Objective:To improve the standardization and normalization of the in vitro evaluation of immune cell therapies and accelerate their clinical transformation process. Methods:An evaluation strategy for the anti-tumor effects of immune cell therapies, based on tumor organoid and organoid-on-chip models was formulated, through analyzing the characteristics of the evaluation of the effectiveness of immune cell therapies and the application potential of organoid and organ-on-chip technologies, and referring to internationally advanced guidelines for organoid and organ-on-chip evaluation, as well as the latest domestic and international research findings. Results and Conclusion:A consensus was formed on the application of tumor organoid and organoid-on-chip models in the evaluation of the anti-tumor effects of immune cell therapies. This consensus addressed their advantages, biological requirements, characterization criteria, experimental design and limitations: First, tumor organoid and organoid-on-chip models provide a more reliable and efficient tool for evaluating the efficacy of immune cell therapies. Second, the cell types and origins used in the model, culture conditions, and the tumor microenvironment should be taken into consideration before the evaluation. Third, the evaluation must include morphological, histopathological, genetic and biological functional characterization of tumor organoids, together with validation of anti-tumor effects. Fourth, the assay should set up appropriate control groups, determine the optimal ratio of effector cells to target cells, and select appropriate detection endpoints. Fifth, this approach still faces challenges such as insufficient pathological relevance and standardization of the models. In the future, it is necessary to further enhance the pathological relevance and standardization of tumor organoid and organoid-on-chip models to improve their predictive ability and to better facilitate the development and transformation of immune cell therapies.
