Purpose. Kattan and Stephenson nomograms are based on the outcomes of patients with prostate cancer recruited in the USA, but their applicability to Chinese patients is yet to be validated. We aim at studying the predictive accuracy of these nomograms in the Chinese population. Patients and Methods. A total of 408 patients who underwent laparoscopic or open radical resection of prostate from 1995 to 2009 were recruited. The preoperative clinical parameters of these patients were collected, and they were followed up regularly with PSA monitored. Biochemical recurrence was defined as two or more consecutive PSA levels >0.4 ng/mL after radical resection of prostate or secondary cancer treatment. Results. The overall observed 5-year and 10-year biochemical recurrence-free survival rates were 68.3% and 59.8%, which was similar to the predicted values by the Kattan and Stephenson nomograms, respectively. The results of our study achieved a good concordance with both nomograms (Kattan: 5-years, 0.64; Stephenson: 5-years, 0.62, 10-years, 0.71). Conclusions. The incidence of prostate cancer in Hong Kong is increasing together with the patients' awareness of this disease. Despite the fact that Kattan nomograms were derived from the western population, it has been validated in our study to be useful in Chinese patients as well.

characteristics consisted of age, Charlson Comorbidity Index, surgical approach (retropubic vs. robot-assisted vs. laparoscopic vs. perineal), status of lymph node dissection (LND) and nerve-sparing procedure, hospital district, hospital region and hospital volume. We examined the rate of blood transfusion, intra-and postoperative complications, inhospital mortality, length of stay (LOS) and hospital charges using validated methodology.RESULTS: Overall, 25,333 men underwent RP. Of these, 16,372 (64.6%) men were treated by retropubic, 5,657 (22.3%) by robot-assisted, 2,730 (10.8%) by laparoscopic and 574 (2.3%) by perineal RP. The rate of LND and nerve-sparing procedure was 84.1 and 52.8%, respectively. The rate of autologous and allogeneic blood transfusion was 0.3 and 8.8%, respectively. Intraoperative complications were recorded in 2.7%. Specifically, rectal laceration, ureteral injury and nerve-or vessel injury were recorded in 1.5, 0.7 and 1.1%, respectively. Postoperative complications were recorded in 26.7%. Specifically, 2.7% of patients suffered from cardial, 1.1% from respiratory, 4.0% from wound, 1.6% from vascular, 8.6% from genitourinary, 7.5% from miscellaneous medical and 13.2% from miscellanoeous surgical complications. In-hospital mortality was 0.2%. Mean LOS was 10.8 days. Mean hospital charges were 7,409 Euro. Results from multivariable logistic regression analyses will be presented at the congress.CONCLUSIONS: Institutional results should ideally be compared to nationally representative data. In 2012, RP in Germany was performed in 33% in a minimally-invasive fashion, the most temporal overall postoperative complication rate was 27%.
