Although patient weight loss and parotid volume shrinkage was observed, overall, there was no significant excess dose to the organs at risk.
No replanning was felt necessary for this patient cohort, but a larger patient sample will be investigated to further confirm these results. Nevertheless, kilovoltage CBCT is a valuable tool for patient setup verification and monitoring of dosimetric variation during radiotherapy.
