The clinical and hematological characteristics of 5 patients affected
with both acute myeloid leukemia (AML) and diabetes insipidus (DI) are
described. Banded chromosomal analysis demonstrated monosomy 7 in 2 p
atients and a complex cytogenetic rearrangement in another. No patient
entered complete remission with standard induction chemotherapy. Thes
e data confirm that in patients with AML, the association of DI (with
or without monosomy 7) is an unfavorable prognostic factor.
