BACKGROUND

Bladder cancer (BC), one of the most prevalent and aggressive urological malignancies, poses significant challenges in diagnosis, treatment, and recurrence management. Patient-derived organoid provides new directions for the precision diagnosis and treatment of bladder cancer.

OBJECTIVE

To make a comprehensive summary of the current bladder cancer organoid studies.

METHODS

A comprehensive database search was conducted to provide an in-depth overview of the current state of bladder cancer organoid models, with a focus on their applications in basic research, clinical translation, and therapeutic discovery.

RESULTS

We summarized the current bladder cancer organoid studies, highlighting their advantages, such as genetic fidelity and high-throughput drug screening capabilities. Additionally, we also address the challenges, including their limited representation of the tumour microenvironment and technical complexity. Finally, we discuss future directions, including the integration of immunotherapy, the development of co-culture systems, and the exploration of non-invasive sampling methods and organoid-on-chip systems.

CONCLUSIONS

Traditional pre-clinical models have inherent limitations in mimicking the complexity of human tumours. The emergence of organoid technology has offered a groundbreaking approach to address this challenge, providing an innovative tool for studying tumour biology, genetic alterations, drug screening, and personalized medicine in bladder cancer.
