Panelists discuss how to manage the treatment of a 68-year-old woman with painless intermittent hematuria and positive cytology for high-grade urothelial cancer, addressing gender differences in diagnosis timing, the importance of repeat transurethral resection (TURBT) procedures, BCG therapy options, and considerations for radical cystectomy with pelvic organ preservation when BCG fails.

Panelists discuss how real-world data from a recent Mayo Clinic study confirms the promising efficacy and favorable safety profile of nadofaragene firadenovec in BCG-unresponsive non–muscle-invasive bladder cancer (NMIBC), highlighting high cystectomy-free and overall survival rates, with longer follow-up needed to assess response durability.

Panelists discuss how nogapendekin alfa, an intravesical immunotherapy that stimulates a localized immune response, combined with BCG therapy, provides a novel dual approach for treating BCG-unresponsive non–muscle-invasive bladder cancer (NMIBC), targeting both local and systemic immune responses.

Panelists discuss how they approach a typical bladder cancer case of a 79-year-old man with hematuria, including initial diagnostic procedures, the importance of proper tumor measurement during resection, BCG therapy protocols, and management options for BCG-unresponsive disease with a focus on nadofaragene firadenovec (Adstiladrin).

Panelists discuss how pembrolizumab, a PD-1 inhibitor, offers a systemic immunotherapy option for high-risk, BCG-unresponsive non–muscle-invasive bladder cancer (NMIBC) by enhancing the immune system’s ability to target cancer cells, with intravenous administration and careful monitoring for immune-related adverse effects.

Panelists discuss how recently FDA-approved therapies, including nadofaragene firadenovec, gemcitabine, and docetaxel, offer alternative treatment options for BCG-unresponsive high-risk non–muscle-invasive bladder cancer (NMIBC), each with distinct mechanisms and administration methods.

Panelists discuss how non–muscle-invasive bladder cancer (NMIBC) is staged, graded, and treated according to risk stratification, with detailed explanations of low-, intermediate-, and high-risk categories and corresponding treatment pathways.

Panelists discuss how maintenance BCG therapy and vigilant surveillance are essential for sustaining disease control in NMIBC patients, with treatment schedules and monitoring tailored to individual risk and tolerance.

Panelists discuss how timely identification of BCG-unresponsive NMIBC through defined response criteria enables dynamic risk stratification and guides critical decisions about escalating care to alternative treatments.

Panelists discuss how specific tumor characteristics, such as papillary architecture and presence of carcinoma in situ, guide risk-adapted treatment decisions in non–muscle-invasive bladder cancer.

Panelists discuss how precise risk stratification in non–muscle-invasive bladder cancer enables physicians to tailor treatment and surveillance strategies based on individual patient risk profiles.

The CR rate was 71% in patients with BCG-unresponsive NMIBC with CIS with or without papillary disease.

In this final episode, panelists conclude with reflections on the significant progress made in treating NMIBC over the past decade, particularly in the last 5 years. Looking ahead to 2024, experts in urology express excitement about investigational treatments (ie, cretostimogene grenadenorepvec and UGN 102), the potential for personalized medicine, emphasizing the need to understand molecular characteristics of the disease for better treatment customization. The session also highlights the importance of balancing quality of life with effective treatment strategies, and the prospect of utilizing emerging therapies early in the disease process.
