ENT tumours
Tumours of the ENT area for which proton therapy is a possible treatment are periorbital tumours, or ones reaching the base of the skull or the cavernous sinuses, or with intracranial extension, or perineural extensive in patients treated for curative purposes and having a long life expectancy.
With regard to clinical studies, squamous cell carcinomas, cavum cancers and sinus cancers of the face appear as indications that could benefit from the contributions of proton therapy in terms of therapeutic efficacy or acute and late toxicity. These indications need to be discussed beforehand in a Multidisciplinary Consultation Meeting (MCM). This treatment is carried out as part of clinical research trials.
