Stereotactic body radiation therapy for liver metastases: Clinical outcomes and literature review.

Background And Aim: The role of stereotactic body radiation therapy (SBRT) in the management of liver metastasis is increasing, using ablative doses with the goal of local control and ultimately improving survival. The aim of this study is to evaluate our initial results regarding local control, overall survival and toxicity in patients with liver metastases treated with this technique, due to the lack of evidence reported in Latin America.

Materials/methods: We performed a retrospective chart review from November 2012 to June 2018 of 24 patients with 32 liver metastases.

Noninvasive stereotactic radioablation for the treatment of atrial fibrillation: First-in-man experience.

Purpose: Catheter ablation is an effective therapy for atrial fibrillation (AF). However, risks remain, and improved efficacy is desired. Stereotactic body radiotherapy (SBRT) is a well-established therapy used to noninvasively treat malignancies and functional disorders with precision.

CyberKnife Stereotactic Radiosurgery in brain metastases: A report from Latin America with literature review.

Background And Aim: Stereotactic radiosurgery is increasingly being employed for the treatment of brain metastases, both as an adjuvant to surgical resection, and also as a primary treatment modality. The aim of this study is to evaluate overall survival and local control in patients with brain metastases treated with CyberKnife Stereotactic Radiosurgery (CKRS), due to the lack of evidence reported in Latin America.

Materials And Methods: We performed a retrospective chart review from October 2011 to January 2017 of 49 patients with 152 brain metastases.

Cyberknife stereotactic radiosurgery and denosumab for giant cell tumour of the skull base: Case report.

Giant cell tumours (GCT) of the skull is a rare entity with only small number of cases reported in literature and optimal treatment is yet to be determined. These tumours have shown high recurrence rates after incomplete surgery, usually occurring during the first year. Even with new surgical techniques a complete resection in skull base tumours is not always possible without functional compromise.

Late Gadolinium Enhancement Cardiac Magnetic Resonance Imaging Post-robotic Radiosurgical Pulmonary Vein Isolation (RRPVI): First Case in the World.

Pulmonary vein isolation using robotic radiosurgery system CyberKnife is a new non-invasive treatment of atrial fibrillation, currently in clinical phase. Robotic radiosurgical pulmonary vein isolation (RRPVI) uses stereotactic, non-invasive (painless) pinpoint radiation energy delivery to a small, precise area to accomplish ablation. The purpose of this report is to describe the finding of an increase in the enhancement of the left atrium demonstrated with the use of cardiac magnetic resonance imaging using late gadolinium enhancement (LGE-CMR) as a result of RRPVI in the first case in the world in humans using CyberKnife as a treatment for paroxysmal atrial fibrillation (PAF).
