Remission induction with adenosine-deaminase inhibitor 2'-deoxycoformycin in Thy-lymphoblastic leukaemia
Abstract
Two patients with relapsed acute lymphoblastic leukaemia of thymic phenotype (Thy-ALL) resistant to all conventional chemotherapy achieved complete remission when treated with 2'-deoxycoformycin, a selectively lymphocytotoxic compound that acts by inhibition of the enzyme adenosine deaminase. These observations show that malignant thymocytes are dependent on adenosine-deaminase activity and suggest that it may be possible to use deoxycoformycin in other patients with Thy-ALL to induce remission or to kill Thy-ALL blasts in bone marrow harvested before autologous bone-marrow transplantation, leaving normal haemopoietic stem cells intact.
