Abstract
OBJECTIVE To assess the relationship between surgical volume (SV), defined as the number of radical prostatectomies (RPs) within a calendar year, and the time to secondary therapy (ST) after RP, as this might represent an important determinant of cancer control. PATIENTS AND METHODS The study included 7937 men treated with RP by 130 urologists between 1989 and 2000. Radiotherapy or any form of hormonal manipulation represented ST. Univariable and multivariable Cox regression analyses was used to evaluate the time to ST after RP. RESULTS SV was an independent (P = 0.02) predictor of ST‐free survival after RP, and the multivariable rate of ST sharply decreased with increasing SV. CONCLUSIONS The use of ST is inversely proportional to SV of up to 24 RPs per year. A higher annual SV might be indicative of less restrictive use of RP in high‐risk patients who eventually require combined treatments.Keywords
