Extravasation of monoclonal antibodies
Abstract:
Introduction: Extravasation by conventional cytotoxics has been well documented. While monoclonal antibodies are not considered to have the necrotic potential of some cytotoxic medicines, they require appropriate management in case of extravasation. However, fewer data are available on their classification and appropriate management when extravasation occurs. As monoclonal antibodies are being more commonly used in current daily oncology practice, this is an issue that cannot be ignored.
Methods: A scientific literature review on PubMed was conducted. All findings were critically appraised independently by 6 clinical pharmacists in order to provide a classification according to the extravasation hazard.
Results: A classification of non-conjugated and conjugated monoclonal antibodies according to extravasation hazard has been elaborated for different molecules frequently used in oncology. In addition, general management, in case extravasation of monoclonal antibodies occurs, has been proposed and the role of the pharmacist in the extravasation process has been described.
Conclusion: A classification of hazard extent of extravasation of monoclonal antibodies with concurrent management based on literature data and expert consensus has been elaborated. In addition, the role of the oncology pharmacist is crucial in terms of follow-up and documentation of the extravasated monoclonal antibody and management is described.
