Pharmacologic Therapies for Non-Muscle Invasive Bladder Cancer: Current and Future Treatments.

Bladder cancer is the sixth most common malignancy in the United States and 70% of cases are non-muscle invasive at the time of diagnosis. Effective treatment is crucial to prevent progression, which occurs in about 30% of patients. The American Urological Association (AUA) guidelines recommend treatment of non-muscle invasive bladder cancer (NMIBC) with intravesical Bacille Calmette-Guerin (BCG) and chemotherapy. However, ongoing shortages and high rates of BCG unresponsiveness creates a major need for novel therapies. In this narrative review, we discuss the evolving landscape of therapeutic options for NMIBC. Pembrolizumab, an anti-programmed cell death (PD)-1 antibody, was the first systemic therapy to be FDA-approved for BCG-unresponsive, high-risk disease. Promising new agents under investigation include various other checkpoint inhibitors and adenovirus-based therapies including CG0070 and nadofaragene firadenovec (rAd-IFNa/Syn3). Finally, new mechanisms of drug delivery are under investigation, including delivery with the GemRIS (TAR-200) device and delivery of intravesical chemotherapy at higher temperatures. With the promise of novel therapies on the horizon, we can expect the role of urologists in the management of NMIBC to evolve and expand.

Impact of inflammatory bowel disease on radical prostatectomy outcomes and costs of care.

BACKGROUND: Recent studies suggest an association between prostate cancer and inflammatory bowel disease (IBD). Our objectives were to investigate clinical and financial impacts of IBD on radical prostatectomy (RP) and to determine the impact of surgical approach on our findings. METHODS: The Premier Hospital Database was queried for patients who underwent RP from 2003 to 2017. Multivariable logistic regression models were used to determine the independent impact of IBD on complications and readmission rates. We determined 90-day readmissions and examined 90-day hospital costs adjusted to 2019 US dollars with multivariable quantile regression models. RESULTS: Our study population included 262,189 men with prostate cancer, including 3,408 (1.3%) with IBD. There were higher odds for any complication for IBD patients compared with non-IBD controls for RP (15.64% vs. 10.66%). Patients with IBD had overall complication rates of 14.1% (P < 0.05) for open surgery and 17.2% for minimally invasive surgery (MIS) (P < 0.01). Between 2013 and 2017, the IBD cohort had significantly more complications (odds ratios (ORs): 2; 95% confidence interval (CI): 1.5 to 2.67; P < 0.0001), was more likely to have surgical costs in the top quartile (OR: 1.6; 95% CI: 1.23 to 2.1; P < 0.01), and had higher readmission rates (OR: 1.51; 95% CI: 1.1 to 2.06; P = 0.01). CONCLUSIONS: The IBD cohort who underwent MIS had the highest complication rates. Hospital readmissions and surgical costs were significantly higher for the IBD cohort who underwent RP between 2013 and 2017, when a minimally invasive approach was more prevalent than an open approach. These findings may be important when deciding which surgical approach to take when performing RP on men with IBD.
