Background. Fatigue is a distressing and pervasive problem for people with cancer. In recent years, acupuncture has gained increasing attention among researchers as an alternative management strategy for cancer-related fatigue (CRF). This review aimed to evaluate the effectiveness of acupuncture for CRF. Methods. Five databases (Medline, CINAHL, Scopus, the Cochrane Library, and CAJ Full-text Database) were searched up to May 2013. Randomized controlled trials (RCTs) of acupuncture for the treatment of CRF were considered for inclusion. Results. Seven RCTs were included for meta-analysis, involving a total of 689 subjects. Three studies compared acupuncture with sham acupuncture for CRF with follow-up at 10 weeks; the standardized mean difference (SMD) for general CRF change values was -0.82 (95% confidence interval [CI] = -1.90 to 0.26). When acupuncture plus education intervention was compared with usual care, there was a statistically significant difference for the change score of general CRF (SMD = -2.12; 95% CI = -3.21 to -1.03). The SMD for general CRF change scores between acupuncture with no treatment or wait-list control was -1.46 (95% CI = -3.56 to 0.63). Finally, the SMD for general CRF change scores between acupuncture with acupressure or self-acupuncture was -1.12 (95% CI = -3.03 to 0.78). Three trials reported data for general quality of life and functioning status, reporting enough data for statistical pooling but showing no statistically significant difference (Z score = 1.15, P = .25, SMD = 0.99, 95% CI = -0.70 to 2.68 and Z score = 1.13, P = .26, SMD = 1.38, 95% CI = -1.02 to 3.79, respectively). The I (2) statistics of all statistically pooled data were higher than 50%, indicating heterogeneity between the trials. Conclusions. There were 4 sets of comparison for the effectiveness of acupuncture for CRF; statistical pooling of the reduction in CRF from baseline to follow-up showed in favor of acupuncture. However, 3 sets of comparison for the pooled estimates of effect sizes had no statistical significance. Although one set of comparison (acupuncture plus education interventions vs usual care) had statistically significant differences, it is unclear whether this pooled positive outcome is attributable to the effects of acupuncture or to the education intervention. In addition, the duration of follow-up in these included trials was up to 10 weeks, and some RCTs had methodological flaws. Further rigorously designed RCTs adhering to acceptable standards of trial methodology are required to determine the effectiveness of acupuncture and its long-term effects on CRF.
Fatigue, experienced by patients during and following cancer treatment, is a significant clinical problem. It is a prevalent and distressing symptom yet pharmacological interventions are used little and confer limited benefit for patients. However, many cancer patients use some form of complementary and alternative medicine (CAM), and some evidence suggests it may relieve fatigue. A systematic review was conducted to appraise the effectiveness of CAM interventions in ameliorating cancer-related fatigue. Systematic searches of biomedical, nursing, and specialist CAM databases were conducted, including Medline, Embase, and AMED. Included papers described interventions classified as CAM by the National Centre of Complementary and Alternative Medicine and evaluated through randomized controlled trial (RCT) or quasi-experimental design. Twenty studies were eligible for the review, of which 15 were RCTs. Forms of CAM interventions examined included acupuncture, massage, yoga, and relaxation training. The review identified some limited evidence suggesting hypnosis and ginseng may prevent rises in cancer-related fatigue in people undergoing treatment for cancer and acupuncture and that biofield healing may reduce cancer-related fatigue following cancer treatments. Evidence to date suggests that multivitamins are ineffective at reducing cancer-related fatigue. However, trials incorporated within the review varied greatly in quality; most were methodologically weak and at high risk of bias. Consequently, there is currently insufficient evidence to conclude with certainty the effectiveness or otherwise of CAM in reducing cancer-related fatigue. The design and methods employed in future trials of CAM should be more rigorous; increasing the strength of evidence should be a priority.
BACKGROUND: Faced with highly prevalent and recalcitrant cancer-related fatigue (CRF), together with the absence of any official guidelines on management, numerous groups have been striving to seek and test alternative therapies including acupuncture and moxibustion. However, different patients have various feedbacks, and the many clinical trials have given rise to varied conclusions. In terms of the therapeutic effect of acupuncture and moxibustion, there exist vast inconsistencies. OBJECTIVE: The aim of the study was to evaluate the auxiliary effectiveness of acupuncture and moxibustion in the treatment of CRF, and to provide more reliable evidence to guide clinical practice. METHODS: Randomized controlled trials (RCTs) published before December 2012 were all aggregated, focusing on evaluation of acupuncture or moxibustion for CRF. The quality of the included studies was assessed basing on Cochrane handbook 5.1.0, and the available data were analyzed with RevMan software (version 5.2.0). Descriptive techniques were performed when no available data could be used. RESULTS: A total of 7 studies involving 804 participants were eligible. With real acupuncture versus sham acupuncture, subjects receiving true acupuncture benefited more in the reduction of fatigue. With real acupuncture versus acupressure or sham acupressure, fatigue level appeared 36% improved in the acupuncture group, but 19% in the acupressure group and only 0.6% with sham acupressure. When real acupuncture plus enhanced routine care was compared with enhanced routine care, the combination group improved mean scores for general fatigue, together with physical and mental fatigue. With real acupuncture versus sham acupuncture or wait list controls, the real acupuncture group displayed significant advantages over the wait list controls at 2 weeks for fatigue improvement and better well-being effects at 6 weeks. When moxibustion plus routine care was compared with routine care alone, the meta-analyses demonstrated the combination had a relatively significant benefit in improving severe fatigue and QLQ-C30. CONCLUSION: Up to the search date, there exist few high quality RCTs to evaluate the effect of acupuncture and moxibustion, especially moxibustion in English. Yet acupuncture and moxibustion still appeared to be efficacious auxiliary therapeutic methods for CRF, in spite of several inherent defects of the included studies. Much more high-quality studies are urgently needed.
PURPOSE: Managing cancer-related fatigue (CRF) is an important element of the palliative care of cancer patients. The aim of this systematic review was to critically evaluate the effectiveness of acupuncture (AT) or electroacupuncture (EA) for CRF.
METHODS: Fourteen databases were searched from their respective inception to November 2012. Randomized clinical trials (RCTs) of AT or EA for the treatment of CRF were considered for inclusion. The risk of bias/methodological quality was assessed using the method suggested by the Cochrane Collaboration.
RESULTS: Seven RCTs met the eligibility criteria. Most were small pilot studies with serious methodological flaws. Four of the RCTs showed effectiveness of AT or AT in addition to usual care (UC) over sham AT, UC, enhanced UC, or no intervention for alleviating CRF. Three RCTs showed no effect of AT/EA over sham treatment.
CONCLUSION: Overall, the quantity and quality of RCTs included in the analysis were too low to draw meaningful conclusions. Even in the positive trials, it remained unclear whether the observed outcome was due to specific effects of AT/EA or nonspecific effects of care. Further research is required to investigate whether AT/EA demonstrates specific effects on CRF.
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.
