Tumour bed boost radiotherapy (RT) following breast conserving surgery reduces local recurrence in high-risk disease. There is recent debate over challenges to accurately localise tumour bed for RT boost delivery following volume replacement oncoplastic breast surgery (VR-OBS).
This review evaluates the reporting of RT boost following VR-OBS in the literature published between January 2010 and December 2021. This review was in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA).
Nine studies met the inclusion criteria (n = 670 patients), and RT boost was used in eight studies. Boost was administered in total to 384 patients (62.5% of irradiated patients). Only two studies reported boost planned target volumes and only one compared these against surgical specimen volumes. RT boost was not reported in most published studies on VR-OBS.
Future prospective research is strongly needed to evaluate long-term outcomes of VR-OBS following RT boost, especially on breast cosmesis and patients' satisfaction.
