Progress and perspective of organoid technology in cancer-related translational medicine.

Organoids are in vitro simplified and miniature microcosms of internal organs, which have aroused great interest in tissue development, multiple disease models, clinical diagnosis, as well as high-throughput drug screening and personalized medicine and so on. The success of physiology-related organoid culture has greatly advanced the translational medicine research in the field of cancer treatment, which was once troubled by the inconsistency between two-dimensional (2D) cell culture and in vivo studies. Especially in recent years, the success rate of establish an organoid has been greatly improved, and the types of organoids have been gradually enriched. Moreover, the utilizing of some the cutting-edge technologies, including gene editing technology such as CRISPR-Cas9, the scope of application of organoid is broadened. In this review, we discuss the latest progress and applications of organoids, and also outline the potential challenges of organoids for future improvement.

Advances and Applications of Cancer Organoids in Drug Screening and Personalized Medicine.

In recent years, the rapid emergence of 3D organoid technology has garnered significant attention from researchers. These miniature models accurately replicate the structure and function of human tissues and organs, offering more physiologically relevant platforms for cancer research. These intricate 3D structures not only serve as promising models for studying human cancer, but also significantly contribute to the advancement of various potential applications in the field of cancer research. To date, organoids have been efficiently constructed from both normal and malignant tissues originating from patients. Using such bioengineering platforms, simulations of infections and cancer processes, mutations and carcinogenesis can be achieved, and organoid technology is also expected to facilitate drug testing and personalized therapies. In conclusion, regenerative medicine has the potential to enhance organoid technology and current transplantation treatments by utilizing genetically identical healthy organoids as substitutes for irreversibly deteriorating diseased organs. This review explored the evolution of cancer organoids and emphasized the significant role these models play in fundamental research and the advancement of personalized medicine in oncology.

Unlocking the potential of organoids in cancer treatment and translational research: An application of cytologic techniques.

Patient-derived organoid models hold promise for advancing clinical cancer research, including diagnosis and personalized and precision medicine approaches, and cytology, in particular, plays a pivotal role in this process. These three-dimensional multicellular structures are heterogeneous, potentially maintain the cancer phenotype, and conserve the genomic, transcriptomic, and epigenomic patterns of the parental tumors. To ensure that only tumor tissue is used for organoid development, cytologic validation is necessary before initiating the process of organoid generation. Here, we explore the technology of tumor organoids and discuss the fundamental application of cytology as a simple and cost-effective approach toward organoid development. We also underscore the potential application of organoid development in drug efficacy studies for lung cancer and head and neck tumors. Additionally, we stress the importance of using fine-needle aspiration to generate tumoroids.

Organoid technology in cancer precision medicine.

Organoid technology has been remarkably improved over the last decade. Various organoids have been derived from different types of tissues and recapitulate their organ-specific gene expression signatures, particular tissue spatial structures and functions of their original tissue. The patient-derived organoids (PDOs) have been used to elucidate crucial scientific questions, including the relationships between genetic/epigenetic alterations and drug responses, cell plasticity during disease progressions, and mechanisms of drug resistances. With the great expectations, PDOs will be widely used to facilitate the personalized medical decisions, which have the potential to profoundly improve patient outcomes. In this review, we will discuss the developmental details, current achievements, applications and challenges of organoid technology in precision cancer medicine.
