Proton Radiation Therapy in Head and Neck Cancers

Proton therapy (PT) is one of the latest advancements in the treatment modalities of cancers. PT is specifically used to treat HnN cancer patients due to its less toxic effects on the surrounding critical structures. Keeping in view the opportunities for further advancements, there has been quite a lot of literature covering PT in HnN cancer patients. However, there has not been a compiled study that compares the toxicities, overall survival (OS), local control (LC), and quality of life (QoL) of PT with that of IMRT. The objective of this review is to compile & summarize the literature available on the toxicities, OS, LC, and QoL in HnN cancer patients post-proton therapy.
