The US Food and Drug Administration recently defined the clinical term "bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer" as a disease state resistant to adequate bacillus Calmette-Guérin therapy. There is a significant lack of prognostication for this disease even in patients who have undergone early radical cystectomy. This study aimed to identify the clinical outcomes and prognostic factors in Japanese patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer who underwent early radical cystectomy.Data from a large-scale multicenter retrospective study included 2879 patients with highest-risk or high-risk non-muscle-invasive bladder cancer who received intravesical bacillus Calmette-Guérin induction therapy between January 2000 and December 2019. A total of 141 patients (4.3%) met the criteria for bacillus Calmette-Guérin-unresponsive disease, of whom 47 (33.3%) underwent early radical cystectomy. Prognostic factors for three clinical endpoints, namely, unresectable lesion-free survival, cancer-specific survival, and overall survival, were identified.The highest-risk status at induction bacillus Calmette-Guérin was associated with short unresectable lesion-free survival (hazard ratio 7.85; P 0.05), cancer-specific survival (hazard ratio 12.24; P 0.05), and overall survival (hazard ratio 9.25; P 0.01). Moreover, extravesical tumors (pathological T3 or T4) on the radical cystectomy specimens were associated with poor prognosis and were found at a higher rate in patients with the highest-risk status at induction bacillus Calmette-Guérin than in those with high-risk status (35.7% vs 21.2%).The highest-risk status among the pre-bacillus Calmette-Guérin factors was associated with upstaging to extravesical tumors and poor prognosis despite early radical cystectomy procedures. Appropriate decision-making and the correct timing of radical cystectomy are vital to avoid treatment delays and improve outcomes.

OBJECTIVE To assess the feasibility and functional/oncological outcomes of selective tetramodal bladder-preservation therapy in elderly patients with muscle-invasive bladder cancer. METHODS This study analyzed 154 patients with non-metastatic muscle-invasive bladder cancer who were enrolled into the protocol. After maximal transurethral resection and induction chemoradiotherapy, patients with clinical complete response were offered consolidative partial cystectomy to achieve bladder preservation; otherwise, radical cystectomy was recommended. Postoperative complications, preserved bladder function, and oncological outcomes were compared between elderly (aged ≥75 years) and younger patients (aged
