Study Stopped
IOERT is no longer an experimental treatment and was now offered as SOC to patients experiencing IBC. As this therapy is being offered to them regardless of study participation at numerous institutions across the country.

Brief Summary
The overall objective of this study is to determine the feasibility and tolerability of single dose Intraoperative Electron Radiation Treatment ("IOERT") as definitive therapy when administered at the time of breast conserving surgery for patients with early stage breast cancer.

Outcome Measures
Primary Outcomes (1)
To evaluate change over time on the incidence of local and distance recurrence rates.
Subjects will be followed for recurrence rates at one month, three months, six months, twelve months, and then annually for up to 10 years. This will include: history and physical exam, as well as radiographic images at physician discretion and per study protocol.
1 month, 3 months, 6 months, 12 months, and then annually for 10 years.
Secondary Outcomes (1)
To evaluate changes in the short-term and long-term side effects related to IOERT
1 month, 3 months, 6 months, 12 months, and then annually for 10 years.
Study Arms (1)
IOERT arm
EXPERIMENTALIntraoperative electron radiotherapy (IOERT) is delivered after completion of the lumpectomy and sentinel node procedure. IOERT is performed on a mobile self-shielded magnetron-driven X-band linear accelerator specifically developed for use in the operating room. This machine produces megavoltage electron beams of energy ranging between 4 and 12 MeV. The radiation is delivered from the device to the tumor bed through an attached applicator. A single dose of 21 Gy calculated to the 90% depth posterior to the tumor bed will be administered and will last approximately 2.5 minutes.
Interventions
Intraoperative Electron Radiotherapy (IOERT) is delivered after completion of the lumpectomy and sentinel node procedure.

- Estrogen receptor (ER) status of positive
- Patient has clear margins \>2 mm on gross pathologic examination
- Patient is node-negative, defined as N0 (i-) or N0 (i+)
- Patient must be deemed functionally and mentally competent to understand and sign the informed consent
