I don't believe most patients derive ANY benefit from ADT. Progression-free survival by taking hormones during RT is a myth that some RO's promulgate... It 'may' be beneficial for some high risk patients, with high PSA, but it isn't an 'across the board' benefit for most of us, IMO.
Gary (and others interested) the following snippet from Combining Androgen Deprivation Therapy (ADT) and Salvage Radiation Therapy (SRT) improves outcomes
supports your opinion that ADT is not necessarily appropriate for every patient:(Update 3/21/2019) Fossati et al. identified 3 risk factors that determined optimal duration of adjuvant ADT with salvage RT:
Stage ≥ pT3b
Gleason score ≥ 8
PSA≥ 0.5 ng/ml
Men with 2 or 3 risk factors benefited from up to 3 years of adjuvant ADT; men with 1 of the 3 benefited from up to 12 months of ADT; men with no risk factors did not benefit from adjuvant ADT.
Other recent studies suggest that 18 months ADT is often as effective as three years.
