Xeloda (Capecitabine) and External Beam Radiation
The goal of this clinical research study is to find out if Xeloda® (capecitabine) and radiation therapy can help to control breast cancer that did not respond well to chemotherapy.
The safety of this study treatment will also be studied.

Primary Purpose: Treatment
|Official Title:||A Phase II Study of Preoperative Capecitabine and Concomitant Radiation in Women With Advanced Inflammatory or Non-Inflammatory Breast Cancer|
- Tumor Response (complete response + partial response) as measured by Response Evaluation Criteria in Solid Tumors (RECIST) criteria [ Time Frame: Assessed 4 weeks (+/- 4 days) after the last scheduled day of radiation ]Tumor responses according to RECIST. Complete Response (CR): Disappearance all target lesions; Partial Response (PR): >30% decrease in sum of the LD of target lesions, taking as reference the baseline sum LD; Progressive Disease (PD): >20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started.
|Study Start Date:||June 2009|
|Estimated Primary Completion Date:||July 2017 (Final data collection date for primary outcome measure)|
Experimental: Radiation Therapy + Capecitabine
Capecitabine 825 mg/m2 twice a day. One of the two daily doses of capecitabine should be taken approximately 2 hours before receiving radiotherapy. The first day of Capecitabine is same day that radiotherapy is started, and last day that Capecitabine is given is last day of radiotherapy. Capecitabine administered only on days patient receives radiation therapy.
Radiation therapy dose 50-57 Gy to initial clinical target volume (CTV, gross disease + tissue at risk for micrometastatic disease including margin around gross disease and draining regional lymphatics).
Radiation: Radiation Therapy
50-57 Gy per faction once or twice a day, 5 days a week, for about 5 -7 weeks, about 15-30 minutes each time.
Other Names:Drug: Capecitabine
During 5-7 weeks of radiation therapy, 825 mg/m2 (pills) by mouth, 2 times a day, about 12 hours apart, 30 minutes after eating food and about 2 hours before radiation therapy.
Other Name: Xeloda
The Study Treatment:
Radiation therapy and capecitabine are both designed to interfere with the growth of cancer cells.
If you are found to be eligible to take part in this study, you will receive radiation therapy once or twice a day, 5 days a week, for about 5 -7 weeks. The schedule and number of weeks will be the doctor's decision based on the type of breast cancer.
The radiation treatments will take about 15-30 minutes each time.
You will take the Capecitabine pills by mouth every day during the 5-7 weeks that you receive radiation therapy. The pills should be taken 2 times a day, about 12 hours apart, 30 minutes after eating food. On the radiation therapy days, you will take capecitabine about 2 hours before the radiation therapy.
You will be given a pill diary in which you should record what time you take each dose of capecitabine.
Once a week while you are receiving study treatment, you will have a physical exam.
Length of Study:
You may remain on study treatment for up to 7 weeks. You will be taken off study treatment early if the disease gets worse or intolerable side effects occur.
Based on the status of the cancer, if you become eligible to have surgery after radiation, you will be referred to a surgeon to discuss that option.
At Month 3 after finishing radiation therapy (or surgery, if applicable), you will have a positron emission tomography / computed tomography (PET/CT) scan or ultrasound to check the status of the disease.
At Months 9, 17, and 29 after finishing radiation therapy or surgery, you may have a PET/CT scan, ultrasound, and/or routine blood tests if your doctor thinks it is needed. The amount of blood drawn, if any, will be the doctor's decision based on routine care.
This is an investigational study. Capecitabine is commercially available and FDA approved to treat breast cancer that has spread. Radiation therapy is also commonly used to treat breast cancer. The combination of capecitabine and radiation therapy is commonly used to treat rectal cancer.
At this time, it is considered investigational to give the combination of capecitabine and radiation therapy to patients with breast cancer.
Up to 60 patients will take part in this study. All will be enrolled at M. D. Anderson.
