Acupuncture for breast cancer-related lymphedema: a randomized controlled trial

Exploring the mechanisms and current status of acupuncture in alleviating tumor metabolism and associated diseases: Insights from the central nervous system and immune microenvironment

Acupuncture, as a traditional Chinese medical treatment, has garnered increasing attention in recent years in fields such as tumor metabolism, the central nervous system, and the immune microenvironment. This paper aims to explore the fundamental principles, mechanisms, and research status of acupuncture therapy for tumor-related diseases. Firstly, we introduce the basic principles of acupuncture therapy, including the theories of meridians and its theoretical basis in tumor treatment. Secondly, we systematically review the mechanisms of acupuncture therapy for tumor-related diseases, discussing how acupuncture alleviates side effects such as pain, depression, fatigue, and gastrointestinal discomfort caused by conventional treatments through modulation of the immune microenvironment, central nervous system, and endocrine system. Subsequently, we discuss the current research status of acupuncture therapy for tumor-related diseases, as well as the application of current research methods and technologies in elucidating acupuncture mechanisms. Additionally, by combining clinical practice with different types of tumor-related diseases as experimental subjects, we demonstrate the application effectiveness and clinical practice experience of acupuncture in tumor treatment. Finally, a comprehensive assessment of acupuncture therapy for tumor-related diseases is provided, summarizing its limitations and prospecting future directions, including interdisciplinary collaboration and personalized treatment. In conclusion, acupuncture, as a feasible adjunctive therapy, is closely related to the central nervous system and the immune microenvironment, holding potential significant value in tumor treatment.

Acupuncture for the treatment of the pain-fatigue-sleep disturbance-numbness/tingling symptom cluster in breast cancer survivors: a feasibility trial

PURPOSE

Breast cancer survivors following disease-modifying treatment frequently experience multiple-concurrent symptoms (Jansana et al. in Int J Cancer 149(10):1755 1767, 2021), negatively impacting their quality of life and increasing the risk of polypharmacy (Alwhaibi et al. in J Oncol Pharm Pract 26(5):1052 1059, 2020). This study evaluates the feasibility and acceptability of acupuncture for the management of the pain-fatigue-sleep disturbance-numbness/tingling symptom cluster in breast cancer survivors, and investigates relationships between the symptom cluster and Traditional Chinese Medicine (TCM) syndrome diagnosis.

METHODS

This was a single-arm, pre-test/post-test feasibility trial conducted at Chris O'Brien Lifehouse Hospital, Australia. Breast cancer survivors who completed treatment and experienced clinically significant levels of two or more symptoms (pain, fatigue, sleep disturbance, numbness/tingling) were eligible to participate in the individualized, pragmatic 6-week acupuncture intervention. The primary outcome was feasibility and acceptability. Effectiveness was explored using a symptom cluster mean score.

RESULTS

Twenty women enrolled in the study over an 11-week period and 90% completed the study. Most women agreed or completely agreed that acupuncture was feasible (85%), acceptable (90%), and appropriate (90%). Both mean and composite symptom cluster scores were significantly reduced (p < 0.001), as were individual symptom scores in fatigue (p < 0.001), sleep disturbance (p = 0.04), and numbness/tingling (p = 0.01). TCM syndromes most closely associated with this symptom cluster were Spleen qi deficiency and Heart fire. No adverse events were reported.

CONCLUSION

This study demonstrated that acupuncture was safe and feasible, justifying a powered randomized control trial. Preliminary findings suggest beneficial effects of acupuncture for the management of the pain-fatigue-sleep disturbance-numbness/tingling symptom cluster for women with breast cancer. TCM syndromes identified in this trial may be used to guide acupuncture treatment protocols.

Conservative medical intervention as a complement to CDT for BCRL therapy: a systematic review and meta-analysis of randomized controlled trials

Background

The effect of first-line complex decongestive therapy (CDT) for breast cancer-related lymphedema (BCRL) depending on various factors forces patients to seek additional treatment. Therefore, this meta-analysis was conducted to evaluate the effect of different conservative medical interventions as a complement to CDT. This is the first meta-analysis that includes various kinds of conservative treatments as adjunctive therapy to get broader knowledge and improve practical application value, which can provide recommendations to further improve BCRL patients' health status.

Methods

RCTs published before 18 December 2023 from PubMed, Embase, Cochrane Library, and Web of Science databases were searched. RCTs that compared the effects of conservative medical intervention were included. A random-effects or fixed-effects model was used based on the heterogeneity findings. Study quality was evaluated using the Cochrane risk of bias tool.

