Provenge is an experimental immunotherapy. Prostate cancer cells have some unique proteins on the surface of the cells. As I understand it, the way Provenge works is that the doctor extracts some of the patient's blood containing his white blood cells, i.e., immune system cells. These cells are then somehow sensitized to prostate cancer proteins (I don't remember how they do that). Then they are cultured, i.e., made to reproduce in a test tube so that there are a lot of them. Finally, they're injected back into the patient where the newly sensitized white blood cells seek out and kill cancer cells. It takes a week's work by highly skilled technicians to do this for one single person and I seem to recall that it costs something like $40,000 per patient, but if it really works I imagine ways will be found to bring the cost way down. This all makes rocket science look easy, but there's some evidence that it works. It's not a cure. The therapy kills some cancer but apparently doesn't get it all. It's still experimental but there is a Phase III clinical trial underway that's apparently getting good results. I have hopes that the technique will continue to be refined and improved until it becomes very effective. It's a promising concept that would have been thought to be wildly impossible just a few decades ago. Ain't science great? Alan Quote Link to comment Share on other sites More sharing options...

It has not been approved, but the company Dendrion made a press announcement that their clinical trial called " impact " for an immunotherapy treatment called Provenge had just matured and it had demonstrated additional survival time for men with advanced prostate cancer. They did not disclose any statistics which will be revealed at the AUA conference at the end of April. The company still must submit their date to the FDA and ask for approval which could easily extend well into 2010. If you are interested in learning more about Provenge you can go to my advanced prostate cancer blog at www.advancedprostatecancer.net I have written extensively about the treatment over the past two years, but the latest information and descriptions about it have been written in the posts of this current week. Malecare- helping men with cancer www.malecare.org www.advancedprostatecancer.net M I haven't heard of it exactly like that. I suspect that Provenge, or some similar therapy, is what Terry had in mind here. Provenge is an experimental immunotherapy.

Then they are cultured, i.e., made to reproduce in a test tube so that there are a lot of them. Finally, they're injected back into the patient where the newly sensitized white blood cells seek out and kill cancer cells. Through a manufactoring process an antigen is attached to the white blood cells that sensitizes them to the pc cells. It takes a week's work by highly skilled technicians to do this for one single person and I seem to recall that it costs something like $40,000 per patient, but if it really works I imagine ways will be found to bring the cost way down. If it is approved nobody knows what the cost will be, the company has been mum on the topic. I will guarentee that it will be expensive. I have seen projected numbers ranging from $45,000 to $125,000, but whi knows. If it is approved it will probably be only approved at this time for men with very advanced disease as they were the subjects for the trial. This all makes rocket science look easy, but there's some evidence that it works. It's not a cure. The therapy kills some cancer but apparently doesn't get it all. As stated, it is NOT a cure. It's still experimental but there is a Phase III clinical trial underway that's apparently getting good results. I have hopes that the technique will continue to be refined and improved until it becomes very effective.
