Background And Purpose:
BCG unresponsive bladder cancer is an inherently resistant disease state for which the preferred treatment is radical cystectomy. To date, no effective intravesical therapies exist for patients who possess these resistant tumors. For this reason, many research groups are actively investigating/testing novel therapeutic agents to aid in bladder preservation for this patient population. This review article describes our 15-year experience developing and testing IFN-based gene therapy.
Methods:
A comprehensive review was performed of all studies pertaining to IFN-based gene therapy for non-muscle invasive bladder cancer from 2003 to 2018.
Results And Conclusions:
Over the past two decades, gene therapy has evolved into a powerful tool in our fight against cancer. After overcoming the initial barriers associated with gene delivery to the bladder, we have made significant strides forward in developing this novel therapeutic strategy for the treatment of this inherently resistant disease state. Our results to date are very encouraging; however, much work lies ahead to better understand and optimize this novel approach for treating non-muscle invasive bladder.
Insights
Interferon (IFN)-based gene therapy shows promise for treating BCG-unresponsive bladder cancer, offering a potential bladder-preserving alternative. Further research is needed to optimize this novel approach for non-muscle invasive bladder cancer.
Area of Science:
- Oncology
- Gene Therapy
- Urology
Background:
- BCG-unresponsive bladder cancer presents a significant therapeutic challenge, often necessitating radical cystectomy.
- Currently, no effective intravesical therapies exist for patients with these resistant bladder tumors.
- Novel therapeutic agents are under investigation to facilitate bladder preservation in this patient population.
Purpose of the Study:
- This review details a 15-year experience in the development and testing of interferon (IFN)-based gene therapy.
- The study aims to assess the efficacy of IFN-based gene therapy for bladder cancer.
- Investigating novel strategies for bladder preservation in patients with non-muscle invasive bladder cancer.
Main Methods:
- A comprehensive literature review was conducted.
- Studies included were focused on IFN-based gene therapy for non-muscle invasive bladder cancer.
- The review period spanned from 2003 to 2018.
Main Results:
- Gene therapy has emerged as a potent anti-cancer tool over the last two decades.
- Significant progress has been made in overcoming challenges related to gene delivery to the bladder.
- IFN-based gene therapy demonstrates encouraging results for treating resistant bladder cancer.
Conclusions:
- IFN-based gene therapy represents a promising novel therapeutic strategy for non-muscle invasive bladder cancer.
- Despite encouraging outcomes, further research is essential to optimize this approach.
- Continued investigation is required to fully understand and refine IFN-based gene therapy for bladder cancer treatment.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
