Organoids as Sophisticated Tools for Renal Cancer Research: Extensive Applications and Promising Prospects

Kidney cancer is a significant global health problem that affects nearly 1 in 25 of cancer patients. Prevalence, morbidity and mortality data associated with kidney cancer continue to increase every year, revealing a heavy economic and social burden. Organoid culture is a new research tool with great potential for many applications, particularly in cancer research. The integration of organoids with other emerging technologies has simultaneously expanded their potential applications. However, there is no thorough assessment of organoids in the field of renal cancer research.

This paper presents a comprehensive review of the current development of renal cancer organoids and discusses the corresponding solutions and future directions of renal cancer organoids.

In this study, we have compared the operating procedures of different organoid culture protocols and proposed a summary of constituents in culture media. Extensive discussions of renal cancer organoids, including generation and maintenance approaches, application scenarios, current challenges and prospects, have also been made. The information required for this study is extracted from literature databases such as PubMed, SCOPUS and Web of Science.

In this article, we systematically review thirteen successful methods for generating organoids to kidney cancer and provide practical guidelines for their construction as a reference. In addition, we also elucidate the clinical application of organoids, address the existing challenges and limitations, and highlight promising prospects.

Ultimately, we firmly believe that as kidney tumour organoids continue to develop and improve, they will become a crucial tool for treating kidney cancer.
