Smart radiotherapy aims to spare saliva glands in head and neck cancer patients

This study tested a new type of radiation therapy that adjusts the treatment beam each day based on the patient's current anatomy. The goal was to see if this daily adaptive approach could reduce chronic dry mouth (xerostomia) compared to standard radiation in 50 people with head and neck cancer. Participants were randomly assigned to either standard or adaptive treatment, and their dry mouth symptoms were measured after one year.
