Breast Cancer Clinical Trial
Normal Tissue Oxygenation Following Radiotherapy
Summary
This study involves women who have had a diagnosis of breast cancer, and have had a lumpectomy with radiation treatments completed in the past year.
The study will determine the level of oxygen in the skin of the breast that has been radiated, compared with the normal skin of the opposite breast.
The purpose of this study is to determine if there is a decrease in oxygen levels in the skin which has been radiated, hopefully to find a treatment to limit skin damage caused by radiation treatments, for women with breast cancer in the future.
Full Description
Successful completion of this study will provide data on changes in oxygenation in irradiated tissues. If changes are documented, this study would provide evidence supporting current models of tissue injury following radiotherapy. In addition, these data may provide a mechanistic rationale for clinical approaches to ameliorate the toxicities of radiotherapy. Finally, if a correlation exists between tissue oxygenation and toxicity, the rapid and simple tissue oxygenation test may provide a quantitative measure of toxicity and allow earlier and more precise assessment of both toxicity and efficacy of ameliorative therapies.
