JAMA. 2005;294: Background and Rationale Biochemical relapse (prostate-specific antigen [PSA] 0.2 ng/mL) after radical prostatectomy may presage future metastasis Improved risk-assessment models needed for refining patient management Previous cohort analysis evaluated risk of metastasis after rising PSA (n = 304) –Median time from biochemical recurrence to metastasis: 8 years –Median time from metastasis to death: 5 years

JAMA. 2005;294: Main Findings Mean time from surgery to biochemical recurrence: 3.5 years Overall prostate cancer–specific survival from time of biochemical recurrence –5 year: 93% (95% confidence interval [CI]: 90%-96%) –10 year: 73% (95% CI: 66%-79%) –15 year: 55% (95% CI: 41%-67%)

JAMA. 2005;294: Key Conclusions Select clinical variables helpful in establishing prostate cancer – specific mortality risk in patients with biochemical recurrence after radical prostatectomy –PSA doubling time –Gleason score –Time from surgery to biochemical recurrence High-risk patients may consequently be identified for early, more aggressive treatment options
