I emailed Catalona about this a while ago (if this is the same study), his opinion was these drugs can end up just masking the cancer.
That's exactly what happened to me..My prostate was slightly enlarged but I had no urinary symptoms. After the second clean biopsy, my U-doc said lets try Proscar and see if it brings the PSA down..I said "but I don't have any symptoms".. He replied, that's right, and you don't want any either (speaking of BPH)..We were both delighted when my PSA was cut in half. Little did we know..But when a DRE showed my prostate had shrunk but my PSA had started up again, he insisted on a third biopsy which returned a Gleason 9...Hindsight is always 20-20...
Age today: 68. Married, 6', 215 pounds, active, no health issues.

PSA at age 58: 4.5
PSA at age 61: 5.2
PSA at age 64: 7.5, DRE "Abnormal"
PSA at age 65: 8.5, DRE " normal", biopsy, 12 core, negative...
PSA at age 66 9.0 DRE "normal", BPH, Finesteride. (Proscar)
PSA at age 67 4.5 DRE "normal" second biopsy, negative.
PSA at age 67.5 5.6, DRE "normal" U-doc worried..
PSA at age 68, 7.0, third 12 core biopsy positive for cancer in 4 cores, 3 cores Gleason 6, one core Gleason 9. Finesteride discontinued, still no urinary symptoms, never had any..From age 55 to 65 I had no health insurance.
I have a date with the robo surgeon on Sept 3 but I'm keeping my options
open. I'm also looking at seeds combined with IGRT which seems to be having good results with high-risk patients..
