CyberKnife vs HIFU

Prostate Cancer Treatments


HIFU also known as High Intensity Focused Ultrasound and CyberKnife Radiation Therapy are both used to treat prostate cancer and are alternatives to surgery or other types of radiation therapy.


What is CyberKnife Radiosurgery for Prostate Cancer?

CyberKnife RadiationTherapy is used to treat low-risk and intermediate-risk localized prostate cancer and is an alternative to surgery or other types of radiation therapy.

What is CyberKnife Radiation Therapy?                                                                                                                                    

CyberKnife is not a knife at all. It is an innovative radiation therapy technology called Stereotactic Body Radiation Therapy (SBRT). It is used todestroy tumors and lesions throughout the body with pinpoint accuracy, leaving surrounding healthy tissue virtually unaffected. It is fast becoming the treatment of choice for prostate cancer treatment. There is no cutting, incision, blood, anesthesia, pain and requires no recovery time.

CyberKnife uses focused beams of intense radiation to destroy cancer cells and shrink or control the growth of tumors. The objective of radiation therapy is to destroy the harmful cells while minimizing damage to healthy cells. This revolutionary prostate cancer treatment has helped save many lives while maintaining patients’ quality of life.

CyberKnife Radiosurgery is FDA approved and covered by insurance


CyberKnife Treatment for Prostate Cancer

Several effective treatment options exist today for men diagnosed with prostate cancer. Each man’s particular cancer, overall health, age and lifestyle will play an important role in determining which option seems most appropriate. 

During treatment the patient reclines on the CyberKnife bed while the treatment machine moves slowly around you during treatment delivery. You will not feel anything and the CyberKnife does not touch you. You can even listen to your favorite music or just nap.
                                                                                                

The benefits of Radiosurgery with the CyberKnife far outweigh any potential risks, which are minimal. 

CyberKnife treatment is:

▪ Completely non-invasive- Despite its name, there is no knife or cutting involved
 Painless with few to no side effects- You can resume your normal activities immediately following treatment.
▪ Catheter is not needed
▪ NO Anesthesia
▪ Quick- Each treatment typically lasts around 45 minutes
 Precise- CyberKnife uses continuous image-guidance throughout the entire treatment enabling the robot to adjust for any slight movement the patient makes. This enables the CyberKnife beam to follow the prostate’s movement even as the patient breathes normally. If the movement is large the CyberKnife will suspend the beam until the patient is back in alignment. This allows for precise targeting of the prostate in an approximately two to five-millimeter area surrounding the prostate
 Highly successful- The radiation delivered is so precise that the prostate cancer is destroyed
▪ Preservation of sexual function remained the same for most men after treatment. 
▪ An alternative treatment option for certain patients. Individuals who are not candidates for surgery or chemotherapy, or those who have been previously treated with radiation, may be a candidate for CyberKnife.
 Fewer treatments than standard radiation.Thanks to its remarkable clinical accuracy, the CyberKnife treats prostate cancer in 5 treatments over 2 weeks, unlike the low doses of conventional radiation therapy that require 40-45 treatments over the course of 2-3 months. 
▪ Covered by insurance

CyberKnife Radiosurgery is Scientifically Evidence Based 

The most recent ten-year study by Dr. Alan Katz shows that study participants completed their entire treatment in just five daily sessions, compared to conventional radiation therapy which typically takes 30 to 45 sessions.

 Additional 10-year outcomes showed:

▪ The disease-free survival (DFS) rate was 93.7 percent, indicating there were no signs or symptoms of the cancer during the evaluation period;
▪ The median prostate specific antigen (PSA) value was 0.1 ng/ml. A low PSA value is associated with a reduced risk of cancer recurrence or metastases; and 
▪ Patient-reported bowel and urinary function scores showed initial declines which recovered to baseline where they remained throughout the remainder of the study period.

If you are diagnosed with low-risk, localized prostate cancer, CyberKnife Radiosurgery Therapy may be the best treatment option for you. It is safe, easy, covered by insurance, FDA approved and supported by clinical evidence showing that many men are having outstanding success rates a decade and longer after treatment


 

 

 

 

 

 

 

What is HIFU Treatment for Prostate Cancer?

