Popis: Stereotactic radiosurgery (SRS) is feasible for malignant glioma; however, delivering the optimal radiation dose with sufficient large-volume coverage is a major concern. We aimed to investigate the clinical efficacy and safety of fractionated SRS (fSRS) versus single-session SRS (sSRS) for malignant gliomas. We retrospectively reviewed 58 malignant glioma patients who underwent gamma knife SRS from January 2015 to December 2018. Forty-one underwent sSRS, and 17 underwent fSRS. Median dose for fSRS was 28 Gy (range 24–35 Gy), with a median dose of 6 Gy per fraction (range 5–7 Gy). Patients received 4 or 5 fractions on consecutive days. Median dose for sSRS was 18 Gy (range 11–25 Gy), with a median isodose of 50% (range 50–65%). Mean target volumes were 5.9 and 19.3 cc for sSRS and fSRS, respectively (p
