A substantial proportion of patients with intermediate- and high-risk disease will progress to invasive bladder cancer and are at a significant risk for metastasis and death. Bacillus Calmette-Guerin (BCG) therapy for selected cases has been the standard of care for nearly 40 years. Unfortunately, a world-wide shortage has made BCG challenging to obtain. Furthermore, recurrences and progressions do occur. With the US Food and Drug Administration creating a clear path to drug approval for novel treatments, many therapies have been tested, including intravesical cytotoxic chemotherapy, intravesical immunotherapy, systemic immunotherapy, and novel agents, such as gene therapy and targeted therapy. In this review, we highlight ongoing clinical trials.

Volume 22, Number 2Review ArticlesNon–muscle-invasive Bladder Cancer: Overview and Contemporary Treatment Landscape of Neoadjuvant Chemoablative TherapiesTreatment UpdateRichard S MatulewiczGary D SteinbergNon–muscle-invasive bladder cancer (NMIBC) is a heterogeneous subclassification of urothelial carcinoma with significant variation in individual risk of recurrence and progression to muscle-invasive disease. Risk stratification by American Urological Association (AUA) and European Association of Urology (EAU) guidelines or by using nomograms/risk calculators developed from clinical trial data can help inform patient treatment decisions but may not accurately classify all patients. Risk-adapted adjuvant (post–transurethral resection of bladder tumor [TURBT]) treatment strategies using intravesical therapies are an important means of balancing disease control with potential adverse effects. Adjuvant intravesical instillation with various chemotherapy agents and bacillus Calmette-Guérin (BCG) is well studied and associated with excellent outcomes for most patients. However, upwards of 40% of patients recur within 2 years and roughly 10% progress to muscle-invasive bladder cancer. Novel approaches and agents that aim to reduce the treatment burden associated with NMIBC are increasingly needed. We review the current landscape of NMIBC as it pertains to the use of and rationale for emerging neoadjuvant chemoablative therapies.
