The Cancer Institute at Good Samaritan - Varian Edge® Radiosurgery

Using technology designed for radiosurgical ablation, the Edge® radiosurgery system represents an evolution in the way advanced radiosurgery is delivered. With the Edge system, clinics may be able to treat more patients because of the speed, precision, and streamlined treatment planning developed in its architecture. The Edge radiosurgery system provides a turn-key solution for delivering full-body radiosurgery treatments with accuracy. Edge offers advanced tools designed to deliver highly conformal dose distributions to tumors of the lung, brain, spine, and other areas of the body where radiation is indicated.

A growing body of clinical evidence is demonstrating the benefits of delivering high doses in a small number of fractions1. Starting from classical neurosurgical targets, Stereotactic Radiosurgery (SRS) is progressing to treat targets previously not considered candidates for high-dose, hyprofractionated delivery. The ability to accurately deliver targeted treatments and manage tumor motion is driving growth in radiosurgery. A 108% increase in SRS utilization for brain cancer treatments is predicted over the next 10 years. SRS treatment volume is expected to grow 93% and Stereotactic Body Radiation Therapy (SBRT) volume is expected to grow 144% within the next 10 years. These numbers are suggestive of the high level of confidence that clinicians have in targeting tumors with precision.

One of the key aspects of radiosurgery is precision and accuracy. Edge radiosurgery tracks the patient’s tumor in real time for intracranial and extracranial treatments, precisely calculates patient movement in all six degrees of freedom, and monitors respiratory motion. By integrating the highest dose rate (2400 MU/ minute) with non-ionizing, direct and real-time guidance for target location, Edge offers surgeons and clinicians the ability to pinpoint the target and deliver highly focused treatments, in fewer sessions and at a noticeably fast rate while minimizing the dose received by surrounding healthy tissues.

As an all-in-one, single vendor radiosurgery solution, the Edge system's real-time system architecture helps enable a high level of synchronization between imaging, patient positioning, motion management, beam shaping, and dose delivery technologies. Potentially reducing the overall time and resources required for surgery when compared to traditional methods can lead to an increase in the volume of procedures performed and lower per procedure costs for the hospital. In an effort to advance radiosurgery treatments, clinics worldwide have already adopted Edge to help advance the way cancer is treated.

HyperArc High Definition Radiotherapy

Multuple brain metastases are now frequently treated with stereotactic radiosurgery instead of whole brain radiation therapy. Good Samaritan is the first Institute on Long Island to adopt HyperArc High Definition Radiotherapy. This new technology allows for fully automated robotic treatment delivery to safely, accurately and comfortably treat multiple brain tumors.
