Chan YT, Wang N, Tam CW, Tan HY, Lu Y, So TH, Chau-Leung Yu E, Lao L, Feng Y. Systematic Review with Meta-Analysis: Effectiveness and Safety of Acupuncture as Adjuvant Therapy for Side Effects Management in Drug Therapy-Receiving Breast Cancer Patients. Evid Based Complement Alternat Med. 2021. [222725]. https://doi.org/10.1155/2021/9949777

Objective To investigate the potential benefits and safety of acupuncture on managing side effects induced by drug therapies in patients with breast cancer using a PRISMA standard systematic review and meta-analysis.
Methods Published randomised controlled trials from nine databases in English and Chinese language were searched. Trials with a real acupuncture treatment group and a control group with sham acupuncture, no treatment, or waitlist control were included. The primary outcome of this study was the therapeutic effects on five symptoms induced by drug therapies, including gastrointestinal disorder, neuropathy, arthralgia, joint symptoms, and cognitive impairment. The quality of life was assessed as a secondary outcome. The risk of bias of each study was analysed according to the Cochrane Handbook.
Results Sixteen randomised controlled trials with 1189 participants were included in the meta-analysis. The primary outcome and all subgroup analyses showed statistically significant improvements in the management of side effects by real acupuncture. The quality of life of patients has enhanced during the treatment.
Conclusion Although the number of publications is limited, a clear preliminary conclusion could be drawn by the meta-analysis, suggesting the beneficial adjuvant role of acupuncture in patients with breast cancer who receive drug therapies. No serious adverse events were observed from all the RCTs, and the safety of acupuncture is ascertained. More standardised and sophisticated large-scale randomised controlled trials are needed to evaluate the findings further.

Objective 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).
MethodsA 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.
ResultsOut 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.

Acupuncture as an adjuvant therapy for management of treatment-related symptoms in breast cancer patients: Systematic review and meta-analysis (PRISMA-compliant). Medicine (Baltimore). 2020;99(50). [216086]. doi

BackgroundAlthough randomized controlled trials have revealed the considerable effectiveness of acupuncture in breast cancer patients, there have been no studies exploring current acupuncture research trends for treatment induced various symptoms in breast cancer patients. This review evaluated the effectiveness of acupuncture for treatment-induced symptoms in breast cancer patients.
Methods We performed a systematic review and meta-analysis of the literature regarding acupuncture to treat symptoms associated with breast cancer therapies. The following databases were searched for relevant RCTs published before June 2018: MEDLINE, EMBASE, the Cochrane Library, AMED, CINAHL, OASIS, CNKI, and CiNii.
ResultsAmong the 19,483 records identified, 835 articles remained after screening titles and abstracts. A total of 19 RCTs were included in this qualitative synthesis. Among the studies, 8 explored climacteric symptoms, 4 explored pain, 2 explored lymphedemas, 2 explored nausea and vomiting and 3 investigated miscellaneous symptoms explored miscellaneous symptoms due to cancer treatments. Most of the studies reported that acupuncture can alleviate various symptoms of breast cancer treatment. However, there is a lack of evidence as to whether accupuncture can alleviate chemotherapy associated side effects
ConclusionsAcupuncture may alleviate the treatment-related symptoms of breast cancer; however, further studies are necessary to obtain conclusive evidence of the effectiveness of acupuncture in treating breast cancer.

Purpose To determine the efficacy of acupuncture on the management of hormone therapy-related side effects in breast cancer patients.
Methods Randomized controlled trials of acupuncture versus a control or placebo in breast cancer patients that examined reductions in therapy-related side effects were retrieved from PubMed, EMBASE, Web of Science, and the Cochrane Library through April 2020. Data on patient symptoms (hot flashes, fatigue, pain, stiffness, and gastrointestinal symptoms), physical capacity, cytokines, and general psychosomatic well-being were analyzed. We evaluated and analyzed the quality of all included studies with the 5.2 Cochrane Handbook standards using Stata software (version 10.0) and Revman software (version 5.2), respectively. We assessed the risk of bias using the Cochrane Risk of Bias tool and evaluated the quality of evidence using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) approach.
Results The pooled results suggested that acupuncture led to moderate improvements in hot flashes, fatigue, and stiffness. No significant differences were observed in pain, gastrointestinal symptoms, Kupperman index scores, Overall quality of life, tumor necrosis factor levels, and interleukin levels.
Conclusions Evidence for outcome indicators of symptom management were downgraded by the GRADE system for inconsistency, indirectness, and imprecision in the included RCTs. Nonetheless, acupuncture is a moderately appropriate alternative therapy for hormone therapy-related side effects in breast cancer patients. However, it still lacks large-sample, multicenter, prospective RCTs. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.

