OBJECTIVE: To review the evidence for the management of anthracycline extravasation and determine the optimal treatment of such injuries.
DATA SOURCES: A search of MEDLINE (1966-February 2007) and International Pharmaceutical Abstracts (1970-February 2007) was performed using the search terms anthracyclines and extravasation.
DATA SYNTHESIS: Extravasation of anthracyclines can have devastating
effects. After infiltration of these drugs into the interstitial tissue,
damage may range from mild erythema and pain to severe tissue necrosis. Many
agents have been studied in the management of these injuries; however, few
have demonstrated efficacy and treatment remains controversial.
Nonpharmacologic modalities shown to limit extravasation injuries include
local tissue cooling and elevation of the affected area. Corticosteroids,
sodium bicarbonate, hyaluronidase, hyperbaric oxygen, heparin fractions,
-tocopherol, N-acetylcysteine, and granulocyte macrophage-colony
stimulating factor have all either been shown to be ineffective or have
limited data supporting their use. Topical dimethyl sulfoxide (DMSO) has been
shown in prospective studies to limit the course of extravasation injuries.
Dexrazoxane has been shown in animal models and case reports to be useful in
the management of anthracycline extravasation. Two recent prospective clinical
trials examining intravenous dexrazoxane 1000 mg/m2 within 6
hours of extravasation, 1000 mg/m2 24 hours after
extravasation, and 500 mg/m2 48 hours after extravasation
injuries add to the data supporting the use of this agent in such injuries. Of
the 54 patients enrolled, surgery-requiring necrosis was avoided in 98.2%.
CONCLUSIONS: The optimal treatment of anthracycline extravasation includes local tissue cooling, elevation of the afflicted extremity, dexrazoxane administration, and possibly topical DMSO. Many other drugs have been investigated; however, due to a lack of data, they cannot be recommended for the management of anthracycline extravasation.
