Abstract

OBJECTIVE:

The aims of this study were to establish 15-year postprostatectomy prostate cancer-specific mortality (PCSM), explore the time to prostate-specific antigen (PSA) relapse and identify clinically available prognostic factors.

MATERIAL AND METHODS:

From 1987 to 2004, 309 men (median age 62 years, range 40-74 years) were prostatectomized for localized prostate cancer at a tertiary referral cancer centre. Slightly modified D'Amico risk groups were identified. PSA relapse was defined as PSA ≥ 4 μg/l before 2000, and thereafter as PSA > 0.2 μg/l. Radical prostatectomy (RP) 3-12 months after diagnosis represented "deferred" RP. PCSM was assessed with competing risk modelling. The level of significance was set at p < 0.05.

RESULTS:

After a median of 12 years, 41 men were dead from prostate cancer and 68 due to other causes [15-year PCSM 15%, 95% confidence interval (CI) 10-19%], with no significant difference in PCSM between the low- and intermediate-risk groups, and the "conventional" high-risk group having 24% PCSM (95% CI 16-32%). PCSM was 33% (95% CI 20-46%) for men with two high-risk factors. The median time to PSA relapse (n = 152) was 5 (range 0-17) years, with a median of 7 (range 0-17) years' survival thereafter. Deferral of RP for up to 1 year had no impact on PCSM for all patients combined.

CONCLUSIONS:

Approximately one in seven men with localized prostate cancer, prostatectomized before the PSA era, will die from the disease within the 15 years post-RP. Men with two high-risk criteria have a particularly poor prognosis. After PSA relapse the median survival is 7 years. The data on deferral of RP need confirmation, taking into account risk group allocation.
