Tumor organoid-based drug sensitivity prediction is a new approach for precision medicine, which has wide applications in cancer treatment and attracts increasing attention. In the field of breast cancer, conventional organoid culture methods often require more than three weeks of culture period. The culture time greatly limits the further extension of the application scenarios of breast cancer organoids. We developed a fluid system that builds on the conventional organoid “dome” culture method, which continuously and stably supplies the nutrients for the growth of breast cancer organoids. We demonstrated that this is an effective optimization method, which can shorten the culture period of breast cancer organoids without significant changes in histological characteristics and drug sensitivity features.
