MammoSite® accelerated partial breast irradiation: A single-institution outcomes analysis with 2 years of followup

MammoSite® radiation therapy system demonstrates excellent local control and cosmetic outcome with extended followup. The maximum skin dose should be kept below 100% to reduce late effects on skin and improve cosmetic outcome. The persistence of seroma is higher with intraoperative placement of the catheter, and therefore postoperative placement is preferred.
