Frameless Hypofractionated Gamma Knife Radiosurgery for Residual or Recurrent Craniopharyngioma.

The management of craniopharyngioma requires a multidisciplinary approach, and irradiation represents effective treatment option for residual/recurrent tumors after surgery. To the best of our knowledge, this is the first study that addresses the efficacy of frameless hfGKRS in managing craniopharyngiomas over sufficient follow-up.
