Clinical Trial Summary

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).