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.
Methods 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.

Kim TH, Kang JW, Lee MS. Current evidence of acupuncture for symptoms related to breast cancer survivors: A PRISMA-compliant systematic review of clinical studies in Korea. Medicine (Baltimore). 2018;97(32). [168683].

Background Breast cancer survivors experience various symptoms associated with their cancer interventions, and the benefits of acupuncture for these symptoms have been evaluated in clinical trials worldwide. The purpose of this review was to discuss the current status of clinical research regarding the use of acupuncture as a part of traditional Korean medicine (KM) for various symptoms associated with breast cancer therapies.
Methods We conducted a systematic review of the literature regarding the use of acupuncture as a part of traditional KM to treat symptoms associated with breast cancer therapies. The following databases were searched for content up to February 2017: MEDLINE, EMBASE, the Cochrane library, 4 Korean databases, and conference proceedings from major Korean medical societies.
ResultsAmong the 1228 identified articles, 8 observational studies (3 case series and 5 case reports), and 1 randomized controlled trial (RCT) were included in this review. Among these studies, 3 investigated lymphedema, 2 investigated chemotherapy-induced peripheral neuropathy, 1 investigated hot flushes, 1 investigated constipation, and 2 investigated miscellaneous symptoms in breast cancer survivors; all studies concluded that acupuncture can alleviate the symptom in question. However, we identified only 1 relevant RCT, and the included studies had limitations in terms of reporting quality.
ConclusionThere is a lack of conclusive evidence regarding the benefits of acupuncture for the treatment of breast cancer survivors in Korea. More rigorous RCTs are necessary in the future to establish stronger clinical evidence regarding the use of acupuncture to better reflect the clinical context of Korea.

Lee PL, Tam KW, Yeh ML, Wu WW. Acupoint stimulation, massage therapy and expressive writing for breast cancer: A systematic review and meta-analysis of randomized controlled trials. Complement Ther Med. 2016;:87-101. [186757].

OBJECTIVEA systematic review and meta-analysis were conducted to determine the effects on the quality of life, negative emotions and disease-related symptoms among women with breast cancer.
METHODS Two independent researchers performed a structured search using data sources including MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, PubMed and PsychINFO from the beginning of time until the first week of January 2015. A total of 23 acupoint stimulation, massage therapy and expressive writing RCTs were included in the review.
RESULTSThe study showed that no single intervention could be put under the spotlight exhibiting an overall effective result on all measured outcomes; however, looking into each one in detail shows different results in specific outcomes. Among the three interventions, acupoint stimulation has a treatment effect for general pain (MD=-1.46, 95% CI=-2.38 to -0.53) and fatigue (MD=-2.22, 95% CI=-3.68 to -0.77), massage therapy has a treatment effect for anxiety (MD=-0.50, 95% CI=-0.77 to -0.24), and expressive writing has a treatment effect for quality of life (MD=7.18, 95% CI=0.38 to 13.98). The measurement other outcomes showed either ineffective or equivocal results.
CONCLUSION Non-pharmacologic interventions including acupoint stimulation, massage therapy and expressive writing have an effect on a middle-age woman with breast cancer. However, because of limitations, the seemingly promising results should be interpreted with caution.

Background Although breast cancer treatment is associated with improved survival rates, it is also associated with numerous side effects, which can decrease overall quality of life for patients. Recent research indicates acupuncture may be useful in decreasing the incidence and duration of some side effects associated with cancer treatment.
Objective To assess the evidence surrounding the role of acupuncture in treating side effects associated with breast cancer treatment. Design: Systematic review based on search of PubMed, EMBASE (1996 to 2009 week 17), AMED (1985 to April 2009), and Ovid MEDLINE (1996 to April 2009) databases for relevant studies published up to April 2009. Authors of recent studies were contacted to determine if additional studies were taking place. Fourteen articles were independently appraised by 4 blinded reviewers.
Results Twelve studies met inclusion criteria: 9 investigated effects of traditional acupuncture and 3 addressed electroacupuncture. Seven different side effects were examined (hot flashes, fatigue, pain, dyspnea, psychological well-being, decreased range of motion with lymphedema, and emesis). The findings support the potential use of traditional acupuncture to decrease hot flashes, fatigue, and pain, whereas electroacupuncture may be useful in treating emesis and hot flashes. There is a paucity of high-quality evidence to support the use of acupuncture to treat dyspnea, emesis, and decreased range of motion with lymphedema or to improve psychological well-being.
Conclusion Current evidence suggests that traditional acupuncture may be useful in reducing hot flashes, fatigue, and pain, whereas electroacupuncture may be useful in treating emesis and hot flashes. Due to limitations in study designs and heterogeneity in treatment protocols, results should be viewed with caution and combined with clinical reasoning.

