Radiobiology and Radiation Therapy of Skull Base Tumors

Skull base tumors can be separated into three broad groups: (i) tumors arising from neural and vascular structures and meninges of the base of the brain (e.g., schwannoma, meningioma, pituitary adenoma, craniopharyngioma, paraganglioma); (ii) tumors arising from the skull base (e.g., chordoma, chondrosarcoma, osteosarcoma, plasmacytoma); and (iii) tumors arising from below the skull base (e.g., nasopharyngeal carcinoma, paranasal sinus tumor).
