Purpose: We evaluated whether the risk of progression and the recurrence rate were different in patients with primary and nonprimary stage T1 grade 3 transitional cell carcinoma of the bladder. Materials and Methods: Between 1983 and 1997, 75 patients were treated for stage T1 grade 3 transitional cell carcinoma of the bladder. Of these patients 68 (primary and nonprimary tumor in 58 and 14, respectively) without carcinoma in situ who had not undergone complete cystectomy immediately after diagnosis were included in the study. No maintenance regimen was used. Median followup was 100 months (range 9 to 217). Results: The incidence of multiple tumors in patients with nonprimary tumors was significantly higher than in patients with primary disease (p = 0.035). However, the recurrence-free survival rate in patients with primary T1 GIII bladder tumor was significantly lower than that of patients with nonprimary T1 GIII bladder tumor (p = 0.0016). Multivariate analysis using Cox's proportional hazard regression model revealed that only initial tumor status had statistically significant effects on tumor recurrence (p = 0.007) and no other factors had a significant influence on recurrence-free survival. Progression-free and cancer specific survival rates were also significantly different between the 2 groups (p = 0.036 and 0.0307, respectively). Conclusions: Our study indicates that patients with primary stage T1 grade 3 bladder cancers have higher recurrence and progression potential than those with nonprimary disease despite the higher incidence of multiple tumors in patients with nonprimary tumors.
