Long-term disease-free survival in acute nonlymphocytic leukemia
BA Peterson and CD Bloomfield
Twenty-six of 45 adults (58%) with acute nonlymphocytic leukemia who were
treated with intensive induction chemotherapy over 5 yr ago entered
complete remission. All patients entering remission were placed on weekly
maintenance chemotherapy consisting of cytosine arabinoside and
6-thioguanine. The median duration of complete remission was 17 mo and 7
patients (27%) remained in their initial remission for 62 + to 102 + mo.
All but one of the patients in complete remission over 5 yr have had
treatment discontinued. Only 1 of 7 patients in remission for more than 5
yr has relapsed. Median survival is 26.5 mo, and 8 patients (31%) currently
remain alive without evidence of leukemia 63--105 mo from diagnosis. It is
possible to achieve long-term disease-free survival with chemotherapy alone
in acute nonlymphocytic leukemia.
