EGFR-directed antibodies increase the risk of severe infection in cancer patients

摘要

Monoclonal antibodies directed to the epidermal growth factor receptor (EGFR) have a role in the management of several solid tumors, alone or in combination with chemotherapy or radiation therapy. Recognized toxicities have included hypersensitivity reactions, rash, hypomagnesemia, and constitutional symptoms, but the possibility that the agents lead to immunosuppression or increase the risk of infection has only recently been recognized. Two latest meta-analyses, including the recently published article by Qi et al., highlight the increased risk of severe infections with EGFR-directed monoclonal antibodies. Further studies are needed to better identify the association between EGFR-directed monoclonal antibody treatment and infection, as well as to elucidate the mechanism of this toxicity and to develop tools to identify patients at increased risk for these complications. In the meantime, awareness of the role of EGFR-directed antibodies in increased infection risk may have implications for dose modification strategies in both clinical trial design and the practice of oncology.Please see related article: .
