Prostate Cancer Treatment Advantage

Prostate Cancer

The CyberKnife® Advantage

  • Patient Comfort

    In most cases, radiosurgery with the CyberKnife® System for prostate cancer does not require a catheter. Traditional prostate cancer surgery requires the use of a catheter for help with urination, for up to 2 weeks post-procedure.

    With CyberKnife radiosurgery, the majority of patients can continue normal activity during and immediately following treatment. With traditional prostate cancer surgery patients must limit normal activity for three to five weeks.

    Patients treated with the CyberKnife System for prostate cancer reported a return to normal urinary and bowel function by six months post-procedure.2

    The CyberKnife System delivers the required radiation dose to the prostate with sub-millimeter precision, thereby minimizing the radiation that is delivered to the bowel and urinary tract.

  • Clinically Proven

    In a clinical study of 228 patients treated with CyberKnife radiosurgery for prostate cancer, 75 percent of patients maintained sexual function at the five-year follow-up. The majority of these patients did not require the use of medication.3

    At seven years, a study evaluating 477 men with low- or intermediate-risk cancer found these men experienced a high rate of biochemical progression-free survival (95.6 percent and 89.6 percent for low- and intermediate-risk groups, respectively) with acceptable toxicity and low PSA levels. Biochemical progression-free survival is an indicator that the cancer is neither growing nor spreading.4

    A study of 1,100 men with low- or intermediate-risk cancer showed an overall biochemical progression-free survival of 93 percent at five years. This compares favorably with other definitive treatments for low and intermediate risk patients.5

  • Alternate to Surgery

    Treatments with the CyberKnife System are non-invasive and pain free.

    In some cases, CyberKnife radiosurgery may be an alternative to traditional surgery. It does not typically require anesthesia or an overnight hospital stay, and eliminates the recovery time and risks associated with surgery.

  • Convenient Treatment Schedule

    Treatment with the CyberKnife System is completed in four to five treatment sessions, over the course of a week. Conventional radiation therapy typically requires 30-40 treatment sessions, over the course of several weeks.

  • Retreatment

    Because it can precisely target tumors, the CyberKnife System may provide a safe radiation treatment option even for some previously irradiated patients.

  • Talk to Your Doctor

    Although most patients experience minimal side effects of prostate SBRT, side effects can occur and may be severe. Discuss these with your doctor to determine whether you are a candidate for prostate SBRT with the CyberKnife.
