Vasomotor symptoms are common adverse effects of antiestrogen hormone treatment in conventional breast cancer care. Hormone replacement therapy is contraindicated in patients with breast cancer. Venlafaxine (Effexor), the therapy of choice for these symptoms, has numerous adverse effects. Recent studies suggest acupuncture may be effective in reducing vasomotor symptoms in menopausal women. This randomized controlled trial tested whether acupuncture reduces vasomotor symptoms and produces fewer adverse effects than venlafaxine. Patients and Methods Fifty patients were randomly assigned to receive 12 weeks of acupuncture (n 25) or venlafaxine (n 25) treatment. Health outcomes were measured for up to 1 year post-treatment. Results Both groups exhibited signiﬁcant decreases in hot ﬂashes, depressive symptoms, and other qualityof-life symptoms, including signiﬁcant improvements in mental health from pre- to post-treatment. These changes were similar in both groups, indicating that acupuncture was as effective as venlafaxine. By 2 weekspost-treatment, the venlafaxine group experienced signiﬁcant increases in hotﬂashes, whereas hot ﬂashes in the acupuncture group remained at low levels. The venlafaxin egroup experienced 18 incidences of adverse effects (eg,nausea,drymouth,dizziness,anxiety), whereas the acupuncture group experienced no negative adverse effects. Acupuncture had the additional beneﬁt of increased sex drive in some women, and most reported an improvement in their energy, clarity of thought, ands enseofwell-being. Conclusion Acupuncture appears to be equivalent to drug therapy in these patients. It is a safe, effective and durable treatment for vasomotor symptoms secondary to long-term antiestrogen hormone use in patients with breast cancer.
