Summary
Brief summary (as posted)
Single arm, prospective, multi-center, non-randomized study of subjects treated with single fraction, intra-operative radiation therapy at the time of lumpectomy for early stage breast cancer.To assess the rate of ipsilateral breast tumor recurrence in subjects treated with the Xoft Axxent Electronic Brachytherapy System when used for single-fraction, intra-operative radiation therapy treatment of early stage breast cancer when compared to whole breast irradiation (WBI) at 5 years of follow-up. The results of this single arm study will be compared to whole breast irradiation (WBI).

Clinical staging of Subject's tumor(s) must meet AJCC Tumor Classification: Tis, T1 or T2 (\< 3 cm), N0, M0 6. Subject presenting with bilateral breast cancer may be enrolled if BOTH cancers meet all of the inclusion and none of the exclusion criteria 7. Women of child-bearing potential must have a negative pregnancy test within one week of IORT treatment 8. Women of child-bearing potential must agree to use adequate contraceptive precautions (defined as intrauterine devices, surgical contraceptives or a combination of condom and spermicide) from the time of negative pregnancy test through completion of the radiation treatment period General Exclusion Criteria 1. Subject is pregnant or nursing 2. Subject has significant auto-immune disease 3. Subject has a pacemaker present in the field of radiation or quadrant of the breast cancer 4. Subject has multi-focal breast cancer where the sum of the individual tumor sizes (greatest diameters) are \> 3 cm Subject has multi-centric breast cancer 5. Subject has known lympho-vascular invasion 6. Subject has invasive lobular cancer 7. Subject has undergone neo-adjuvant chemotherapy or neo-adjuvant endocrine therapy for current breast cancer 8. Subject has a history of recurrent breast cancer in the ipsilateral breast 9. Subject has had previous radiation exposure of the involved breast 10. Subject has BRCA 1 or 2 mutations. Note: Testing will only be required for subjects presenting with bilateral breast cancer; testing is not required for unilateral cancers 11. Subject has contraindications for radiation 12. Subject considered by the Investigator to be high-risk for breast conservation surgery and/or intra-operative radiation therapy 13.
