Acupuncture in the Oncology Setting: Clinical Trial Update

Acupuncture in oncological pain relief: A systematic review of randomized clinical trials

Abstract Introduction: Cancer pain has a considerable impact on patients’ health and quality of life, and its treatment is essentially based on opioid use. Objective: To report the effectiveness of acupuncture in relieving cancer pain (secondary to the disease or to the corresponding therapy) or in decreasing opioid use compared to other interventions. Methods: A systematic review of randomized clinical trials was conducted following the guidelines of the Cochrane Handbook for Systematic Reviews of Interventions. The trials were selected from the PubMed, Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL) databases. Results: The search strategy resulted in the inclusion of eight trials, of which five compared acupuncture and drug therapy and three compared acupuncture and placebo. Seven trials reported decreased pain and analgesic use. The trials showed clinical heterogeneity, making a meta-analysis unfeasible. Conclusion: The findings herein provided no robust evidence to support the routine use of acupuncture as an adjuvant therapy in the treatment of cancer pain. However, its use is promising since the results showed a trend toward decreased pain and analgesic use, thus justifying further studies in the future.

Breast cancer survivors willingness to participate in an acupuncture clinical trial: a qualitative study

PURPOSE

Acupuncture is a complementary and alternative medicine (CAM) modality that shows promise as a component of supportive breast cancer care. Lack of robust recruitment for clinical trial entry has limited the evidence base for acupuncture as a treatment modality among breast cancer survivors. The objective of this study is to identify key decision-making factors among breast cancer survivors considering entry into an acupuncture clinical trial for treatment of symptoms.

METHODS

Semistructured interviews were conducted among African-American (n=12) and Caucasian (n=13) breast cancer survivors. Verbatim transcripts were made and analyzed by two or more independent coders using NVivo software. Major recurring themes were identified and a theoretical framework developed.

RESULTS

Six themes emerged reflecting key attributes of the decision to enter a clinical trial: (1) symptom appraisal, (2) practical barriers (e.g., distance and travel), (3) beliefs about the interventions (e.g., fear of needles and dislike of medications), (4) comfort with elements of clinical trial design (e.g., randomization, the nature of the control intervention, and blinding), (5) trust, and (6) altruism. African-American and Caucasian women weighed similar attributes but differed in the information sources sought regarding clinical trial entry and in concerns regarding the use of a placebo in a clinical trial.

CONCLUSIONS

Our findings contribute to the development of a theoretical model of decision making for breast cancer survivors considering participation in a CAM clinical trial. Insights regarding the decision making process can inform interventions to support informed decision making and robust recruitment to CAM trials among cancer survivors.
