At 65y with a 7(4+3), I had 28 sessions of proton radiation (during April-May 2021), plus Casodex (Bicalutimide), 6 months (two 3-month injections) of Eligard, and SpaceOAR Vue.

Proton radiation treatments were relatively uneventful.

PSA was a (Finasteride-adjusted) 7.976 ng/mL prior to treatment, dropped as low as < 0.008 during treatment (due to the Eligard; testosterone dropped to 3.0 ng/dL. Since radiation treatment and Eligard ended, PSA now varies between 0.3-0.5 ng/mL, with the most recent PSA being 0.43 ng/mL.

So far, there’s no evidence of disease. Hope your outcome is as successful.
