摘　　要：Pancreatic cancer(PC)is a highly malignant tumor in the digestive system.The transformation of tissue from normal to pancreatic intraepithelial neoplasm is driven by certain oncogenes,among which the mutation rate of the KRAS gene is as high as 90%.Currently,PC has limited treatment options,low therapeutic effects,and poor prognosis.Thus,more effective methods to combat PC are urgently needed.Some models that can more accurately reflect the biological behaviors and genomic characteristics of PC,such as its morphology,pathology,proliferation,and invasion,are being continuously developed.These include genetic engineering models,orthotopic xenograft models,and heterotopic xenograft models.Using these PC models,scientists have further verified promising drugs and potential therapeutic targets for PC treatment.This is of great significance for limiting the progression of PC with clinical intervention,improving patient outcomes,and improving survival rates.
