Abstract

BACKGROUND. Estimates of prostate cancer-specific mortality (PCSM) were determined after radical prostatectomy (RP) or radiation therapy (RT) in men with ≥1 high-risk factors. METHODS. The study cohort comprised 948 men who underwent RP (N = 660) or RT (N = 288) for localized prostate cancer between 1988 and 2004 and had at least 1 of the following high-risk factors: a prostate-specific antigen (PSA) velocity >2 ng/mL/year during the year before diagnosis, a biopsy Gleason score of ≥7, a PSA level of ≥10 ng/mL, or clinical category T2b or high disease. Grays regression was used to evaluate whether the number and type of high-risk factors were associated with time to PCSM. RESULTS. Multiple determinants of high risk were found to be significantly associated with a shorter time to PCSM after RP (P < .001) or RT (P ≤ .001). The solitary presence of a PSA velocity >2 ng/mL/year was associated with an increased risk of PCSM after RP (hazards ratio [HR] of 7.3; 95% confidence interval [95% CI], 1.0-59 [P = .05]) or RT (HR of 12.1; 95% CI, 1.4-105 [P =.02]) when compared with men with any other single high-risk factor. CONCLUSIONS. Men with a PSA velocity >2 ng/mL/year had a significantly higher risk of PCSM compared with men who had any other single high-risk factor. These men should be considered for randomized trials evaluating the impact on PCSM from adding systemic agents to standards of care for men with high-risk PC.
