PURPOSE: The Partin tables are a nomogram that is widely used to discriminate @entity263 pathological stages, given common preoperative clinical characteristics. The nomogram is based on @entity1 undergoing radical prostatectomy at The Johns Hopkins Medical Institutions. We validated the Partin tables in a large, population based sample. MATERIALS AND METHODS: The National Cancer Institute Surveillance, Epidemiology and End Results database was used to identify @entity1 treated from 2004 to 2005 who underwent radical prostatectomy. The 2007 Partin tables were used to estimate the prevalence of positive lymph nodes, seminal vesicle invasion, extraprostatic extension and organ confined disease in @entity1 with @entity263 in the database using clinical stage, preoperative @entity1486 and Gleason score. The discriminative ability of the tables was explored by constructing ROC curves. RESULTS: We identified 11,185 @entity1 who underwent radical prostatectomy for @entity263 in 2004 to 2005. The Partin tables discriminated well between @entity1 groups at risk for positive lymph nodes and seminal vesicle invasion (AUC 0.77 and 0.74, respectively). The discrimination of extraprostatic extension and organ confined disease was more limited (AUC 0.62 and 0.68, respectively). The AUC for positive lymph nodes was 0.78 in white @entity1 , 0.73 in black @entity1 and 0.83 in Asian/Pacific Islander @entity1 (p = 0.17). The AUC for positive lymph nodes in @entity1 61 years old or younger was 0.80 vs 0.74 in @entity1 older than 61 years (p = 0.03). CONCLUSIONS: The Partin tables showed excellent discrimination for seminal vesicle invasion and positive lymph nodes. Discrimination of extraprostatic extension and organ confined disease was more limited. The Partin tables performed best in young @entity1 .
