RESUMO
OBJECTIVE: To investigate the functional and oncologic outcomes of patients with locally advanced or lymph node metastatic prostate cancer (PCa) treated by laparoscopic radical prostatectomy (LRP) in a single Chinese institution. METHODS: From June 2004 to June 2011, a total of 152 cases including 105 locally advanced PCa and 47 lymph node metastatic PCa who were treated by LRP with extended lymph node dissection (ePLND) were enrolled in this study. Surgical records, urinary continence, complications, and oncologic outcomes were presented. RESULTS: The mean operation time and bleeding were 240 min and 110 ml, respectively. After 12-87 months (median 48 m) of follow-up, 91.4 and 94.7 % of the patients were urinary continence at 6 and 12 m, respectively. Eighty biochemical recurrent diseases were observed. The 3- and 5-year biochemical progression-free survival rates were 59.2 and 47.3 %, respectively. Multivariate analysis showed that Gleason score (HR: 1.66, 95 % CI: 1.05-2.64, P = 0.031), pathological stage (HR: 1.64, 95 % CI: 1.2-2.23, P = 0.002), and surgical margin status (HR: 1.75, 95 % CI: 1.04-2.95, P = 0.035) were independent predictive factors for subsequent biochemical relapse. The 3- and 5-year overall and cancer-specific survival rates were 90.2, 86.0 and 95.8, 92.3 %, respectively. There were no significant differences in biochemical recurrence-free (42.6 vs. 49.5 %, P = 0.491), overall (83.4 vs. 87.3 % P = 0.503), and cancer-specific survival rates (92.3 vs. 94.9 %, P = 0.801) between lymph node-positive and -negative PCa. CONCLUSION: With favorable functional and oncologic outcomes in this cohort of 152 patients, we concluded that LRP plus ePLND is feasible for patients with locally advanced non-extra node metastatic PCa.
