Expecting too much too soon?

So sorry to read your latest news - the PSA rising so rapidly while he is apparently still below castrate level suggests that his particular cancer is not reliant on testosterone to survive. You can only wait to hear what the specialist thinks but I would have two questions in mind that I would hope to have some grasp of by the end of the meeting:-
a) was it definitely defined as adenocarcinoma during the diagnosis stage - or could it be one of the more rare types?
b) does the onco believe that it is already castrate-resistant in which case, would a move to enzalutimide or abiraterone be timely?

Sex, bike riding etc would not result in this rapid consistent rise. There is very little data at present on this kind of early use of chemo so there is I suppose still a possibility that the cells are just screaming in objection to the chemo damage they have suffered?
