6 Gy x 5 Fraction External-Beam Accelerated Partial Breast Irradiation (APBI) using IMRT Results in Superior Patient-Reported Cosmetic Outcomes Compared to 3DCRT

There have been several validated regimens of accelerated partial breast irradiation (APBI) for early-stage breast cancer, but the optimal approach especially as it relates to cosmetic outcome is uncertain. A 30 Gy in 5 fraction external-beam partial breast approach has been shown to be an effective regimen with improved cosmesis compared to conventional whole-breast radiotherapy in a randomized trial, although this was limited to use with IMRT.
