A Winthrop-University Hospital Pilot Study of CyberKnife Partial Breast Radiosurgery
The purpose of this study is to determine whether noninvasive Cyberknife treatment of the breast will show equivelent or better breast conservation and cosmetic results compared to 6 weeks of daily radiation or the more invasive balloon catheter placement.
There is now a large volume of data supporting accelerated partial breast irradiation. Most of these studies have used implantable catheters into the breast. The CyberKnife, a robotic radiation device has the ability to treat the lumpectomy cavity in a noninvasive fashion and it is the purpose of this study to show that noninvasive CyberKnife treatment of the breast will show equivalent or better breast conservation results compared to 6 weeks of daily radiation or to the more invasive balloon catheter placement.
Greater/equal to 45 years old. Diagnosis consisting of ductal, medullary, papillary, colloid, tubular, or ductal carcinoma in situ.Patients involved must have a tumor size less than or equal to 3 cm. No lymph node involvement with the cancer. Surgical resection must be negative by at least 2 mm margin.
