Introduction: Acupuncture has demonstrated effectiveness for symptom management among breast cancer survivors. This meta-analysis aims to evaluate the effect of acupuncture on treatment-related symptoms among breast cancer survivors. Methods: The authors searched PubMed, CINAHL, and EMBASE for relevant randomized clinical trials (RCTs) of acupuncture for managing treatment-related symptoms published in English through June 2021. They appraised the quality of each article using the Cochrane Collaboration Risk of Bias Criteria. The primary outcomes were pain, hot flashes, sleep disturbance, fatigue, depression, lymphedema, and neuropathy as individual symptoms. They also evaluated adverse events reported in acupuncture studies. Results: Of 26 selected trials (2055 patients), 20 (1709 patients) were included in the meta-analysis. Acupuncture was more effective than control groups in improving pain intensity [standardized mean difference (SMD) =-0.60, 95% confidence intervals (CI)-1.06 to-0.15], fatigue [SMD =-0.62, 95% CI-1.03 to-0.20], and hot flash severity [SMD =-0.52, 95% CI-0.82 to-0.22]. The subgroup analysis indicated that acupuncture showed trends but not significant effects on all the treatment-related symptoms compared with the sham acupuncture groups. Compared with waitlist control and usual care groups, the acupuncture groups showed significant reductions in pain intensity, fatigue, depression, hot flash severity, and neuropathy. No serious adverse events were reported related to acupuncture intervention. Mild adverse events (i.e., bruising, pain, swelling, skin infection, hematoma, headache, menstrual bleeding) were reported in 11 studies. Conclusion: This systematic review and meta-analysis suggest that acupuncture significantly reduces multiple treatment-related symptoms compared with the usual care or waitlist control group among breast cancer survivors. The safety of acupuncture was inadequately reported in the included studies. Based on the available data, acupuncture seems to be generally a safe treatment with some mild adverse events. These findings provide evidence-based recommendations for incorporating acupuncture into clinical breast cancer symptom management. Due to the high risk of bias and blinding issues in some RCTs, more rigorous trials are needed to confirm the efficacy of acupuncture in reducing multiple treatment-related symptoms among breast cancer survivors. © Copyright 2021, Mary Ann Liebert, Inc., publishers 2021.

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.

BACKGROUND: Many randomized controlled trials (RCTs) of acupuncture reveal no significant differences between acupuncture and so-called placebo acupuncture. There is a strong tendency to replace the term "placebo" by the term "sham," because any needling stimulates a certain physiological response. However, neither concept accounts for the great diversity of results in RCTs comparing verum acupuncture and sham (placebo) acupuncture. Some trials have shown little or no difference, while other studies have found statistically significant differences. OBJECTIVE: Verum acupuncture and sham (placebo) acupuncture may achieve similar results to the extent that they share active constituents. We identified these common active constituents as dermatomes: the segmental structure of the human body. In our study, we tested the hypothesis that the more verum and sham (placebo) acupuncture share the same dermatomes, the closer the clinical outcomes will be, and vice versa. METHODS: All major databases were searched for RCTs that tested acupuncture versus sham (placebo) acupuncture. The dermatome charts of Hansen and Schliack were used to verify verum and sham (placebo) needling locations. Reported clinical outcomes were assessed in relation to the percentage of overlap between the dermatomes stimulated by acupuncture and sham (placebo) acupuncture. RESULTS: Our literature search yielded a total of 1738 references. Thirty-four studies met the inclusion criteria. The effects of sham (placebo) acupuncture varied according to the dermatomes stimulated: high overlap with those stimulated by verum acupuncture resulted in almost identical efficacy, while low overlap resulted in significant differences in efficacy. Clinical outcomes were similar when verum acupuncture and sham (placebo) acupuncture shared the same dermatomes (p < 0.01). DISCUSSION: The findings of this review confirm our hypothesis. Acupuncture studies that employed verum and sham locations on overlapping dermatomes helped to create a mediocre to negative picture of acupuncture's efficacy. The segmental structure of the body with its interconnected reflex system offers an additional neurophysiological explanation for the effectiveness of acupuncture applied to structures segmentally innervated by the spinal and visceral nervous system. Further comparative acupuncture studies should be based on knowledge of segmental anatomy. In testing verum acupuncture versus sham acupuncture, the chosen sham acupuncture needling locations should be situated on non-overlapping dermatomes.