Results

Sixteen RCTs with 690 participants were included, comparing laser therapy, intermittent pneumatic compression (IPC), extracorporeal shock wave therapy (ESWT), electrotherapy, ultrasound, diet or diet in combination with synbiotic supplement, traditional Chinese medicine (TCM), continuous passive motion (CPM), and negative pressure massage treatment (NMPT). The results revealed that conservative medical intervention as complement to CDT had benefits in improving lymphedema in volume/circumference of the upper extremity [SMD = -0.30, 95% CI = (-0.45, -0.15), P < 0.05, I 2 = 51%], visual analog score (VAS) for pain [SMD = -3.35, 95% CI (-5.37, -1.33), P < 0.05, I 2 = 96%], quality of life [SMD = 0.44, 95% CI (0.19, 0.69), P < 0.05, I 2 = 0], and DASH/QuickDASH [SMD = -0.42, 95% CI (-0.70, -0.14), P < 0.05, I 2 = 10%] compared with the control group. Subgroup analysis revealed that laser therapy and electrotherapy are especially effective (P < 0.05).

Conclusion

Combining conservative medical interventions with CDT appears to have a positive effect on certain BCRL symptoms, especially laser therapy and electrotherapy. It showed a better effect on patients under 60 years old, and laser therapy of low to moderate intensity (5-24 mW, 1.5-2 J/cm2) and of moderate- to long-term duration (≥36-72 sessions) showed better effects.

Acupuncture techniques and acupoints used in individuals under chemotherapy or radiotherapy treatment of cancer: A systematic review

AIMS AND OBJECTIVES

To describe the main acupuncture techniques and parameters that have been used in the most varied symptoms of different types of cancer.

BACKGROUND

Clinical evidence about the potential effectiveness of acupuncture and related therapies to control signs and symptoms associated with cancer or its treatment has been in several studies. Currently, there is already evidence of the use of acupuncture for the treatment of nausea and vomiting, fatigue, dry mouth, anxiety, depression, insomnia and pain. However, many studies lack firm rights or reproducible guidelines for treatment.

DESIGN

This study performs a systematic review of clinical trials related to the topic, based on the PRISMA protocol. Thus, a search was carried out in the Scopus, Pubmed and Web of Science databases, covering studies since January 2007.

METHODS

Structured and organised according to PICO standards, using keywords ("cancer" OR "malignant tumour" OR "chemotherapy" OR "radiotherapy") AND ("acupuncture" OR "electroacupuncture") AND ("pain" OR "nausea" OR "vomit" OR "fatigue" OR "xerostomia" OR "insomnia" OR "depression" OR "neuropathy").

RESULTS

After the selection and evaluation phase, 23 studies were included and analysed.

CONCLUSION

Based on this analysis, it is concluded that acupuncture is safe and there is evidence of the reduction of gastrointestinal symptoms, chemotherapy-induced peripheral neuropathy, pain, dry mouth, fatigue, insomnia, and improvement of cognitive capacity.

RELEVANCE TO CLINICAL PRACTICE

Acupuncture treatments could act by minimising the side effects of conventional treatments and reducing symptoms induced by tumours.

NO PATIENT OR PUBLIC CONTRIBUTION

The patients had no direct involvement with the study in question.

Acupuncture Treatment for Breast Cancer-Related Lymphedema: A Randomized Pilot Study

Background: Methods of conservative management for breast cancer-related lymphedema (BCRL) are burdensome in terms of time, cost, and convenience. In addition, many patients are not candidates for surgical treatment. Preliminary results have demonstrated possible beneficial effects of acupuncture for patients with BCRL. In this small pilot study, we examined the safety and feasibility of an acupuncture randomized control trial (RCT) in this patient cohort, utilizing a battery of standardized clinical and patient-centered outcome measures. Methods and Results: Patients with BCRL were randomized 2:1 to the acupuncture (n = 10) or the control (n = 4) group. Patients received acupuncture to the unaffected extremity biweekly for 6 weeks. Feasibility was defined as enrollment ≥80%, completion of ≥9 of 12 acupuncture sessions per person, and ≥75% completion of three of three measurement visits. To inform a future adequately powered RCT, we describe within-group changes in patient-centered outcomes, including circumferential measurements, bioimpedance spectroscopy, perometry, cytokine levels, and patient quality of life. Adverse events were systematically tracked. Fourteen patients completed the study. Of those who received acupuncture (n = 10), 8 completed all 12 acupuncture sessions, and 2 patients completed 11 sessions. Ninety-three percent of all participants completed all three measurement visits. There was no consistent improvement in arm volumes. Inflammatory marker levels had inconclusive fluctuations among both groups. All patients receiving acupuncture demonstrated an improvement in their functional quality-of-life score. No severe adverse events occurred. Conclusions: A randomized controlled study of acupuncture for BCRL is feasible. The acupuncture intervention is acceptable in this population, without safety concerns in a small sample and warrants further investigation.

