if you can't add to the party.....don't take from it......

CyberKnife to me sounds like you are cutting something. That it is ” robotically” controlled makes me think it may be something like a robotic prostatectomy.  Proton therapy sounds different from radiation therapy. Is it? ProstatRicision sounds to me like something is being cut. “Radiosurgically treating something seems to me that if you use the word “surgical” that there must be some sort of cutting going on. Using a robot to move the laparoscopic instruments to remove a prostate doesn’t seem much different from if a person was holding the laparoscopic instruments. (Whether the robot, the person using the laparoscopic instruments, or for that matter a surgeon using a knife, the prostate is removed and the consequence of that is the same regardless how or what or who takes out the prostate.) What’s a patient to do?

CyberKnife is radiation, to my knowledge there is no knife. A robotic arm guides the radiation treatment. CyberKnife robotic radiosurgery? What?

ProstaRicision is radiation. I don’t know what Ricision means….it sounds like excision, which is what surgery does.

I think protons are what are in radiation…I don’t know but I think it is just another form of radiation. To the proton therapy folks, at least they don’t make it sound like surgery.

The cartoon that I made about ” The robot got my prostate” is a sarcastic spoof about misunderstandings and myths regarding the DaVinci robot.

So……..read, take counsel in your urologist, radiation therapist, friends and family and make a decision that is right for you and for the right reasons. Don’t let the “marketization” of prostate cancer lead you down the wrong path.

In the horse race that is prostate cancer…..based on the above the surgical removal of the prostate by a surgeon utilizing the DaVinci Robot must be in the lead…..otherwise all of the other treatments would not be “implying” that there is surgery involved. And of course always remember….if a doctor, ad, website mentions cure…be wary.

One other thing….all the commercials and brochures have some guy bragging that he is back playing golf  soon after a particular therapy. The rubber meets the road long after the initial treatment of prostate cancer.

 In essence, from a perspective of the long-view, how someone is doing in the first two weeks of therapy is meaningless in the management of prostate cancer.

Oh…..you don’t follow?  You have homework to do.

CyberKnife Treatment For Prostate Cancer

04 Sep 2010

CyberKnife radiosurgery treatment for prostate cancer is rapid, effective and has no side effects, with the added benefit of being non-invasive. Since 2003, the CyberKnife Center of Miami and the CyberKnife Center of Palm Beach have been providing this high tech cancer treatment longer than any facility in South Florida.

Prostate Cancer is diagnosed in more than a quarter of a million men each year in the U.S. Treatment options in existence which are non-invasive with little to no side effects are practically none. CyberKnife treatment for prostate cancer as discussed in this video by James G. Schwade, M.D. executive director and Richard Boxer, M.D. provides an effective treatment overview. The CyberKnife treatment literally kills the cancer cells with a precisely targeted beam of radiation that does not affect surrounding tissue or organs.

CyberKnife Treatment requires:

— No incision

— No blood

— No anesthesia

— No pain

— No recovery or rehabilitation time

According to one prostate patient recently treated Mr. Lane Crosby of Florida, “My friends were all mad that I could go out and play golf and they couldn’t after their prostate cancer treatments.” Crosby was treated in Palm Beach Gardens in 5 treatments at the CyberKnife Center of Palm Beach.

Incorporating a compact, lightweight linear accelerator mounted on a robotic arm, the CyberKnife provides unparalleled flexibility in targeting tumors and lesions. Advanced image guidance technology tracks patient and target position during treatment, ensuring sub millimeter accuracy. The CyberKnife with its Dynamic Tracking Software is cleared by the FDA to provide radiosurgery for lesions anywhere in the body when radiation treatment is indicated. The CyberKnife has often been used to radiosurgically treat otherwise untreatable tumors or inoperable tumors. The system treats tumors at body sites unreachable by other stereotactic systems.

revenge is a dessert best served cold

There were two families that lived next to each other in a  small  neighborhood. One couple  were  Martians and the other  Earthlings. They became good friends over the years and one day over dinner they all  decided it might be interesting  to swap partners for one night.

While being intimate the Martian  man asked the Earthling woman if  everything was going okay. She said  everything was fine. The Martian  man then asked, ” I mean. Is the size suitable to you?”

“Well, the Earthling woman said, it could be a bit longer.”

The Martian man twisted his left ear and amazingly a few extra  inches were added to his ” you know  what.”

The Martian man then  said..” Is that okay now?”

The Earthling woman said , ” That is fine. Can  you make it wider as well?”

The Martian man twisted his right ear and girth  was added.

The next day over breakfast the Earthling man and the Earthling woman were talking.

The Earthling man asked his wife, ” How did it go last  night?”

“Oh, she said, It was fabulous. We  should do that again soon. How did  it go for you?”

The Earthling man said, ” Okay I guess. I don’t know, maybe it’s a Martian thing…but she  would not leave my ears alone. She twisted them all night and they are killing me  this morning.”

