My Husband was diagnosed 3 years ago with Metastatic PC, GL 9 PSA 310. at 62yrs old.
Started chemo straight away and Lupron shots every 3 months.
His PSA went down to 1.5, but started to steadily climb, Caxodex was added, but that didn't work at all, now hes on Aberitone and prednisone since Dec, and now PSA is going down, thank goodness.
To say it was a shock was an under statement.
My Husband had very few side effects with chemo, hope your other half is the same.
I wish you all the best in his treatment
