The deoxyadenosine analogue 2-chlorodeoxyadenosine is an effectiveand relatively nontoxic treatment for hairy-cell leukemia1 andother B-cell neoplasms, including chronic lymphocytic leukemia(CLL)2,3. In a recent study of 90 patients with CLL, including62 with advanced disease, the overall rate of response was 44percent, the most severe toxic effect being myelosuppression4.Excellent responses were recently reported in four patientswho did not respond to fludarabine therapy, with myelosuppressionas the only untoward side effect5. We report the occurrenceof tumor lysis syndrome after the infusion of 2-chlorodeoxyadenosinein a patient with CLL and bulky lymphadenopathy.
