ABSTRACT

The definitive treatment of head and neck cancers requires a multidisciplinary approach in which radiotherapy plays a pivotal role. The standard radiation regimen for head and neck cancers typically involves administering 30-37 fractions of treatment. The impact of alterations in patient anatomy and tumor biology that may arise throughout the course of treatment on the ultimate end result is a subject of scientific interest. The technique known as “adaptive radiotherapy” involves the modification of the initial treatment plan in response to changes observed over the course of treatment, with the objective of creating an improved treatment plan. This technique involves tailoring the therapy to account for several factors, including potential changes in the tumor volume, alterations in tumor biology, weight loss, muscle atrophy, inflammation, and normal tissue changes that may arise throughout the course of treatment. The primary objective is to identify the most optimal definitive treatment strategy. This review aims to explore the utilization of positron emission tomography in adaptive radiotherapy approaches for head and neck cancers, drawing upon relevant literature references.
