The Patient-Derived Tumor Xenograft (PDX): model is established by directly transplanting the patient's tumor tissue into immunodeficient mice. The characteristics of most primary tumors in histopathology, molecular biology and gene level, ensuring relatively reliable predictions of clinical efficacy . Therefore, the platform is widely used in the development of new drugs, especially in the selection of patients in clinical trials of target drugs and the study of predictive biomarkers.
