Prevention of cytotoxic drug induced skin ulcers with dimethyl sulfoxide (DMSO) and alpha-tocopherole.

Accidental subcutaneous extravasation of several antineoplastic agents may provoke skin ulcerations for which there has been no simple and effective treatment. Since January 1983 we have treated all patients in our institution sustaining extravasation by a cytotoxic drug with a combination of DMSO and alpha-Tocopherole. During the first 48 hr after extravasation a mixture of 10% alpha-Tocopherole acetate and 90% DMSO was topically applied. The bandage was changed every 12 hr. So far eight patients with extravasation of an anthracycline or Mitomycin were treated on this protocol. No skin ulceration, functional or neurovascular impairment occurred in any of these patients. The only toxic effect observed by this treatment was a minor skin irritation. The combination of DMSO and alpha-Tocopherole seems to prevent skin ulceration induced by anthracyclines and Mitomycin.