HIFU also known as High Intensity Focused Ultrasound and CyberKnife Radiation Therapy are both used to treat prostate cancer and are alternatives to surgery or other types of radiation therapy. 

 What You Need to Know About HIFU for Prostate Cancer       
                                                           


· Not FDA Approved in U.S. to Treat Prostate Cancer - ONLY FDA Approved for Prostate Tissue Ablation 

· Touted as Non-invasive, however it is Minimally Invasive

· Requires Anesthesia

· Not Covered by Most Insurance Companies

· No Long Term Studies to Determine Safety and Effectiveness

HIFU is NOT FDA approved to treat prostate cancer. The Center for Devices and Radiological Health at the FDA reports that HIFU was approved recently for prostate tissue ablation (to destroy tissue cells of the prostate), it has never been approved in the U.S. to treat prostate cancer. 

How the HIFU Procedure Works 

HIFU is considered a minimally invasive procedure for the treatment of low-risk, localized prostate cancer and for prostate cancer recurrence in the prostate gland. HIFU is an option for men who are not candidates for open surgery (prostatectomy) or don’t want to undergo surgery or radiation therapy.

HIFU uses high-intensity sound waves to heat and destroy cancer cells. It is not indicated for cancer that has spread (metastasized) beyond the prostate.  

Here’s what happens: At the start of the HIFU procedure, a catheter is inserted through the penis into the bladder to catch urine during the procedure and remains in place for 1 to 3 weeks after surgery. 

Then during the procedure an ultrasound probe is inserted into the rectum and directs heated sound waves through the walls of the rectum to destroy cancer cells. With the use of MRI or ultrasound imaging, the sound waves are aimed toward the cancer cells, heating up to temperatures as high as 90 degrees to ablate the targeted cells. 

HIFU is a 3 hour procedure performed under anesthesia with an additional 3 hours in recovery. 
Pain medication and antibiotics are prescribed after surgery and up to 1 week of downtime is required after the procedure.
Potential Side Effects of HIFU Affect Each Man Differently

Potential side effects include:

Erectile dysfunction – Occurs in nearly all cases immediately after surgery. In extreme circumstances, ED can last 18 to 24 months or longer

Urinary incontinence
 – Most men may experience some urine leakage for several weeks following surgery, but the condition typically resolves itself within a few months

Ejaculatory dysfunction - Occurs in all men

Retrograde ejaculation - Develops in 40 to 90 percent of men

Orgasmic issues - Occurs in about 50% of cases

Penis shrinkage - Frequent occurrence that can worsen over time

Nocturnal and morning erections - Men typically lose these erections immediately following surgery, although they do return over time 

Blood or tissue in urine – It is typical to see some blood in your urine while the catheter is in place. You may also see some small pieces of prostate tissue in your urine for at least six to eight weeks following the procedure 

Symptoms include:

· Urinary frequency and burning
· Rectal wall injury from probe
· Rectal incontinence, burning, and bleeding
· Prostate infection

Rectal fistula – Very rarely, HIFU can cause a hole between the rectum and the urethra (the urinary tract). Signs of a possible rectal fistula include:

  • Urine coming out of your rectum
  • Pain in your pelvis or rectum
  • Bowel contents in your urine
  • Air bubbles in your urine

 You’re more likely to get side effects if you have had more than one HIFU treatment or if you’ve had other types of prostate cancer treatments prior to HIFU. HIFU risks are increased each time the procedure is performed.

If you have an enlarged prostate you are not a candidate for this procedure.

HIFU is Often NOT Covered by Insurance 

Medicare covers the actual operational costs of an approved facility where the procedure takes place however the patient is still responsible for the following:
· The time of the physician who performs the HIFU procedure (and the time of any and all associated clinical support staff)
· The time of the anesthesiologist who administers anesthesia 
· Any and all follow-up patient care and support services post-treatment 

FDA’s Report on the Effectiveness and Safety of HIFU Concluded:

• There are “no HIFU effectiveness data relevant to clinical decision-making such as overall survival or prostate-cancer-specific survival in the US.”
• Long-term effectiveness data from outside the US are sparse and outcomes are variable.
• There are “no patient preference data on HIFU treatment in men with prostate cancer.”

When considering HIFU as a treatment strategy for prostate cancer you should seek out a qualified professional who has performed a significant number of the procedures.