Background: Acupuncture has been used for many breast cancer treatment-related problems, but how long the effect lasts is unknown. This meta-analysis aims to evaluate how long the effect of acupuncture on breast cancer-related hot flushes and menopause symptoms lasts. Methods: The research design followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement, without language restrictions. Seven databases from inception through February 2019 were accessed; only randomized clinical trials (RCTs) that examined the maintenance effect of acupuncture on hot flushes or menopause symptoms after treatment were included. Cochrane criteria were followed and RevMan 5.2 software was used to analyze trials. Results: In total, 943 patients from 13 RCTs were analyzed. The meta-analysis showed that acupuncture had no significant long-term maintenance effect on the frequency or severity of hot flushes (p = 0.29; p = 0.34), but had a significant 3-month maintenance effect of ameliorating menopause symptoms at 3 months after treatment ended (p = 0.001). No adverse events were reported. Conclusions: Acupuncture significantly alleviated menopause symptoms for at least 3 months, but not hot flushes. Breast cancer patients concerned about the adverse effects of hormone therapy could consider acupuncture as an alternative. Additional acupuncture at 3 months after the initial treatment course could be considered. A large-scale study may help to define the optimal guideline for this issue.

The scientific evidence of acupuncture studies has been improved in recent years, and one of the important manifestations is that more and more acupuncture clinical trials and mechanism researches have been published in the source periodicals of Science Citation Index (SCI). This study summarized the dominant diseases of acupuncture focusing on of acupuncture efficacy and mechanisms, and discussed the existing problems, highlighting the direction of future developments. Most clinical studies were published in journals with journal impact factor (JIF) score of 10 or above, and majority of the basic researches had JIF scores of 5 to 10. The above literature were further divided according to the International Classification of Diseases (ICD). The most concerned diseases in these articles were neurological diseases, musculoskeletal system and connective tissue diseases, tumor and digestive system diseases. The therapeutic effect and mechanism of acupuncture on each kind of disease were summarized. The results showed that the therapeutic effect of acupuncture on nerve injury focused on the anti-oxidation pathway, neuroprotective and anti-inflammatory processes. The antiinflammatory effect also played an important role in the treatment of musculoskeletal diseases. The analgesic effect was underlined in most of these studies. Clinical trials were well carried out on acupuncture curative effect of tumor complications and side effects of chemo-radiotherapy, but the potential mechanisms have not been clarified. Somato-visceral reflex was suggested to be strongly associated with the effects of acupuncture changing the motor activity of the gastrointestinal tract. Functional magnetic resonance imaging studies indicated that non-specific effects play important roles in acupuncture analgesia. Lines of evidence have pointed out that the regulation of neuro-endocrine-immune networks may be a common switch of acupuncture on different nerve system diseases.

OBJECTIVE: To critically assess the effectiveness and safety of acupuncture for treating hot flashes (HFs) among breast cancer (BC) patients, and to get much more highly compelling evidence then to guide clinical practice. METHODS: Comprehensive systematic literature searches were carried out for identifying randomized controlled trials and observational studies (OSs) published before January 2015. The meta-analysis (MA) was performed by Review Manager 5 software if data could be merged routinely, if not descriptions would be given. RESULTS: A total of 18 studies were eligible ultimately. With respect to HFs frequency, the MA during treatment showed a significant difference (MD = -1.78, 95% confidence intervals [95% CIs]: -3.42--0.14), but no statistical differences were observed when posttreatment or follow-up period. While electroacupuncture versus applied relaxation, they both helped to promote HFs markedly but did not reveal statistically significance between them. Referring to Kupperman's index, all the treatment brought out great assistance when compared with baseline conditions, and there was significant difference between real acupuncture sham acupuncture (posttreatment: MD = -4.40, 95% CI: -6.77--2.03; follow-up: MD = -4.30, 95% CI: -6.52--2.08). In terms of OS, 7 prospective single arm studies focused on exploring the efficacy of traditional acupuncture, and all revealed moderate or great benefit for BC patients suffering from HFs. CONCLUSIONS: Acupuncture still appeared to be an efficacious therapeutic strategy, especially for the less/no side effects. Because of its widespread acceptance and encouraging effectiveness for improving HFs, much more high-quality studies are in need urgently.

