摘要胰腺癌预后欠佳，以化疗及分子靶向治疗为代表的全身综合治疗是改善胰腺癌术后预后的关键，也是延长晚期胰腺癌生存时间的重要手段。但是由于胰腺癌细胞的耐药性、异质性等原因，目前的全身综合治疗方案仍未达到理想效果，基于精准医学的个体化胰腺诊疗模式将是解决这个问题的重要途径。随着人源性肿瘤组织异种移植(PDX)模型的应用，胰腺癌的个体化治疗方案的制定将成为可能。本文将在回顾胰腺癌PDX模型建立方法的基础上，对PDX模型在胰腺癌综合治疗中的应用进展进行综述，旨在为胰腺癌的个体化治疗提供新的思路。

abstractsPancreatic cancer has a poor prognosis, systemic comprehensive therapy including chemotherapeutic and molecular targeted therapy is the key to improve the postoperative prognosis of pancreatic cancer, as well as to prolong the survival time of advanced pancreatic cancer. However, due to the drug resistance and heterogeneity of pancreatic cancer cells, systemic comprehensive treatment still does not reach the ideal effect, and personalized therapy will be an important approach to solve this problem. The personalized therapy for pancreatic cancer will become possible with the application of patient-derived tumor xenograft (PDX) models. Here, this article will review the progress of the application of PDX models in comprehensive therapy of pancreatic cancer based on reviewing the methods of establishing pancreatic cancer PDX models, aiming to provide new ideas for personalized therapy of pancreatic cancer.
