Evaluation of Group Acupuncture for Cancer-Related Symptoms: A Retrospective Analysis.

BACKGROUND

Acupuncture is being used for treatment of cancer-related symptoms in numerous settings, yet empirical evidence supporting the effects of acupuncture in this setting is lacking. Group acupuncture is an economical way to provide acupuncture to patients at a reduced cost.

OBJECTIVE

In this retrospective study we sought to evaluate the effects of group acupuncture on specific cancer-related symptoms in persons receiving outpatient cancer treatment.

METHODS

Patients were receiving group acupuncture treatments through an integrative oncology program in a large community oncology practice in west central Florida. A short patient-completed assessment of seven basic cancer-related symptoms using a 0-10 numeric rating scale was completed at each acupuncture treatment. Basic demographic information, including age, gender, race/ethnicity, and cancer type was obtained from the medical record. Paired sample t-tests were used to evaluate differences in symptoms before the first treatment and at the fourth treatment.

RESULTS

Fifty patients completed at least four weekly acupuncture treatments in 2014. Forty-three of them completed symptom assessments and were included in this analysis. The mean age of participants was 66.4 years. The majority of patients were white, non-Hispanic, and female. No significant improvement in symptoms were identified at the third treatment. At the time of the fourth group acupuncture, participants reported significantly less pain/numbness and problems with digestion.

DISCUSSION

The results of this study provide evidence to support the efficacy of group acupuncture for pain, neuropathy, and digestive problems in persons with cancer. A minimum of four weekly treatments may be necessary before improvements are noted. Limitations include a retrospective design, incomplete symptom evaluation, and possible response bias. Future studies of group acupuncture for cancer-related symptoms should utilize a prospective, controlled design, use validated measures to thoroughly evaluate targeted symptoms, and include a more racially and ethnically diverse sample.
