA in model of peripheral nerve injury and reparation. Twenty-four rats were divided into three groups: normal group, model group and intervention group. Rats of the model group and the intervention group underwent sciatic nerve transection and anastomosis. EA intervention was performed on the intervention group at ST-36 and GB-30 for three months. Gait assessment and DTI were conducted at days post-operative (DPO) 30, 60 and 90. We selected corticospinal tract, spinothalamic tract and internal capsule as regions of interest and analyzed diffusion metrics including fractional anisotropy (FA), axial diffusivity (AD) and radial diffusivity (RD). FA values and RD values displayed significant differences or obvious tendency while AD values maintained a stable level. RD values displayed better indicative performance than FA in internal capsule. The intervention group presented significant correlation between RD values and Regularity Index (RI) during the intervention period. The effect of EA on peripheral nerve injury repairing rats appeared to be accelerated recovery process of sensory and motor neural pathway. We proposed that RD was a potential in vivo indicator for structural plasticity caused by EA and PNI.

Evidence, safety and recommendations for when to use acupuncture for treating cancer related symptoms: a narrative review

Background

Recently research on acupuncture for cancer related symptoms has significantly increased. To what extent have medical professionals recommended to use acupuncture in light of that evidence?

Methods

Evidence of effectiveness and safety was found by searching Pubmed for reviews to identify for what conditions and general results. Publications that recommend acupuncture in oncology were searched in the database of an ongoing general search for publications that recommend acupuncture. This database was developed by searching google for publications that recommend the use of acupuncture with the terms ‘name of symptom’ and ‘clinical practice guideline’ or ‘treatment guideline’.

Results

Acupuncture is moderately or weakly effective for 19 symptoms in patients with cancer and cancer survivors. Acupuncture is a safe therapy in cancer care if administered by trained acupuncturists. Acupuncture is targeted to improve symptoms associated with the cancer and different cancer treatments, not to treat the cancer itself. More than 350 publications by clinical practice guideline groups and expert groups, including public health statements made by national and government agencies recommended the use of acupuncture for 61 cancer related symptoms many with positive evidence of effectiveness.

Conclusion

The strength of evidence is weak for many indications, however the evidence for many standard therapies is either not very strong or if stronger, the incidence of adverse events is more, which makes acupuncture a treatment option despite the weak evidence. We have found evidence that many oncologists around the world have started to incorporate acupuncture into the treatment of various cancer related symptoms.

Hypoglossal acupuncture for acute chemotherapy-induced dysgeusia in patients with breast cancer: study protocol of a randomized, sham-controlled trial

Background

Distortion of taste sensations is a common chemotherapy-induced side effect; however, treatment evidence is limited. Pilot data indicated that acupuncture might be able to improve symptoms of dysgeusia. Thus, the aim of this study is to investigate the effects and side effects of hypoglossal acupuncture in the treatment of dysgeusia in patients with breast cancer undergoing chemotherapy.

Methods/design

The study is a randomized controlled trial comparing a single verum acupuncture treatment with two active comparators: sham acupuncture and dietary recommendations. Sample size calculation revealed a total of 75 patients pending an alpha of 0.05, a power of 0.8, and an estimated effect size of 0.80. Patients with breast cancer undergoing platinum- or taxane-based chemotherapy will be included if they present with phantogeusia (abnormal taste sensations without an external oral stimulus) with an intensity of 4 points or above on an 11-point numeric rating scale (NRS). The primary outcome is phantogeusia; secondary outcomes include parageusia (abnormal taste of food), hypogeusia (reduced taste sensations), hypergeusia (increased taste sensations), xerostomia (dry mouth), stomatitis, appetite, and functional impairment. All outcomes will be assessed at baseline and prior to the next chemotherapy administration using an 11-point NRS for each. All adverse events will be recorded.

Discussion

The results of this study will demonstrate the extent to which hypoglossal acupuncture may influence the intensity of and functional impairment due to chemotherapy-induced dysgeusia.

