IMRT
vs
IGBT
•
For IMRT CTV-PTV margins is needed, i.e. a larger volume, compared to
brachytherapy, has to be treated .
•
D90 for IMRT was lower compared to BT for most of the patients.
•
The volumes receiving intermediate doses (>60Gy) are much larger for
IMRT.
•
The importance of very high central doses are most likely of major
importance for the excellent local control obtained with brachytherapy
Advanced BT is superior to IMRT
