Second Gamma Knife Treatment for Trigeminal Neuralgia: Anterior Target Spacing and 25 Gy as the Second Dose.

Objective Gamma Knife® radiosurgery (GKRS) has been demonstrated to be a well-known approach for treating patients with medical refractory trigeminal neuralgia (TN). Herein, the authors review the outcomes of pain among a large cohort of patients who had undergone a second GKRS delivered at a significantly reduced dose. Methods The authors conducted a prospective analysis of patients who have undergone two GKRS procedures between the years 2012 to 2021 at one institution.

Gamma knife radiosurgery of epidermoid tumors: an analysis of treatment results of eight patients.

Background: Epidermoid tumors (ETs) of the central nervous system (CNS) are rare tumors that typically occur in the 4 decade. They typically grow around vital neurovascular structures which makes surgical treatment difficult. The objective of this paper is to report on the effectiveness and safety in the management of epidermoid tumors with gamma knife surgery (GKS).

Long-Term Results of Gamma Knife Radiosurgery for Glomus Tumors: An Analysis of 32 Patients.

Background Glomus jugulare tumors are rare slow-growing hypervascular tumors that arise from the paraganglia of the chemoreceptor system within the jugulare foramen of the temporal lobe. The historical standard treatment has been surgical resection, but because of their high vascularity and involvement with cranial nerves (CNs), Gamma Knife radiosurgery (GKRS) has been advocated as an alternative. The goal of this study is to update and report long-term results of GKRS to achieve local control and symptomatic improvement and to reduce morbidity and mortality when treating glomus jugulare tumors.

Radiosurgery for brain metastases from ovarian cancer: an analysis of 25 years' experience with Gamma Knife treatment.

Purpose: We present our results in the treatment of brain metastases (BM) from ovarian cancer using Gamma Knife Radiosurgery (GKRS) over the last 25 years in a single institution.

Background: Gamma Knife Radiosurgery has become increasingly important in the management of brain metastases from ovarian cancer due to improving results from systemic disease and the need for better outcomes.

Material And Methods: The medical records of 9 patients with brain metastases from ovarian cancer treated with GKRS between 1993 and 2018 were reviewed.

Primary Central Nervous System Lymphoma (PCNSL): Analysis of Treatment by Gamma Knife Radiosurgery and Chemotherapy in a Prospective, Observational Study.

Background: Primary central nervous system lymphoma (PCNSL) is a rare cancer accounting for less than 3% of primary brain and central nervous system (CNS) tumors. Tissues involved include the brain parenchyma, leptomeninges, eyes, and spinal cord. High-dose methotrexate (MTX) is the gold standard for newly diagnosed PCNSL.

Pineal tumors: analysis of treatment results in 20 patients.

Object: The authors evaluate their results when using gamma knife surgery (GKS) in the management of patients with tumors in the pineal region.

Methods: This is a retrospective clinical evaluation of 20 patients with primary tumors of the pineal region treated with GKS from November 1994 through August 2003. There were 13 germ cell tumors, two pineoblastomas, two low-grade gliomas, one primitive neuroectodermal tumor, one teratoma, and one pineocytoma.

Role of radiosurgery in craniopharyngiomas: a preliminary report.

Purpose: The purpose of this retrospective review is to evaluate our experience using radiosurgery in the management of craniopharyngiomas.

Materials And Methods: Fourteen patients, 6 males and 8 females, ages ranging from 3 to 44 years of age, were treated with radiosurgery from February 1994 through December 2000 for primary or recurrent craniopharyngioma. There were two adults and 12 children.
