Stereotactic Radiosurgery is nothing new in neurosurgery. In fact, Radiosurgery has long been the domain of neurosurgeons (and radiation oncologists) because of its singular usefulness in the treatment of intracranial lesions.
At Las Vegas Cyberknife at Summerlin, we’re innovating how intracranial tumors and AVMs are treated using stereotactic Radiosurgery. During CyberKnife treatment, imaging cameras determine the actual location of the lesion. Each time the robotic arm repositions to deliver another fraction of the ablative dose, CyberKnife recalculates the true position of the target. The result is unsurpassed, submillimeter accuracy. And because there is no need for the stereotactic frame that the Gamma Knife requires, overall treatment time is reduced, anesthesia is unnecessary and the process is painless and comfortable. Also, without the frame, treatment can be delivered in fractions (up to five sessions), if necessary, to spare surrounding healthy tissue.
Yet, CyberKnife goes beyond intracranial lesions. Because highly accurate stereotactic Radiosurgery is achieved without frame, the ability to treat Radiosurgically now includes tumors and lesions of the spine. And at Las Vegas Cyberknife at Summerlin, we use the very latest CyberKnife hardware and software, including the world’s first next-generation linear accelerator. In other words, we have the power to treat more patients with improved accuracy, in less time, and with less patient risk and discomfort than is possible with Gamma Knife.
With Cyberknife, the range of tumors treatable with stereotactic Radiosurgical ablation has increased…and now includes extra-cranial lesions. Here are the clinical indications for which you can choose CyberKnife state-of-the-art treatment….
Astrocytoma, Glioma, Glioblastoma Multiforme, Oligodendroglioma:
Cyberknife offers superior conformance to tumor shape, which is important for
future treatment for recurrence. Cyberknife can also irradiate the tumor bed to
Radiosurgery may be equal to surgery for single metastasis….and better for
multiple metastases. Advanced imaging allows cyberknife to treat those that are
Cyberknife is regularly used to treat spinal metastases. It may also serve as
primary or follow up treatment for meningioma, schwannoma, neurofibroma, hemangioblastoma, chondrosarcoma, chordoma, giant cell tumor, myeloma, lymphoma, osteosarcoma, ewing sarcoma, aneurismal bone cysts and ependymoma.
Cyberknife’s staged treatments may help avoid the risk of visual loss and other side effects associated with single-session radiosurgery. Its superior conformance minimizes irradiation of normal tissue, including the optic chiasm and hypothalamus.
Cyberknife noninvasively ablates the tumor nodule, usually in one session, even in hard-to-reach areas. This is especially beneficial for von hippel linau patients who can become disable by multiple surgeries.
Skull Base Tumors:
The proximity of these tumors to vital nerve and vascular structures makes them surgically problematic. Risk of injury, infection and residual tumor growth make cyberknife a leading treatment.
While chordomas are radio-resistant and close to vital structures, superior conformance and staged sessions permit higher doses and repeat treatments. Cyberknife should be considered as an initial treatment option.
For smaller meningiomas, radiosurgery is an ideal therapy. Cyberknife is especially safe for meningiomas adjacent to critical structures because it can be delivered
Neurofibroma & Schwannoma:
While these tumors’ resistance to radiation makes conventional audiotherapy an option only when surgery is not, cyberknife’s conformance makes it an effective alternative to radiation therapy and surgery for selected patients.
Studies show that cyberknife treatment in stages offers the highest rates ever achieved for hearing and facial-nerve preservation.
Unlike invasive therapies and conventional radiotherapy, cyberknife is painless, frameless, and less risky and therefore more easily repeated to treat recurrence.
With cyberknife, we can treat locations that can’t be safely approached with microsurgery or endovascular therapy. AVMs have an 80% chance of disappearing in a single treatment session. Cyberknife can also be used in conjunction with other therapies to remove remnants.
Cyberknife is the first system to offer radiosurgical treatment of spinal avms... And provides the same accuracy and success as for intracranial AVMs.
