Abstract

This study aims to summarize and visually analyze the current research status in pancreatic cancer immunotherapy during the past two decades by bibliometrics and explore the current research hotspots and future development directions. The literature related to pancreatic cancer immunotherapy from 2002 to 2021 was downloaded from the core database of the Web of Science. VOSviewer and CiteSpace software were used to visualize the included literature. A total of 2528 articles were included. In the past two decades, publications in the pancreatic cancer immunotherapy field have increased almost annually. As the country with the largest publications, the United States has various research institutions dedicated to pancreatic cancer immunotherapy. Jaffee EM and Zheng L from Johns Hopkins University and Vonderheide RH from the University of Pennsylvania have published the most articles in this field. The current research hotspots of pancreatic cancer immunotherapy include the tumor microenvironment, immune cells, immune checkpoint blockade, and combination therapy. The study of novel immunotherapies and combination therapy may become the primary focus of future research on pancreatic cancer immunotherapy. More prospective clinical studies with high evidence levels should be conducted.

Keywords: Pancreatic cancer; bibliometrics; immunotherapy; visual analysis.
