title: Thirty-day mortality rates and cumulative survival after radical retropubic prostatectomy.
abstract: OBJECTIVE
  To assess the 30-day mortality rate and overall survival after radical retropubic prostatectomy (RRP).
  
  
  METHODS
  Identification of all RRPs performed in the Province of Quebec between January 5, 1988 and January 16, 1996 was accomplished through the Quebec Healthcare Plan Database.
  
  
  RESULTS
  Four thousand nine hundred ninety-seven RRPs were performed by 104 urologists. Overall, 451 deaths were recorded: 32 occurred during the first 30 days (0.6% 30-day mortality rate). A significant decrease in the 30-day mortality rate, from 2.45% to 0.5%, was recorded during the span of the study. The year of surgery, patient age, and hospital type were statistically significant short-term mortality variables (life table analysis). Patient age and year of surgery determined the cumulative survival probability (univariate and multivariate Cox analysis). Cumulative survival at 31 months of follow-up increased from 88.2% in 1988 to 98.1% in 1995. Men 75 years old and older were at a clear disadvantage with regard to survival probability compared with their younger counterparts.
  
  
  CONCLUSIONS
  In this population-based analysis of RRP outcomes, we demonstrated a significant improvement in short- and long-term outcomes, as evidenced by a decrease in the 30-day mortality rate and an improved cumulative survival, recorded over the span of the study. The recorded outcome trends may be explained by improved patient selection and optimal management. Although we are unable to determine cancer-specific outcomes, the results of this analysis should prove valuable to urologists and patients until there are results from randomized trials.
