Breast-Conserving Radiotherapy with Simultaneous Integrated Boost—A Dosimetric Comparison of 3DCRT, VMAT and IMRT: Do We Really have a Better Plan?

Background and Purpose The availability of more advanced technology like hypo-fractionation has the potential of being the new standard of care in breast cancer. This study evaluates whether 3DCRT with a field-in-field technique (FIF) and a simultaneous integrated boost (SIB) could provide a dosimetrically comparable plan delivered to VMAT or IMRT.