Objectifs The aim of the present study was to scrutinize the evidence on the use of acupoint stimulation for managing therapy-related adverse events in breast cancer.
Méthodes A comprehensive search was conducted on eight English and Chinese databases to identify clinical trials designed to examine the efficacy of acupressure, acupuncture, or acupoint stimulation (APS) for the management of adverse events due to treatments of breast cancer. Methodological quality of the trials was assessed using a modified Jadad scale.
Résultats Using pre-determined keywords, 843 possibly relevant titles were identified. Eventually 26 papers, 18 in English and eight in Chinese, satisfied the inclusion criteria and entered the quality assessment stage. The 26 articles were published between 1999 and 2008. They assessed the application of acupoint stimulation on six disparate conditions related to anticancer therapies including vasomotor syndrome, chemotherapy-induced nausea and vomiting, lymphedema, post-operation pain, aromatase inhibitors-related joint pain and leukopenia. Modalities of acupoint stimulation used included traditional acupuncture, acupressure, electroacupuncture, and the use of magnetic device on acupuncture points. Overall, 23 trials (88%) reported positive outcomes on at least one of the conditions examined. However, only nine trials (35%) were of high quality; they had a modified Jadad score of 3 or above. Three high quality trials revealed that acupoint stimulation on P6 (NeiGuang) was beneficial to chemotherapy-induced nausea and vomiting. For other adverse events, the quality of many of the trials identified was poor; no conclusive remarks can be made. Very few minor adverse events were observed, and only in five trials.
Conclusion APS, in particular acupressure on the P6 acupoint, appears beneficial in the management of chemotherapy-induced nausea and vomiting, especially in the acute phase. More well-designed trials using rigorous methodology are required to evaluate the effectiveness of acupoint stimulation interventions on managing other distress symptoms.

BackgroundBreast cancer (BC) is the most common cancer in women and is a serious threat to women's health. Cancer-related fatigue (CRF) is a distressing symptom in BC patients during and after chemotherapy or radiation therapy that severely affects quality of life (QoL). AT is widely used for fatigue management. However, the effect of AT on CRF is still uncertain. This study aimed to evaluate the efficacy and safety of AT in the management of CRF in patients with BC.
Methods Eleven databases were searched through June 2022. Two researchers independently performed the database search, study selection, data extraction, and risk of bias assessment. Study selection was performed based on predefined Participants, Intervention, Comparators, Outcomes, Study design (PICOS) criteria, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed when reporting the results. A meta-analysis was performed according to the Cochrane systematic review method using RevMan 5.3.
ResultsA total of 12 studies including a total of 1084 participants were included. The results showed that AT had a beneficial effect compared with sham AT (n = 256, SMD = -0.26, 95% CI [-0.51, -0.01], p = 0.04, I2 = 0%) and a long-term effect on fatigue score (n = 209, MD = -0.32, 95% CI [-0.59, -0.04], p = 0.02, I2 = 0%). Meta-analysis showed that AT had a beneficial effect compared with usual care (UC) on fatigue scores (n = 238, SMD = -0.39, 95% CI [-0.66 to -0.12], p = 0.005, I2 = 0%). Of the 12 articles, 3 articles were judged as having a low risk of bias in all domains and hence were of high quality. No serious adverse effects were identified.
ConclusionsAT is an effective and safe treatment for CRF, and AT is more effective than sham AT or UC or wait-list control (WLC). Nevertheless, the methodological quality of most of these studies was low, and the included studies/sample sizes were small, so the ability to derive decisive implications was limited. Further research is needed to confirm these findings.

Results The pooled results suggested that acupuncture led to moderate improvements in hot flashes, fatigue, and stiffness. No significant differences were observed in pain, gastrointestinal symptoms, Kupperman index scores, Overall quality of life, tumor necrosis factor levels, and interleukin levels.
Conclusions Evidence for outcome indicators of symptom management were downgraded by the GRADE system for inconsistency, indirectness, and imprecision in the included RCTs. Nonetheless, acupuncture is a moderately appropriate alternative therapy for hormone therapy-related side effects in breast cancer patients. However, it still lacks large-sample, multicenter, prospective RCTs. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.

