Background: The treatment of high-risk non-muscle-invasive bladder cancer (BCa) is problematic given the variable natural history of the disease. Few reports have compared outcomes for primary high-risk tumours with those that develop following previous BCas (relapses). The latter represent a self-selected cohort, having failed previous treatments. Objective: To compare outcomes in patients with primary, progressive, and recurrent high-risk non-muscle-invasive BCa. Design, setting, and participants: We identified all patients with primary and relapsing high-risk BCa tumours at our institution since 1994. Relapses were divided into progressive (previous low-or intermediate-risk disease) and recurrent (previous high-risk disease) cancers. Outcome measurements and statistical analysis: Relationships with outcome analysed using multivariable Cox regression and log-rank analysis. Results and limitations: We identified 699 primary, 110 progressive, and 494 recurrent high-risk BCa tumours in 809 patients (average follow-up: 59 mo [interquartile range: 6-190]). Muscle invasion occurred most commonly in recurrent (23%) tumours, when compared to progressive (20%) and primary (14.6%) cohorts (log rank p < 0.001). Disease-specific mortality (DSM) occurred more frequently in patients with recurrent (25.5%) and progressive (24.6%) tumours compared to primary disease (19.2%; log rank p = 0.006). Other-cause mortality was similar in all groups (log rank p = 0.57), and overall mortality was highest in the progressive cohort (62%) compared with the recurrent (58%) and primary groups (54%; log rank p < 0.001). In multivariable analysis, progression and DSM were predicted by tumour grouping (hazard ratio [HR]: > 1.15; p < 0.026), stage (HR: > 1.30; p < 0.001), and patient age and sex (HR: > 1.03; p < 0.037). Carcinoma in situ was only predictive of outcome in primary tumors. Limitations include retrospective design and limited details regarding bacillus Camille-Guerin use. Conclusions: Patients with relapsing, high-risk, BCa tumors have higher progression, DSM, and overall mortality rates than those with primary cancers. The use of bladder-sparing strategies in these patients should approached cautiously. Carcinoma in situ has little predicative role in relapsing, high-risk, BCa tumors.