Prevalence of late and long-term effects of cancer (treatment) and use of complementary and alternative medicine in Norway

BACKGROUND

The increasing number of patients surviving cancer leads to more people experiencing late and long term-effects from the disease and its treatment. Fatigue, sleep disorders, early menopause, pain, and nerve damage are commonly reported. Methods helping people to recover after cancer treatment are therefore essential. The aims of this study were threefold; (1) to determine the level of cancer patients suffering from late and long-term effects of cancer diagnosis and treatment in Norway, (2) explore complementary and alternative medicine (CAM) modalities used for managing these adversities, and (3) describe self-perceived benefits and harms of the CAM interventions.

METHODS

The study was conducted in cooperation with the Norwegian Cancer Society (NCS) and consisted of an online cross-sectional study among members of the NCS user panel with present or previous cancer (n = 706). The study was carried out in September/October 2021 using a modified cancer-specific version of the International Questionnaire to Measure Use of Complementary and Alternative Medicine (I-CAM-Q). A total of 315 women and 153 men agreed to participate, resulting in a response rate of 67%.

RESULTS

Most of the participants (83%) suffered from late and long-term effects of cancer treatment; mostly fatigue (59.2%), sleep disorder (41.5%), hot flashes (39.2%), nerve damage (polyneuropathy, 38.0%), and pain (36.6%) with a mean number of 5.1 different late and long-term effects. Late and long-term effects were positively associated with younger age and college/university education. Nearly half of the participants experiencing late and long-term effects (43%) reported having used CAM to treat these complaints. Most frequently used were self-help practices (26%) such as relaxation therapy (19%), yoga (14%) and meditation (13%), but also visits to CAM providers were reported by 22%. Herbal- and other natural remedies to treat late and long-term effects were used by 13%. A high percentage of CAM users reported self-perceived improvements of their symptoms (86% for self-help practices, 90% for visits to CAM providers). Few experienced adverse effects of the CAM treatment.

CONCLUSION

A large proportion of cancer patients suffered from a wide range of late and long-term effects of cancer diagnosis and treatment, and they use CAM to treat these complaints to a rather high degree. Relaxation therapy, yoga, meditation, massage, and acupuncture were the most frequently used therapies regardless of complaint. The therapies used are generally considered to be both safe and beneficial for the respective complaint, indicating that the participants seem to be well informed about the choices they make.

Symptom Management and Quality of Life of Breast Cancer Patients Using Acupuncture-Related Therapies and Herbal Medicine: A Scoping Review

Simple Summary

This is a scoping review of published literature on the usefulness of acupuncture-related therapies and herbal medicine in alleviating the side effects associated with breast cancer treatments. It is an important study given that the various treatment interventions for breast cancer, such as surgery, chemotherapy, radiotherapy, and hormone therapy, have unpleasant side effects that compromise the patient’s quality of life. The study revealed positive impact of some acupuncture-related therapies and herbal medicines in improving the symptoms and quality of life of patients with breast cancer. These findings will inform further studies on the economic impact of acupuncture and herbal medicines in the management of adverse events in patients on breast cancer treatment.

