A non-invasive, non-surgical option with proven results

The CyberKnife System is a non-invasive, non-surgical, pain-free treatment option for prostate cancer with proven results. It is the first and only radiotherapy device that brings true robotic precision and the ability to track, detect and correct for tumor motion in real-time, to the treatment of cancer. These capabilities enable your medical team to deliver radiation with sub-millimeter accuracy, helping to minimize the risk of side effects and preserve your quality of life during and after treatment. The CyberKnife technology is not new; the system has more than a decade of clinical evidence and has helped thousands of men with prostate cancer.

Read the Clinical Proof

More than two decades of clinical proof

The CyberKnife is commonly used for treating low- to intermediate-risk prostate cancer and is the only radiotherapy device supported by years of published clinical follow-up with a large number of patients.

SAFE AND EFFECTIVE

Prospective, multi-institutional study data supports the safety and efficacy of CyberKnife for men with low- and intermediate-risk prostate cancer.1, 2

EXCELLENT LONG-TERM OUTCOMES

Clinical studies report CyberKnife provides excellent long-term disease control for prostate patients.3, 4, 5, 6, 7, 8, 9

20,000+ PROSTATE CANCER TREATMENTS

More than 20,000 men have been treated with CyberKnife.

The prostate moves. The CyberKnife System adapts and synchronizes treatment delivery with the motion in real time.

The prostate gland can move unpredictably throughout the course of treatment — as much as half an inch in as little as 30 seconds because of normal patient bodily functions (filling of the bladder, gas in the bowel, or even slight patient movement).1 Unlike any other radiation treatment, the CyberKnife System continually tracks the target, automatically adapts and synchronizes the radiation beam with movement of the prostate in real-time throughout the entire treatment session. This helps to ensure the radiation dose is delivered to the target — maximizing treatment effectiveness while protecting surrounding tissues to reduce the incidence of side effects.

Sub-millimeter robotic precision

The CyberKnife robot, guided by motion synchronization software, can deliver radiation from virtually any angle — allowing it to maintain sub-millimeter accuracy throughout treatment delivery. Greater precision helps minimize dose to surrounding healthy tissues, reducing the risk of many common side effects.1, 2, 3, 4

Enables re-treatment after previous radiation

Because the precise targeting of the CyberKnife System significantly reduces irradiation of surrounding healthy tissues, CyberKnife can be a powerful treatment option for a wider range of prostate cancer patients:

  • CyberKnife may provide a safe radiation treatment option even for patients who have previously received radiation therapy.
  • Patients treated with CyberKnife are excellent candidates for re-treatment, in the event of recurrence.
  • Patients treated with CyberKnife may still be candidates for surgical interventions, in the event of recurrence.

CyberKnife® vs. traditional treatments

An effective, less disruptive
re-treatment option

The unparalleled precision and motion synchronization capabilities of the CyberKnife System maximize radiation delivered to the target — while helping to safeguard 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

CyberKnife treatment 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. BRACHYTHERAPY

CyberKnife treatment eliminates the inconvenience and risk associated with radioactive seed or catheter implants.

CYBERKNIFE VS. CONVENTIONAL RADIATION THERAPY

CyberKnife treatment is completed in as little as 4-5 sessions over 1-2 weeks, compared to 30-40 sessions over 8-10 weeks with conventional radiation therapy.

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.
