Cryoablation In Clinical Practice

Which Treatment is Better for Unfavorable Intermediate Risk Prostate Cancer, Cyberknife or surgery?

The original indication for cryoablation of the prostate was for salvage therapy in prostate cancer patients who had recurred after either external beam radiotherapy or brachytherapy. However, now prostate cryotherapy is also indicated for primary treatment of prostate cancer. As described in the Prostate Cancer section of this site, Dr. Engel does not feel cryotherapy to be appropriate for all cases of prostate cancer. A typical patient is an older patient, particularly one with voiding symptoms that prohibit the safe application of radiation. Other indications would include lower risk cancers, and in patients with morbidities that would make surgery exceedingly risky.

What Is A Cyberknife

The first thing prostate cancer patients should know about ground-breaking CyberKnife Radiotherapy Treatment, is that it doesnt involve a knife or any surgical procedure. Patients rest on a manoeuvrable seat or table each fifteen seconds their x-rays are taken, as a robotic arm manoeuvres around them, accurately delivering beams of radiotherapy from numerous angles.

Traditionally, radiotherapy treatments allow for a small margin of error this is due to basic inaccuracies or unavoidable movements of the prostate or patient. The CyberKnife vastly reduces this margin of error, bringing it down from between five and fifteen millimetres to just two or less with this high level of precision.

Intensity Modulated Radiation Therapy

IMRT, an advanced form of 3D-CRT therapy, is the most common type of external beam radiation therapy for prostate cancer. It uses a computer-driven machine that moves around the patient as it delivers radiation. Along with shaping the beams and aiming them at the prostate from several angles, the intensity of the beams can be adjusted to limit the doses of radiation reaching nearby normal tissues. This lets doctors deliver an even higher radiation dose to the cancer.

Some newer radiation machines have imaging scanners built into them. This advance, known as image guided radiation therapy , lets the doctor take pictures of the prostate just before giving the radiation to make minor adjustments in aiming. This appears to help deliver the radiation even more precisely and results in fewer side effects.

A variation of IMRT is called volumetric modulated arc therapy . It uses a machine that delivers radiation quickly as it rotates once around the body. This allows each treatment to be given over just a few minutes. Although this can be more convenient for the patient, it hasnt yet been shown to be more effective than regular IMRT.

How Will I Know That The Treatment Has Been Successful

As with any other prostate cancer treatment option, the postoperative PSA blood test will be the primary indicator of a successful treatment. We will obtain a PSA level three months after the procedure, and then every six months for five years. After five years PSA monitoring is generally done annually. We expect to see the PSA come down to a level well below 0.5 ng/dl and remain at the lowest level achieved. Three successive rises in the PSA after reaching the lowest point would raise concern about residual or recurrent prostate cancer.

A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.

While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.

Prostate Cancer Survival By Age

Five-year survival for prostate cancer shows an unusual pattern with age: survival gradually increases from 91% in men aged 15-49 and peaks at 94% in 60-69 year olds survival falls thereafter, reaching its lowest point of 66% in 80-99 year olds patients diagnosed with prostate cancer in England during 2009-2013. The higher survival in men in their sixties is likely to be associated with higher rates of PSA testing in this age group.

Estimating Your Risk of Disease Beyond the Prostate Gland and Treatment AreaProstate cancer treatment requires consideration of disease inside the gland and disease outside the gland. No matter what stage or PSA you have, there is a risk of microscopic disease beyond the gland. The risk of disease beyond the prostate has been extensively studied and reported. Your risk of microscopic disease beyond the prostate can be found in the Partin Tables. Current imaging tools cannot image this microscopic disease and therefore the risk of disease beyond the gland must be estimated from these tables or other sources.

SurgeryThe majority of robotic surgery in this country is done with a nerve sparing technique. This nerve lies within millimeters of the prostate and provides the stimulation for erectile function. Therefore, surgeons, reluctant to make you impotent, often leave these nerves behind. Unfortunately, the studies which have looked at microscopic disease beyond the prostate have shown that disease beyond the prostate is almost always located around these nerves. Therefore, with surgery, which does an excellent job of removing the cancer in the prostate, cancer recurrence is almost always due to the failure to remove this microscopic diseases near the nerves.

How Do You Prepare For Cyberknife

CyberKnife for Prostate Cancer

Youll need to go through a few steps before treatment can begin.

