Hi Guys, I've had 4 rounds of Docetaxel (Taxotere) and before the last round, I asked the oncologist how we can tell if the chemo is working. She said that we know it's working by my PSA being low and stable (it's at 1.0). I told her that my PSA was low and stable on Zolaedx alone, so how do we know if the chemo's doing anything more. She didn't give me much of an answer, other than to say we might do a PET scan if my PSA starts to rise. Does anyone know what tests I should be asking for to judge the success of otherwise? Thanks Paul.
