It is mind blowing that mCRPC patients in US don't get Provenge as a initial treatment :(
Other than message board hype, why do you believe this?
Z/X have comparable (if not better) OS stats, and also have response rates which benefits the patient as they are alive.
Z/X do have worse A/E profiles.
These two offset to crate a personal judgement call, and I fail to see why one is always better than the other.
Seriously, do you think the entire medical community is part of the anti-DNDN conspiracy and failing to use Provenge for that reason?
