The use of sodium 2-mercaptoethane sulfonate to prevent cyclophosphamide cystitis

In 2 patients receiving bone marrow transplantation sodium 2-mercaptoethane sulfonate has proved efficacious in preventing the serious problem of cyclophosphamide cystitis by regional detoxification of acrolein. We detail the first use of sodium 2-mercaptoethane sulfonate in the United States. We are cautiously enthusiastic and optimistic that the simultaneous administration of sodium 2-mercaptoethane sulfonate and cyclophosphamide will decrease if not eliminate cyclophosphamide-induced carcinoma.
