Abstract:
Objective:To establish the patient derived xenograft (PDX) model of liver malignant tumor, analyze the related factors affecting the carcinogenesis of PDX model, and analyze the differences of biological characteristics between the primary tumor and PDX model.Methods:Fresh liver malignant tumor tissue samples were collected from the patients who received the surgery from the Tianjin First Central Hospital and the samples were inoculated subcutaneously into BALB/c-nu mice. The correlations between clinicopathological information and tumor formation rate were analyzed, and the pathological morphology and specific protein expression of PDX model and primary tumor were compared.Results:Thirty-three PDX models were successfully established from 63 cases of liver malignant tumors. The overall tumor formation rate was 52.4% (33/63), including 46.3% (25/54) of primary liver cancer and 88.9% (8/9) of liver metastasis. The main factors affecting the tumor formation rate were tumor pathological type, distant metastasis and TNM stage (all P<0.05). The pathological morphology and specific protein expression of PDX model and primary tumor were similar. Conclusion:The PDX model of liver malignant tumor was successfully constructed, and the tumor formation rate was high, and can maintain the biological characteristics of the primary tumor.
