I had an enquiry off my site for more information on Laser Hyperthermia treatment by a newly diagnosed man who said he was surprised that none of the men who contributed their stories to the site had taken advantage of this ‘new and excellent' therapy. He quoted two sources for his information.

The first was this piece Mayo Clinic Finds Early Success with Laser that Destroys Tumors with Heat

I was somewhat bemused to read there

In the United States, laser ablation is primarily used to treat brain, spine and prostate tumors, but is cleared by the U.S. Food and Drug Administration (FDA) for any soft tissue tumor. Only a few centers have adapted the technique to tumors outside of the brain.

I have personally never heard of prostate cancer being treated with laser ablation perhaps that is because, as the pieces says “…..few centers have adapted the technique to tumors outside of the brain.” That raises the question in my mind – WHY? If the technique is so good, why on earth do more centers not use it? Hmmm….maybe it isn’t that good? I also felt that the reference to FDA approval should be seen in the context of how such approvals can be granted. In this case, as the media release says it has been <" …. cleared by the U.S. Food and Drug Administration (FDA) for any soft tissue tumor" This does NOT necessarily mean that there have been any specific studies for efficacy with prostate cancer.

Then this statement also made me think:

At the March meeting of the Society of Interventional Radiology, Dr. Woodrum, presented results from the first known cases of using MRI-guided laser ablation to treat prostate tumors. He said then that the safe completion of four clinical cases using the technique to treat prostate cancer in patients who had failed surgery “demonstrates this technology’s potential.”

Apart from the point that this presentation in March 2010 related to what were said to be first known cases of PCa treatment, which seemed to clash with the statement that laser ablation is primarily used to treat prostate tumors in the USA, my main question was - if the men had failed surgery, into just what part of their anatomy were the laser probes inserted?

The other site to which he referred was that of at Valley Cancer Institute. I know nothing about this organisation but was singulalrly unimpressed by their site and in particular the page that dealt with Hyperthermia, one of the most effective and low or no side effects cancer treatment available worldwide!

I’m always a bit surprised when a ‘new’ therapy pops up – has anyone else heard of this one – and does anyone have any comments?

It is a tragedy of the world that no one knows what he doesn’t know, and the less a man knows, the more sure he is that he knows everything. Joyce Carey

Below is a link where my doctor used a laser for Targeted Focal Treatment.

Ziggy,

Thanks for posting. It is interesting to read about additional treatments. Who knows, in 5-10 years, this may be a mainstream treatment.

Even though the article in the newsletter was not meant for PCa veterans like us, it would have been nice if the article included info about whether the treatment was successful in eliminating the cancer (even in non-clinical terms). The article focused just on how innovative the procedure was and not on its success or failure.

The procedure using cryosurgery has been successful in my case. So I can easily vouch for that. In fact I'm to see him again in Feb - Mar for another semi annual PSA and if it remains at around the last which was .32 I move to annual psa check ups. It will be 3 years after TFT then. A clinical trial that has be an undeniable success. Only effects is maybe a 60% reduction in ejaculate. I've never had a day of incontinence, and my catheter time was one day after the saturation biopsy and 4 days after my TFT total.

I have heard of Radio-Frequency Ablation.. being used to treat cancer - generally.

Consider the Prostate and it's self contained Service Duct..

How easy would it be to make a miniature antenna and deliver it via catheter to inside the Prostate and FIRE..

Would that be high-intensity focused ultrasound (HIFU) ?
