Purpose The long-term risk of prostate cancer–specific mortality (PCSM) after radical prostatectomy is poorly defined for patients treated in the era of widespread prostate-specific antigen (PSA) screening. Models that predict the risk of PCSM are needed for patient counseling and clinical trial design. Methods A multi-institutional cohort of 12,677 patients treated with radical prostatectomy between 1987 and 2005 was analyzed for the risk of PCSM. Patient clinical information and treatment outcome was modeled using Fine and Gray competing risk regression analysis to predict PCSM. Results Fifteen-year PCSM and all-cause mortality were 12% and 38%, respectively. The estimated PCSM ranged from 5% to 38% for patients in the lowest and highest quartiles of predicted risk of PSA-defined recurrence, based on a popular nomogram. Biopsy Gleason grade, PSA, and year of surgery were associated with PCSM. A nomogram predicting the 15-year risk of PCSM was developed, and the externally validated concordance index was 0.82. Neither preoperative PSA velocity nor body mass index improved the model's accuracy. Only 4% of contemporary patients had a predicted 15-year PCSM of greater than 5%. Conclusion Few patients will die from prostate cancer within 15 years of radical prostatectomy, despite the presence of adverse clinical features. This favorable prognosis may be related to the effectiveness of radical prostatectomy (with or without secondary therapy) or the low lethality of screen-detected cancers. Given the limited ability to identify contemporary patients at substantially elevated risk of PCSM on the basis of clinical features alone, the need for novel markers specifically associated with the biology of lethal prostate cancer is evident.

Abstract BackgroundTo investigate and validate previously published associations between time to prostate-specific antigen nadir and the time-to-nadir after radical prostatectomy with biochemical recurrence and to extend this analysis to overall survival and prostate cancer-specific mortality risk. MethodsThis is a retrospective analysis of 1796 men from the South Australian Prostate Cancer Clinical Outcomes Collaborative database treated with radical prostatectomy between 1998-2018 with available prostate-specific antigen nadir data within 1-6 months after surgery. Uni- and multivariable analyses of prostate-specific antigen nadir, time-to-nadir, biochemical recurrence and death were performed with Cox and competing risks models (adjusted for age, surgery year, tumour features and preoperative prostate-specific antigen).ResultsThe univariable analysis demonstrated those with shorter time-to-nadir <3 months had a decreased risk of biochemical recurrence (log-rank, p=0.0098) compared to those with longer time-to-nadir 3-6 months. For men with a time-to-nadir <3 months, a Log-rank test showed a decreased risk of prostate cancer-specific mortality (p=0.026) compared to time-to-nadir 3-6 months, without a difference in overall survival. Multivariable competing risk analyses indicated that biochemical recurrence was more likely when time-to-nadir was 3-6 months compared to <3 months (sHR=1.43, CI 1.01-2.02, p=0.04).ConclusionsAmong men undergoing radical prostatectomy, a shorter post-operative time-to-nadir <3 months is associated with decreased risk of biochemical recurrence compared to time-to-nadir 3-6 months. Following adjustment for confounders and competing risks, there was no significant difference in time-to-nadir for mortality outcomes.

5007 Background: Nomograms that predict prostate-specific antigen (PSA) defined biochemical recurrence (BCR) of prostate cancer after radical prostatectomy are the most widely used prediction tools in oncology for treatment decision making and counseling. While BCR universally antedates prostate cancer-specific mortality (PCSM), it is a limited surrogate endpoint due to its variable natural history. Nomograms that accurately predict the risk of PCSM are needed. Methods: Using Fine and Gray competing risk regression analysis, the clinical data and follow-up information of 11,521 patients treated with radical prostatectomy at four academic centers from 1987 to 2005 were modeled to predict PCSM. The model was externally validated on 12,893 patients treated at a separate institution during the same period. Results: The 15-year PCSM and all-cause mortality was 7% and 33%, respectively. The 15-year PCSM for patients with final pathological Gleason score 2–6, 3+4, 4+3, and 8–10 was 1%, 7%, 8%, and 49%, respectively. By pathologic stage, the risks were 2%, 7%, 29%, and 23% for organ-confined, extraprostatic extension, seminal vesicle invasion, and lymph node-positive prostate cancer. Of 3756 patients with organ-confined and Gleason 2–6 cancer, only 1 (0.03%) died from prostate cancer. Primary and secondary Gleason grade (p < 0.001 for both), seminal vesicle invasion (p < 0.001), and year of surgery (p = 0.002) were significant predictors of PCSM. A nomogram predicting 15-year PCSM based on pathologic parameters was accurate and discriminating with an externally-validated concordance index of 0.92. Conclusions: A nomogram has been constructed that predicts the long-term risk of PCSM after radical prostatectomy based on the pathologic grade and stage of the cancer. The presence of poorly differentiated cancer and seminal vesicle invasion are the prime determinants of PCSM. Our study suggests that biomarkers may have limited empiric prognostic utility as PCSM can be accurately predicted once the pathologic features of prostate cancer are known. No significant financial relationships to disclose.

Purpose: To determine whether pretreatment risk groups shown to predict time to prostate cancer–specific mortality (PCSM) after treatment at a single institution retained that ability in a multi-institutional setting. Patients and Methods: From 1988 to 2002, 7,316 patients treated in the United States at 44 institutions with either surgery (n = 4,946) or radiation (n = 2,370) for clinical stage T1c-2, N0 or NX, M0 prostate cancer made up the study cohort. A Cox regression analysis was performed to determine the ability of pretreatment risk groups to predict time to PCSM after treatment. The relative risk (RR) of PCSM and 95% confidence intervals (CIs) were calculated for the intermediate- and high-risk groups relative to the low-risk group. Results: Estimates of non-PCSM 8 years after prostate-specific antigen (PSA) failure were 4% v 15% (surgery versus radiation; Plog rank = .002) compared with 13% v 18% (surgery versus radiation; Plog rank = .35) for patients whose age at the time of PSA failure was less than 70 as compared with ≥ 70 years, respectively. The RR of PCSM after treatment for surgery-managed patients with high- or intermediate-risk disease was 14.2 (95% CI, 5.0 to 23.4; PCox < .0001) and 4.9 (95% CI, 1.7 to 8.1; PCox = .0037), respectively. These values were 14.3 (95% CI, 5.2 to 24.0; PCox < .0001) and 5.6 (95% CI, 2.0 to 9.3; PCox = .0012) for radiation-managed patients. Conclusion: This study provided evidence to support the prediction of time to PCSM after surgery or radiation on the basis of pretreatment risk groups for patients with clinically localized prostate cancer managed during the PSA era.