Abstract

The side effects associated with breast cancer treatments often reduce the patients’ quality of life. The effectiveness of acupuncture-related therapies and herbal medicine in managing the side effect is not fully understood. The study included clinical studies published in the 10 years since 2011 and analyzed the effectiveness of the therapies for managing side effects of anticancer treatment. The databases of MEDLINE via PubMed, CENTRAL, EMBASE, OASIS, and NSDL were searched. Thirty studies, including 13 (43.3%) randomized controlled trials (RCTs), 12 (40.0%) before-and-after studies, three (10.0%) case series, one (3.3%) case report, and one (3.3%) non-RCT, were included in this review. The main symptoms identified were aromatase inhibitors-induced arthralgia (AIA), lymphedema, and chemotherapy-induced peripheral neuropathy (CIPN). The types of acupuncture-related therapies applied included manual acupuncture, electro-acupuncture, moxibustion, and electro-moxibustion. In ten studies, eight herbal medications were administered. The Brief Pain Inventory-Short Form (BPI-SF) and Functional Assessment of Cancer Therapy-General (FACT-G) and -Breast (FACT-B) were frequently used to evaluate pain and QoL, respectively. Most studies suggested beneficial effects of acupuncture and herbal medicine on managing pain, daily function, and quality of life in patients going through AIA, CIPN, and/or lymphedema, with mild side effects. The scoping review implies the potential of CAM therapies as promising interventions for managing symptoms which otherwise lack alternative management options, and for improving the quality of life of breast cancer patients.

Safety of acupuncture in oncology: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Acupuncture is frequently used to treat the side effects of cancer treatment, but the safety of this intervention remains uncertain. The current meta-analysis was conducted to assess the safety of acupuncture in oncological patients.

METHODS

The PubMed, Cochrane Central Register of Controlled Trials, and Scopus databases were searched from their inception to August 7, 2020. Randomized controlled trials in oncological patients comparing invasive acupuncture with sham acupuncture, treatment as usual (TAU), or any other active control were eligible. Two reviewers independently extracted data on study characteristics and adverse events (AEs). Risk of bias was assessed using the Cochrane Risk of Bias Tool.

RESULTS

Of 4590 screened articles, 65 were included in the analyses. The authors observed that acupuncture was not associated an with increased risk of intervention-related AEs, nonserious AEs, serious AEs, or dropout because of AEs compared with sham acupuncture and an active control. Compared with TAU, acupuncture was not associated with an increased risk of intervention-related AEs, serious AEs, or drop out because of AEs but was associated with an increased risk for nonserious AEs (odds ratio, 3.94; 95% confidence interval, 1.16-13.35; P = .03). However, the increased risk of nonserious AEs compared with TAU was not robust against selection bias. The meta-analyses may have been biased because of the insufficient reporting of AEs in the original randomized controlled trials.

CONCLUSIONS

The current review indicates that acupuncture is as safe as sham acupuncture and active controls in oncological patients. The authors recommend researchers heed the CONSORT (Consolidated Standards of Reporting Trials) safety and harm extension for reporting to capture the side effects and better investigate the risk profile of acupuncture in oncology.

LAY SUMMARY

According to this analysis, acupuncture is a safe therapy for the treatment of patients with cancer. Acupuncture seems to be safe compared with sham acupuncture and active controls.

Effects of Acupuncture and Moxibustion on Breast Cancer-Related Lymphedema: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objective:

The aim of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to evaluate the effects of acupuncture and moxibustion (AM) in women with breast cancer-related lymphedema (BCRL).

Methods:

We retrieved RCTs published before January 24, 2021, from the MEDLINE, EMBASE, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Chongqing VIP (VIP), and Wanfang databases. RCTs that compared acupuncture and/or moxibustion intervention with other treatments were included. A random effects or fixed effects model was used based on the heterogeneity findings. Study quality was evaluated using the Cochrane risk of bias tool.

Results:

We included 14 RCTs in the analyses, of which 4 RCTs adopted acupuncture, 4 RCTs used moxibustion, and the rest used both. AM significantly reduced arm circumference at the elbow crease compared to routine care (Mean deviation (MD) = −7.26, 95% confidence interval (CI) = −8.30 to −6.21, P < .00001). There was a significant difference between AM and diosmin tablets in the effective index for upper limb lymphedema (MD = 24.68, 95% CI = 24.82-30.53, P < .00001), the range of motion of the shoulder during protraction (MD = 6.77, 95% CI = 2.81-10.73, P = .0008), and adduction (MD = 4.17, 95% CI = 1.02-7.32, P = .01). There was a significant difference between moxibustion and pneumatic circulation (MD = −0.51, 95% CI = −0.85 to −0.17, P = .003) in the visual analog score (VAS) for swelling. Finally, compared to the blank control, acupuncture reduced the VAS for pain (MD = −1.33, 95% CI = −1.52 to −1.15, P < .00001; heterogeneity (I²) = 0%, P = .57).

