Multi-institutional Prospective Pilot Study of Definitive Breast Radiation Therapy for Invasive Breast Cancer Patients Not Undergoing Definitive Surgery
Alexander Stessin
Summary
The purpose of this study is to find out if adding radiation therapy to routine medications for breast cancer helps in reducing and preventing the cancer from getting worse. Patients with a locally advanced breast cancer who cannot, or do not want to, undergo surgery are eligible to participate. Participation in this study does not prevent you from undergoing surgery in the future.
Description
Patients who cannot undergo surgical resection for either breast cancer or local control of metastatic cancer have limited effective treatment options. Treatments typically employed in the adjuvant setting have been found in the definitive setting to be inferior to surgery followed by adjuvant therapy. This raises the necessity of evaluating the use of ablative doses of radiation to provide durable local control of the tumor in such patients. Indeed, there is growing evidence that RT is effective in the adjuvant setting. This is a study of concurrent ultra-hypofractionated whole breast whole b…