Efficacy of physical therapy interventions on quality of life and upper quadrant pain severity in women with post-mastectomy pain syndrome: a systematic review and meta-analysis. Qual Life Res. 2022 Apr;31(4):951-973. https://doi.org/10.1007/s11136-021-02926-x

PurposeTo determine the efficacy of physical therapy interventions on quality of life (QoL) and pain severity in post-mastectomy pain syndrome (PMPS).
MethodsMultiple databases were searched from database inception to October 2020. Searches were limited to human studies published in either English or Chinese in peer-reviewed journals with full text available for randomized controlled trials conducted on females. Trials comparing the effectiveness of physical therapy interventions against control conditions on QoL and pain were included.
ResultsEighteen trials were included in the review. The pooled analysis of the four exercise trials revealed a significant effect of the intervention on general [standardized mean difference [SMD]: 0.87 (95%CI: 0.36, 1.37); p = 0.001], physical [SMD: 0.34 (95%CI: 0.01, 0.66); p = 0.044], and mental health components [SMD: 0.27 (95%CI: 0.03, 0.51); p = 0.027] of QoL compared with the control condition. Meta-analyses of six exercise trials, two myofascial release trials, and two acupuncture trials revealed a significant improvement in pain severity in the treatment group than in the control group. However, meta-analyses of two studies revealed a non-significant effect of compression therapy compared to control on pain severity.
ConclusionOur meta-analyses found that exercise is beneficial for improving the QoL and pain severity of women with PMPS. Future studies are needed to determine the optimal parameters for exercise interventions designed to improve QoL and pain severity in women with PMPS. The effect of acupuncture, myofascial release, and compression therapy remains inconclusive, and future research is required to validate the effect of these interventions on PMPS.

Purpose Breast cancer (BC) patients commonly face stress that causes severe psychological and physiological problems. The main objective of the review was to confirm the effect of interventions on breast cancer patients' perceived stress, and the secondary objective was to explore the impact of interventions on anxiety, depression, and inflammatory markers.
Methods A systematic and comprehensive search for randomized controlled trials (RCTs) that reported interventions' effects on perceived stress in breast cancer patients was performed in nine databases.
Results Twenty-four RCTs, including 1887 participants, met the inclusion criteria, summarizing six categories for the intervention group: mindfulness and yoga, exercise, cognitive-behavioral stress management, self-regulation, relaxation training, and acupuncture. Compared with usual care or other types of care, mindfulness and yoga had excellent effects against perceived stress, anxiety, and depression; self-regulation could reduce perceived stress and anxiety; exercise could reduce perceived stress; acupuncture could reduce the level of depression; mindfulness could improve the TNF-α level, and yoga can reduce the level of salivary cortisol and DNA damage.
Conclusion This systematic review indicated that nondrug interventions, such as mindfulness and yoga, effectively reduce perceived stress, anxiety, and depression. Rigorous studies with large sample sizes are needed to address the limitations of small sample sizes and shortcomings in methodology in this area.

ObjectivesThe application of systematic review (SR) has been increased rapidly in the field of cancer treatment. Complementary and alternative medicine (CAM) for cancer is no exception. The aim of this review is to evaluate and summarize systematic reviews on the CAM use in breast cancer patients.
MethodsSearch sources were Centre for Reviews and Dissemination (CRD), Cochrane Database of Systematic Reviews (CDSR), and PubMed. In addition, we assessed the quality of SR with the Assessing the Methodological Quality of Systematic Reviews (AMSTAR). This review did not consider control groups and outcomes.
ResultsThirty-four SRs met a set of criteria. According to interventions, there were twenty SRs which included yoga, acupuncture, and herbal medicines. Meta-analysis of 19 out of 34 reviews showed the followings: (1) acupuncture had a beneficial effect on the frequency of hot flushes, (2) yoga had a beneficial effect on depression and health-related QOL, (3) mindfulness-based stress reduction (MBSR) had a beneficial effect on anxiety and depression, (4) combination of herbal medicine and chemotherapy synergistically improved clinical outcomes, (5) acupuncture did not show significant effect on the severity of hot flushes and cancer-related pain, (6) yoga was unable to be confirmed as having an effect on cancer-related pain and physical well-being. Given the results of AMSTAR, 9 out of 34 reviews were of high quality and 3 reviews were deemed to be of low quality. In conclusion, since most SRs were at moderate or high-quality levels, CAM could be helpful for treating specific symptoms related to breast cancer.
