Radical prostatectomy: survival outcome and correlation to prostate-specific antigen levels.
BACKGROUND
This paper reviews a 10-year experience with radical retropubic prostatectomy (RP) focussing on survival outcome related to pre- and postoperative levels of prostate-specific antigen (PSA).


METHODS
739 patients who underwent RP between 1987 and 1998 were prospectively investigated. Kaplan-Meier analyses were performed and correlated to pre- and postoperative PSA concentrations.


RESULTS
In a follow up period of 11 years duration, (mean 3 yrs.) 57 of 739 patients died (20 from prostate disease progression, 37 from other causes). Correlation between low pre-operative PSA and pathological organ-confinement was significant (p < 0.001). Of 175 patients with PSA progression, 53 (30%) had never reached undetectable levels of PSA. 57% of PSA relapses were detected during the first year, and 3% later than 5 years post-operatively. Kaplan-Meier analysis yielded an average 3 years advantage in estimated prostate-cancer-specific survival when pre-operative PSA levels were below 50 ng/ml. Overall, prostate-cancer-specific and PSA-free 5-year survival-rates were 88%, 96% and 67% respectively.


CONCLUSIONS
Survival-rates after RP are high even in conjunction with unfavourable PSA outcome. Merely one third of deaths resulted from prostate cancer, since men at risk frequently suffer from concomitant diseases that affect survival.