With ultrasound as a guide, a urologist will use long needles to place gold markers in your prostate. This will be similar to when you had your biopsy. CyberKnife will use the markers to track the tumor during treatment.

Then youll need some imaging tests to assess the location, size, and shape of the tumor. This data is sent to the CyberKnife software, so the proper dose, exact location, and number of treatments can be determined.

Your doctor will fill you in on details before you begin so you can plan accordingly.

Youll likely need one to five treatments on consecutive days. This can all be accomplished on an outpatient basis.

Theres no need for anesthesia or other medications, so you can eat and take medications as usual. Avoid lotions and powders on the area to be treated, and wear comfortable clothing. No further preparation is needed.

Sbrt Limits The Field Of Radiation

CyberKnife is a form of stereotactic body radiation therapy , which is a coordinated system to exactly locate the tumor and limit the field of radiation treatment. SBRT delivers a single high dose of radiation or a few fractionized radiation treatments.

There are various types of SBRT, and I believe CyberKnife is the best. CyberKnife utilizes a robotic arm to deliver radiation in different ways and at different angles.

Ever try to slice a grape? It almost seems to squiggle away from the blade, and can result in a poor cut or even a smashed grape. But if you hold that grape against the cutting board between two fingers so it doesnt move, you can slice it precisely the way you want.

The tumor under prostate cancer treatment acts much like the grape: It squiggles away. Thats because the prostate moves unpredictably, caused by air passing through the rectum and by the filling and emptying movements of the bladder, not to mention the patient sneezing or just breathing.

The CyberKnife Robotic Surgery System blends robotics, computer-processing power, advanced imaging and the surgeons skill to make instantaneous corrections in radiation delivery. This is possible despite any movement of the patient or the prostate cancer tumor being targeted.

CyberKnife is a type of external radiotherapy called stereotactic body radiation therapy that directs radiation in very high doses to the exact location of your tumor. Its flexible robotic arm can focus hundreds of laser-like beams of radiotherapy that can be adjusted in diameter and moved at almost any angle for the highest degree of precision. The ability to target only the prostate and not harm the surrounding nerve bundles and organs, such as the rectum and the bladder, is extremely important in maintaining the proper functioning of these vital organs and preventing erectile dysfunction.

One of the primary challenges of treating prostate tumors with radiation is that the prostate gland moves unpredictably throughout the course of treatment. The CyberKnife System continually tracks and automatically corrects for the movement of the prostate and the tumor in real time. This unique capability ensures that radiotherapy continually hits only the intended target without interruption. Four to five tiny slivers of gold are inserted into your prostate to determine the exact location throughout treatments. These help guide the CyberKnife system as your tumor moves.

Risk Factors And Prevention

CyberKnife for Prostate Cancer: Ask Dr. Sean Collins

Risk factors such as age, ethnicity, and family history have been known to influence the chances of a person developing prostate cancer. However, it should be noted that risk factors dont have a direct impact on the development of cancer.

Men over the age of 50 are more likely to develop prostate cancer. In fact, 80% of people who are diagnosed with prostate cancer are over the age of 65.

According to the CDC, African American men are more likely to be at risk for prostate cancer and are more likely to develop aggressive tumors. On the other hand, Caucasian men are just under the average rate of prostate cancer diagnoses. Likewise, Hispanic men also have a lower risk. People of Asian and Pacific Islander descent have the lowest risk of developing prostate cancer.

A family history of prostate cancer can also have an impact on your chances of developing cancer. Only 5% of prostate cancer cases are inherited, but up to 20% of cases are familial, meaning common lifestyle factors and shared genes may have had an influence on the development of cancer.

While risk factors dont have a direct impact on the development of prostate cancer, they can motivate you to monitor your lifestyle more closely. To lower your risk of developing prostate cancer, its recommended to eat a low-fat diet and exercise regularly. However, its best to monitor your health by receiving routine checkups and prostate screenings from your doctor.

Survivability For Prostate Cancer According To Stage

Relative survival looks at a persons chances of surviving after diagnosis compared to a healthy person from the general population who shares similar characteristics, such as age, sex, and race.

For prostate cancer, relative survival depends on the stage of the disease . It is important to note that this prognostic grouping, also established by the UICC, is more accurate than stage grouping in assessing a survival prognostic.
