Tumors CyberKnife® Treats
Options for benign and malignant conditions
The CyberKnife system offers options for non-invasive radiation therapy for tumors anywhere in the body. The advantages include image-guided technology and flexibility of three-dimensional movement. Among the non-cancerous conditions CyberKnife has been used to treat are:
- Benign tumors such as meningiomas, acoustic neuromas, schwannomas, pituitary adenomas, hemangioblastomas and craniopharyngiomas
- Vascular malformations such as arteriovenous malformations (AVMs), cavernous malformations
- Functional disorders such as trigeminal neuralgia
Cancerous Condition Treatment with CyberKnife
Radiotherapy and radiosurgery have been used for several decades to expand brain cancer treatment beyond surgery and chemotherapy. The advantages of using CyberKnife include the ability to deliver localized, focused radiation treatment. CyberKnife can also be used as a follow up to surgery, without any of the complications or discomfort of conventional radiotherapy methods.
The safety and efficacy of the CyberKnife System for the treatment of malignant cells that have spread from elsewhere in the body to the brain is well established. Published reports indicate high rates of tumor control along with low complication rates for patients with intracranial tumors.
The latest treatment approach for selected spinal cancer involves using highly accurate radiosurgery for lesions anywhere in the spine. This is an improvement upon the previous preferred spinal cancer treatment, which involved surgery (and external beam radiotherapy. Published reports show the following advantages: high rates of tumor control, significant, rapid, and durable pain relief; maintenance or improvement in mental and physical quality of life, and low rates of complications, comparable to intracranial radiosurgery treatments.
For lung cancer patients, CyberKnife offers the unique and significant improvement of its Synchrony Respiratory Tracking System, which automatically tracks and compensates for tumor movement during treatment delivery. Recent studies show promising results.
Early stage prostate cancer can be treated with CyberKnife. Patients undergoing CyberKnife treatment report significantly improved recovery and quality of life during treatment over other more conventional therapies. With CyberKnife there is less risk of side effects such as erectile dysfunction or incontinence.
