Predictive ability of partin tables 2001 in a Welsh population

Area of Science:

• Urology
• Oncology
• Medical Statistics

Background:

• Partin tables are crucial for preoperative counseling in radical prostatectomy for prostate cancer.
• Existing Partin tables are based on a US population, potentially limiting their applicability to other ethnic groups.
• North Wales presents a distinct ethnic demographic compared to the USA.

Purpose of the Study:

• To evaluate the predictive accuracy of Partin tables in a Welsh cohort undergoing radical prostatectomy.
• To determine if Partin tables' predictions for prostate cancer staging are reliable for a non-US population.

Main Methods:

• Retrospective analysis of 177 patients who underwent radical retropubic prostatectomy in North Wales.
• Utilized preoperative clinical staging data for 177 patients.
• Employed Receiver Operating Characteristic (ROC) curve analysis to assess predictive performance.

Main Results:

• The study included 177 patients with localized prostate cancer; 75% had organ-confined disease.
• Partin tables demonstrated strong predictive accuracy: ROC AUC for organ confinement was 0.733, for seminal vesicle invasion 0.738, and for lymph node metastasis 0.780.
• Key pathological findings included 13.5% with extracapsular extension and 9% with seminal vesicle invasion.

Conclusions:

• The predictive performance of Partin tables for prostate cancer staging is applicable to a Welsh population.
• These findings support the continued use of Partin tables for patient counseling and surgical planning in this demographic.
• The study validates the generalizability of Partin tables across different ethnic populations.
