Popis: To analyze the biologic behavior and etiologic mechanism of upper-tract involvement in patients with bladder cancer in situ (Tis) and its impact on management of these patients.One hundred thirty-eight patients with bladder Tis, 786 with superficial bladder cancer, and 179 patients with invasive bladder cancer treated by cystectomy were studied: 34 (24.6%), 18 (2.3%), and 7 (3.9%) developed upper-tract involvement in each group, respectively. Sixty-three patients with primary urothelial upper-tract tumors were also studied. Taking progression-free survival as an end point, univariate and multivariate analyses were performed.The upper-tract recurrence rate was significantly higher in patients with bladder Tis than in patients with superficial bladder tumors (P0.001); it was also significantly higher in patients treated with cystectomy because of bladder Tis compared with those treated because of invasive tumors (P0.01). Patients with bladder Tis and upper-tract involvement showed high rates of upper-tract bilaterality (32.3%) and prostate involvement (67.4%). On pathologic examination, the upper tract showed predominantly superficial (Ta-T1-Tis) tumors (67.4%) and distal ureter location as the only finding (47%). In patients with bladder Tis, upper-tract involvement alone does not have a negative impact on the survival rate according to univariate and multivariate analysis (P = NS).In patients with bladder Tis, upper-tract involvement represents a diffuse process; therefore, a close evaluation of both the prostate and the upper tract is recommended. Upper-tract involvement has no impact on bladder-preservation strategy. Many of these patients could also be offered a conservative management for the involved upper tract.
