Prostate Cancer

CyberKnife treatment for prostate cancer

Prostate cancer can be a life-changing diagnosis for men and their families. Because each patient's condition is different, it is very important to gather all of the information about your condition and the treatment options that are available to you before making a decision.

CyberKnife is the world's first and only robotic radiosurgery system. Although its name suggests scalpels, operating rooms and recovery time, CyberKnife treatment involves no cutting, no pain and no hospital stay. It is a safe alternative to surgery for the treatment of cancerous and non-cancerous tumors anywhere in the body - including the prostate.

You and your doctor will evaluate various treatment options and their advantages and disadvantages to determine the best treatment plan for you.

Choosing a treatment option for localized prostate cancer

Stages of prostate cancer

Patients who have prostate cancer have a "stage" associated with their diagnoses that describes how far the cancer has spread. Different stages of prostate cancer require different treatment approaches. Therefore, staging prostate cancer helps the physician determine the appropriate treatment.

  • Stages I and II (localized prostate cancer): The cancer is still completely contained within the prostate. Stage II is sometimes divided into risk groups (low, intermediate and high) to describe the likelihood of the treatment being able to cure the cancer.
  • Stage III: The cancer has grown beyond the prostate into the surrounding tissue.
  • Stage IV: The cancer has extended to nearby organs or has spread (metastasized) to the lymph nodes or other parts of the body.

There are multiple treatment options for localized prostate cancer (Stages I and II), including cyberknife radiosurgery, active surveillance (watchful waiting), surgery (radical prostatectomy) and/or radiation therapy.

How is CyberKnife different from surgery?

CyberKnife eliminates many of the risks associated with surgery.

How is CyberKnife different from other radiation therapies?

Radiation therapy has been used for decades to treat prostate cancer with varying degrees of success. The goal of any radiation therapy for prostate cancer is to deliver the appropriate dose of radiation needed to treat the cancer, while protecting the surrounding tissues and structures, and minimizing patient discomfort and side effects.

Today, CyberKnife Robotic-assisted Radiosurgery - a robotic radiation therapy that sounds like surgery, but isn't - is offering new hope for patients with localized prostate cancer. It also can be used to treat prostate cancer that has recurred after a radical prostatectomy or previous treatment. CyberKnife has been used to treat prostate cancer for about seven years. Studies are showing CyberKnife treatment produces exceptionally good PSA responses with a low incidence of side effects.

How does CyberKnife work?

CyberKnife, which sounds like surgery - but isn't, uses computerized robotic equipment to deliver beams of high-dose radiation with extreme accuracy and little damage to surrounding tissue.

What is CyberKnife treatment like?

CyberKnife treatment is not like surgery or traditional radiation therapy. You will wear your regular clothes, relax on a cushioned table and listen to music. When it's over, you will resume your normal activities.

What results can I expect?

There is no one treatment result that fits every situation; however, research and experience has shown very positive outcomes.

This graph shows the mean PSA responses over 36 months for 35 low- and intermediate-risk patients treated at Seattle CyberKnife. All patients are free from PSA relapse.

Dr. Robert Meier and the Swedish Radiosurgery Center (previously known as the Seattle CyberKnife Center) lead a national, multi-institutional clinical trial evaluating the efficacy and safety of CyberKnife for low- and intermediate-risk prostate cancer.

Why do patients choose CyberKnife treatment?

No incision. No anesthesia. No hospital stay. No pain. Little or no recovery time.
