We estimated the incidence of these outcomes among M0-PC patients on ADT and identified prostate-specific antigen (PSA) based biomarkers for mortality and metastasis.METHODS: This population-based cohort study included all nonmetastatic prostate cancer patients in Northern and Central Denmark Regions during 1997-2010, identified through registry data. Primary outcomes were metastasis, overall survival, and bone metastasis-free survival (BMFS). We estimated relative risks (RR) associated with PSA and PSA doubling-time (PSA-DT), measured as time-varying variables beginning at ADT treatment start.RESULTS: We included 2494 M0-PC patients treated with ADT, of whom 1617 (80%) developed CRPC during follow-up. One-fourth of the patients developed metastases within 5 years; bone metastases (BM) accounted for 81% of all metastases. Median survival time was 4.4 years. Compared with PSA <8 ng/mL, PSA ≥8 ng/mL was associated with an adjusted RR of 14.0 (95% confidence interval [CI]: 10.2, 19.0) for BM, 4.4 (CI: 3.9, 5.0) for all-cause mortality, and RR of 4.8 (CI: 4.3, 5.4) for the inverse of BMFS. PSA-DT ≤6 months was associated with an adjusted RR of 7.6 (95% CI: 6.1, 9.5) for BM, RR of 5.9 (CI: 5.2, 6.6) for all-cause mortality, and RR 6.6 (CI: 5.9, 7.4) for the inverse of BMFS.CONCLUSIONS: PSA ≥8 ng/mL and PSA-DT ≤6 months are strong predictors of mortality and bone metastasis.
