This study aimed to report the outcomes of SRS\/stereotactic radiotherapy (SRT) or FSRT and compare tumor control in a single center.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Methods: <\/jats:title>\n<jats:p>From 2014 when TrueBeamTM STx with Novalis was introduced in our hospital to 2021, 21 patients underwent SRS\/SRT or FSRT with gamma knife surgery (GKS) and Novalis. We have selected the radiation modalities considering mainly the distance of the optic nerve and chiasm. Imaging and clinical follow-up data were sent and reviewed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Results: <\/jats:title>\n<jats:p>The mean age was 52 years and there were 11 men. Of the 21 total patients, three experienced SRS (GKS, 50% isodose 12\u201315 Gy), five underwent SRT (GKS or Novalis, 19.5\u201324 Gy 3 fractions), and 13 patients underwent FSRT (Novalis, 54 Gy 30 fractions). The median follow-up was 32.6 (range 17\u201344) months after SRS\/SRT and 34.0 (range 4\u201361) months after FSRT. In the SRS\/SRT group, the mean tumor volume decreased from 1.103 to 0.131 cm<jats:sup>3<\/jats:sup> (<jats:italic>P<\/jats:italic> &lt; 0.01), and in the FSRT group, from 3.015 to 1.012 cm<jats:sup>3<\/jats:sup> (<jats:italic>P<\/jats:italic> &lt; 0.01). No radiation-induced optic neuropathy and other acute toxicity occurred.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st4\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>Craniopharyngioma can be expected to have very good tumor control by selecting SRS\/SRT or FSRT depending on the distance between the optic nerve and the