Conclusion:

Our results suggest that AM is effective in the treatment of BCRL. AM may reduce arm circumference at the elbow crease (compared to routine care), increase effective index for upper limb lymphedema (compared to oral diosmin tablets), improve the range of motion of the shoulder during protraction and adduction (compared to oral diosmin tablets), and decrease the VAS for both swelling (compared to pneumatic circulation) and pain (compared to blank control).

Acupuncture Improves Multiple Treatment-Related Symptoms in Breast Cancer Survivors: A Systematic Review and Meta-Analysis

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.

Research Trends of Acupuncture Therapy on Cancer Over the Past Two Decades: A Bibliometric Analysis

Purpose:

Acupuncture has been used for managing cancer-related symptoms. However, there are still few studies concerning the overall trends in acupuncture therapy on cancer based on bibliometric analysis. This study aims to demonstrate the current status and trends in this field over the past 2 decades.

Methods:

Articles were retrieved from the Web of Science from 2000 to 2019. CiteSpace was used for co-authorship network of countries/institutions, dual-map analysis, and detecting the keywords with citation bursts. VOSviewer was used to construct networks based on co-authorship and co-citation analysis of authors, and co-occurrence of keywords.

Results:

A total of 927 articles and reviews were included in the final analysis. The number of publications has steadily increased with some fluctuations among years. The country and institution contributing most to this field are the USA and Memorial Sloan Kettering Cancer Center. Mao JJ was the most productive author and Molassiotis A ranked first in the cited authors. The co-occurrence analysis revealed 5 clusters (including “clinical trials,” “clinical studies on chemotherapy/radiation-induced symptoms,” “CAM therapy for cancer,” “clinical studies on vasomotor symptoms,” and “systematic reviews”). Most recent keyword bursts were “neuropathic pain,” “arthralgia,” “prevention,” “supportive care,” and “integrative medicine”.

Conclusions:

The annual publication output would increase rapidly in the next decade, which shows a promising future in this research field. Future research hotspots would focus on the role of acupuncture in neuropathic pain, arthralgia, prevention, supportive care, and integrative medicine.

The use of acupuncture for advanced cancer care: Protocol for a systematic review and meta-analysis

AIM

To assess the up-to-date evidence of acupuncture for the management of cancer-related and cancer treatment-related outcomes among people with advanced cancer.

DESIGN

Systematic review with meta-analyses involving multidimensional outcomes.

METHODS

The protocol of this systematic review has been registered in PROSPERO with the registration number CRD42020212982. Six databases (including Pubmed, EMBASE, Cochrane Library, SinoMed, ClinicalTrials.gov and Chinese Clinical Trial Registry) will be searched from inception through November 2020 to identify relevant interventional trials examining acupuncture management on multidimensional outcomes in patients with advanced cancer. Main outcomes will include cancer and treatment-related symptoms, quality of life, sleep quality and adverse events. DerSimonian & Laird random-effects meta-analysis will be applied to calculate pooled relative risks for binary data and pooled weighted mean differences (WMDs) or standardized mean differences (SMDs) for continuous data. Trial quality ratings and risk of bias will be evaluated using the Cochrane Risk of Bias Tool and the Grading of Recommendations Assessment, Development and Evaluation approach.

DISCUSSION

The efficacy of acupuncture on advanced cancer care and outcomes has not yet been determined. Palliative care for patients with advanced cancer may involve multiple challenges that include physical and mental health care. This systematic review will offer updated and comprehensive evidence of acupuncture on specific outcomes induced by advanced cancer and cancer-related treatment, which can give high level clinical recommendations to improve patient care and clinical outcomes.

Acupuncture as an adjuvant therapy for management of treatment-related symptoms in breast cancer patients: Systematic review and meta-analysis (PRISMA-compliant)

BACKGROUND

Although 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.

RESULTS

Among 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 CONCLUSIONS:: Acupuncture 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.

Interventions for Breast Cancer-Related Lymphedema: Clinical Practice Guideline From the Academy of Oncologic Physical Therapy of APTA

A work group from the American Physical Therapy Association (APTA) Academy of Oncologic Physical Therapy developed a clinical practice guideline to aid clinicians in identifying interventions for people with breast cancer-related lymphedema, targeting volume reduction, beginning at breast cancer diagnosis and continuing through cancer treatments and survivorship. Following a systematic review of published studies and a structured appraisal process, recommendations were developed to guide physical therapists and other health care clinicians in their intervention selection. Overall, clinical practice recommendations were formulated based on the evidence for each intervention and were assigned a grade based on the strength of the evidence. The evidence for each specific intervention was synthesized and appraised by lymphedema stage, when the information was available. In an effort to make recommendations clinically applicable, they were presented by modality throughout the care trajectory. Methodology and research populations varied significantly across studies, and it will be important for future research to use standardized definitions for participant characteristics, diagnostic criteria, and interventions.

