Background: Men destined to have early biochemical recurrence (BCR) following radical prostatectomy (RP) may be optimal candidates for multimodal treatment. Here we identified pre-operative predictors of early BCR within a surgical cohort who recurred.
Methods: An institutional prostate cancer (PCa) database containing over 20,000 patients was queried to identify 1,471 men who had BCR after RP, and pre-operative predictors of early versus late BCR were assessed. Early BCR was defined as recurrence within 1 year after RP. Within the recurrence cohort, those with National Comprehensive Cancer Network (NCCN) high-risk features were more likely to experience early BCR. Therefore, in all NCCN high-risk men in the database, we abstracted detailed pathologic biopsy data. Among 753 high-risk men, 41 alternate multivariable criteria were assessed for their ability to predict early BCR in crude and adjusted logistic regression models.
Results: The criteria that best identified those likely to experience early BCR are primary Gleason pattern 5 on biopsy or ≥4 cores containing pattern 4 (odds ratio 3.17, P < 0.001). These criteria included 26.7% of NCCN high-risk men. Additionally, these criteria selected for men within the high-risk classification who were at significantly higher risk of subsequent metastasis (adjusted hazard ratio 3.04, P < 0.001) and cancer-specific death (adjusted hazard ratio 3.27, P < 0.001).
Conclusions: In men with PCa who present with high-risk features, pre-operative criteria have the ability to discriminate the subgroup most likely to experience early BCR after RP. Men at risk for early disease recurrence may be the most suitable candidates for multimodal therapy.
