Background: Obesity and weight gain are significant concerns for breast cancer survivors. Obesity at diagnosis of breast cancer is an established negative prognostic factor and post-diagnosis weight gain may increase risk for recurrence. Studies suggest that decreased dietary fat intake and weight loss after breast cancer diagnosis may decrease breast cancer recurrence. Various interventions such as dietary modification, physical activity, individualized counseling and cognitive behavioral therapy, have been studied in order to identify strategies for weight loss in breast cancer survivors. Methods: We enrolled obese women who have been diagnosed and treated for breast cancer in a twelve week weight loss program. The participants were randomized into two groups: weight loss acupuncture plus nutrition intervention or nutrition intervention alone. Women in the acupuncture group received weekly body and/or auricular acupuncture once a week, in addition to attending the online group-based nutritional education sessions in which all study participants partook. All study participants’ were assessed at the end of twelve weeks, with follow-up at twenty-four weeks, then every 3 months for the first year, then every 6 months until year two, to evaluate weight loss maintenance. Results: Twenty breast cancer patients initially participated in the study, with a final of 18 completing the intervention. The BMI ranged from 28.9-49.1 for the group. 67% of patients were stage 1, 27% were stage 2 and 5% were stage 3. Treatment included endocrine therapy, Her2 therapy and chemotherapy for 72%, 17% and 94% of patients respectively. There was a trend towards improved weight loss with the combination intervention; however this was not durable nor statistically significant. Conclusions: We examined whether adding weight loss acupuncture to a nutrition education program for weight loss could improve short and long term weight loss among breast cancer survivors post treatment. Continued efforts to identify appropriate weight management interventions aimed at promoting overall health and long term survivorship are needed. Clinical trial information: NCT02081612
