Long-term clinical outcomes of Pencil Beam Scanning Proton Therapy for benign and non-benign intracranial meningiomas

Since 1996, 96 patients with complex intracranial meningiomas have been treated with pencil beam scanning proton therapy (PBSPT) at XXXX. The long-term results of the present study demonstrate PBSPT as an effective and safe treatment modality for the definitive, adjuvant, postoperative, and salvage treatment of highly complex intracranial meningiomas. In addition, multiple risk factors influencing local control and overall survival were identified.
