Acupuncture is a method of producing analgesia or altering the function of a body system by inserting fine, wire-thin needles (about the diameter of a strand of hair) into acupoints along a specific meridian (meridians are channels in the body that transport energy). Electroacupuncture involves the application of a pulsating electrical current to acupuncture needles to stimulate the acupoint via an electrode that is attached to the acupuncture needles. The electrical current substitutes for maneuvering the needles by hand. The P6 acupuncture point is most commonly used for nausea and vomiting. Acupuncture and electroacupuncture have been evaluated for their effects on anxiety, chemotherapy-induced nausea and vomiting, dyspnea, pain, depression, lymphedema, hot flashes, sleep–wake disturbances, peripheral neuropathy, and fatigue in patients with cancer.

Studies addressed potential management of the following symptoms:
The strongest evidence that the study produced showed that acupuncture may be effective for the management of CINV. The study did not show acupuncture to be efficacious in the treatment of other symptoms.
The studies included were of low quality.
Available evidence, which was limited, did not support the claim that acupuncture is effective in alleviating various adverse symptoms in adults with cancer. Additional research is needed to determine the efficacy. The findings of this analysis suggested that patients with uncontrolled CINV may be appropriate candidates for acupuncture referral. For the treatment of other symptoms, the efficacy is undetermined.

PHASE OF CARE: Multiple phases of care
APPLICATIONS: Elder care
The studies included 11 quantitative and one qualitative study. Their findings showed positive effects on sleep in two studies, one of which was a single-arm, nonrandomized study. Positive effects were shown on anxiety in three studies, one of which was single-arm. Four studies showed positive effects on depression, one of which was single-arm. Five studies did not show acupuncture to have any effects. It was noted that acupuncture methodology was inconsistently reported. There also was a lack of data such as standard deviations and change scores.
This review showed mixed results for the effects of acupuncture on sleep, depression, and anxiety. The current evidence has several study design and reporting limitations.
There is no strong evidence to support the use of acupuncture for the treatment of anxiety, depression, or sleep disturbances.

STUDY PURPOSE: To review randomized, controlled trials on the current evidence on the therapeutic effects of acupoints stimulation for patients with cancer with anxiety and depression
TYPE OF STUDY: Systematic review
APPLICATIONS: Palliative care
Overall, the findings really did not support acupoints as a useful approach for managing anxiety and depression. Although it has limited risks, it may be useful in patients who do not tolerate oral medications. Results should be interpreted with caution because of the limitations identified. Still, much needs to be researched in this area. Study heterogeneity and lack of standardization of care and design are some of the major limitations to this meta-analysis. Further studies including controls for environmental as well as study site differences are needed before these results can be interpreted. Generalizability is not possible outside of the current study demographics, which should also be taken into account for future studies.
Acupoints could be a safe intervention used in clinical practice for patients with cancer who experience anxiety and depression. No serious harm was reported, so it could be used as an alternative to medications when patients do not tolerate. Still, much research needs to be conducted in this area.

To determine if acupuncture reduced cancer-related fatigue (CRF) more effectively than did sham acupuncture.
Patients were randomized to an acupuncture or sham control group. Treatments were given once a week over six weeks. In the acupuncture group, a total of 14 needles were inserted at defined points during each session. The needles were stimulated manually and retained for 20 minutes. Sham needles, used in the control group, were blunt-tipped, moved up inside their handles when pressed against the skin, and did not penetrate the skin. In the control group, sham needles were applied in the same number and using the same technique as were the needles in the acupuncture group. Outcome measures were obtained at two weeks and at one week prior to the start of interventions and again at 42 and 49 days after completion.
Patients were undergoing the transition phase after initial treatment.
The study was a double-blind, randomized, sham-controlled trial.
The study showed that acupuncture had no effect on the symptoms of fatigue, anxiety, or depression.
The study did not demonstrate that acupuncture had an effect on fatigue, anxiety, or depression. The study contributes to a growing body of research that shows conflicting results regarding the effectiveness of this intervention for the management of fatigue. It has been shown that symptoms such as fatigue and anxiety tend to decline over time among patients with cancer. It is unclear if the timing in this study affected the results; symptoms may have declined with or without the intervention.

