Clinical Innovation Facilitates Treatment of Challenging Condition Using the CyberKnife System
A study evaluated the safety and efficacy of donut-shaped circumferential stereotactic body radiation therapy (SBRT) delivered using the CyberKnife System for the treatment of spinal metastases. This treatment technique is designed to target the spinal column while avoiding the spinal cord. High doses of radiation delivered to the spinal cord can result in serious complications, such as radiation myelopathy, causing injury or paralysis. Study investigators concluded, "Donut-shaped circumferential CyberKnife SBRT is a safe and effective treatment for spinal metastases, achieving high local tumor control with minimal radiation-induced complications, including myelopathy 3."

CyberKnife System Expands Treatment Options for Patients with Painful Neurological Conditions
Trigeminal neuralgia and occipital condyle metastasis are rare conditions often causing excruciating pain that may impact all aspects of patients' daily life.
A study of elderly patients (aged 80 to 100 years) with trigeminal neuralgia found that radiosurgery delivered using the CyberKnife System provides excellent outcomes. Pain improved or disappeared in 90 percent of those evaluated and only three percent developed paresthesia – a sensation of tingling, "pins and needles" or numbness – considered bothersome. Data indicate radiosurgery provides an option for a patient population that may have limited choices because health issues preclude surgery or they are unresponsive to medication4.
An evaluation of SRS for occipital condyle metastasis (OCM) using the CyberKnife System found the treatment offers significant pain relief, excellent local control rates and improvement in neurological symptoms. A 93.8 percent local tumor control rate was achieved over three years. Of patients who reported symptoms, 87.5 percent experienced pain relief. Study authors concluded, "This non-invasive therapy provides a valuable alternative to surgery, potentially enhancing the quality of life for patients with limited treatment options due to this challenging condition5."
