Hi Yvie
My OH had 4 cycles of Radium 223, if you click my profile I'm sure the thread I started will come up.
In brief, treatment had to be stopped after 4 as it wasn't doing any good as PSA and Bone Markers rising very quickly, he has now just started Cabazitaxel. He did get a lot of pain with Radium 223 too.
He has had 1 cycle of Cabazitaxel and now 2nd one delayed until next week as he had to have 2 units of blood today. He is also going to be assessed for Olaparib (TOPARP trial) as a potential further option following Cabazitaxel.
He has also had Docetaxel, which didn't work that well and Enzalutamide, which did for 14 months.
Hope this helps, best wishes.
Glen
