Influence of the facility caseload on the subsequent survival of men with localized prostate cancer undergoing radical prostatectomy.

An in-depth analysis of 488,389 cases of radical prostatectomy performed in more than 1000 facilities over a 10-year period showed better survival when surgery was performed in facilities with more experience and greater caseload. A survival difference of up to 13 months was observed when comparing patients treated at less experienced versus more experienced centers.   Experience across all stages of prostate cancer was a stronger predictor of survival outcome than just the number of surgeries performed.
