title: A new method for treatment of unresectable, recurrent brain tumors with single permanent high-activity 125iodine brachytherapy.
abstract: We describe a new method for treating unresectable recurrent brain tumors in previously-irradiated patients with localized high-dose intracranial brachytherapy of 10,000-30,000 rads using permanent implantation of a single high-activity 125Iodine seed. For unresectable recurrent previously-irradiated pituitary tumors, a single high-activity 125Iodine seed is permanently implanted into the center of the tumor with an interstitial needle inserted under fluoroscopic guidance via a transsphenoidal approach. For unresectable recurrent meningiomas, a single high-activity seed is permanently implanted into the tumor at craniotomy. The clinical course of five patients treated by this method is described. Excellent long-term local control was obtained in all implanted cases. There were no intraoperative, postoperative, or chronic complications.