IMPORTANCE: Acupuncture can help reduce unpleasant side effects associated with endocrine therapy for breast cancer. Nevertheless, comprehensive evaluation of current evidence from randomized controlled trials(RCTs) is lacking. OBJECTIVE: To estimate the efficacy of acupuncture for the reduction of hormone therapy-related side effects in breast cancer patients. EVIDENCE REVIEW: RCTs of acupuncture in breast cancer patients that examined reductions in hormone therapy-related side effects were retrieved from PubMed, EMBASE, Web of Science, Ovid MEDLINE, and Cochrane Library databases through April 2016. The quality of the included studies was evaluated according to the 5.2 Cochrane Handbook standards, and CONSORT and STRICTA (Revised Standards for Reporting Interventions in Clinical Trials of Acupuncture) statements. INTERVENTION: Interventions included conventional acupuncture treatment compared with no treatment, placebo, or conventional pharmaceutical medication. Major outcome measures were the alleviation of frequency and symptoms and the presence of hormone therapy-related side effects. Findings/Results. A total of 17 RCTs, including a total of 810 breast cancer patients were examined. The methodological quality of the trials was relatively rigorous in terms of randomization, blinding, and sources of bias. Compared with control therapies, the pooled results suggested that acupuncture had moderate effects in improving stiffness. No significant differences were observed in hot flashes, fatigue, pain, gastrointestinal symptoms, Kupperman index, general well-being, physical well-being, tumor necrosis factor (TNF), and interleukin (IL). CONCLUSIONS: Acupuncture therapy appears to be potentially useful in relieving functional stiffness. However, further large-sample trials with evidence-based design are still needed to confirm these findings.

Background. Insomnia is a prominent complaint of cancer patients that can significantly affect their quality of life and symptoms related to sleep quality. Conventional drug approaches have a low rate of success in alleviating those suffering insomnia. The aim of this systematic review was to assess the efficacy of acupuncture in the management of cancer-related insomnia. Methods. A total of 12 databases were searched from their inception through January 2016 without language restriction. Randomized controlled trials (RCTs) and quasi-RCTs were included if acupuncture was used as the sole intervention or as an adjunct to another standard treatment for any cancer-related insomnia. The data extraction and the risk of bias assessments were performed by 2 independent reviewers. Results. Of the 90 studies screened, 6 RCTs were included. The risk of bias was generally unclear or low. Three RCTs showed equivalent effects on the Pittsburgh Sleep Quality Index and 2 RCTs showed the similar effects on response rate to those of conventional drugs at the end of treatment. The other RCT showed acupuncture was better than hormone therapy in the numbers of hours slept each night and number of times woken up each night. The 3 weeks of follow-up in 2 RCTs showed superior effects of acupuncture compared with conventional drugs, and a meta-analysis showed significant effects of acupuncture. Two RCTs tested the effects of acupuncture on cancer-related insomnia compared with sham acupuncture. One RCT showed favourable effects, while the other trial failed to do so. Conclusion. There is a low level of evidence that acupuncture may be superior to sham acupuncture, drugs or hormones therapy. However, the number of studies and effect size are small for clinical significance. Further clinical trials are warranted.

