Volumetric modulated arc therapy (VMAT) is recognized for its advantages in conformal dosimetry whilst reducing dose to organs at risk (OARs) but requires increased time and resources for complex planning and quality assurance. Automated treatment planning may offer process efficiencies and reduce staff resources. Our institution developed and implemented an automated palliative planning (APP) script, allowing the radiation oncologist (RO) to generate VMAT plans with a single click. We aimed to examine the pilot implementation of APP for palliative radiotherapy.
