84 Background: In elderly patients, Charlson score among other features, might allow clinicians to limit the use of aggressive adjuvant treatment strategies or even primary surgical treatment to those who might not achieve benefit during their lifetime. Methods: Retrospective analysis, 7,650 case multicenter high-risk prostate cancer (Pca) radical prostatectomy database selecting >= 70 years old cases. We predicted death from all causes (DAC) and cancer related death (CRD) including all clinical and pathological data. Multivariable analysis were performed to identify independent predictors of DAC and CRD with binary logistic regression, using STATA® software, version 13.1. Results: 2,106 patients from 14 high-volume centers were included. Mean age was 72.8 years (SD 2.46). 206 (9.78%) patients were classified as ASA 3-4 and 497 (23.6%) as CS >=1. Mean PSA was 21.7 ng/ml (SD 50.5). At final histopathology, 800 (38%) had pT3b-T4 disease, GS was 8-10 in 589 (28%), LNI was found in 518 (24.6%) and 822 (39%) PSM. Adjuvant RT, ADT and RT+ADT were administered in 359 (17%), 391 (18.6%) and 437 (20.7%), respectively. Mean follow up was 5.18 years (DS 4.47). BCR occur in 649 (30.8%) and CF in 150 (7.1%) of which distant in 59 (2.8%). Total deaths accounted 341 (16.2%) and CRD for 100 (4.7%) cases. Conclusions: Multicenter data confirms that elderly patients survival harboring high risk prostate cancer will benefit from radical treatment if they are Charlson score 1 or less.
