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
