Thank you for your reply. Coincidentally, this morning my spouse was just going over her notes from the first few weeks after my diagnosis and surgery, when I was in a pretty bad place. The oncology team at our Cancer Centre told her that in a case like mine (single metastasis to the spine, though a big enough one to leave me temporarily paraplegic), I could expect 5 to 10 years before organ involvement, and even that might also be easily treatable depending on where the cancer moved. I assume that estimate was based on ADT alone, because we don't have 10 years of data for androgen-receptor inhibitors like Erleada yet, but it might also be an educated guess taking Erleada into account.