BACKGROUND: Many breast cancer patients suffer from hot flush and medical menopause as side effects of treatment. Some patients undergo acupuncture, rather than hormone therapy, to relieve these symptoms, but the efficacy of acupuncture is uncertain. This meta-analysis evaluated the efficacy of acupuncture on hot flush and menopause symptoms in women with breast cancer. METHODS: A literature search was performed, following the PRISMA Statement and without language restrictions, of 7 databases from inception through March 2017. All selected studies were randomized clinical trials (RCTs) that examined the effect of needle acupuncture on hot flush and menopause symptoms in patients with breast cancer. The methodological quality of these trials was assessed using Cochrane criteria, and meta-analysis software (RevMan 5.2) was used to analyze the data. RESULTS: We examined 844 breast cancer patients (average age: 58 years-old) from 13 RCTs. The trials had medium-to-high quality, based on the modified Jadad scale. The meta-analysis showed that acupuncture had no significant effect on the frequency and the severity of hot flush (p = 0.34; p = 0.33), but significantly ameliorated menopause symptoms (p = 0.009). None of the studies reported severe adverse events. CONCLUSIONS: Acupuncture significantly alleviated menopause symptoms, but had no effect on hot flush. Breast cancer patients concerned about the adverse effects of hormone therapy should consider acupuncture. Further large-scale studies that also measure biomarkers or cytokines may help to elucidate the mechanism by which acupuncture alleviates menopause symptoms in patients with breast cancer.

CONTEXT: Most cancer patients suffer from both the disease itself and symptoms induced by conventional treatment. Available literature on the clinical effects on cancer patients of acupuncture, Tuina, Tai Chi, Qigong, and Traditional Chinese Medicine Five-Element Music Therapy (TCM-FEMT) reports controversial results. OBJECTIVES: The primary objective of this meta-analysis was to evaluate the effect of acupuncture, Tuina, Tai Chi, Qigong, and TCM-FEMT on various symptoms and quality of life (QOL) in patients with cancer; risk of bias for the selected trials also was assessed. METHODS: Studies were identified by searching electronic databases (MEDLINE via both PubMed and Ovid, Cochrane Central, China National Knowledge Infrastructure, Chinese Scientific Journal Database, China Biology Medicine, and Wanfang Database). All randomized controlled trials (RCTs) using acupuncture, Tuina, Tai Chi, Qigong, or TCM-FEMT published before October 2, 2014, were selected, regardless of whether the article was published in Chinese or English. RESULTS: We identified 67 RCTs (5465 patients) that met our inclusion criteria to perform this meta-analysis. Analysis results showed that a significant combined effect was observed for QOL change in patients with terminal cancer in favor of acupuncture and Tuina (Cohen's d: 0.21–4.55, <i>P</i> &lt; 0.05), whereas Tai Chi and Qigong had no effect on QOL of breast cancer survivors (<i>P</i> &gt; 0.05). The meta-analysis also demonstrated that acupuncture produced small-to-large effects on adverse symptoms including pain, fatigue, sleep disturbance, and some gastrointestinal discomfort; however, no significant effect was found on the frequency of hot flashes (Cohen's d = −0.02; 95% CI = −1.49 to 1.45; <i>P</i> = 0.97; I² = 36%) and mood distress (<i>P</i> &gt; 0.05). Tuina relieved gastrointestinal discomfort. TCM-FEMT lowered depression level. Tai Chi improved vital capacity of breast cancer patients. High risk of bias was present in 74.63% of the selected RCTs. Major sources of risk of bias were lack of blinding, allocation concealment, and incomplete outcome data. CONCLUSION: Taken together, although there are some clear limitations regarding the body of research reviewed in this study, a tentative conclusion can be reached that acupuncture, Tuina, Tai Chi, Qigong, or TCM-FEMT represent beneficial adjunctive therapies. Future study reporting in this field should be improved regarding both method and content of interventions and research methods. (PsycInfo Database Record (c) 2021 APA, all rights reserved)
