“…53,57,65 A recent report from Japan described long-term toxicities after proton therapy in 90 patients with nasal cavity, paranasal sinus, or skull base malignancies. 52 Late toxicities reached grade 3 in 17 patients (19%) and grade 4 in 6 patients (7%) (encephalomyelitis infection in 2 patients, optic nerve disorder in 4 patients).…”

“…Regarding the clinical outcomes after PBT, several studies including a study from our institution demonstrated that 5-year OS ranged from 70–80%, although the histological types of patients analyzed were not homogenous. These results indicated that clinical outcomes were slightly better than those after conventional radiation therapy [9, 14, 15, 16]. The main advantages of radiation therapy for nasal cavity and paranasal malignancies are to preserve organs and their functions by delivering enough total dose to the tumors while sparing excessive doses to the adjacent critical normal structures such as the brain, brainstem and the optic structures.…”

“…In cases where the disease has spread deeply into the intracranial region, surgical approaches are often complicated by the risk of serious functional deformity and a lack of satisfactory surgical clearance [7, 8]. Therefore, definitive radiation therapies (RTs) including 3D-conformal radiation therapy (3DCRT) or intensity modulated radiation therapy (IMRT) and proton beam therapy (PBT) are often performed as an alternative treatment [2, 4, 9]. …”

“…The surgical margin was negative for cancer cells. In January 2008, she had developed a recurrence in the left upper eyelid, and underwent radiotherapy with a total dose of 57.6 Gy of proton beam therapy followed by orbital exenteration of the left eye [11,12]. In July 2012, positron emission tomography–computed tomography (PET-CT) revealed a solitary pulmonary nodule 0.5 cm in size in the right upper lobe of the patient’s lung, which had increased to 1.1 cm by September 2013 (Figure 1A).…”
