Discussion: Clinical Relevance
▪
Replanning … when and on what volume?
▪
Target size change and tumor-to-OAR distances should be considered
when deciding whether a lung SBRT patient would benefit from adaptive
treatment (Yujiao Qin et al.)
▪
Do not start with replanning when implementing lung SBRT
▪
Safety issues
▪
The relation between fiducial markers and tumor may have changed
▪
Check tumor position with respect to the organs at risk and adapt the
plan if organs at risk constraints are violated
