Acupuncture is an effective and longer-lasting measure in managing the common debilitating side effects associated with breast cancer treatment, a new study has found.
The study also shows that there were additional benefits to acupuncture treatment for breast cancer patients, such as an increased sense of well being, more energy, and in some cases, a higher sex drive, that were not experienced in those patients who underwent drug treatment for their hot flashes.
"Our study shows that physicians and patients have an additional therapy for something that affects the majority of breast cancer survivors and actually has benefits, as opposed to more side effects," Eleanor Walker, M.D., lead author of the study and a radiation oncologist at the Henry Ford Hospital Department of Radiation Oncology in Detroit, said.
"The effect is more durable than a drug commonly used to treat these vasomotor symptoms and, ultimately, is more cost-effective for insurance companies," Walker added.
The reduction in hot flashes lasted longer for those breast cancer patients after completing their acupuncture treatment, compared to patients after stopping their drug therapy plan.
Eighty percent of women treated for breast cancer suffer from hot flashes after being treated with chemotherapy and/or anti-estrogen hormones, such as Tamoxifen and Arimidex.
Although hormone replacement therapy is typically used to relieve these symptoms, breast cancer patients cannot use this therapy because it may increase the risk of the cancer coming back.
As a treatment alternative, patients are generally treated with steroids and/or antidepressant drugs.
However, many women decide against this treatment choice because of potential side effects, including weight gain, nausea, constipation and fatigue.
In the randomized clinical trial, the researchers compared acupuncture treatment to venlafixine for 12 weeks to find out if acupuncture reduced vasomotor symptoms in breast cancer patients receiving hormonal therapy and produced fewer side effects than venlafaxine.
The study involved 47 breast cancer patients who received either Tamoxifen or Arimidex and had at least 14 hot flashes per week. Results show that acupuncture reduces hot flashes as effectively as venlafaxine, with no side effects, and also provides additional health benefits to patients.
The study will be presented on September 24, 2008, at the American Society for Therapeutic Radiology and Oncology's 50th Annual Meeting in Boston.