The Nanoknife procedure

PDF’s about the machine and company

Nanoknife on dogs….hmmmmmmmmmmmmmmmmm

The following article is from my home town here in Georgia. I bet fifty patients asked me about the procedure over the last few weeks. It was also in an article in the Atlanta Constitution. I had a doctor ask me about it and confessed I had never heard of it. I did know however that there would be no cutting involved. It seems that all the non surgical treatments these days have a catchy name to make it seem like or appear that there is cutting involved. I feel this is in response to the popularity of the robotic prostatectomy and maybe the appearance of surgery comes across more aggressive. In this case nanoknife sounds better than treating a prostate with electricity.

When you read about new treatments and prostate cancer remember this. There is the short-term i.e. getting through the procedure safely. Then there is the long-term i.e. curing the cancer, and avoiding the side effects as they pertain to how you void and sexual function. In the article you see comments about , had the procedure at 7 and home by 2….well that is good. There real story will be at six months and how one does with the trending down of the PSA (i.e. the cancer has been treated) and how things are going with voiding and sex.

As my mother would say, to each his own. My hope that Mr. Taylor does well. All of the energy based treatments will have a role going forward. And each will have a more significant role in the patient that wants to be treated, may have a mild medical issue, and is in his early seventies.

Nothing hurts short-term good results more than long-term follow-up. We will await five-year follow-up on hundreds of patients to see if this new procedure will have a role in prostate cancer. PS…I will look into the process of a urologist getting trained for this as any urologist must have many arrows in his quiver in what he can offer patients that have different medical conditions and wishes regarding how they want to treat their cancer.

Local man undergoes new procedure to treat prostate cancer

Brandee A. Thomas
July 9, 2010

Bob Taylor knows how draining radiation can be on the body.

Each week, he drives patients down to the Veterans Administration clinic in Decatur for radiation therapy.

“It’s usually eight weeks worth of therapy, five days a week. By week five, they are usually pretty dragged out — it really takes a toll on your body,” said Taylor, a 72-year-old Gainesville resident.

So when he was diagnosed with prostate cancer late last year, he knew radiation wasn’t a treatment option he wanted to consider.

“I went to a local urologist, he took 12 biopsies and two came back cancerous. The first thing he did was recommend that I get a second opinion, then he presented the treatment options,” Taylor said.

Those treatment options — prostate removal, radiation or exposing the cancerous cells to extreme temperatures — weren’t what he wanted to consider.

With the help of his wife, Taylor set out to find a more viable alternative. After finding the name of the Atlanta-based Malizia Clinic online, Taylor called to make an appointment for a second opinion. That call ultimately lead to Taylor earning a first-place spot in medical history.

During his consultation at the clinic, Dr. Jaime Wong told Taylor there was an additional treatment option he may be interested in: the NanoKnife IRE System. That option is less invasive than the others, has a shorter recovery period and fewer potential complications.

“I was in the (Atlanta) operating room by around (7:45 a.m.) and was back home by 2 that afternoon,” Taylor said.

“There was no pain and no pain medication.”

The system has been used in around 250 cases worldwide, but Taylor’s surgery was the first time that the procedure has ever been performed on the entire prostate or by a urologist.

The NanoKnife IRE (irreversible electroporation) System uses electricity to kill cancerous cells.

“The (NanoKnife) probes create an electric field that create little defects in the surface of (cancer) cells,” Wong said. “These cells need a solid membrane to live, so this causes them to die.”

Unlike with treatment options like cryoablation , freezing the cancerous portions of the prostate, or radiofrequency ablation — exposing the cancerous cells to extreme heat — the NanoKnife doesn’t cause damage to surrounding tissue, nerves and blood vessels. Thus, it eliminates possible side effects like impotence or incontinence, Wong says.

Because the technology is relatively new, medical professionals are still trying to determine who the best candidates are for the NanoKnife procedure and what its side effects.

“We’re trying to look for better treatment options for this very common disease — it’s the most solid organ cancer in men in the United States,” Wong said.

“More than 200,000 men are diagnosed every year in the U.S., just over 30,000 men die every year from it. There are a lot more men being diagnosed than are dying, so that means we are doing a good job of treating it, but we could always do a better job.”

Since having the surgery three weeks ago, Taylor says he hasn’t had any major problems, especially nothing on par with what others who’ve had more invasive surgery have experienced.

“Several friends have had (other surgical) procedures to treat prostate cancer, so I had something to compare it to. Usually you’re out of service for at least a couple of weeks, but not me,” Taylor said.

Although he’s serving as a guinea pig of sorts, Taylor has taken a “someone has to be first” attitude about it.

“I was a test pilot for a living, so I’m used to doing things that others may not want to,” he said.

“After weighing all of the side effects and other treatment options, I would do it again in a heartbeat.”
