@greg2026 So your cancer qualifies as oligometastatic (good), and you're getting doublet therapy (better).

Have they discussed the possibility of metastasis-directed therapy (MDT) instead of chemo, since you have fewer than 5 metastases? Obviously, I don't know your exact situation (and I'm not a medical professional anyway).

Treatments like doublet therapy, triplet therapy, and MDT used to be cutting edge 4–5 years ago, but you should be able to get them at any major cancer facility that's a research centre and/or affiliated with a medical school these days — at least, I'd hope so.

The other increasingly-common approach these days for oligometastatic prostate cancer is to radiate your prostate (aka the "mothership"), even though the cancer has already spread. It's not indicated if there are >5 metastases, however. Another question to ask your medical team.

Best of luck!
