Abstract

Esophageal adenocarcinoma (EAC) continues to be a significant public health problem with survival rates that have remained stagnant. Although the population at the highest risk for EAC, i.e., patients with Barrett’s esophagus (BE) has been clearly defined, patients with EAC continue to do poorly due to advanced stage at diagnosis. The field of extracellular vesicles (EV) could have huge application for the management of patients with BE and EAC by allowing timely diagnosis, serial monitoring, and improved understanding of disease biology. EV are actively packaged and actively secreted vesicles and contain microRNAs, proteins, lipids, and DNA. The contents of EV have been shown to provide useful insights into cellular transformation and pro-oncogenic processes. Early work shows promise but suffers from a high degree of technical and biological variation. The current review not only summarizes the current knowledge about EV as diagnostic biomarkers and their role in disease progression of BE and EAC but also provides the reader practical guidance to devise future experiments to perform well-designed studies.
