I went to Dr. @ Houston Memorial Hermann to see about this treatment (or one similar upon hearing about it (gold nanoparticles with radiation beads or something to the effect .. he said not ready for prime time -- that was about 2 years ago).
"According to our media partner, the Houston Chronicle back in September 2019, Halas developed what she hopes may be a cure for prostate cancer. It's a treatment method involving nanoparticles, which can be 500 to 10,000 times thinner than a human hair. She invented the particles called "nanoshells "back in 1997, which are coated with a thin layer of gold.
Three years later, she and a colleague found a way to use these particles to attack cancer cells. They founded a company, Nanospectra Biosciences to develop the technology for commercial use. After a year, 13 out of 15 patients it was tested on were cancer-free. Now, as they wait for the FDA's approval, Halas explained why this achievement has a personal meaning for her."
That link seems to lack substance. For example it states, “13 out of 15 patients it was tested on were cancer-free.” , with no indication what type of cancer was involved.
It seems to work in low -intermediate risk localized (in the prostate) prostate cancer. There are not data reported in high risk localized or in metastatic advanced PC. So far this is not a cure for PC, particularly metastatic PC.
Yes this is not as exciting as you may have first thought. There are many cures for localized prostate cancer. The key with this one is it could also cure but with less long term side affects. Unfortunately nothing to indicate any efficacy with stage PC
I remembered the article in 2019 and pulled it up from my saved articles.
This will be potentially another tool with less side effects possibly reducing RP and radiation to the intact prostate as your initial and hopefully final PC treatment, it could also be performed very early to all males perhaps like a vaccine every 5 years, starting very early. Hope it does well.
But they now have to train the nanoshells to find their way to cancer cells where ever they may be in the body. Seems others are working on that idea. I probably have several older articles on that direction.
I had such a article from the nih on light activated nanoshells from like 2017, and actually asked nih in Bethesda Maryland last year if anything had become of it. Not much was petty much their response.
Duke university was performing a trial of one on a patient that raised his own money using another metal (maybe copper) to bind to PC and then tried to heat possibly to kill PC. Never heard anything come of that?
There also was the Israeli use of a seaweed that also killed PC effectively within the prostate. They were going to try to get that approved by the European equivalent a of the FDA a few years ago.
Also in Texas (think it was the U of Texas at Arlington if I remember correctly. It was a process nicknamed the "roach Hotel" it was a "cancer trap" small material applied just under the skin that attracted circulating cancer cells to it and trapped them, then every once in a while you had it removed and inserted a new one. This killed the Circulating Tumor cells to prevent them from landing elsewhere. thereby preventing metastatic spread. That was probably three years ago, crickets since.
I know someone who was working on golf nanoparticles in MDA and later in another hospital. There is no breakthrough as far as I remember. He knows I have PCa and would have advised me to try it if there was any substance in it. I am in regular touch with him.
I wrote to this group and asked whether the treatment could be used for metastatic prostate cancer - they said they didn't think so. What I don't understand is why not? If injected into the body and it seeks out cancer cells in the prostate then why wouldn't it seek them out elsewhere? Or maybe I misunderstood the process.
