Acupuncture for Chronic Lymphedema
This study is being done because women have arm swelling for more than 6 months despite wrapping and other treatments. This swelling is called lymphedema. It is the back up of lymph system fluid that causes swelling in the arm. The swelling can just happen, but more commonly it is caused when lymph nodes are removed during cancer surgery. It can develop right after breast cancer treatment or weeks, months or even years later. In our preliminary research, the investigators found that more than 1/3 of the 33 patients showed at least a 30% reduction in lymphedema following acupuncture treatment and there were no serious adverse events during the treatment or 6 month followup.
This study will include a larger group of patients. Patients will be assigned to one of two groups, and results of the groups will be compared to see if acupuncture can reduce lymphedema and whether the effect lasts after acupuncture treatment is completed.

- difference in the extent of lymphedema [ Time Frame: 2 years ] [ Designated as safety issue: No ]The difference in the extent of lymphedema between groups will be assessed with an analysis of covariance (ANCOVA) model with extent of lymphedema after 6 weeks as the outcome with treatment group and baseline extent of lymphedema as covariates. We will report a two-tailed p-value and a 95% confidence interval for the difference between groups.
- effectiveness [ Time Frame: 2 years ] [ Designated as safety issue: No ]of acupuncture for the treatment of breast cancer-related lymphedema (BCRL) as measured by arm circumference after 6 weeks of acupuncture treatment.
- differences between treatment group for bioimpedance [ Time Frame: 2 years ] [ Designated as safety issue: No ]ANCOVA models will be used to assess differences between treatment group for bioimpedance. The 6-week score will be the outcome and treatment group, baseline score, and randomization stratum will be included as covariates. We will report the two-tailed p-value and a 95% confidence interval for the difference between groups.
- safety [ Time Frame: 1. 5 years ] [ Designated as safety issue: Yes ]Severity will be graded as "serious" or "non-serious". Serious AEs are those that require hospitalization, lead to death or disability or require urgent medical attention to prevent death or disability. The intensity of non-serious AEs will be graded as mild, moderate or severe.

Patients in the acupuncture group will receive acupuncture treatment twice weekly for six consecutive weeks.
Each treatment will be 30 minutes in duration. Patients will receive two acupuncture treatments each week for six consecutive weeks. Patients will be advised to continue their standard lymphedema treatments such as exercise or use of compression garments if these were in use prior to clinical trial participation.
Patients in the wait-list control group will cross over and receive acupuncture twice weekly for 6 consecutive weeks.
For participants in the wait-list control group, follow-up objective and subjective assessments of lymphedema will be performed after approximately 6 weeks on the wait-list, before onset of acupuncture treatment, following 6 weeks of acupuncture treatment and about 3 months after completion of treatment. BMI will be measured at the same timepoints.
