Q: Are there studies on effectiveness of treating breast cancerpatients with acupuncture or any in the works? What symptoms of breast cancer and treatment could it help alleviate?
A: Yes, there have been several studies on the effect of acupuncture in helping breast cancer patients. The conditions that acupuncture was shown to help are chemotherapy-induced nausea, vomiting, tamoxifen-induced hot flashes, and aromatase inhibitor-induced joint pain and stiffness. A number of clinical trials have shown that acupuncture helped reduce chemotherapy-induced nausea and vomiting. So far, there have been three randomized, controlled clinical trials showing that acupuncture significantly alleviates tamoxifen-induced hot flashes in breast cancer patients with minimal side effects. We recently finished a multi-center randomized, controlled trial assessing the effect of acupuncture in reducing aromatase inhibitor induced musculoskeletal symptoms. We are analyzing the data and will present the results soon.
Q: When should a patient expect relief and how long should it last?
A: It depends on the condition the patient is being treated for and the patient's state of health and stage of disease. Some conditions, such as chemotherapy-induced nausea and vomiting may only require one or two treatments, whereas chronic conditions such as chemotherapy-induced peripheral neuropathy (nerve pain) may take 4-8 treatments to see relief. Again, the duration of the treatment response, which may last from hours to weeks, depends on the condition being treated and on the patients themselves. In my acupuncture clinic, depending on the condition being treated, I usually start with once- or twice-weekly acupuncture treatments and then gradually adjust the frequency.
