The primary outcomes were pathological up-staging, defined as the occurrence of extracapsular extension (T3a) or seminal vesicle involvement (T3b), and pathological up-grading, defined as a Gleason sum 7 or higher. Regarding the study design, all data were submitted online by the investigator of participating instutition to the database, which is created specifically for this study within the “Association of Urooncology, Turkey”. RESULTS: Of the 1,212 patients, 981 met study inclusion criteria. Mean PSA level was 6.89 (0.51-15) ng/mL and mean biopsy core number was 12 (8-47). Mean tumor positive cores on final biopsy pathology were 1.95 (1-6) cores [16.6%(2.1-33.3%)]. The RP technique was open, laparoscopic and robotic surgery in 744, 24 and 134, respectively. A total of 368 men (37.5%) underwent pelvic lymph node dissection and only 1 patient (0.2%) had tumor invasion at the final RP pathology. Overall 30.6 % of the men experienced a Gleason sum upgrade and 11.5% had pathological up-staging (figure). A total of 24 men (2.7%) died during follow-up from other causes. A total of 10 patients (1%) underwent radiotherapy with hormonal treatment and had a higher mean PSA level (7.85 vs. 6.89) with higher mean tumor positive core percentage (20.2% vs. 16.6%). A total of 22 patients (2.4%) received only adjuvant radiotherapy and had a higher mean PSA level (7.3 vs. 6.89) but lower mean tumor positive core percentage (15.6% vs. 16.6%). In the remaining 863 patients, who did not received any adjuvant treatment, 26 (3%) experienced PSA failure at a mean time of 35 months (12-88) after the surgery. CONCLUSIONS: In conclusion, up-grading and up-staging at RP is common among Turkish men with low-risk PCa, who are candidates for AS. Most Turkish men with low-risk PCa treated with RP experience long-term PSA control.

METHODS: Criteria for potential AS was defined as: clinical stage T2 or lower, PSA 15 ng/mL or lower, Gleason sum 6 or lower(without 4 as primary or secondary), total biopsy cores 8 or more, 33.3% or lower tumor positive cores on biopsy pathology and with at least 2 years follow-up after RP.