Electro-Acupuncture Promotes Accumulation of Paclitaxel by Altering Tumor Microvasculature and Microenvironment in Breast Cancer of Mice

Targeted drug delivery could increase the efficacy of chemotherapy, however, a plethora of obstacles exist in the current targeted delivery designs. In this study, we introduce a novel avenue of targeted drug delivery using electro-acupuncture and evaluate its effect on the distribution of paclitaxel in a breast cancer mouse model. Our results show that electro-acupuncture intervention significantly increased the intratumoral concentration of paclitaxel. The mice in acupuncture group showed shorter t_max, longer t_1/2 and higher AUC of paclitaxel as compared with that in paclitaxel-only group. Moreover, we found that the acupuncture intervention significantly induced cell apoptosis in tumors. The levels of COL IV and α-SMA increased in tumors of acupuncture group. The negative tumor metastasis biomarker, NM23, was significantly upregulated in tumors of mice in acupuncture group. Our results suggest that acupuncture intervention around the tumor area increases the local concentration of chemotherapeutic agents. The targeted effect of acupuncture is achieved by altering tumor microvasculature and microenvironment. Therefore, combined therapy of acupuncture with chemotherapeutic agents is promising in improving cancer treatment efficacy.

Assessment of the quality of reporting in studies of acupuncture for patients with cancer using the STRICTA guidelines

Introduction:

There has been a burgeoning of research evaluating acupuncture for various symptoms of cancer and the side-effects associated with its treatment. A systematic review was conducted to examine the quality of reporting in published studies of acupuncture in cancer according to the STRICTA (STandards for Reporting Interventions in Clinical Trials of Acupuncture) guidelines.

Methods:

Systematic review of published research of acupuncture for symptoms of cancer and the side-effects associated with its treatment. Databases searched were: Medline, CINAHL, Cochrane (all databases), Scopus, and PubMed from their inception to December 2014. Clinical trials, pilot/feasibility studies, observational studies, and case studies were included. Only full journal papers published in English were included. The quality of reporting was evaluated using STRICTA guidelines. Each included paper was assessed by two independent reviewers, with disagreements adjudicated by a third reviewer.

Results:

88 papers were identified which met the inclusion criteria. The median number of STRICTA items reported in trials with a control or comparator arm (n=47) was 14 out of 17 (range 8 to 17, IQR 4). For studies without a control or comparator arm the median was 11 out of a possible 15 (range 5 to 15, IQR 3). Key weaknesses in reporting included details of other components of treatments, and details of the acupuncturist administering treatments.

Conclusions:

Despite the widespread use of the STRICTA guidelines in acupuncture research, adherence remains poor for a few specific items. Further research is required to explore the reasons why authors fail to report those items, and to develop strategies to improve the adherence to the guidelines.

Traditional Chinese medicine for management of recurrent and refractory Crohn disease: A case report

INTRODUCTION

Crohn disease (CD) is a chronic relapsing systemic inflammatory disease afflicting the gastrointestinal system with a high morbidity. There has been increasing clinical interest in traditional Chinese medicine (TCM) treatment for CD. This report aims to present patient outcome of therapeutic management using TCM in combination with pharmacologic therapy.

PATIENT CONCERNS

A 53-year-old woman with a more than 23-year history of chronic indigestion, reflux, abdominal pain, and excessive diarrhea, and a more than 21-year history of recurrent refractory CD. The condition had been managed for 21 years with ongoing pharmacologic therapy, and surgical intervention; however, with poor therapeutic effect.

DIAGNOSIS

In this study, the diagnosis of CD was based on integrating patient symptoms and radiologic findings and biopsy results. The patient had no differential diagnosis.

INTERVENTIONS

The patient received acupuncture treatment at an approximate frequency of once per week for a total of 21 sessions until November 5, 2018. The patient also received Chinese herbal medicine (CHM) on an as-needed basis to manage her symptoms.

OUTCOMES

Patient reported symptoms of chronic indigestion, reflux, abdominal pain, and excessive diarrhea were substantially improved by combined TCM and pharmacologic therapy intervention, while the dosage of her medication was reduced.

