Acupuncture (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Laboratory / Animal / Preclinical Studies


Another cutaneous cancer pain model has been established by injecting B16-BL6 melanoma cells into the plantar region of one hind paw of C57BL/6 mice. A single EA treatment showed significant analgesia on day 8 but not on day 20. EA treatments once every other day starting on day 8 showed analgesia at day 20, but EA starting on day 16 did not. The results indicate that EA exerts antihyperalgesic effects on early stage but not on late stage cutaneous cancer pain.[9] These animal studies support the clinical use of EA in the treatment of cancer pain.

The findings of these studies suggest that acupuncture may be effective in treating cancer-related symptoms and cancer treatment–related disorders and that acupuncture may be able to activate immune functions [1,2,3] and regulate the autonomic nervous system.[4,5] Only one study reported a decrease in tumor volume in animals treated with acupuncture compared with control animals; however, the scientific value of this report is limited because of insufficient information about the research methodology.[2]
