Abstract:
This article summarizes strategies being investigated in patients with nonmuscle invasive bladder cancer. Progress has been made toward improving the delivery method of intravesical agents. Intravesical therapy is limited by the amount of time that the agent remains in contact with the bladder. Bladder cancer is considered to be responsive to immune therapy. Thus, many novel approaches are immune-based therapies and include cancer vaccines, use of Bacillus Calmette-Guérin (BCG) subcomponents, and checkpoint inhibitors. Finally, access to bladder mucosa via direct catheterization into the bladder via the urethra has enabled unique strategies for delivery of cancer therapy including viral- or plasmid-based gene therapy.
Insights
Novel strategies for nonmuscle invasive bladder cancer focus on improving intravesical agent delivery and utilizing immune-based therapies like vaccines and checkpoint inhibitors for better bladder cancer treatment.
Area of Science:
- Oncology
- Urology
Background:
- Nonmuscle invasive bladder cancer (NMIBC) treatment faces challenges with intravesical agent efficacy.
- Limited contact time of intravesical agents in the bladder restricts therapeutic effectiveness.
Purpose of the Study:
- To summarize emerging strategies for NMIBC treatment.
- To highlight advancements in intravesical therapy delivery and novel immune-based approaches.
Main Methods:
- Review of current and investigational strategies for NMIBC.
- Focus on improving intravesical agent delivery methods.
- Exploration of immune-based therapies including vaccines, Bacillus Calmette-Guérin (BCG) subcomponents, and checkpoint inhibitors.
- Investigation of direct intravesical delivery of gene therapy via catheterization.
Main Results:
- Progress in enhancing the retention of intravesical agents within the bladder.
- Identification of bladder cancer's responsiveness to immunotherapy.
- Development of novel immune-based therapies showing promise.
- Emergence of gene therapy delivery strategies via catheterization.
Conclusions:
- Optimizing intravesical agent delivery is crucial for NMIBC management.
- Immune-based therapies represent a significant advancement in bladder cancer treatment.
- Direct intravesical delivery offers new avenues for targeted cancer therapy.