CONCLUSION

Following acupuncture treatment, improvements of subjective symptoms: chronic indigestion, reflux, abdominal pain, and excessive diarrhea, were observed. CHM provided immediate relief of indigestion, reflux, and abdominal pain. TCM may be a potential therapeutic strategy to manage clinical symptoms of CD, if this is proven useful in future RCT studies.

Practical Perspectives in the Treatment of Nausea and Vomiting

Nausea and vomiting result from complex interactions between afferent and efferent pathways of the gastrointestinal tract, central nervous system, and autonomic nervous system. Afferent pathways from the vagus nerve, vestibular system, and chemoreceptor trigger zone project to nucleus tractus solitarius, which in turn relays signals to the central pattern generator to initiate multiple downstream pathways resulting in symptoms of nausea and vomiting. There is increasing evidence that the central pathway of chronic nausea is different from that of acute nausea and vomiting-and closely resembles that of neuropathic pain. This improved understanding of chronic nausea has resulted in a paradigm shift with regard to management strategy. Although conventional therapies such as antiemetics and prokinetics are commonly used to manage acute nausea and vomiting, they are historically not as effective in treating chronic nausea. Recently, neuromodulator agents, such as tricyclic antidepressants, gabapentin, olanzapine, mirtazapine, and benzodiazepines, and cannabinoids have been shown to be efficacious in the treatment of nausea and vomiting, and may be useful in the treatment of chronic symptoms. There is a need to study these agents, especially in the management of chronic functional nausea. Improved understanding of the central and peripheral circuitry of nausea and vomiting symptoms will allow for enhanced utilization of the currently available medications, and the development of novel therapeutic options.

The Association Between Different Patterns of Traditional Chinese Medicine Treatment and All-Cause Mortality Among Cancer Patients

Background: Cancer patients receiving Western medical treatment, frequently seek Traditional Chinese Medicine (TCM) to alleviate adverse effects and prolong survival. Objective: This study evaluated the association between the use of TCM and cancer survival rate. Research into the effect of TCM on patient survival is limited, this analysis focused on 3 patterns of TCM use. Methods: Three retrospective cohorts with different patterns of TCM use were selected from the National Health Insurance Research Database of Taiwan and analyzed. Patients with newly diagnosed cancer between 1997 and 2012 were classified into groups of prediagnosis, postdiagnosis, and continuous TCM use associated with awareness of cancer diagnosis. All demographic and clinical data were analyzed. Results: After propensity score matching, longevity of the postdiagnosis and continuous TCM user was significantly longer than the non-TCM user. The adjusted hazard ratios of death in postdiagnosis and continuous TCM use groups (0.59 and 0.61, respectively) were lower than the non-TCM use group. Conclusion: The analysis suggests that cancer patients using TCM in conjunction with Western medical treatment exhibited a higher survival rate than patients not using TCM treatment.

Oncology Acupuncture for Chronic Pain in Cancer Survivors: A Reflection on the American Society of Clinical Oncology Chronic Pain Guideline

Chronic pain syndromes associated with cancer treatment are common but difficult to manage. The American Society of Clinical Oncology recently published a practice guideline to address the unmet needs of cancer survivors, Management of Chronic Pain in Survivors of Adult Cancers, which stresses the importance of implementing integrative therapies including acupuncture. This review focuses on randomized clinical trials of acupuncture for chronic pain in cancer survivors, including its use in chemotherapy-induced peripheral neuropathy, aromatase inhibitor-associated arthralgia, and post neck dissection pain, and provides future directions of oncology acupuncture research in cancer survivorship. The features of oncology acupuncture are also discussed.

Ea versus Sham Acupuncture and no Acupuncture for the Control of Acute and Delayed Chemotherapy-Induced Nausea and Vomiting: A Pilot Study

Objective

To assess the feasibility of undertaking a high-quality randomised controlled study to determine whether EA gives better control of delayed chemotherapy-induced nausea and vomiting (CINV) than sham EA or standard antiemetic treatment alone.

