Paul,
I was seeing that it is given in lighter doses for the scan and your other point is well taken. And also my primary point. Additionally there are patients that are betting regular Feraheme scans right now and that will increase toxicity. If this scan leads to unnecessary reaction with radiation we are potentially doing more harm than any benefit. It's kinda the PSA and over treatment discussion all over again but for an advancing disease. In addition, there are other scans available and we do not have evidence yet that using Feraheme works better. There are clinical trials available and that would be the way to consider Feraheme based MRI for patients that have rising PSA after initial treatment if they are so inclined. I still think I would pass on it. I've already been radiated on and we all know for fact the more radiation the more toxicity. And if all we want to do is see if a treatment is shrinking tumors the PSA test is very effective in that way. No scan needed. I know the object here is to see the tumors to treat them as small as they can be. But if one really wants to treat tumors when they are smallest then they should be thinking about
adjuvant therapies on the front end, if possible. That was my logic.
No scan can see a tumor when it's microscopic. We know that's a fact. And it's quite clear that Feraheme is not an agent that can ever do so and we know that's a fact. So while we fuss over hope I personally worry about
false hope, expense, and over treatment ~ not to mention an unnecessary drop in QoL based upon treatment after unproven diagnostics. Even if we prove that Feraheme can see a tumor earlier than other scans, we don't know the survival benefits, if any.
If the clinical trials come back with recognizable false positives then the risks are the patients only and not the proponents touting this stuff. I highly recommend getting second and third opinions before committing to these scans based on what is said in online forums...
Tony
