Abstract
Intravesical therapy is a critical component in the management of non-muscle-invasive bladder cancer (NMIBC), as it reduces rates of disease recurrence and progression. However, the presence of physiologic barriers in the urothelium reduces the penetration and distribution of intravesical chemotherapy, thereby limiting the therapeutic potential. Much progress to overcome this challenge has been made in the realm of intravesical device-assisted therapy. Novel device-assisted treatments include hyperthermia, the radiofrequency-induced thermochemotherapy effect, electromotive drug administration, and implantable drug delivery systems. Notably, chemotherapy enhanced by these device-assisted systems has shown improved oncologic efficacy relative to standard intravesical chemotherapy and comparable outcomes relative to Bacillus Calmette-Guérin (BCG) therapy in patients with intermediate- or high-risk NMIBC. Recent studies also support the utility of device-assisted therapy as a salvage treatment option in patients with BCG-unresponsive disease. Ongoing randomized controlled trials and prospective investigations will further help clarify indications and long-term safety outcomes of these treatment modalities in NMIBC. Herein, we present a comprehensive review of device-assisted therapies and discuss their clinical utilities for the management of NMIBC in the modern era.
期刊介绍：
Bladder Cancer is an international multidisciplinary journal to facilitate progress in understanding the epidemiology/etiology, genetics, molecular correlates, pathogenesis, pharmacology, ethics, patient advocacy and survivorship, diagnosis and treatment of tumors of the bladder and upper urinary tract. The journal publishes research reports, reviews, short communications, and letters-to-the-editor. The journal is dedicated to providing an open forum for original research in basic science, translational research and clinical medicine that expedites our fundamental understanding and improves treatment of tumors of the bladder and upper urinary tract.
