Abstract [en]

Objective To assess 90-day postoperative mortality after robot-assisted laparoscopic radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP) using nationwide population-based registry data. Patients and Methods We conducted a cohort study using the National Prostate Cancer Register of Sweden, including 22 344 men with localized prostate cancer of clinical stage T1-T3, whose prostate-specific antigen levels were <50 mu g/mL and who had undergone primary radical prostatectomy in the period 1998-2012. Vital status was ascertained through the Total Population Register. The rates for 90-day postoperative mortality were analysed using logistic regression analysis, and comparisons of 90-day mortality with the background population were made using standardized mortality ratios (SMRs). Results Of the 14 820 men who underwent RRP, 29 (0.20%) died, and of the 7 524 men who underwent RARP, 10 (0.13%) died. Mortality in the cohort during the 90-day postoperative period was lower than in an age-matched background population: SMR 0.57 (95% confidence interval [CI] 0.39-0.75). There was no statistically significant difference in 90-day mortality according to surgical method: RARP vs RRP odds ratio (OR) 1.14; 95% CI 0.46-2.81. Postoperative 90-day mortality decreased over time: 2008-2012 vs 1998-2007 OR 0.44; 95% CI 0.21-0.95, mainly because of lower mortality after RARP. Conclusion The 90-day postoperative mortality rates were low after RARP and RRP and there was no statistically significant difference between the methods. Given the long life expectancy among men with low-and intermediate-risk prostate cancer, very low postoperative mortality is a prerequisite for RP, which was fulfilled by both RRP and RARP. The selection of healthy men for RP is highlighted by the lower 90-day mortality after RP compared with the background population.