Methods

Patients having their first cycle of moderately or highly emetogenic chemotherapy were randomised to EA, sham EA or standard care. EA was given for 30 min on day 1 at the time of chemotherapy and on day 3 using standard acupuncture points bilaterally. Sham EA was given to points adjacent to true EA points. All patients received usual care, comprising antiemetics, according to hospital guidelines. The primary outcomes related to study feasibility, and the clinical outcome measure was the change in Functional Living Index Emesis (FLIE) score captured on days 1 and 7.

Results

153 participants were screened between April 2009 and May 2011. Eighteen patients did not meet the inclusion criteria, 37 declined to participate and the absence of an acupuncturist or lack of consent from the treating oncologist excluded a further 38 patients; 60 patients were recruited. The FLIE was completed on day 7 by 49 participants; 33 of 40 patients returned on day 3 for treatment. The nausea and vomiting scores were low in all three arms. Adverse events were generally mild and infrequent.

Conclusions

It was feasible to undertake a randomised EA trial on a busy day oncology unit. As few patients experienced nausea with their first cycle of chemotherapy, it was not possible to determine whether EA improves CINV over standard care. An enriched enrolment strategy is indicated for future studies. A simple numerical rating scale may prove a better objective nausea measure than the FLIE.

The evaluation of changes in peripheral neuropathy and quality-of-life using low-frequency electrostimulation in patients treated with chemotherapy for breast cancer: a study protocol

BACKGROUND

Chemotherapy-induced peripheral neuropathy (CIPN) is a progressive, enduring, and sometimes irreversible neurotoxic symptom that occurs in 30-40% of chemotherapy-treated cancer patients. CIPN negatively affects both the patient's abilities to perform daily activities and their health-related quality of life (HRQOL) after chemotherapy treatment. Although this neuropathy has been treated with duloxetine and/or gabapentin, limited therapeutic benefits have been reported, thereby necessitating the development of an integrated approach that combines pharmacological management and complementary methods such as acupuncture and electric nerve stimulation. Therefore, this study is designed to examine the effect of a portable, low-frequency electrostimulation (ES) device on CIPN symptoms and HRQOL of female patients diagnosed with CIPN immediately after chemotherapy for breast cancer.

METHODS

This study is a single-center, randomized, placebo-controlled trial with two parallel groups and a 2-week follow-up. We will enroll 80 breast cancer patients who are newly diagnosed with CIPN after chemotherapy. Duloxetine or pregabalin will be prescribed to all participants from the initial assessment. Half of the patients will be assigned into the experimental group and the other half to the control group. The CarebandR (Piomed Inc., Seoul, Korea), a wearable wristband that generates low-frequency electrostimulation, will be administered only to the experimental group. Electrostimulation will be administered on the unilateral PC6 acupoint. A numerical rating scale will be used to assess the overall intensity of CIPN symptoms. The key secondary outcome variables include patient-reported CIPN symptom distress tested by a self-rated questionnaire, physician-rated symptom severity assessed by the Total Neuropathy Score, and HRQOL.

DISCUSSION

It is expected that the combination of a low-frequency electrostimulation device and pharmacological intervention (duloxetine or pregabalin) will produce synergistic effects in breast cancer patients with CIPN after treatment. To our knowledge, this is the first study to investigate the beneficial effect of a new integrated approach for CIPN management after breast cancer treatment. The study findings can expand our knowledge and understanding of the occurrence of CIPN and the efficacy of integrated intervention efforts to ameliorate CIPN symptoms.

Outpatient acupuncture effects on patient self-reported symptoms in oncology care: a retrospective analysis

Background: Increased access to complementary therapies such as acupuncture at academic medical centers has created new opportunities for management of cancer and cancer treatment related symptoms.

Methods: Patients presenting for acupuncture treatment during calendar year 2016 at an outpatient integrative medicine clinic in a comprehensive cancer center were asked to complete a modified Edmonton Symptom Assessment Scale (ESAS; 16 symptoms, score 0-10, 10 worst possible) before and after each visit. ESAS subscales analyzed included global (GDS; score 0-90), physical (PHS, 0-60) and psychological distress (PSS, 0-20). ESAS symptom score change pre/post acupuncture treatment & from baseline visit to first follow up were evaluated by paired t-test.

