For some early-stage breast cancer patients, accelerated partial breast irradiation (APBI) using multicatheter brachytherapy following breast conserving surgery may be an excellent treatment option. In new research presented at the American Society for Radiation Oncology’s (ASTRO’s) 57th annual meeting, APBI was proven to be as effective as the current standard treatment – whole breast irradiation (WBI) – in local control, disease-free and overall survival rates.
