Mel, you're right that her study only showed a 10% survival improvement overall for continuous HT, which did not meet the 20% threshold that the study was designed for. I looked at her subgroup analysis. The survival difference was about
1 1/2 years for those who had minimal disease, but was only 6 months favoring intermittent (not statistically significant) in those who had extensive disease. Based on that subgroup, grandpaof4 will probably have about
the same survival either way.

Intermittent therapy was associated with improved erectile function and mental health at 3 months but not thereafter...At 9 months after randomization, the scores for four of the five quality-of-life outcomes favored intermittent therapy over continuous therapy, but at 15 months, only physical functioning scored higher in the intermittent-therapy group; none of these differences were significant at the prespecified level.
She does mention that there were wide variances in these measures, so individuals may react differently from the average.
I think that for this group T recovery after the "on cycle" gets progressively slower, especially as castration resistance sets in. Perhaps it's also partly due to acclimatization to the new normal.
