Whole‐breast irradiation with lumpectomy cavity boost and regional nodal irradiation: Dosimetric comparison of 3D‐CRT using sequential boost and dual partial‐arc VMAT using simultaneous integrated boost

Abstract

To compare volumetric modulated arc therapy (VMAT) with simultaneous tumor bed boost (dpSIB‐VMAT) to the whole breast and regional nodal irradiation (RNI) against standard three‐dimensional conformal radiotherapy plus RNI with sequential tumor bed boost (3D‐CRT‐seqB).
