Facility-Level Variation in Pelvic Lymphadenectomy During Radical Prostatectomy and Effect on Overall Survival in Men with High-Risk Prostate Cancer

This study was designed to examine facility-level variation in the extent of pelvic lymphadenectomy and to determine whether more extensive lymphadenectomy is associated with a survival benefit among men with localized high-risk prostate cancer. Using data from the National Cancer Data Base, we identified 13,652 men with a high predicted probability of 10-year survival (≤ 65 years of age and Charlson Comorbidity Index score of 0) who underwent...
