History

The generally accepted history of acupuncture/moxibustion (known as zhen jiu) is part of traditional Chinese medicine (TCM), an indigenous, coherent system of medicine that has been practiced in China for thousands of years. The history of acupuncture/moxibustion in China can be traced back archeologically at least 4,000 years, when bian (stone needles) were in use. During the long history of recorded practice, acupuncture has been applied to many disorders. The earliest written medical text, the ancient classic Huang Di Nei Jing (Yellow Emperor's Inner Classic, second century BC), records nine types of needles and their therapeutic functions.

The dissemination of acupuncture and TCM to other regions dates back centuries; first to Korea and Japan and then to other Asian countries.[1] The use of acupuncture in Europe was documented in the middle of the 16th century.[2] The relatively brief history of acupuncture in the United States can be traced back about 200 years, when Dr. Franklin Bache published a report in the North American Medical and Surgical Journal on his use of acupuncture to treat lower back pain.[3] However, until the 1970s, when U.S.–Chinese diplomatic ties were resumed, the practice of acupuncture in this country was mainly limited to Chinatowns.[4]

For centuries, Chinese acupuncturists treated cancer symptomatically. Ancient literature and acupuncture textbooks classify cancer as a Zhi syndrome or blood stasis condition and document acupuncture treatment principles and methods.[5-7] Since the development of modern conventional medicine, acupuncture has primarily been used clinically as an adjunct to conventional cancer treatment.

Laboratory/Animal/Preclinical Studies

At least seven animal studies investigating the effects of acupuncture in cancer or cancer-related conditions have been reported in the scientific literature.[1-5] Two of the studies were conducted in China, one of which was published in Chinese with an English abstract. One study was conducted in Japan, one in Sweden, and one in the United States. Four of the studies were ex vivo laboratory investigations using blood or tissue samples;[1-3,5] the remaining study was an animal behavioral study testing the effect of acupuncture on chemotherapy-induced nausea and vomiting. [4]

The four ex vivo studies suggested that acupuncture is useful in anticancer therapy either by actively stimulating immune activity or by preventing chemotherapy suppression of immune activity.[1-3,5]

In a study involving normal rats, electroacupuncture (EA) (1 Hz, 5–20 V, 1-millisecond pulse width, 2 hours) applied at the point Zu-Sanli (S36) for 2 hours daily on 3 consecutive days enhanced the cytotoxicity of splenic natural killer (NK) cells compared with a stimulation of a nonacupuncture control point in the abdominal muscle.[3]

Another study found that NK cell activity and T-lymphocyte transformation rate were increased in a mouse model of transplanted mammary cancer compared with a control (P < .05) after eight sessions of acupuncture and moxibustion.[2]

A study involving tumor-bearing mice (sarcoma S180) using moxibustion to warm the acupuncture point Guanyuan (CV4) once a day for 10 days found significantly increased production of erythrocytes, compared with a nontreatment control.[1]

The fourth ex vivo study used a rat model to investigate the effect of EA on nerve growth factor (NGF), which is associated with polycystic ovary syndrome (PCOS). Women with PCOS have an increased risk of endometrial cancer and other diseases. Repeated EA treatments (12 treatments administered over 30 days) in PCO rats significantly lowered the concentrations of NGF in the ovaries, compared with untreated PCO rats.[5]

A study of cyclophosphamide-induced emesis in a ferret behavioral model used acupuncture as an adjunct therapy in treating the emetic side effects of chemotherapy. EA at 100 Hz, 1.5 V, for 10 minutes in combination with subeffective doses of antiemetics such as ondansetron (0.04 mg/kg), droperidol (0.25 mg/kg), and metoclopramide (2.24 mg/kg) significantly reduced the total number of emetic episodes by 52%, 36%, and 73%, respectively (P < .01), in this ferret model.[4]

A rat model has been established by injecting AT-3.1 prostate cancer cells into the tibia of the adult male Copenhagen rat, which closely mimics prostate cancer-induced bone cancer pain.[6] The cancer-caused pain was treated with 10 Hz EA for 30 minutes a day at acupuncture point gallbladder 30 (GB30) from days 14 to 18 after cancer-cell injection. For sham control, EA needles were inserted into GB30 without stimulation. Thermal hyperalgesia, a decrease in paw withdrawal latency to a noxious thermal stimulus, and mechanical hyperalgesia, a decrease in paw withdrawal pressure threshold, were measured at baseline and 20 minutes after EA. EA significantly attenuated the hyperalgesia compared with sham control. Moreover, the EA inhibited up-regulation of preprodynorphin mRNA and dynorphin as well as interleukin-1beta (IL-1beta) and its mRNA compared with sham control. Intrathecal injection of antiserum against dynorphin A (1–17) and IL-1 receptor antagonist significantly inhibited the cancer-induced hyperalgesia. These data suggests that EA alleviates bone cancer pain at least in part by suppressing spinal dynorphin and IL-1beta expression.[7,8]

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 [1-3] 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]
