Introduction The aim of this study was to assess the association between the type and number of D'Amico high-risk criteria (DHRCs) with rates of pathologically non-organ-confined (NOC) prostate cancer in patients treated with radical prostatectomy (RP) and pelvic lymphadenectomy (PLND). Material and methods In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 12961 RP and PLDN patients with at least one DHRC. We relied on descriptive statistics and multivariable logistic regression models. Results Of 12 961 patients, 6135 (47%) exclusively harboured biopsy Gleason score (GS) 8-10, 3526 (27%) had clinical stage >_T2c, and 1234 (9.5%) had prostate-specific antigen (PSA) >20 ng/mL. Only 1886 (15%) harboured any combination of 2 DHRCs. Finally, all 3 DHRCs were present in 180 (1.4%) patients. NOC rates increased from 32% for clinical T stage >_T2c to 49% for either GS 8-10 only or PSA >20 ng/mL only and to 66-68% for any combination of 2 DHRCs, and to 84% for respectively all 3 DHRCs, which resulted in a multivariable logistic regression OR of 1.00, 2.01 (95% CI 1.85-2.19; p <0.001), 4.16 (95% CI 3.69-4.68; p <0.001), and 10.83 (95% CI 7.35-16.52; p <0.001), respectively. Conclusions Our study indicates a stimulus-response effect according to the type and number of DHRCs. Hence, a formal risk-stratification within high-risk prostate cancer patients should be considered in clinical decision-making.
