“…acupuncture is as effective as hormone therapy for alleviating the general symptoms of menopause in breast cancer patients undergoing hormone therapy“
PLoS One. 2017 Aug 22;12(8):e0180918.
A systematic review by Taiwanese authors has found that acupuncture is as effective as hormone therapy for alleviating the general symptoms of menopause in breast cancer patients undergoing hormone therapy. Their meta-analysis examined data from 13 medium-to-high quality RCTs involving 844 breast cancer patients.
The results indicated that acupuncture significantly ameliorated general menopause symptoms including negative mood, sleep problems, pain, headache and dizziness. While meta analysis suggested that acupuncture did not reduce the severity of hot flushes compared with hormone therapy, the side effects of drug therapy are significant and its safety profile is poor by comparison.
The authors suggest that the mechanism by which acupuncture alleviates menopause symptoms might include regulation of cytokines and the autonomic nervous system.

Chinese Herbal Medicine for Premature Ovarian Failure: A Systematic Review and Meta-Analysis
“The pooled data showed an improvement in symptoms in the Chinese Herbal Medicine group compared to that of the HRT group … FSH levels were significantly lower in patients treated with CHM compared to that of patients treated with HRT … There was no significant difference (P > 0.05) observed in E2 and LH levels when CHM and HRT were compared. Conclusions CHM may relieve symptoms of POF partly through decreasing serum FSH levels, this may provide guidance for future studies. “

Introduction: Premature ovarian failure (POF), loss of normal ovarian function before the age of 40 commonly results in infertility. This systematic review/meta-analysis evaluates the effectiveness of Chinese herbal treatments on POF.
Methods: Systematic searches of six electronic databases were conducted for articles published through June 2013. All randomized controlled trials which compared Chinese herbal medicine (CHM) as solitary treatment versus hormone replacement therapy (HRT) for POF were included. Measurement of treatment effect was done through pooled odds ratio (OR) of effective cases in the two groups, and weighted mean difference (WMD) of hormonal levels (E2, FSH, LH) after treatment.
Results: This meta-analysis includes 10 randomized controlled trials (RCTs) involving 888 patients in comparing CHM with HRT for the treatment of POF. The pooled data showed an improvement in symptoms in the CHM group compared to that of the HRT group (OR = 2.50, 95% CI: 1.49–4.18, P < 0.001). FSH levels were significantly lower in patients treated with CHM compared to that of patients treated with HRT (≥6 M: WMD = -8.34, 95% CI: -11.96, P < 0.001, -4.71; <6 M: WMD = -5.23, 95% CI: -8.68, -1.78, P = 0.003). There was no significant difference (P > 0.05) observed in E2 and LH levels when CHM and HRT were compared.
Conclusions: Chinese Herbal Medicine may relieve symptoms of Premature Ovarian Failure partly through decreasing serum FSH levels, this may provide guidance for future studies.

The Chinese medicine therapies of “acupuncture, CHM and moxibustion show promising results for the treatment of mood and pain symptoms co-occurring with hot flushes”
Climacteric. 2015 Apr;18(2):142-56. doi: 10.3109/13697137.2014.937687. Epub 2014 Oct 18.

AIMS:
To review controlled clinical trials of traditional Chinese medicine (TCM) therapies for hot flushes and at least one other co-occurring symptom among sleep, cognitive function, mood, and pain.
METHODS:
An experienced reference librarian performed an extensive search of PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for randomized, controlled trials reported in English between 2004 and July 2011. Of 1193 abstracts identified, 58 trials examined effectiveness of therapies for hot flushes and at least one additional co-occurring symptom.
RESULTS:
Eleven trials (13 publications) examined TCM therapeutics of acupuncture, Chinese herbal medicine (CHM) or moxibustion. Acupuncture trials (eight) yielded mixed results; five trials significantly reduced hot flushes. Of those five trials, one also showed benefit for sleep and pain and two trials found benefit for mood symptoms. Of three CHM trials, three trials had significant findings: one for hot flushes and mood, one for hot flushes and pain, and one for hot flushes, sleep, mood symptoms and pain. Moxibustion and counseling (one trial) significantly reduced hot flushes, mood symptoms and pain. None of the trials reported any serious adverse events.
CONCLUSIONS:
TCM therapeutics of acupuncture, CHM and moxibustion show promising results for the treatment of mood and pain symptoms co-occurring with hot flushes. Although the controlled clinical trials of TCM therapeutics reviewed here measured multiple symptom outcomes, few report treatment effects in ways that allow clinicians to consider symptom clusters when prescribing therapies. Future studies need to measure and report results for individual symptoms or group like symptoms together into subscales. Controlled clinical trials with larger numbers of participants are essential to allow evaluation of these therapies on hot flushes and multiple co-occurring symptoms.

