BACKGROUND: Forty per cent of individuals with early or intermediate stage cancer and 90% with advanced cancer have moderate to severe pain and up to 70% of patients with cancer pain do not receive adequate pain relief. It has been claimed that acupuncture has a role in management of cancer pain and guidelines exist for treatment of cancer pain with acupuncture. This is an updated version of a Cochrane Review published in Issue 1, 2011, on acupuncture for cancer pain in adults. OBJECTIVES: To evaluate efficacy of acupuncture for relief of cancer-related pain in adults. SEARCH METHODS: For this update CENTRAL, MEDLINE, EMBASE, PsycINFO, AMED, and SPORTDiscus were searched up to July 2015 including non-English language papers. SELECTION CRITERIA: Randomised controlled trials (RCTs) that evaluated any type of invasive acupuncture for pain directly related to cancer in adults aged 18 years or over. DATA COLLECTION AND ANALYSIS: We planned to pool data to provide an overall measure of effect and to calculate the number needed to treat to benefit, but this was not possible due to heterogeneity. Two review authors (CP, OT) independently extracted data adding it to data extraction sheets. Data sheets were compared and discussed with a third review author (MJ) who acted as arbiter. Data analysis was conducted by CP, OT and MJ. MAIN RESULTS: We included five RCTs (285 participants). Three studies were included in the original review and two more in the update. The authors of the included studies reported benefits of acupuncture in managing pancreatic cancer pain; no difference between real and sham electroacupuncture for pain associated with ovarian cancer; benefits of acupuncture over conventional medication for late stage unspecified cancer; benefits for auricular (ear) acupuncture over placebo for chronic neuropathic pain related to cancer; and no differences between conventional analgesia and acupuncture within the first 10 days of treatment for stomach carcinoma. All studies had a high risk of bias from inadequate sample size and a low risk of bias associated with random sequence generation. Only three studies had low risk of bias associated with incomplete outcome data, while two studies had low risk of bias associated with allocation concealment and one study had low risk of bias associated with inadequate blinding. The heterogeneity of methodologies, cancer populations and techniques used in the included studies precluded pooling of data and therefore meta-analysis was not carried out. A subgroup analysis on acupuncture for cancer-induced bone pain was not conducted because none of the studies made any reference to bone pain. Studies either reported that there were no adverse events as a result of treatment, or did not report adverse events at all. AUTHORS' CONCLUSIONS: There is insufficient evidence to judge whether acupuncture is effective in treating cancer pain in adults.

OBJECTIVE: To critically evaluate the currently available randomized clinical trials regarding the effectiveness of acupuncture in palliative care for cancer patients, hence, to provide sufficient evidences for the widespread use of acupuncture in cancer treatment. METHODS: Two independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of acupuncture in palliative care for cancer patients. Seven databases were searched from their respective inception to December 2010. All eligible trials identified were evaluated by two independent reviewers using the Jadad scale, and data from the articles were validated and extracted. RESULTS: In total, 33 RCTs met the inclusion criteria. The effects of acupuncture on different cancer-related aspects were shown, including chemotherapy or radiotherapy-induced side effects (13/33, 39.4%), cancer pain (6/33, 18.2%), post-operative urinary retention (4/33, 12.1%), quality of life (2/33, 6.1%), vasomotor syndrome (2/33, 6.1%), post-operative gastrointestinal dysfunction (2/33, 6.1%), prevention of prolonged postoperative ileus (2/33, 6.1%), joint symptoms (1/33, 3.0%), and immunomodulation (1/33, 3.0%). CONCLUSIONS: The result of our systematic review suggested that the effectiveness of acupuncture in palliative care for cancer patients is promising, especially in reducing chemotherapy or radiotherapyinduced side effects and cancer pain. Acupuncture may be an appropriate adjunctive treatment for palliative care.

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.

