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