ETHNOPHARMACOLOGICAL RELEVANCE:
Previous studies had indicated that hormone therapy (HT) may increase the risk of ischemic stroke (IS) in menopausal women. However, little is known about the benefits and risks of use of Chinese herbal medicine (CHM) in conditions related to hormone use. The aim of this study is to explore the risk of IS in menopausal women treated with HT and CHM.
MATERIALS AND METHODS:
A total of 32,441 menopausal women without surgical menopause aged 40-65 years were selected from 2003 to 2010 using the 2-million random samples of the National Health Insurance Research Database in Taiwan. According to the medication usage of HT and CHM, we divided the current and recent users into two groups: an HT use-only group (n = 4989) and an HT/CHM group (n = 9265). Propensity-score matching samples (4079 pairs) were further created to deal with confounding by indication. The adjusted hazard ratios (HR) of IS were estimated by the robust Cox proportional hazards model.
RESULTS:
The incidence rate of IS in the HT/CHM group was significantly lower than in the HT group (4.5 vs. 12.8 per 1000 person-year, p < 0.001). Multivariate analysis results indicated that additional CHM use had a lower risk of IS compared to the HT group (HR = 0.3; 95% confidence interval [CI], 0.21-0.43). Further subgroup analyses and sensitivity analyses had similar findings.
CONCLUSION:
We found that combined use of HT and CHM was associated with a lower risk of IS. Further study is needed to examine possible mechanism underlying this association.

OBJECTIVE:
This meta-analysis aims to evaluate the effects of acupuncture on hot flash frequency and severity, menopause-related symptoms, and quality of life in women in natural menopause.
METHODS:
We systematically searched PubMed/Medline, PsychINFO, Web of Science, Cochrane Central Register of Controlled Trials, and CINAHL using keywords such as acupuncture, hot flash, menopause-related symptoms, and quality of life. Heterogeneity, moderator analysis, publication bias, and risk of bias associated with the included studies were examined.
RESULTS:
Of 104 relevant studies, 12 studies with 869 participants met the inclusion criteria and were included in this study. We found that acupuncture significantly reduced the frequency (g = -0.35; 95% CI, -0.5 to -0.21) and severity (g = -0.44; 95% CI, -0.65 to -0.23) of hot flashes. Acupuncture significantly decreased the psychological, somatic, and urogenital subscale scores on the Menopause Rating Scale (g = -1.56, g = -1.39, and g = -0.82, respectively; P < 0.05). Acupuncture improved the vasomotor subscale score on the Menopause-Specific Quality of Life questionnaire (g= -0.46; 95% CI, -0.9 to -0.02). Long-term effects (up to 3 mo) on hot flash frequency and severity (g = -0.53 and g = -0.55, respectively) were found.
CONCLUSIONS:
This meta-analysis confirms that acupuncture improves hot flash frequency and severity, menopause-related symptoms, and quality of life (in the vasomotor domain) in women experiencing natural menopause.

See the study here
J Clin Oncol. 2015 Nov 1;33(31):3615-20. doi: 10.1200/JCO.2015.60.9412. Epub 2015 Aug 24.
In a study concerned specifically with evaluating placebo effects, the authors nonetheless found that “electro-acupuncture may be more effective than Gabapentin, with fewer adverse effects for managing hot flashes among breast cancer survivors; however, these preliminary findings need to be confirmed in larger randomized controlled trials with long-term follow-up.”

PURPOSE: Hot flashes are a common and debilitating symptom among survivors of breast cancer. This study aimed at evaluating the effects of electroacupuncture (EA) versus gabapentin (GP) for hot flashes among survivors of breast cancer, with a specific focus on the placebo and nocebo effects.
PATIENTS AND METHODS: We conducted a randomized controlled trial involving 120 survivors of breast cancer experiencing bothersome hot flashes twice per day or greater. Participants were randomly assigned to receive 8 weeks of EA or GP once per day with validated placebo controls (sham acupuncture [SA] or placebo pills [PPs]). The primary end point was change in the hot flash composite score (HFCS) between SA and PP at week 8, with secondary end points including group comparisons and additional evaluation at week 24 for durability of treatment effects.
RESULTS: By week 8, SA produced significantly greater reduction in HFCS than did PP (-2.39; 95% CI, -4.60 to -0.17). Among all treatment groups, the mean reduction in HFCS was greatest in the EA group, followed by SA, GP, and PP (-7.4 v -5.9 v -5.2 v -3.4; P = < .001). The pill groups had more treatment-related adverse events than did the acupuncture groups: GP (39.3%), PP (20.0%), EA (16.7%), and SA (3.1%), with P = .005. By week 24, HFCS reduction was greatest in the EA group, followed by SA, PP, and GP (-8.5 v -6.1 v -4.6 v -2.8; P = .002).
CONCLUSION: Acupuncture produced larger placebo and smaller nocebo effects than did pills for the treatment of hot flashes. EA may be more effective than GP, with fewer adverse effects for managing hot flashes among breast cancer survivors; however, these preliminary findings need to be confirmed in larger randomized controlled trials with long-term follow-up.
