Key CyberKnife treatment benefits

Ask a physician if CyberKnife treatment is right for you

You deserve the best possible treatment for your brain tumor. Find a physician in your area offering the CyberKnife System — and find out if CyberKnife treatment is right for you.

More than two decades of clinical proof

The revolutionary CyberKnife treatment technology is not new; the CyberKnife System has more than two decades of clinical proof and has helped thousands of patients with various brain tumors and metastases. The CyberKnife System is routinely used to treat conditions in the brain including, but not limited to, benign and malignant primary tumors, brain metastases, trigeminal neuralgia, acoustic neuromas and arteriovenous malformations (AVMs). CyberKnife radiosurgery is even used to treat complicated neurosurgical cases, while maximally sparing healthy brain tissues involved in important functions such as motor control, touching, hearing and vision.

True robotic precision for unrivaled delivery accuracy

The CyberKnife System uses an image-guided linear accelerator mounted on a robot that synchronizes the delivery of radiation with skull motion in real-time throughout treatment.

The CyberKnife Robot

The CyberKnife System uses a robot that will bend and move around you to deliver radiation from virtually any position and any angle. This enables your treatment team to target the tumor or lesion with greater precision.

Real-Time Motion Synchronization

When sub-millimeters matter, even slight patient movements or shifts in the position of the tumor can be significant. The CyberKnife System automatically synchronizes the radiation beam with skull movement in real-time throughout treatment.

Continuous Sub-Millimeter Precision

The robotic delivery and real-time motion synchronization of the CyberKnife System empowers your treatment team to deliver the optimal dose of radiation to the tumor — maximizing treatment effectiveness while minimizing dose to surrounding tissues, which can help reduce the incidence of side effects.

A precise, non-surgical option

The precision of surgical intervention can improve outcomes for many brain tumors, but there are many cases where surgical intervention may not be possible — or simply may not be the best option available. Stereotactic radiosurgery (SRS) with the CyberKnife System can offer a powerful alternative in many cases, delivering surgical-like precision in a non-invasive, typically pain-free treatment that does not require incisions or anesthesia, and is completed on an outpatient basis. CyberKnife multi-session radiosurgery has been shown to enable treatment of tumors close to sensitive structures in the head and neck.1,2,3,4,5 

CyberKnife SRS treatment is frequently used to treat the following types of cases:

Enables re-treatment after previous radiation

In the event of a recurrence, it is generally not possible for patients to undergo a second course of whole-brain radiation. Because the precise targeting of the CyberKnife System significantly reduces irradiation of surrounding healthy tissues, CyberKnife may provide a safe radiation treatment option for some previously irradiated tumors.

CyberKnife® vs. traditional treatments

An effective, less disruptive treatment option

The precision of the CyberKnife System maximizes radiation delivered to the target — while minimizing dose to surrounding healthy tissues. The result is highly effective treatment that eliminates many of the inconveniences of other treatments — and significantly reduces the risk of the side effects that too often disrupt the lives of patients during and after treatment.

CYBERKNIFE VS. SURGERY

The CyberKnife System offers many of the same benefits of precise surgical intervention. But CyberKnife radiosurgery is an outpatient procedure that does not require incisions or general anesthesia. Most patients will not require hospitalization or a long recovery period.

CYBERKNIFE VS. CONVENTIONAL WHOLE-BRAIN RADIATION

Instead of delivering radiation to all brain tissues, CyberKnife radiosurgery targets the tumor(s) with sub-millimeter precision, protecting healthy brain tissues and reducing the risk of common cognitive side effects of whole-brain radiation. In addition, CyberKnife radiosurgery may be completed in as little as 1-5 sessions within 1-2 weeks, compared with 10-15 sessions over 2-3 weeks with conventional whole-brain radiation.

CYBERKNIFE VS. FRAME-BASED GAMMA KNIFE SRS

Compared with single-session radiosurgery with the frame-based Gamma Knife, treatment with the CyberKnife System can be spread out over 1-5 sessions, which may result in fewer side effects1.

Important Safety Statement: Most side effects of radiotherapy, including radiotherapy delivered with Accuray systems, are mild and temporary, often involving fatigue, nausea, and skin irritation. Side effects can be severe, however, leading to pain, alterations in normal body functions (for example, urinary or salivary function), deterioration of quality of life, permanent injury and even death. Side effects can occur during or shortly after radiation treatment or in the months and years following radiation. The nature and severity of side effects depend on many factors, including the size and location of the treated tumor, the treatment technique (for example, the radiation dose), the patient’s general medical condition, to name a few. For more details about the side effects of your radiation therapy, and if treatment with an Accuray product is right for you, ask your doctor.
