Background: It is not known whether the primary tumour location of upper urinary tract urothelial carcinoma (UUT-UC) is associated with prognosis. Objective: To evaluate the impact of initial primary tumour location on survival in patients who had undergone radical nephroureterectomy (RNU). Design, setting, and participants: Using a multi-institutional, retrospective database, we identified 609 patients with UUT-UC who had undergone RNU between 1995 and 2010. Tumour location was categorised as renal pelvis, ureter, or multifocal. Intervention: All patients had undergone RNU. Measurements: Tumour location was tested as a prognostic factor for survival through univariate and multivariable Cox regression analysis. Results and limitations: Tumour location was renal pelvis in 317 cases (52%), ureter in 185 cases (30%), and multifocal in 107 cases (18%). Compared to renal pelvic and ureteral tumours, multifocal tumours were more likely to be associated with advanced stages (pT3/pT4; 39%, 30%, and 54%, respectively; p < 0.001) and high-grade disease (53%, 56%, and 76%, respectively; p < 0.001). On multivariable analysis, tumour location was an independent prognostic factor for cancer-specific death, disease recurrence, and metastasis (p < 0.05). The 5-yr cancer-specific death-free survival probability was 86.8% for renal pelvic tumours, 68.9% for ureteral tumours, and 56.8% for multifocal tumours (p < 0.001). The retrospective design of this study was its main limitation. Conclusions: Ureteral and multifocal tumours had a worse prognosis than renal pelvic tumours. These findings are not in line with recently published data and should be investigated in a prospective assessment to obtain a definitive statement regarding this matter.
