Meningioma

Meningiomas are the most frequent primary intracranial neoplasm, for which the treatment strategies range from observation to surgical resection and/or radiotherapy, depending on tumor size, location, histology, and growth pattern over time. Notably, stereotactic radiosurgery (SRS) and conventionally fractionated radiotherapy are well-established techniques for the treatment of benign meningiomas with high local control rates and robust long-term follow-up data. Recent studies have applied the principles of SRS to fractionated stereotactic radiotherapy (FSRT) techniques, typically for patients with large tumors or those abutting critical organs-at-risk. Fractionation schemes are variable, though early data are promising. This chapter summarizes hypofractionated radiotherapy techniques, including SRS and FSRT, for meningiomas.
