Dear Colleagues,
Since I am asked by the editor to prevent Dr. Gale and Dr. Moiseev from slugging it out, I would like to find positions where we can meet:
1) The informed consent for any treatment particularly with the risks for the patient will require a complete disclosure of risks and alternative treatments (Declaration of Helsinki, Belmont report). If we recommend a transplant to a patient with AML in first remission at intermediate risk, we have to tell them how they would fare with conventional treatment [1-3].
2) Knowing the dilemma of our prediction capability. Hematologists and transplanters work for more than 40 years on refinement of predictive models. The predictive model by Smith and Keating has been applied to a patient group with acute leukemia and could show a survival advantage for transplants in the high and intermediate, but not in the good risk group [4, 5].
3) The current EBMT recommendations state AML patients with good cytogenetic features are not: patients with intermediate and poor risk, are candidates for transplant in first CR [6-10].
4) Risk Assessment integrating cytogenetic and molecular profiling might improve the predictability [11].
5) Since the age represents one of the most adverse prognostic indicators for response to treatment and overall survival and since the results of transplant in patients older than 60 years have improved significantly, further emphasis should be directed towards elderly AML patients to sort out age risk factor versus molecular and cytogenetic markers [12].
6) As to the ornithological questions, how to overcome the black and white swans [13]. I would like to point to Cocoanuts
1929, the Marx Brothers: “Why a duck?”[14].
7) As to the slugging it out, I would like to recommend the Bavarian method to drown the dispute in beer until everything is clear and the question forgotten.
Sincerely,
Axel Rolf Zander, MD, Dr.h.c., FACP
