A Study of Adaptive Radiotherapy of Head-neck Cancer Using Daily Replanning and Optimization of the Treatment Plan.

Summary

Radiotherapy of head-neck cancer is associated with significant side effects. Using daily online adaptive radiotherapy to account for the changing anatomy, radiation to organs at risk can be lowered. We will investigate whether this is feasible and associated with a reduction in the risk of toxicity.
