How to define and manage borderline resectable pancreatic cancer

Abstract

Historically, borderline resectable (BLR) pancreatic cancer has had many definitions, which has made interpretation of treatment data and outcomes difficult. Advances in imaging, surgical technique, and the potential benefit of neoadjuvant therapy have emphasized the need for uniform classification. Despite recent efforts to provide a clearer definition, prospective randomized trials are lacking in the literature. This article reviews current definitions, treatment sequences, outcomes, and prognostic factors associated with BLR pancreatic cancer. Further clarification and consensus on the definition of BLR pancreatic cancer will allow for further data collection and cooperation in future efforts to make progress and standardize treatment.
