I'm 79 and had stage 4 since 4/2019. After lupron still on and multiple oral rx"s I took achieved non detectable psa for about 4 years. Exhausted all rx's and had chemo for 5weeks. After a month off my psa started rising rapidly and started chemo again. After 3 weeks discontinued chemo and explored pluvicto and have had 2 treatments and will have my third in two weeks. Hopefully psa will decline. Stay tuned for the new results. HappyHag
