How to reduce boost volume ?

Does a pre-operative CT in treatment position help ?

•

Boersma et al (2012): •

Boost CTV 42 cc to 36 cc (translating in V95 from 117cc to 105cc)

•

Verhoeven et al (2016) •

No difference in size of CTV with or without pre-op CT..

•  No clinically significant reduction in V95
