Outcome of Robotic Radical Prostatectomy in Men Over 74

Abstract

INTRODUCTION: We set out to evaluate outcomes in patients over 74 after robotic radical prostatectomy. MATERIALS AND METHODS: Six hundred forty-seven patients over 74 (≥75) were analyzed for preoperative factors (body mass index [BMI], American Society of Anestesiologists classification [ASA], prostate-specific antigen [PSA], International prostate symptome score [IPSS], International index of erectile function [IIEF]), operative and perioperative characteristics (technique, erythrocyte conc., complications), and histopathological results. After 12 months, following items were assessed: PSA, frequency of urine loss, number of pads used (including safety), incontinence at night, and potency as quantified by IIEF-5. RESULTS: Mean age in the group <75 was 64.8 years (range 46-74 years) and in the group ≥75 76.9 years (75-88). No statistically significant differences could be detected in terms of BMI, ASA score, or preoperative PSA, respectively. IPSS and IIEF were significantly worse in the group ≥75. Major complications (>Clavien-Dindo III) were found in 1.6% vs. 1.3% (≥75) of cases. Minor complications were encountered in 22.8% vs. 26.3% (≥75). There was a remarkably high percentage of locally advanced disease (73.3% vs. 71.0%) in both groups. Patients ≥75 showed a tendency toward more aggressive cancer and more frequent nodal involvement; we found a higher percentage of R1-resections (19.5% vs. 30.4%, p < 0.05) and PSA relapse after 1 year (12.3% vs. 22.8%, p < 0.05). Twelve months pad-free continence rate (69.9% vs. 63.2%) showed no statistically significant difference between both groups as did the preservation rate of erectile function. CONCLUSION: We could show that robotic prostatectomy can be carried out safely with good functional and histopathological results in patients ≥75. It is therefore questionable if elderly patients can be precluded from curative radical treatment solely because of their age.
