Nanomedicine in Bladder Cancer Therapy

Area of Science:

• Oncology
• Nanomedicine
• Materials Science

Background:

• Bladder cancer (BC) is a prevalent genitourinary malignancy with significant treatment challenges.
• Traditional therapies like chemotherapy and immunotherapy face limitations including poor specificity, cytotoxicity, and drug resistance.
• Emerging research explores nanotechnology as a novel therapeutic strategy for bladder cancer.

Purpose of the Study:

• To review the application of nanotechnology in treating non-invasive (NMIBC) and invasive (MIBC) bladder cancer.
• To discuss various nanoparticle types, targeting mechanisms, and nanotherapeutics for oncological applications.
• To explore nanoformulations in phototherapy, gene therapy, and immunotherapy for bladder cancer.

Main Methods:

• Comprehensive literature review of nanotechnology applications in bladder cancer treatment.
• Analysis of different nanoparticle carriers (chitosan, liposomes, polymeric, protein-based, superparamagnetic iron oxide).
• Examination of targeting strategies and clinical translation challenges.

Main Results:

• Nanoparticles facilitate targeted drug delivery and prolonged retention in bladder cancer tissues, enhancing therapeutic efficacy.
• Various nanoformulations show promise in phototherapy, gene therapy, and immunotherapy for bladder cancer.
• Approved nanotherapeutics with oncological implications are discussed.

Conclusions:

• Nanotechnology presents a promising avenue for overcoming limitations in current bladder cancer therapies.
• Further research and clinical translation are essential to realize the full potential of nanomedicine in bladder cancer treatment.
• Nano-based strategies offer improved specificity and efficacy for both NMIBC and MIBC.
