What Researchers Did
Researchers reviewed existing medical studies to find the best ways to treat injuries caused by anthracycline drugs leaking out of blood vessels.
What They Found
The review found that many treatments for anthracycline extravasation, including hyperbaric oxygen therapy, had limited or no evidence of effectiveness. However, local tissue cooling and elevation of the affected area were helpful. In two clinical trials, intravenous dexrazoxane prevented the need for surgery in 98.2% of 54 patients when given within 48 hours of the injury.
What This Means for Canadian Patients
For Canadian patients undergoing chemotherapy with anthracyclines, this study suggests that if the drug leaks out of the vein, immediate steps like cooling the area and elevating the limb are beneficial. The review also indicates that intravenous dexrazoxane could be a very effective treatment to prevent severe tissue damage and surgery. Hyperbaric oxygen therapy was not found to be an effective treatment for these injuries.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study's conclusions are limited by the overall lack of strong evidence for many of the treatments reviewed for anthracycline extravasation injuries.
