Radiation induced optic neuropathy after pencil beam scanning proton therapy for skull-base and head and neck tumours.

CONCLUSION: This data suggests that high-dose PBS PT for skull base and H&N tumours is associated with a low prevalence of RION. Caution should be however exercised when treating elderly/hypertensive patients with tumours abutting the optic apparatus.
ADVANCES IN KNOWLEDGE: This is the first study reporting the risk of developing RION following proton therapy with PBS technique, demonstrating the safety of this treatment.
