Application and challenges of smart responsive multifunctional nanoplatforms in integrated diagnosis and treatment of bladder cancer and overcoming therapeutic resistance

Sep 23, 2026

Uploaded by Terk

Bladder cancer—especially muscle-invasive disease—poses major clinical challenges due to high recurrence and therapeutic resistance. Conventional modalities such as transurethral resection, intravesical chemotherapy, and radical cystectomy are limited by suboptimal drug delivery efficiency and insufficient anti-resistance activity. Smart, responsive, multifunctional nanoplatforms are highlighted for tumor microenvironment–responsive, targeted, and controlled release, supporting multimodal combination therapy. This review outlines design principles, specific diagnostic and treatment applications, and engineering and safety obstacles during translation, proposing future strategies for advancing precision bladder cancer nanomedicine.

Traditional treatments—including transurethral resection of bladder tumors, intravesical chemotherapy, and radical cystectomy—exhibit signiﬁcant limitations in drug delivery efﬁciency and anti-resistance efﬁcacy, failing to achieve improved therapeutic outcomes. In recent years, smart, responsive, and multifunctional nanoplatforms have gained attention for their precise responsiveness to the tumor microenvironment, enabling targeted and controlled drug release, as well as multimodal combination therapy with promising clinical applications. This review examines the design principles of smart, responsive nanoparticles and their speciﬁc applications in the integrated diagnosis and treatment of bladder cancer, exploring their role and advantages in overcoming therapeutic resistance mechanisms. Additionally, it analyzes engineering challenges and safety concerns encountered during the transition from laboratory research to clinical translation, proposing future development strategies and countermeasures. The review aims to provide systematic theoretical support and practical guidance for innovative developments in bladder cancer nanomedicine, thereby advancing the ﬁeld of precision medicine.

MIBC patients exhibit poor survival rates, with disease mortality constituting a major component of bladder cancer-related deaths (1) . Current standard treatments for MIBC primarily involve radical cystectomy, radiotherapy combined with Frontiers in Oncology 01 [frontiersin.org](frontiersin.org) cisplatin-based chemotherapy, and other approaches. However, traditional therapies invariably induce signiﬁcant side ef

FAQs

Why is muscle-invasive bladder cancer difficult to treat?

It has high invasiveness and recurrence rates, along with complex treatment requirements and generally poor survival outcomes.

What limits current standard therapies and contributes to recurrence?

Traditional treatments can produce significant side effects and often induce therapeutic resistance; cisplatin resistance is described as a primary driver of recurrence and failure.

How do smart responsive multifunctional nanoplatforms improve diagnosis and treatment?

They respond to the tumor microenvironment to enable targeted, controlled drug release and multimodal combination therapy, aiming to overcome resistance mechanisms while supporting translational development.
