Despite extensive research, the prognosis remains poor. Autophagy, a lysosomal-mediated, highly conserved degradation process that removes abnormal proteins and damaged organelles from the body, is upregulated in pancreatic ductal adenocarcinoma. Based on differences in the tumor microenvironment and tumor stage, the functions of autophagy in the pathophysiology and treatment of pancreatic cancer differ. In the initial phase, autophagy inhibits the transformation of precancerous lesions to cancer. However, in the progressive stage, autophagy promotes tumor growth. Autophagy is also one of the main mechanisms of drug resistance during treatment. Here, we describe the role of autophagy in pancreatic cancer progression and discuss relevant treatment strategies for this disease.Keywords: pancreatic ductal adenocarcinoma, cell growth, migration, tumor microenvironment, therapy