PURPOSE: Among cancer patients, cancer-related fatigue (CRF) is one of the most common symptoms and adversely affects physical ability and quality of life even several years after treatment. This study aims to evaluate the current evidence for moxibustion in patients with CRF. METHODS: Eighteen databases were searched from their inception to April 2013. All randomized controlled trials (RCTs) of moxibustion for treating CRF without language restriction were considered for inclusion. The risk of bias and reporting quality of each study were assessed using the Cochrane risk of bias tool, Consolidated Standards of Reporting Trials (CONSORT), and Revised Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA). Risk ratio (RR) or mean difference (MD) was used to measure the treatment effect with 95 % confidence intervals (CIs) in a random effects model. RESULTS: Four RCTs with a total of 374 subjects were included for the review. These four studies compared moxibustion plus routine care with routine care alone. Most studies were determined to have a moderate to high risk of bias with low reporting quality. An indirect moxa stick was used in two studies, an indirect ginger cake-separated moxa was used in one study, and in one remaining study, both moxibustion methods were used. Meta-analysis showed the favorable effects of moxibustion on the response rate (RR, 1.73; 95 % CI, 1.29 to 2.32; p=.0003; heterogeneity, I (2)=15 %, p=.32). Burning with a mild blister after moxibustion was reported in one study. CONCLUSIONS: Because of a high risk of bias and low reporting quality of the studies included in this review, it is difficult to draw the conclusion that moxibustion is an effective and safe treatment for patients with CRF. Further rigorous research will be necessary to evaluate whether moxibustion has beneficial effects on CRF. TRIAL REGISTRATION: PROSPERO. Unique identifier: CRD42013004501.

Background. Pharmacopuncture, injection to acupoints with pharmacological medication or herbal medicine, is a new acupuncture therapy widely available in Korea and China for cancer-related symptoms. However, the evidence is yet to be clear. Objective. To determine pharmacopuncture's effectiveness on cancer-related symptoms. Methods. Eleven databases were searched for randomized controlled trials of pharmacopuncture in cancer patients. The Cochrane risk of bias (ROB) assessment tool was used for quality assessment. Results. Twenty-two studies involving 2,459 patients were included. Five trials of chemotherapy-induced nausea and vomiting (CINV) underwent meta-analysis. Pharmacopuncture significantly relieved severity of CINV compared with control group (3 trials, risk ratio (RR) 1.28, 95% confidence interval (CI) = 1.14-1.44). The frequency of CINV was also significantly reduced with pharmacopuncture (2 trials, RR 2.47, 95% CI = 2.12-2.89). Seventeen trials studied various symptoms, and in most studies, pharmacopuncture significantly relieved pain, ileus, hiccup, fever, and gastrointestinal symptoms and improved quality of life in various cancer patients. ROB was generally high. Conclusion. It may be suggested with caution that pharmacopuncture may help various symptom relief in cancer patients, but it is hard to draw a firm conclusion due to clinical heterogeneity and high ROB of the included studies, hence warranting further investigation. © 2014 Soyeon Cheon et al.

PURPOSE: Acupuncture has been suggested as therapy for hot flashes in women with breast cancer and men with prostate cancer. In this systematic review, we sought to evaluate the long-term effects on vasomotor symptoms after the end of a defined treatment period of acupuncture in women with breast cancer and men with prostate cancer. METHODS: A literature search revealed 222 articles within the field. With defined exclusion criteria, we identified 17 studies. We also used the Jadad quality score and identified seven studies with a score of at least 3. RESULTS: Six of seven identified studies qualified for inclusion in an analysis that measured frequency of hot flashes weighted in relation to number of patients (n=172). The average reduction from baseline to end of acupuncture (ranging between 5 and 12 weeks of treatment) showed 43.2 % reduction of hot flashes. At the last follow-up (mean 5.8 months, range 3-9 months) after the end of therapy, the weighted reduction from baseline was sustained at 45.6 % in the 153 of 172 patients (89 %) who were followed up. CONCLUSIONS: Data from six prospective analyzed studies indicate at least 3-month effects after the end of acupuncture treatment for flashes in women with breast cancer and men with prostate cancer. However, larger randomized trials with long-term follow-up will be needed to confirm these preliminary findings.

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: Lung cancer is the leading cause of death in cancer patients. Clinical studies showed that a variety of acupoint stimulations have been extensively used for lung cancer patients, including needle insertion, injection with herbal extraction, plaster application, and moxibustion. However, the role of acupoint stimulation in lung cancer treatment was not fully reviewed. METHODS: In the present study, we conducted a systematic review and meta-analysis on the role of acupoint stimulation in lung cancer treatment by electronic and manual searching in seven databases, including Ovid (Ovid MEDLINE, AMED, CAB Abstracts, EMBASE), EBSCOhost research databases (Academic Search premier, MEDLINE, CIHAHL Plus), PreQuest (British Nursing Index, ProQuest Medical Library, ProQuest Dissertations & Theses A&I, PsycINFO), and ISI web of knowledge (Web of Science, BIOSIS Citation Index, Biological Abstracts, Chinese Science Citation Database), CNKI, Wanfang Data, and CQVIP. RESULTS: Our study showed that acupoint stimulation has strong immunomodulatory effect for lung cancer patients as demonstrated by the significant increase of IL-2, T cell subtypes (CD3+ and CD4+, but not CD8+ cells), and natural killer cells. Further analysis revealed that acupoint stimulation remarkably alleviates the conventional therapy-induced bone marrow suppression (hemoglobin, platelet, and WBC reduction) in lung cancer patients, as well as decreases nausea and vomiting. The pooled studies also showed that acupoint stimulation can improve Karnofsky performance status, immediate tumor response, quality of life (EORCT-QLQ-C30), and pain control of cancer patients. CONCLUSIONS: Acupoint stimulation is found to be effective in lung cancer treatment, further confirmatory evaluation via large scale randomized trials is warranted.

