First Danish Single-Institution Experience with Radical Prostatectomy : Biochemical Outcome in 1200 Consecutive Patients

Abstract EN

Radical retropubic prostatectomy (RRP) as intended curative therapy for patients with clinically localized prostate cancer (PC) was initiated in 1995 in Denmark.

This paper reports single-institution results from the first 1200 consecutive patients operated during a 15-year period.

Median age at surgery was 63 years.

Median PSA was 9 ng/mL.

Palpable tumors (≤cT2) were present in 48% of patients.

Gleason score at biopsy was ≤7 for 85% of patients.

In sixty-five percent of patients, histopathology revealed localized PCa after RRP.

Positive surgical margins were found in 39.2% of the cases.

Biochemical recurrence (BR) occurred for 214 (18%) of patients.

The estimated biochemical recurrence free survival (BRFS) was 71.7% and 63.2% after 5 and 10 years, respectively.

When patients were stratified according to the D'Amico criteria, BRFS after 10 years was 75.3%, 59.7%, and 39.3% for low-, medium- and high-risk patients, respectively.

In univariate analysis, clinical stage, PSA at diagnosis and type of surgery were significant predictors of BR.

In multivariate analysis, Gleason score > 7, PSA > 10, and higher clinical stage were significant predictors of BR.

Early Danish results in a population not subjected to screening demonstrate BRFS rates comparable with earlier reports from the prescreening era.
