Epidermal growth factor receptor (EGFR)-targeted therapies in mesothelioma

摘要

Introduction: Malignant mesothelioma (MM) is an aggressive malignancy arising from the mesothelial cells lining the pleura and other serosal membranes. It is associated with an extremely poor prognosis and has limited therapeutic options. Areas covered: Epidermal growth factor receptor (EGFR) is known to be highly overexpressed in mesothelioma with reported EGFR overexpression between 44 to 97%. Given this, several anti-EGFR agents have been trialed in mesothelioma. In this review, we provide an overview of the current available data on anti-EGFR therapies in MM and future directions of investigation with these targeted agents in MM. Expert opinion: While many anti-EGFR therapies have failed to show significant efficacy in the management of MM, the pathway is biologically active and its abrogation preclinically points toward it being a valid target. Toward targeting the pathway, many novel EGFR-based therapies are still being investigated. Current ongoing research of interest in MM include EGFR-targeted nanotechnology approach for drug delivery, antibodies targeting the extracellular EGFR and potentially anti-EGFR antibody drug conjugates.
