On the stability of Leksell Vantage stereotactic head frame fixation in Gamma Knife radiosurgery: a study based on cone-beam computed tomography imaging and the High Definition Motion Management system.

Objective: The authors' objective was to investigate the stability of the newly introduced Vantage stereotactic frame fixation in single-fraction Gamma Knife radiosurgery.

Methods: A total of 255 patients were included in this work and treated with the Vantage frame and Leksell Gamma Knife (LGK) Icon equipped with cone-beam computed tomography (CBCT) imaging. After the frame was mounted on the patient's head, a CT scan was acquired.

Salvage gamma knife radiosurgery in the management of dysembryoplastic neuroepithelial tumors: Long-term outcome in a single-institution case series.

Background: Dysembryoplastic neuroepithelial tumors (DNT/DNET) are rare epileptogenic tumors. Microsurgery remains the best treatment option, although case reports exist on the use of gamma knife radiosurgery (GKRS) in selected cases. We investigated the long-term outcome of GKRS-treated DNTs at our institution in the context of current diagnostic and treatment options.

Adaptive hypofractionated gamma knife radiosurgery in the acute management of large thymic carcinoma brain metastases.

Background: Brain metastases often lead to serious neurological impairment and life threatening states. Their acute management remains complex, particularly in the case of rare malignancies with aggressive evolution. In large single lesions, open surgery followed by radiation to the surgical cavity is widely regarded as the best approach; yet in many cases, microsurgery is not feasible due to the lesion's critical location and/or the number of brain metastases present.
