Acupuncture as a Therapeutic Treatment for Cancer Pain

ACUPUNCTURE FOR CANCER PAIN: THE CLINICAL EVIDENCE

A Comparative Literature Review in 2017 found a potentially positive effect of acupuncture in treating cancer pain.3 The review included two systematic reviews, the older of which was unable to draw firm conclusions due to small sample sizes and clinical differences in the patients being treated. The more recent review included 36 trials and over 2200 randomised patients. They found a moderate effect size of acupuncture on cancer-related pain, and concluded that “acupuncture is effective in relieving cancer-related pain, particularly malignancy-related and surgery-induced pain.”4

Although this review did not report on risks arising from treatment with acupuncture, elsewhere studies have indicated that acupuncture is a feasible and safe treatment56 and may successfully be used to treat cancer patients for symptom management due to the low risks associated with its use.7

HOW ACUPUNCTURE TREATS CANCER PAIN: BIOLOGICAL MECHANISMS

Acupuncture’s mechanisms for treating cancer pain are thought to be similar to those for treating other painful conditions, whether the pain is categorised as acute or chronic.

These mechanisms have been researched extensively for over 60 years, and while there is still much left to learn about acupuncture mechanisms and the human body in general, the neural pathways from acupuncture point stimulation to the spinal cord and then to the deactivation of the pain centres in the brain have been mapped.89Acupuncture has been demonstrated to activate a number of the body’s own opioids as well as improve the brain’s sensitivity to opioids.10 A number of other biochemicals involved in pain reduction have been found to be released and regulated by acupuncture stimulation, including ATP, adenosine, GABA and substance P.11 Acupuncture has also been demonstrated to reduce activity in the parts of the brain associated with the perception of pain and increase activity in brain areas associated with improved self-regulation.12
