Radiosurgery treatments powered by Varian technology are expanding the range of options available to clinicians and patients worldwide. From the Edge and TrueBeam systems for treating tumors in the brain, spine, and other areas of the body as well as non-cancerous, functional conditions like trigeminal neuralgia and essential tremor, to the Eclipse treatment planning system with HyperArc high-resolution radiosurgery, Varian offers versatile and powerful solutions designed to simplify and expedite workflows for planning and delivering these highly conformal radiosurgery treatments.
We are very much looking forward to the first ISRS Congress in the USA since 2007. This will be our first ISRS as part of Siemens Healthineers and our booth will allow interaction with experts from Varian as well as Siemens Healthineers for in-depth software demonstrations on the latest features within the Siemens Healthineers imaging suite as well as Varian’s Eclipse treatment planning system and its HyperArc radiosurgery module.
At this year’s ISRS we’re particularly proud to announce the FDA 510(k) clearance of the Edge and TrueBeam systems for treatment of medically refractory essential tremor with frameless stereotactic radiosurgery.
The Varian Lunch Symposium
Varian’s Edge System: Paving the Way in Functional, Cranial, and Spine Radiosurgery
Varian will host a highly anticipated lunch symposium during ISRS on Tuesday 14th May. The presentations will include an update on the RAD 1601 clinical trial “Edge Radiosurgery for intractable essential tremor and tremor-dominant Parkinson’s Disease” by the principal investigator Dr. Markus Bredel. In addition, neurosurgeons from Memorial Sloan Kettering Cancer Center in New York – Dr. Nelson Moss and Dr. Mark Bilsky – will present on their clinical programs for brain and spine radiosurgery.
The ISRS Scientific Program: Content of Note
A wide range of oral and poster presentations from experienced users of Varian technology from different countries are represented in multiple sessions during the scientific and clinical program. Topics include HyperArc, functional radiosurgery, physics, and SBRT. Highlights among the oral presentations include:
- “Efficacy and safety of frameless virtual cone linac based SRS in refractory tremor” by Dr. Markus Bredel that examines the results of 40 patients treated and demonstrates a marked reduction in tremor severity.
- “Repeated HyperArc Radiosurgery for recurrent intracranial metastases” by Dr. Luca Nicosia who has studied applying HyperArc radiosurgery in case in intracranial progression in order to postpone or avoid WBRT.
- Another noteworthy presentation on HyperArc is that by Dr Whitney Hotsinpiller “HyperArc for benign intracranial tumors: A two-year update”. Her presentation describes results for 183 patients with meningiomas, pituitary adenomas and acoustic neurinomas treated since 2018 and represents the largest registry with the longest follow-up of benign intracranial tumors treated with HyperArc.
- The new enhanced MLC leaf model launched with Eclipse v18 is the subject of Dr. Khayrullo Shoniyozov’s physics presentation “Evaluating the accuracy of an enhanced MLC leaf model for linac-based SRS”. He concludes that the new model substantially improves the efficiency and consistency of the dose calculation algorithm for radiosurgery.
- James Robar presents on Varian’s HyperSight imaging in “Single Breath Hold Cone Beam CT image guidance of SABR” and determines that the faster imaging capabilities improve image quality and allow CBCT imaging in a single breath hold for a variety of SBRT indications.
We look forward to welcoming you to ISRS in New York, seeing you at our lunch symposium, and inviting you to join us for a coffee on our booth!
