Response of Patients on Surveillance for Prostate Cancer to Dutasteride
Hypothesis: That, in men on surveillance for favorable risk prostate cancer treated with dutasteride, prostate specific antigen (PSA) kinetics is of value in identifying those men who harbor occult high grade prostate cancer.
The study will determine the prevalence of a secondary rise in PSA > 0.5 ng/ml and the PSA doubling time in subjects on surveillance being treated with dutasteride.
|Study Design:||Observational Model: Cohort
Time Perspective: Retrospective
|Official Title:||Assessment of Response of Patients on Surveillance for Favorable Risk Prostate Cancer to Dutasteride|
- change in serum PSA [ Time Frame: change from baseline in serum PSA up to secondary rise in serum PSA > 0.5, up to 6 months ] [ Designated as safety issue: No ]The time that the change in serum PSA from baseline to the secondary rise will be used to determine the PSA 'kinetics' in men on surveillance for prostate cancer.
- rate of secondary rise in serum PSA [ Time Frame: at 6 months after starting dutasteride therapy ] [ Designated as safety issue: No ]Rate of rise in sereum PSA will be correlated with prostate gland volume at initial biopsy.
