Plain English Summary
Background and study aims
Women with breast cancer treated with a type of drug called aromatase inhibitors (AIs) may experience symptoms affecting muscles and bones that can lead to treatment having to be stopped. It is important to find a safe and effective treatment strategy to manage these symptoms. The purpose of this study is to find out how well traditional Chinese medicine (TCM) works for the management of aromatase inhibitor-associated musculoskeletal symptoms and its safety.
Who can participate?
Women with a history of stage I to III breast cancer who are currently taking a third-generation AI and have ongoing symptoms affecting bones and muscles, which started or worsened after initiation of AI therapy, can participate in the study.
What does the study involve?
Participants are randomly allocated to one of two groups: the treatment group and the control group. Women in the treatment group will receive calcium, vitamin D3 and TCM granules. The control group will be given calcium, vitamin D3 and placebo (dummy) granules. Participants will complete questionnaires at the start of the study and every month after that to find out about changes in pain, movement and quality of life. Participants will undergo certain tests before and after treatment in order to find out the safety and effectiveness. Participants will be followed up after three months to assess long-term effectiveness.
What are the possible benefits and risks of participating?
All participants will receive free treatment for 3 months and a series of free tests. The symptoms of the bones and muscles could be relieved. The result of this study may help to provide evidence that
traditional Chinese medicine is safe and effective. You have to visit hospital regularly, which may be inconvenient and may disturb your routine. You will have some mild side effects when you start taking TCM granules, such as nausea. That will resolve gradually as you adapt to the smell and taste of TCM.
Where is the study run from?
The study is run from three locations:
1. Beijing Hospital of Traditional Chinese Medicine, China
2. Beijing Cancer Hospital, China
3. Guang' anmen Hospital, China Academy of Chinese Medical Sciences, China
When is the study starting and how long is it expected to run for?
The study will start in August 2013 and will end in December 2015.
Who is funding the study?
Beijing Municipal Science and Technology Commission (China).
Who is the main contact?

Aromatase inhibitor-associated musculoskeletal symptoms
The 84 eligible participants are randomly allocated to two different groups:
1. Treatment group: Calcium carbonate and vitamin D3 tablets (Ca 600mg+ vitD3 125IU per tablet, 2 tablets per day) twice a day for 3 months, Chinese medicine granules (12.375g granules per bag, 2 bags per day) twice a day for 3 months.
2. Control group: Calcium carbonate and vitamin D3 tablets (Ca 600mg+ vitD3 125IU per tablet, 2 tablets per day) twice a day for 3 months, placebo granules (12.375g granules per bag, 2 bags per day) twice a day for 3 months.
The patients receive assessments every month during the treatment and the third month after the treatment.
Primary outcome measures
1. The Brief Pain Inventory-Short Form (BPI-SF) to evaluate general pain
2. Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index to assess joint pain, stiffness, and functional status in the knees.
3. The Modified Score for the Assessment and quantification of Chronic Rheumatoid Affections fo the hands (M-SACRAH) to assess joint pain, stiffness, and functional status in the hands.
The outcome measures above will be assessed before the treatment, at 1 month, 2 and 3 months during the treatment, the assessments will be repeated at the third month after the treatment.
Secondary outcome measures
1. The Functional Assessment of Cancer Therapy breast cancer-specific quality of life tool (FACT-B) to evaluate quality of life of patients with breast cancer.
2. TCM symptoms scale to evaluate TCM syndrome (deficiency of liver and kidney, qi and collaterals stagnation).
3. Bone Mineral Density (BMD) to evaluate bone density and bone metabolism objectively
4. Bone Metabolic Markers (calcium, phosphorus, alkaline phosphatase, osteocalcin, calcitonin) to evaluate bone density and bone metabolism objectively
FACT-B and TCM syndrome will be assessed before the treatment, at 1 month, 2 and 3 months during the treatment, the assessments will be repeated at the third month after the treatment. BMD and bone metabolic markers will be assessed before and after the treatment.
