Purpose Of Review: This review explores the current landscape of treatments which target the DNA damage response (DDR) in metastatic and muscle-invasive bladder cancer. It emphasizes recent clinical trials which integrate DDR inhibitors with standard chemotherapy and immunotherapy.
Recent Findings: Noteworthy findings include the ATLANTIS trial, which demonstrated prolonged progression-free survival (PFS) in DDR biomarker-selected patients using PARP inhibitors as maintenance after standard chemotherapy. Trials such as BAYOU, which combined immunotherapy with PARP inhibition, similarly suggested a potential therapeutic benefit in DDR biomarker-selected patients with bladder cancer. Efforts to develop bladder-sparing treatment regimens based on DDR-associated mutational profiles, such as the RETAIN and HCRN 16-257 trials, have had mixed outcomes to date. There are now ongoing efforts to combine DDR inhibitors with the newest bladder cancer therapies, such as antibody-drug conjugates. This review highlights the most recent advances in targeting DNA repair deficiency in the evolving treatment landscape of bladder cancer.

Primary clear cell adenocarcinoma (CCA) of the urinary bladder is a rare and aggressive malignancy. Few reports in the literature describe this presentation, as associated with malignant transformation of endometriosis. This case highlights the complex etiology of this variant of CCA, initially diagnosed using comprehensive imaging and genetic analysis, and subsequently confirmed through extensive surgical intervention and chemotherapy.

We report a rare case of urinary bladder neuroendocrine tumour (NET) in a young, non-smoking man. He had no known risk factors and no comorbidities. After being diagnosed with a bladder tumour while being investigated for flank pain and poor renal function, he was treated with transurethral resection of the bladder tumour and deroofing of ureters bilaterally.

Bladder cancer (BLCA) genomic profiling has identified molecular subtypes with distinct clinical characteristics and variable sensitivities to frontline therapy. BLCAs can be categorized into luminal or basal subtypes based on their gene expression. We comprehensively characterized nine human BLCA cell lines (UC3, UC6, UC9, UC13, UC14, T24, SCaBER, RT4V6 and RT112) into molecular subtypes using orthotopic xenograft models.

Purpose: Transurethral resection of bladder tumor (TURBT) is the initial staging procedure for new bladder cancers (BCs). For muscle-invasive bladder cancers (MIBCs), TURBT may delay definitive treatment. We investigated whether definitive treatment can be expedited for MIBC using flexible cystoscopic biopsy and multiparametric magnetic resonance imaging (mpMRI) for initial staging.

Purposes: This study aimed to clarify the clinical outcomes of Bacillus Calmette-Guérin (BCG) treatment in patients with urothelial carcinoma (UC) of the prostatic urethra.
Methods: Between August 2003 and January 2023, 428 patients with non-muscle-invasive UC received BCG treatment (Tokyo strain, 80 mg, ≥ 5 times) in our hospital; 39 had UC of the prostatic urethra. We evaluated the cumulative incidence of intravesical recurrence, progression (muscle-invasive bladder cancer [MIBC] or metastasis), and subsequent radical cystectomy after BCG treatment in patients with UC of the prostatic urethra.
