Radiotherapy
Question
Is there clinical evidence for the usefullness of adaptive RT?
Yes and no
Yes:
Less irradiation reduces toxicity in earlier efforts in shrinking
the irradiated volume (plan of the day, expected changes)
Adaptation is a QA instrument (plan of the day, unexpected
changes)
No:
No randomized trials performed, therefore no information on
safety available
Replanning on tumor regression is not advised unless
obvious borders
