A retrospective multicenter comparison of conditional cancer-specific survival between laparoscopic and open radical nephroureterectomy in locally advanced upper tract urothelial carcinoma.
<h4>Background</h4>Upper urinary tract urothelial carcinomas are relatively rare and have a cancer-specific survival rate of 20%-30%. The current gold standard treatment for nonmetastatic high-grade urinary tract urothelial carcinoma is radical nephroureterectomy with bladder cuff resect...

| Sumario: | <h4>Background</h4>Upper urinary tract urothelial carcinomas are relatively rare and have a cancer-specific survival rate of 20%-30%. The current gold standard treatment for nonmetastatic high-grade urinary tract urothelial carcinoma is radical nephroureterectomy with bladder cuff resection.<h4>Objective</h4>This study aimed to compare conditional cancer-specific survival between open radical nephroureterectomy and laparoscopic radical nephroureterectomy in patients with nonmetastatic stage pT3-4 or TxN(+) locally advanced urinary tract urothelial carcinoma from five tertiary centers.<h4>Methods</h4>The medical records of 723 patients were retrospectively reviewed. The patients had locally advanced and nodal staged tumors and had undergone open radical nephroureterectomy (n = 388) or laparoscopic radical nephroureterectomy (n = 260) at five tertiary Korean institutions from January 2000 and December 2012. To control for heterogenic baseline differences between the two modalities, propensity score matching and subgroup analysis were conducted. Conditional survival analysis was also conducted to determine survival outcome and to overcome differences in follow-up duration between the groups.<h4>Results</h4>During the median 50.8-month follow up, 255 deaths occurred. In univariate analysis, significant factors affecting cancer-specific survival (e.g., age, history of bladder cancer, American Society of Anesthesiologists score, pathological N stage, and presence of lymphovascular invasion and carcinoma in situ) differed in each subsequent year. The cancer-specific survival between patients treated with open radical nephroureterectomy and laparoscopic radical nephroureterectomy was not different between patients with and without a history of bladder cancer. After adjusting baseline differences between the two groups by using propensity score matching, both groups still had no significant differences in cancer-specific survival.<h4>Conclusion</h4>The two surgical modalities showed no significant differences in the 5-year cancer-specific survival in patients with locally advanced urinary tract urothelial carcinoma. |
