Some studies have reported that acupuncture may be effective in reducing vasomotor symptoms among postmenopausal women with breast cancer and prostate cancer patients on androgen-deprivation therapy.[43,44,45,46,47,48,49] One study randomly assigned 55 patients to acupuncture versus venlafaxine for management of vasomotor symptoms in women with hormone receptor-positive breast cancer. Acupuncture was just as effective as venlafaxine and caused fewer adverse effects.
A phase I pilot study evaluated the effect of acupuncture on tamoxifen -induced menopause symptoms. Fifteen patients with breast cancer who were taking tamoxifen were treated with acupuncture weekly for 3 months. The Greene Menopause Index was used for outcome assessments at baseline before treatment and at 1, 3, and 6 months. The results showed that anxiety, depression, and somatic and vasomotor symptoms, but not libido, were significantly improved in comparison with the baseline (P < .001).
An uncontrolled prospective case series of 50 women on tamoxifen for early breast cancer evaluated women receiving eight treatments of traditional acupuncture weekly. Mean frequency of vasomotor symptoms dropped by 49.8% (P < .0001) at the end of treatment. Seven domains of the Women's Health Questionnaire showed statistically significant improvement.
A retrospective evaluation of 194 patients with predominantly breast or prostate cancer and experiencing vasomotor symptoms found long-term relief of vasomotor symptoms associated with acupuncture and self-acupuncture. The authors suggested that overall treatment dose may be more important than point location, but favored SP6. A small RCT of EA compared with hormone therapy in women with breast cancer suggested a prolonged effect of EA on hot flushes after 24 months. Seven of 19 women initially randomly assigned to EA had 2.1 flushes in 24 hours compared with a baseline of 9.6 flushes in 24 hours. In a prospective randomized study of 84 breast cancer patients on tamoxifen treated with acupuncture versus placebo, acupuncture showed a reduction of hot flashes in both the treatment and the control arms, but there was no difference between true acupuncture and sham acupuncture. The findings from these studies are summarized in Table 4 below.
