Bladder Cancer

A simple blood test, much like that used to detect tuberculosis, might identify as many as half of bladder cancer patients likely to fail intravesical bacillus Calmette-Guérin immunotherapy.

Findings of a multi-institutional cohort study provide further evidence that favorable outcomes can be achieved by carefully selected patients with muscle-invasive bladder cancer who forgo radical cystectomy after achieving a clinical complete response to neoadjuvant chemotherapy.

Even though patients with muscle-invasive bladder cancer and significant comorbidity are likely to benefit from bladder-sparing treatment approaches, increasing comorbidity burden appears to have no correlation with receiving such treatments.

“I think this study indicates that this is a procedure that not only improves detection, but also has a high rate of perceived value for patients, and therefore would be worthwhile to use in practice,” says researcher Angela B. Smith, MD.

“We believe that our study underscores the importance of improving dissemination of the guidelines and their implementation and uptake in practice,” says researcher Nikhil Waingankar, MD, MSHP.

The investigational oncolytic immunotherapy CG0070 produced an overall 30% complete response rate at 12 months for patients with high-risk BCG-unresponsive non-muscle-invasive bladder cancer.

Despite improved patient awareness and established guidelines, compliance remains low.

In this video, Trinity J. Bivalacqua, MD, PhD, presents the case of a 63-year-old man with history of carcinoma in situ found to have low-grade Ta non-muscle invasive bladder cancer.

Fluorescent blue light cystoscopy improves 3-year recurrence-free survival rates in patients with recurrent bladder tumors compared to white light cystoscopy, and researchers believe its use should be expanded.

"Numerous clinical studies have exhibited significantly improved tumor detection rates with BLC," write Zachary L. Smith, MD, and Norm D. Smith, MD.

A look at Urology Times' most-read articles on bladder cancer reveals a variety of topics, ranging from radical cystectomy to the role of protein- and cell-based urinary biomarkers for bladder cancer detection and surveillance.

The use of intravesical cisplatin nanoparticles reduces cancer cell proliferation while limiting drug absorption beyond the bladder barrier, according to early findings.

Researchers from The Cancer Genome Atlas Research Network have outlined five distinct expression subtypes of muscle-invasive bladder cancer, each of which may be targetable by different treatments.

A bladder-sparing approach for the treatment of muscle-invasive bladder cancer increases quality-adjusted life years compared with radical cystectomy in appropriately selected patients.

Trimodal therapy could offer superior overall survival versus radical cystectomy in certain subsets of patients with bladder cancer, according to a retrospective analysis presented at the 2017 Society of Urologic Oncology annual meeting in Washington.

Mitomycin C instillation within 24 hours after transurethral resection of non-muscle invasive bladder cancer significantly reduces the risk of recurrence and delays the time to recurrence.

"We will review the evidence and identify potential areas of improvement that can help reduce costs associated with UCB management while improving outcomes," write Daniel J. Lee, MD, and Sam S. Chang, MD.

Current NCCN guidelines are comparable to European models for predicting nonmuscle-invasive bladder cancer recurrence and progression. But better models are needed, according to a recent study.

Adding ramucirumab (CYRAMZA) to standard docetaxel (Taxotere) improved progression-free survival compared with docetaxel alone in patients with advanced or metastatic urothelial cancer who have progressed on platinum-based chemotherapy.

Blue light flexible cystoscopy (D-Light C PDD Flexible Videoscope System) with intravesical hexaminolevulinate HCl (HAL [Cysview]) for surveillance in the office setting significantly improved the detection of recurrent bladder tumors compared with white light cystoscopy.

"Overall, the take-home message is that [blue light cystoscopy], whether in the clinic or the OR, increases the detection of tumors," writes Jeffrey M. Holzbeierlein, MD.

Photothermal treatment with epidermal growth factor receptor-directed gold nanorods results in considerable antineoplastic activity in an early study of bladder cancer.

“rAd-IFNα gene therapy is a breakthrough opportunity for effective local management of BCG-unresponsive NMIBC,” says researcher Colin P. N. Dinney, MD.

Researchers from Wake Forest Baptist Comprehensive Cancer Center have made novel discoveries about the genomic signatures of cancers-including bladder cancer-in smokers and African-American patients.