Results: Of 375 participants [mean age 55.6, 68.3% female, 73.9% white, most common cancer diagnosis of breast (32.8%) and thoracic/head & neck (25.9%)], 73.3% had at least one follow up acupuncture treatment [mean 4.6 (SD 5.1) treatments]. Highest/worst symptoms at baseline were poor sleep (3.92), fatigue (3.43), well-being (3.31), and pain (3.29). Statistically significant reduction/improvement (pre/post) was observed for all ESAS symptoms and subscales for the initial acupuncture treatment (p <0.001). Hot flashes had the highest mean reduction (-1.93), followed by fatigue (-1.72), numbness/tingling (-1.70), and nausea (-1.67). Clinically significant reductions were also observed for ESAS subscales of GDS (-12.2), PHS (-8.5), and PSS (-2.6). For symptom change from initial acupuncture treatment to first follow up (pre/pre), statistically and clinically significant improvement was observed for spiritual pain (-1.10; p<0.001) and ESAS subscale of GDS (-6.09; p=0.048). Clinical response rates (reduction ≥1) on follow up were highest for symptoms of spiritual pain (58.9%), dry mouth (57.8%) and nausea (57.3%).

Conclusions: Outpatient acupuncture was associated with immediate & longitudinal significant improvement across a range of symptoms commonly experienced by individuals during cancer care. Further research is needed to better understand frequency of treatments needed in clinical practice to help maintain benefit.

Acupuncture and Related Therapies for Treatment of Postoperative Ileus in Colorectal Cancer: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Delays in recovery of intestinal function following abdominal surgery are associated with longer hospital stays, increased postoperative complications, and higher costs to the health care system. Studies of acupuncture for postoperative ileus and other postoperative issues have reported improvements. This systematic review and meta-analysis aimed to assess whether acupuncture assisted recovery following surgery for colorectal cancer (CRC). Randomized controlled trials (RCTs) were identified from major English and Chinese language biomedical databases. Participants (aged 18 years plus) had received surgical resection for CRC. 22 studies (1,628 participants) were included. Five were sham-controlled. Outcomes included gastrointestinal function recovery (21 studies), recovery of urinary function (1 study), postoperative abdominal distension (3 studies), and quality of life (1 study). Meta-analyses found significant reductions in time to first bowel sounds, first flatus, and first defecation in both the sham-controlled and nonblinded studies. These results suggested that the addition of acupuncture following CRC surgery improved recovery of gastrointestinal function based on four blinded good quality RCTs (281 participants) and 17 nonblinded lower quality RCTs (1,265 participants). The best available evidence was for interventions that included electroacupuncture at the point ST36 Zusanli and there is supporting evidence for other types of acupuncture therapies that involve stimulation of this point. This review is registered with the following: systematic review registration in PROSPERO: CRD42017079590.

The National Cancer Institute's Conference on Acupuncture for Symptom Management in Oncology: State of the Science, Evidence, and Research Gaps

The Division of Cancer Treatment and Diagnosis, Office of Cancer Complementary and Alternative Medicine, at the National Cancer Institute (NCI) held a symposium on "Acupuncture for Cancer Symptom Management" on June 16 and 17, 2016. Invited speakers included 19 scientists and scholars with expertise in acupuncture and cancer research from the United States, Europe, and China. The conference reviewed the NCI's grant funding on acupuncture, analyzed the needs of cancer patients, reviewed safety issues, and assessed both the current scientific evidence and research gaps of acupuncture in oncology care. Researchers and stakeholders presented and discussed basic mechanisms of acupuncture; clinical evidence for specific symptoms; and methodological challenges such as placebo effects, novel biostatistical methods, patient-reported outcomes, and comparative effectiveness research. This paper, resulting from the conference, summarizes both the current state of the science and clinical evidence of oncology acupuncture, identifies key scientific gaps, and makes recommendations for future research to increase understanding of both the mechanisms and effects of acupuncture for cancer symptom management.

