title: Predictive ability of partin tables 2001 in a Welsh population.
abstract: OBJECTIVE
  Partin tables are widely used to select and counsel patients prior to radical surgery for prostate cancer. However, Partin tables have been developed in the USA which has a different ethnic mixture from that of North Wales. We aimed to assess Partin tables' predictive ability in a Welsh population.
  
  
  METHODS
  193 patients underwent radical retropubic prostatectomy for clinically localized carcinoma of the prostate between April 1993 and July 2004 in a single institution in North Wales. Complete preoperative clinical staging information was available in 177 patients. Receiver operating characteristic curve analysis was used.
  
  
  RESULTS
  The mean patient age was 64 (48-73) years. Preoperative clinical staging distribution was: T1c 46.6% and T2 53.4%. 75% had organ-confined disease (TNM 1992). Extracapsular extension without seminal vesicle or lymph node involvement was seen in 13.5%. Nine percent had seminal vesicle invasion without lymph node involvement. Lymph node metastasis was found in 2.2%. The predictive effectiveness of the Partin table was high with an area under ROC curve of 0.733 for organ confinement, 0.738 for seminal vesicle invasion and 0.780 for lymph node involvement (CI 95%).
  
  
  CONCLUSIONS
  Our study demonstrated that the predictive ability of Partin tables for prostate cancer is also applicable to a Welsh population.
