Smiley: I'm chasing you around, I posted a response under the other thread but I'll do it here also. You mentioned small cell PCa, if that is truly the case MD Anderson is the place to go, its good to hear that you have an appointment there. It also explains the low PSA with multiple metastisis. Small cell is badly differentiated and does not throw off much PSA but it is a really tough strain of PCa. The good news is you're in the best hands possible at MDA.
Try and keep us updated, best of luck to both you and your husband.
