21 Curability of Patients With Acute Myeloid Leukemia Who Did Not Undergo Transplantation in First Remission Alan K. Burnett, Anthony Goldstone, Robert K. Hills, Donald Milligan, Archie Prentice, John Yin, Keith Wheatley, Ann Hunter, and Nigel Russell Conclusion Successful salvage treatment of patients who do not undergo transplantation in CR1 and relapse can be achieved in 19% of patients, which is improved by a transplant except in favorable risk disease. This result suggests that, for intermediate-risk patients in particular, equivalent overall survival can be achieved by delaying transplantation until after relapse, which would require many fewer transplants. 21