Effectiveness and Safety of Acupuncture Moxibustion Therapy Used in Breast Cancer-Related Lymphedema: A Systematic Review and Meta-Analysis

Objective

To evaluate the effectiveness and safety of acupuncture moxibustion therapy (AMT) for the breast cancer-related lymphedema (BCRL).

Methods

Four English databases (MEDLINE, PubMed, Embase, and Cochrane CENTRAL) and four Chinese databases were searched from their inception to Feb 1, 2020. Eligible randomized controlled trials (RCTs) investigating AMT against any type of controlled intervention in patients for BCRL and assessing clinically relevant outcomes (total effective rate, circumference difference, and Karnofsky performance score) were included. The methodological quality of all selected trials was estimated in accordance with the guidelines published by the Cochrane Collaboration. Review Manager 5.3 was used to conduct analyses.

Results

Twelve eligible RCTs are confirmed. Most of the trials selected are regarded as low methodological quality. Compared with Western medicine, physiotherapy, and functional training, traditional AMT has significantly higher treatment effect (RR 1.03 (95% CI: 1.22, 1.45); p < 0.00001). In comparison with physiotherapy, AMT is better in reducing edema symptoms (MD = −0.77; 95% CI (−1.13–0.41); p < 0.00001). Moreover, pooled results demonstrate that AMT results in better outcomes than functional training and Western medicine in improving Karnofsky performance score of BCRL patients (SMD = 0.69; 95% CI (0.38–1.00); p < 0.00001).

Conclusion

This systematic review and meta-analysis provides evidence that AMT is serviceable and safe in treating BCRL. With the limited number of available studies and methodology drawbacks, further high-quality RCTs with reasonable designs are still warranted.

The Effect of Acupuncture in Breast Cancer-Related Lymphoedema (BCRL): A Systematic Review and Meta-Analysis

Background: Breast cancer–related lymphedema (BCRL) is hard to control. Management may include lymphatic drainage, skin care, bandaging, or even surgery. Since acupuncture has been proven to affect the neurophysiology and neuroendocrine systems, it has the potential to control BCRL. Aim: To evaluate the effect of acupuncture in BCRL in randomized controlled trials. Design: A literature search was performed, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement and without language restrictions. Data Sources: Five databases were searched from inception tthrough September 2018. Only studies that fulfilled the eligibility criteria of evaluating the effect of acupuncture on lymphedema in breast cancer were included. The methodological quality of these trials was assessed using the Cochrane criteria, and meta-analysis software (RevMan 5.3) was used for analysis. Results: We examined 178 breast cancer patients from 6 trials. All included randomized controlled trials had medium to high quality, based on the modified Jadad scale. The systematic review showed that acupuncture is safe and has a trend to improve symptoms, but trials did not consistently measure outcomes. The meta-analysis showed that acupuncture produced no significant improvement in the extent of lymphedema as compared with the control intervention (−1.90; 95% confidence interval = −5.39 to 1.59, P = .29). None of the studies reported severe adverse events. Conclusions: Acupuncture is safe and has a trend to improve the lymphedema related to breast cancer, yet it did not significantly change arm circumference in BCRL. Future studies should include both subjective and objective measurements and large-scale studies are warranted.

Electronic Moxibustion for Breast Cancer-Related Lymphedema: A Pilot Clinical Trial

