Breast Cancer Clinical Trial
Single Dose Partial Breast Radiotherapy
Summary
This study seeks to determine the maximum tolerated dose of a single-dose partial breast radiation given before lumpectomy using a radiosurgery technique. Lumpectomy will be performed within 3 weeks (+/- 1 week) of completing radiation.
Full Description
This study will assess the safety of partial breast radiosurgery as measured by the incidence of acute toxicity and wound healing complications in three dose cohorts.
Patients will be enrolled in cohorts of 8 patients starting at dose level 1 (15 Gy). If 2 or more dose limiting toxicities (DLTs) are observed at dose level 1, the trial will be stopped for evaluation and consideration of revision. If at most one DLT is observed then escalation continues to the next dose level. The cohorts will escalate by 3Gy up to 21 Gy of irradiation.
