With stage 4b (remote metastases), we usually stay on ADT and some kind of ARSI forever. I'll be at 4 years this fall, and there are people here in the forum who've been taking it far longer.

In my case, while I don't love the side-effects or Orgovyx + Erleada, my body adjusted to them after a couple of years, and they don't interfere much with enjoying my life now.

It is a tough trade-off. If you go off ADT, there's a risk of your cancer coming back as castrate-resistant; if you stay on ADT, there's elevated risk of heart disease, diabetes, and osteoporosis (among other ailments).

For me, with a history of remote metastasis, the cancer is clearly the bigger threat, so it's an easy choice to stay on; for you, it might be trickier.
