Hi, we were also surprised. He has done really well on chemo (tolerated 6 cycles with little to no side effects, and PSA down from over 300 pre chemo to 0.4 post chemo). Did so well, that he was told he would have radiotherapy. We were told that the bone mets discovered on CT scans post chemo were not 'new' mets, but instead were highly likely to be pre-existing (non detectable) micro-mets that are now showing up, as have been 'illuminated' by the effects of the chemo. Mets described s tiny and scattered (more than 5 but less than 10). Were told this happens, rarely. Difficult to get our head round this, but it seems Radiotherapy is now off the table, as would do more harm than good. Interested to know if anyone else has experienced this (bone mets only showing up/being illuminated 'after' chemo?). Whether worth pursuing a second opinion on the appropriateness of Radiotherapy?
Will explore this further with Oncologist next week, but expect he will now remain just on hormone therapy / Prostap until it stops working, and then I expect Abi or Enza will be the next option. We will ask also about Xofigo (Radium 223) as I believe this is effective when there are bone mets - however I understand it can now only be administered 'after' chemo and also after Abi or Enza. We will also ask about Apalutamide as a treatment option as my Father is 'metastatic hormone sensitive' and would like to know if Apalutamide has this license. Interested to know others perspectives on the appropriateness of Radium 223 and Apalutamide, given my Fathers position (aged 77, Gleason 9, otherwise fit, PSA was 322 but now 0.4, but bone mets now found). All the best to you
