Wow, that's a tough day. ALP of 2500 is pretty high prompting them to sample the bone marrow as this often is an indicator of metastatic or primary bone cancer. I would assume that at the oncology meeting, they will have the results of the testing of that sample and should know what type of cancer they are treating. (whether it's metastatic prostate cancer or primary bone cancer or another form of metastasis) Given the implementation of hormone therapy, it would appear their suspicion is that it is metastatic prostate cancer, or they already have the results and know it is. You didn't mention it, but I would suspect a high PSA? Once they have identified the disease, they will develop and present a treatment and/or palliative care plan. His age and general overall health condition will play a role in that process. More testing such as biopsy or PSMA PET scan may or may not be involved. I would expect that presentation at that oncology appointment.
