✦ Synopsis
Background. The records and initial bone marrow studies of 106 patients with newly diagnosed acute myelogenous leukemia (AML) were analyzed retrospectively to determine whether bone marrow dysplasia was predictive of a previous myelodysplastic disorder or correlated with remission rate and survival.
Methods. Bone marrow aspirates and biopsy specimens were reviewed in a blinded fashion; dysplasia was assessed in as objective a manner as possible by numerically scoring nine specific findings: erythrocyte multinuclearity, nuclear fragmentation, megaloblastic characteristics, leukocyte granulation abnormalities and nuclear malformations, Pelger-Huet cells, and megakaryocytic dysplasia (mononuclear megakaryocytes, micromegakaryocytes, and megakaryocytes with multiple distinct nuclei).
Results. Dysplasia of the megakaryocytic line was seen in 34% of patients; 70% of the patients had erythrocyte dysplasia; and 68% had leukocyte dysplasia. Pelger-Huet cells were seen in bone marrow of 35% of the patients. Overall dysplasia score and specific dysplastic findings such as Pelger-Huet cells did not correlate with a known history of myelodysplasia ( P = 0.47), cytogenetic abnormalities (P = 0.35), prior chemotherapy treatment with or without alkylating agents (P = l.OO), previous malignant disorders such as polycythemia Vera ( P = 1.00), remission rate (P = 0.93), or survival ( P = 0.42).
Multivariate analysis confirmed known independent
