Study Summary

This phase IV trial studies the side effects of intraoperative radiation therapy and how well it works in treating patients with breast cancer undergoing breast-conserving surgery. Delivering radiation one time to the area where the tumor was removed while the patient is still in the operating room may kill any residual tumor cells and may be as effective as standard radiation therapy in patients with early stage breast cancer.

Primary Outcome

Local tumor control is defined as no recurrent tumor in the ipsilateral breast. Patients will be regularly monitored as per the individual center's policy provided this meets the minimum trial criteria for follow-up with physical examination at least every 6 months for 3 years and yearly at 4 and 5 years post-treatment. Confirmation of recurrence will follow clinical examination and cytology or biopsy. The two patient cohorts will not be separated for the analysis regarding local control.