BACKGROUND: Cancer-related pain is complex and multi-dimensional but the mainstay of cancer pain management has predominantly used a biomedical approach. There is a need for non-pharmacological and innovative approaches. Transcutaneous Electric Nerve Stimulation (TENS) may have a role in pain management but the effectiveness of TENS is currently unknown. This is an update of the original review published in Issue 3, 2008. OBJECTIVES: The aim of this systematic review was to determine the effectiveness of TENS for cancer-related pain in adults. SEARCH METHODS: The initial review searched The Cochrane Library, MEDLINE, EMBASE, CINAHL, PsychINFO, AMED and PEDRO databases in April 2008. We performed an updated search of CENTRAL, MEDLINE, EMBASE, CINAHL and PEDRO databases in November 2011. SELECTION CRITERIA: We included only randomised controlled trials (RCTS) investigating the use of TENS for the management of cancer-related pain in adults. DATA COLLECTION AND ANALYSIS: The search strategy identified a further two studies for possible inclusion. One of the review authors screened each abstract using a study eligibility tool. Where eligibility could not be determined, a second author assessed the full paper. One author used a standardised data extraction sheet to collect information on the studies and independently assess the quality of the studies using the validated five-point Oxford Quality Scale. The small sample sizes and differences in patient study populations of the three included studies (two from the original review and a third included in this update) prevented meta-analysis. For the original review the search strategy identified 37 possible published studies; we divided these between two pairs of review authors who decided on study selection; all four review authors discussed and agreed final scores. MAIN RESULTS: Only one additional RCT met the eligibility criteria (24 participants) for this updated review. Although this was a feasibility study, not designed to investigate intervention effect, it suggested that TENS may improve bone pain on movement in a cancer population. The initial review identified two RCTs (64 participants) therefore this review now includes a total of three RCTs (88 participants). These studies were heterogenous with respect to study population, sample size, study design, methodological quality, mode of TENS, treatment duration, method of administration and outcome measures used. In one RCT, there were no significant differences between TENS and placebo in women with chronic pain secondary to breast cancer treatment. In the other RCT, there were no significant differences between acupuncture-type TENS and sham in palliative care patients; this study was underpowered. AUTHORS' CONCLUSIONS: Despite the one additional RCT, the results of this updated systematic review remain inconclusive due to a lack of suitable RCTs. Large multi-centre RCTs are required to assess the value of TENS in the management of cancer-related pain in adults.

PURPOSE: Controlling cancer-related pain is an important component in the palliative care of cancer patients. The objective of this review was to assess the effectiveness of acupuncture for treating cancer pain. METHODS: Fourteen databases were searched from their inception through April 2011. Randomised clinical trials (RCTs) were included if acupuncture was used as the sole treatment or as a part of a combination therapy for cancer pain. Studies were included if they were controlled with a placebo or controlled against a drug-therapy or no-treatment group. The Cochrane criteria were used to assess the risk of bias. RESULTS: A total of 15 RCTs met our inclusion criteria. All of the included RCTs were associated with a high risk of bias. The majority of acupuncture treatments or combination therapies with analgesics exhibited favourable effects compared with conventional treatments in individual studies. However, a meta-analysis suggested that acupuncture did not generate a better effect than drug therapy (n = 886; risk ratio (RR), 1.12; 95% CI 0.98 to 1.28; P = 0.09). The comparison between acupuncture plus drug therapy and drug therapy alone demonstrated a significant difference in favour of the combination therapy (n = 437; RR, 1.36; 95% CI 1.13 to 1.64; P = 0.003). The results of this systematic review provide no strong evidence for the effectiveness of acupuncture in the management of cancer pain. CONCLUSION: The total number of RCTs included in the analysis and their methodological quality were too low to draw firm conclusions. Future rigorous RCTs will be necessary to assess the clinical efficacy of acupuncture in this area.
