I understand “no HT zone” to mean recurrence that can successfully be treated by radiation therapy alone, without the addition of hormone (androgen deprivation) therapy. I.e, you can get a cure without having to suffer through HT.
Statistically, those whose PSA became undetectable before RP failed have better odds that SRT will succeed than those whose post-RP PSA never became undetectable. But in my case it’s a weak indicator because (1) I didn’t stay undetectable very long and (2) my PSA test was sensitive only to .05 no/mL. Had my lab used a more sensitive test, I could be confident my PSA had truly dropped through the floor. As is, my actual nadir may only have been something like 0.47 — well above the 0.03 level that is coming to be accepted as an indicator post-RP that some PCa cells are still chugging along.
I should add that the short doubling time from <0.05 to 0.09 is reason to suspect I never really dropped super low.
