Stupid question from a rookie (aside from costs, etc...):
Provenge takes immune cells out of a patient's blood, alters them, and infuses them back in. It appears that it is currently used for patients where HT is no longer effective. You would think that a patient's immune system would be better earlier in the battle.
Could it be possible to use blood drawn from year's past? And, can you even store blood that long? Point being, that perhaps this would increase the survival periods. Think about it, we could give blood and if we needed it down the road, it would be there.
I'm sure this is completely flawed....and I'm done now playing mad scientist.
