Seeking to improve response to radiation therapy and prevent local recurrences in high-risk women.
Clinical studies are ongoing to test a gene signature to predict the likelihood and timing of local recurrence following breast cancer surgery and radiation therapy.
These studies may lead to new treatment options for women at high-risk for recurrence and improve ability the accuracy of predicting a high risk of breast cancer recurrence.
Clinical trials have shown that the addition of radiation therapy following both breast-conserving surgery and mastectomy can significantly reduce the risk of local recurrence of early breast cancer. Despite the efficacy of this trimodal therapy, some women will develop locoregional recurrence (i.e., in the breast or lymph nodes) after standard treatment, and some women do not benefit from radiation.
Currently, no test can accurately distinguish women who may need more aggressive treatment from those at sufficiently low risk or predict who is likely to recur following surgery and radiation.
Dr. Pierce's previous BCRF research resulted in development of a radiation response signature that accurately identifies women likely to develop early local recurrences after radiation therapy. This year, the team will continue to investigate the biological mechanisms underlying the recurrence signatures and further validate it in additional patient cohorts.
These efforts may lead to a better ability of clinicians to identify the women truly at high risk of breast cancer recurrence.
Dr. Pierce completed residency in Radiation Oncology at Pennsylvania and was a senior investigator at the National Cancer Institute (NCI). She joined the Department of Radiation Oncology at Michigan in 1992, where she is currently Professor of Radiation Oncology and Vice Provost for Academic and Faculty Affairs.
She has published more than 100 papers and book chapters on aspects of radiotherapy (RT) in the treatment of breast cancer, and her work has been funded by the NCI, Department of Defense Funds for Breast Cancer Research, the Breast Cancer Research Foundation, Komen for the Cure, BCBS of Michigan and private industry.
Her research focuses on the use of RT in the treatment of breast cancer, with emphasis upon contemporary RT treatment planning techniques, the use of RT in the presence of a breast cancer susceptibility gene, and use of radiosensitizing agents.
