Primary Outcome Measures:
  • Maximum Tolerated Dose [ Time Frame: 24 months ] [ Designated as safety issue: Yes ]
    as measured by the incidence of acute toxicity and wound healing complications


Secondary Outcome Measures:
  • Local control [ Time Frame: 2 yrs ] [ Designated as safety issue: No ]
  • Cosmetic outcome [ Time Frame: 2 yrs ] [ Designated as safety issue: No ]

Estimated Enrollment: 32
Study Start Date: January 2010
Estimated Study Completion Date: January 2013
Estimated Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Single dose radiosurgery
A single dose of radiation given in radiosurgery technique about 3 weeks before lumpectomy.
 Radiation: Radiosurgery
Single dose or radiation in 15Gy, 18Gy or 21Gy
Other Names:
  • Radiosurgery
  • External beam radiation therapy

Detailed 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.
