RT Journal Article SR Electronic A1 Bittner, Dennis T1 HF of WBI Yields Improved Energy Levels Compared with CF JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 31 SP 14 OP 15 DO 10.1177/155989771431013 UL http://mdc.sagepub.com/content/14/31/14.abstract AB Previous trials comparing hypofractionation (HF) with conventional fractionation in whole breast irradiation (WBI) therapy have shown equal rates of local control, overall survival, and cosmesis. Notably, none of these trials included a tumor bed boost as part of the standard of care, although a tumor bed boost is known to decrease risk of locoregional recurrence and is widely used in the United States and Europe.