This is a preliminary study to investigate the feasibility of electronic moxibustion in breast cancer patients with upper limb lymphedema. As current treatment options for lymphedema are unsatisfactory and time consuming, there have been attempts to manage symptoms using integrative treatments. Electronic moxibustion was developed to compensate for the shortcomings of conventional moxibustion and is widely used in clinical practice. However, there have been no studies on using electronic moxibustion in breast cancer-related lymphedema. To investigate the feasibility of electronic moxibustion in treating breast cancer-related lymphedema, this study included subjects who completed primary cancer treatment at least 6 months ago and had more than 10 mm difference in arm circumference of upper limbs. All subjects were assigned to the treatment group. Subjects were treated with 16 sessions (30 minutes/session) of electronic moxibustion for 8 weeks followed by 4 weeks of follow-up. For outcome measures, upper limb circumferences, shoulder range of motion, bioimpedance analysis, and quality of life questionnaire were assessed. All 10 subjects completed the study. The effective index showed 38.21% reduction after treatment ( P = .0098) and 29.35% ( P = .0039) after 4 weeks of follow-up compared to the baseline. The reduction of lymphedema was most prominent at 10 cm above the elbow crease, where the mean reduction of circumference difference was 7.5 mm ( P = .0430) and continued to improve after treatment (mean reduction of 8.3 mm, P = .0156). There was significant improvement in shoulder range of motion only in flexion and internal rotation at week 9. There were 7 adverse events, and most were irrelevant to the treatment. Only 1 participant had a mild burn on the acupuncture point. Here, we demonstrate for the first time that electronic moxibustion treatment is a feasible treatment for breast cancer-related lymphedema. Electronic moxibustion may reduce differences in upper limb circumference and improve shoulder range of motion. A future comparative clinical trial is needed to confirm the clinical efficacy of this treatment.

Acupuncture therapy for breast cancer-related lymphedema: A systematic review and meta-analysis

This study aimed to conduct a comprehensive analysis of clinical studies on acupuncture treatment for breast cancer-related lymphedema (BCRL), so as to explore the efficacy and safety of acupuncture treatment and provide evidence for the clinical decision-making. Public databases, mainly including China Academic Journals Full-text Database, Database of Chinese Sci-Tech Journal, Wanfang, PubMed, Embase and the Cochrane Library, from the establishment of databases to December 2018 were searched for randomized controlled trials (RCT) of acupuncture for BCRL. Clinical RCT on the treatment of BCRL with acupuncture combined with drugs or functional exercise were enrolled for the analysis. Bias risk and quality were assessed by two investigators according to the Cochrane Handbook 5.1.0 standard, and the Revman 5.3 software was used for meta-analysis. A total of 13 studies were enrolled, comprising 747 patients (377 in the treatment group and 370 in the control group). The results of meta-analysis showed that acupuncture intervention could improve the total effective rate for the treatment of BCRL (odds ratio = 4.62; 95% confidence interval 2.61-8.17). Recent studies suggest that acupuncture therapy can alleviate the upper limb swelling and improve the subjective pain and discomfort in patients with BCRL, regardless of the control intervention used. However, the number of high-quality RCT is low. Moreover, most of the studies adopted inconsistent efficacy indicators. Hence, additional blinded, large-sample, randomized, well-controlled studies with objective and uniform efficacy indicators are needed, especially in China, to confirm the findings.

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.

Lymphatic Function in Autoimmune Diseases

Lymphatic vessels are critical for clearing fluid and inflammatory cells from inflamed tissues and also have roles in immune tolerance. Given the functional association of the lymphatics with the immune system, lymphatic dysfunction may contribute to the pathophysiology of rheumatic autoimmune diseases. Here we review the current understanding of the role of lymphatics in the autoimmune diseases rheumatoid arthritis, scleroderma, lupus, and dermatomyositis and consider the possibility that manual therapies such as massage and acupuncture may be useful in improving lymphatic function in autoimmune diseases.

Acupuncture in adults with Chemotherapy-Induced Peripheral Neuropathy: a systematic review

Objective:

to analyze and synthesize knowledge about the effect of acupuncture on chemotherapy-induced peripheral neuropathy symptoms in adults with cancer.

Method:

the method used was a Systematic Review. Potential articles were identified by searching in the PubMed of National Library of Medicine, Cumulative Index to Nursing and Allied Health Literature, Embase, Cochrane Central and Scopus. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy, 607 articles were identified. After removing the duplicates, all titles and abstracts were reviewed, and seven articles were selected for full review. After the full review, five studies were selected for inclusion.

Results:

of the five articles included, four were cohort studies and one was a quasi-experimental study. All articles showed that acupuncture was associated with an improvement in the peripheral neuropathy, but the type of protocol, use of medications, time of treatment, and different outcome measures made it difficult to compare the studies.

Conclusion:

the use of acupuncture appears to be associated with an improvement in the symptoms of chemotherapy-induced peripheral neuropathy and has no side effects. In order to improve the evidence about benefits associated with acupuncture, more experimental studies using both subjective and objective measures are needed.
