Multi centre RCT 1998
3000 men randomised finasteride or placebo for 4 yrs
Aim to examine LT benefit of finasteide in men with symptomatic BPH
What were the findings of the PLESS study?
Reduction in Prostate volume in finastide -18% vs Placebo +14%
Prostate volume reached nadir at 1yr
Symptom score and flow rate in finasteride showed improvement vs placebo
Finasteride - 57% reduciton in risk of AUR
55% reduction in progression to surgery
BAseline PSA predicted disease progression in men (PSA >7ng/ml)
What did the MTOPS study look at?
MTOPS - Medical therapy of Prostate Symptoms
Diuble blind placebo trialed assessing impact of medical therapy on BPH progression
Progression of >4pt rise in IPSS
Development of AUR
Need ofr surgery
INcontinence
Recurrent UTI
renal failure
4.5yr FU
3000 nen - mean vol 36 cc
(Placebo, doxazocin, finasteride, combined doxazocin and finasteride)
Waht did MTOPS find?
Combination therapy provided benefits compared to monotherapy
MTOPS: most important risk factors for clinical progression?
Prostate vol >30 cc
PSA > 1.5
ALSO - identified both treatment and placebo pts with stable PVR had lower risk of AUR than those rising after 4.5 yr FU
ComBAT study findings?
First time that 5ARI superior to alpha blocker in lowering IPSS and QMAx
Combonation superior to monotherapy
