Acupuncture appears to be a potentially effective treatment for reducing hot flashes in women diagnosed with breast cancer.
In this systematic review, seven extensive databases including internationally recognized sources like PubMed, Web of Science, and Embase were searched without any language restrictions to identify relevant randomized controlled trials (RCTs) investigating the impacts of acupuncture on hot flashes in women with breast cancer. The timeframe of these searches spanned from the inception of each database to June 2015.
The results of the 12 identified RCTs suggested an overall potential therapeutic effect of acupuncture on hot flashes in women with breast cancer. Notably, out of these, three studies highlighted a significant difference compared with control groups while one showed encouraging trends. Six studies suggested no notable difference between acupuncture and control treatments. A further two trials revealed negative results when compared to hormone therapy. A meta-analysis of the results also suggested differences in the number of hot flashes post-treatment and during subsequent follow-ups compared with control groups. In three trials, Kupperman index scores were reported, indicating a significant difference between acupuncture and controls after treatment and during follow-up. However, due to the overall relatively small number and inconsistent quality of the reviewed studies, these results should be interpreted with caution.

Systematic Review Breast Cancer Lymphoedema
The methodology of this study began with a detailed survey of public databases, including China Academic Journals Full-text Database, Database of Chinese Sci-Tech Journal, Wanfang, PubMed, Embase and the Cochrane Library, and focused on looking for randomized controlled trials related to the use of acupuncture for the treatment of breast cancer-related lymphedema. Clinical trials on the treatment of this condition, where acupuncture was used in conjunction with drugs or functional exercise, were singled out for inclusion in the study. The assessment of any potential risk of bias and quality was performed by two investigators using Cochrane Handbook standard, accompanied by meta-analysis with the help of Revman software.
As for the discussion of the results, the study comprised 13 different studies, enrolling a total of 747 patients. Analysis of these enrolled studies revealed that the use of acupuncture intervention showed an increase in success rate in treating breast cancer-related lymphedema. This was evidenced by an observed improvement in the subjective pain, discomfort, and upper limb swelling in patients who received acupuncture therapy, irrespective of the control intervention used. However, it was mentioned that the majority of the studies used in the assessment contained inconsistent efficacy indicators.

Systematic Review Breast Cancer
The methodology involved a broad electronic search through six databases for research papers published till November 2017. Only randomized controlled trials focused on the use of acupuncture for breast cancer-related lymphedema were included in the process. Ultimately, six trials, involving a cumulative total of 318 patients, were identified for evaluation. The main outcomes looked at were the pre/post-treatment differences in the diameter of the elbow joint, reductions in upper limb lymphedema and effectiveness index based on arm measurement data in patients with breast cancer.
The analysis of results revealed an overall positive effect of acupuncture intervention on the parameters examined. Two of the studies observed a significant reduction in elbow joint diameter and upper limb lymphedema in the acupuncture groups. Another two studies noted a marked difference in the effectiveness index based on arm measurements between the acupuncture and control groups, favoring the former. The fifth study used bioelectrical impedance spectroscopy and reported a significant reduction in lymphedema. The sixth study, however, did not report any significant difference in bioimpedance between the groups. Overall the results suggest that acupuncture could be an effective method for managing limb oedema in patients post breast cancer treatment.

Meta-Analysis Breast Cancer Cancer Fatigue
In the methodology, seven different medical databases were systematically reviewed for randomized controlled trials concerning the effects of acupuncture on cancer-related fatigue up until November 2016. Two independent reviewers assessed for bias and extracted correlated data with the use of Review Manager 5. Ten trials met the eligibility criteria for the meta-analysis, which incorporated a total of 1327 patients; 733 received acupuncture and 594 served as control.
The results showed that acupuncture markedly mitigated fatigue in cancer patients irrespective of whether they were simultaneously undergoing anti-cancer treatment, with particularly substantial effects among those with breast cancer. The duration and frequency of acupuncture sessions varied, but all schedules produced meaningful effects. While a majority of the trials reported no negative events, one highlighted manageable incidents such as spot bleeding and bruising. Overall, acupuncture was found to be a successful method for managing cancer-related fatigue.
