A cost comparison analysis of partial versus whole-breast irradiation after breast-conserving surgery for early-stage breast cancer

Conclusions: Based on societal cost considerations, WBRT-AC appears to be the preferred approach. If one were to pursue a partial-breast RT regimen to minimize patient costs, it would be more advantageous from a societal perspective to pursue external beam-based approaches such as APBI-3D-CRT or APBI-IMRT in lieu of the brachytherapy-based regimens.