To examine electroacupuncture (EA) compared to sham acupuncture (SA) and a waitlist control (WLC) group to determine effectiveness on fatigue, sleep disturbance, depression, and anxiety in postmenopausal breast cancer survivors who reported joint pain, or arthralgia, related to aromatase inhibitors (anastrazole, letrozole, exemestane)
Acupuncture interventions were administered by two licensed acupuncturists (not physicians). Ten treatments were administered over eight weeks with two treatments during each of the first two weeks followed by one treatment per week for the following six weeks. The EA and SA treatments were administered by the same two acupuncturists. Procedures for the two groups differed in the placement of the acupuncture needles and actual versus sham electrical stimulation using a transcutaneous electrical nerve stimulation (TENS) unit. The same timing and duration of treatments was used for each group.
Three-group randomized controlled trial comparing EA, SA, and WLC.
Four measurement tools were used: the Brief Pain Inventory (BPI); the Brief Fatigue Inventory (BFI); the Pittsburgh Sleep Quality Index (PSQI); and the Hospital Anxiety and Depression Scale (HADS). A priori primary outcome reported pain intensity and interference. A priori secondary outcome reported fatigue, sleep, and psychological distress (anxiety, depression).
Measurements were repeated at weeks 4, 8, and 12. There was significant (p = 0.0095) improvement in the fatigue score after EA, no improvement with SA, and greater reduction in fatigue than the WLC group. There were nonsignificant improvements in sleep in the EA and SA groups compared to the WLC group. There was significant (p = 0.04) improvement in the EA group but the SA group on the HADS anxiety score compared to the WLC group; a nonsignificant improvement continued in the EA group at week 8, whereas week 12 showed a significant (p = 0.006) improvement in the EA and WLC groups. EA and SA group improvements in depression scores were significant (p = 0.015 and p = 0.0088, respectively) compared with the WLC group; EA and SA significantly (p = 0.0031m and p = 0.0056, respectively) improved scores at week 8, and scores did not change at week 12.
EA produced improvements by reducing fatigue, anxiety, and depression scores. SA produced improvements in depression scores only. Acupuncture with electronic stimulation may be an effective treatment for pain and the nonpain symptoms of fatigue, sleep disturbance, and depression associated with AIs. Additional research is encouraged.
Acupuncture with electrical stimulation should be considered a viable treatment option for patients with breast cancer taking AIs who complain of joint pain. Large, randomized, controlled research studies are needed to develop evidence for the efficacy of EA in breast and other cancers. Drug and symptom cluster correlations must be deconstructed.

A randomized, controlled trial of acupuncture self-needling as maintenance therapy for cancer-related fatigue after therapist-delivered acupuncture. Annals of Oncology, 24, 1645–1652.
To determine if maintenance acupuncture is beneficial in sustaining improvements in fatigue after a course of acupuncture.
Patients in a previous six-week acupuncture trial were rerandomized to three groups: maintenance self-acupuncture, therapist-delivered maintenance acupuncture, or a control group receiving usual care. Maintenance therapy lasted for four weeks. Standard acupuncture points were used, and sessions were weekly. Data were collected at the end of four weeks and at 12 weeks after rerandomization.
Patients were undergoing the transition phase of care after active treatment.
The study was a randomized, controlled trial.
Results showed a trend of fatigue improvement in the combined acupuncture groups compared to the control; the trend was not significant. In regard to results reflecting anxiety or depression, the study showed no differences between groups. Patients' logs indicated that patients performed self-needling as planned.
Findings suggested that it is feasible for patients to maintain acupuncture treatment through self-needling. Compared to symptom improvement in patients in the control group, symptom improvement in patients undergoing maintenance acupuncture through self-needling or through delivery by a therapist was not significant.
The study showed that patients can be taught to deliver their own acupuncture treatments effectively by self-needling. The study did not demonstrate that ongoing acupuncture, or maintenance acupuncture, had any effect on fatigue, anxiety, or depression.

To investigate the effects of acupuncture on nausea, vomiting, pain, sleep quality, and anxiety in patients who were hospitalized or undergoing chemotherapy
Acupuncture was given for three days. On the day of hospitalization and after three days, study assessments were completed. Chemotherapy-induced nausea and vomiting (CINV) was not measured in patients receiving chemotherapy for the first time.
The sign test was used to show the pre- and post-treatment significance of differences, and these were shown for all symptoms (p < 0.001). However, the pretreatment score for insomnia was equal to one before and after treatment, and a larger proportion of patients did not improve (57.8%) than improved (42.2%) in terms of sleep quality. In other symptoms, the percentage that improved was similar to the percentage that did not improve. The intervention group appeared to have the greatest number of patients whose nausea improved.
Acupuncture may be a useful adjunctive therapy for the management of pain, CINV, anxiety, and insomnia in hospitalized patients receiving chemotherapy. The design of this study limits the strength of its findings.
Acupuncture is a complementary therapy that may be beneficial as an adjunct treatment for symptom management in patients with cancer. This individual study has multiple limitations, and additional evidence is needed to evaluate the effectiveness of acupuncture.
