Objective: To investigate the existence of predictive factors for concomitant, primary UUT-UCC and BC. Upper urinary tract urothelial cell carcinoma (UUT-UCC) is a pan-urothelial disease of the transitional epithelial cells. Although several studies have shown the association of bladder recurrence following UUT-UCC, little is known on the incidence of concomitant UUT-UCC and bladder cancer (BC) without previous BC. Materials and methods: A retrospective review of 673 patients diagnosed and treated for UUT-UCC was performed. Patients with history of BC were excluded. We investigated age, sex, location of the upper tract tumor (calyx, renal pelvis, upper ureter, mid-ureter, lower ureter), multifocality, clinical symptoms, tumor grade and pathological stage. Contingency tables and chi-square test were used for categorical variables and analysis of variance (ANOVA) for quantitative variables. Results: 450 patients eligible for inclusion were identified. Of these, 76 (17 %) presented concomitant primary UUT-UCC and BC. Location of primary UUT-UCC was in calyx and/or renal pelvis in 25 patients (34 %), upper ureter 8 (11 %) and lower ureter 37 (49 %). In 6 patients (8 %), data were missing. Concomitant BC was found in 10, 18, and 33 % of patients with primary caliceal/renal pelvis, upper ureter and lower ureter UUT-UCC, respectively. On multivariate analysis, location of UUT-UCC was the only predictive factor for concomitant bladder tumor (OR: 1. 7; 95 % CI, 1. 007-2. 906 p = 0. 047). Conclusions: Our findings suggest that the possibility of concomitant BC in primary diagnosed patient with UUT-UCC is as high as 33 % and mainly depends on upper tract tumor location. © 2012 Springer-Verlag.