Overview of Treatment Guidelines and Clinical Practical Guidelines That Recommend the Use of Acupuncture: A Bibliometric Analysis

INTRODUCTION

As positive evidence emerges for the use of an intervention to treat a health problem, the intervention gradually becomes incorporated into treatment guidelines (TGs) or clinical practice guidelines (CPGs) that are related to that health problem. To assess whether this general hypothesis can apply to acupuncture, 96 health problems were identified for which positive conclusions in systematic reviews and meta-analyses regarding the effectiveness of acupuncture have been made and then searched for TGs or CPGs that have recommended the use of acupuncture.

METHODS

Through August 31, 2017, searches were performed in relevant medical databases and Google using "treatment guideline," "clinical practice guideline," and the names of the 96 medical conditions as search terms. A "snow-balling" search approach was adopted. All positive recommendations were added into the registry.

RESULTS

A total of 1311 publications were found that recommended using acupuncture published between 1991 and 2017. The number per year reached 50 in 2005 and 100 in 2009. In addition, 2189 positive recommendations were found for the use of acupuncture. Of these, 1486 were related to 107 pain indications and 703 were related to 97 nonpain indications. These recommendations were made by a wide range of groups, such as government health institutions, national guideline, and medical specialty groups. The recommendations came from around the world but were especially abundant in North America, Europe, and Australasia.

DISCUSSION AND CONCLUSION

Considerably more recommendations were found for the use of acupuncture than are known within the acupuncture or medical communities. A trend by year was also found; a rise in the number of positive statements about acupuncture was typically followed by a rise in the number of recommendations of acupuncture. Thus, the recommendations followed the emergent evidence for acupuncture. Better implementation plans need to be developed for the CPG/TG recommendations about acupuncture to be more effective/efficient.

Use of Complementary Traditional Chinese Medicines by Adult Cancer Patients in Taiwan: A Nationwide Population-Based Study

BACKGROUND

Many patients with cancer seek complementary and alternative medicine treatments. We investigated the use of traditional Chinese medicine (TCM) by adult cancer patients in Taiwan.

METHODS

We reviewed the Registry for Catastrophic Illness Patients Database of Taiwan, and included all adult patients diagnosed cancer, based on the International Classification of Diseases (ninth revision), from 2001 to 2009 and followed until 2011. This database allowed categorization of patients as TCM users (n = 74 620) or non-TCM users (n = 508 179). All demographic and clinical claims data were analyzed.

RESULTS

Compared with non-TCM users, TCM users were younger and more likely to be female, white-collar workers, and reside in highly urbanized areas. The average interval between cancer diagnosis and TCM consultation was 15.3 months. The most common cancer type was breast cancer in TCM users (19.4%), and intrahepatic bile duct cancer in non-TCM users (13.6%). The major condition for which TCM users visited clinics were endocrine, nutritional and metabolic diseases, and immunity disorders (23.2%). A total of 33.1% of TCM users visited TCM clinics more than 9 times per year and their time from diagnosis to first TCM consultation was 5.14 months. The most common TCM treatment was Chinese herbal medicine. The common diseases for which cancer patients sought TCM treatment were insomnia, malaise and fatigue, dizziness and headache, gastrointestinal disorders, myalgia and fasciitis, anxiety, and depression. Overall, TCM users had a lower adjusted hazard ratio (aHR) for mortality (aHR = 0.69, 95% CI = 0.68-0.70) after adjustment for age, sex, urbanization of residence, occupation, annual medical center visits, and annual non-medical center visits.

CONCLUSIONS

This study provides an overview of TCM usage among adult cancer patients in Taiwan. TCM use varied among patients with different types of cancer. Physicians caring for cancer patients should pay more attention to their patients' use of complementary TCM.

Looking Back, Looking Forward: The Ethical Framing of Complementary and Alternative Medicine in Oncology Over the Last 20 Years

This commentary takes a look back at views on complementary and alternative medicine and reflects on how those views have evolved, advocating for a conversation around complementary and alternative medicine in cancer care that is more nuanced, patient‐centered, and respectful to best meet the needs of patients in the coming decades.
