Summary
The iron status of 50 patients with Ph'-positive chronic granulocytic leukaemia (CGL) was evaluated at diagnosis by means of bone marrow and blood studies. A decreased or absent iron in semiquantitative estimation on bone marrow smears was observed in 92% of patients, and 88% had a low sideroblast score. In contrast, normal Hb and serum iron concentrations were found in the majority of cases, and only two out of the 50 patients displayed a decreased serum ferritin. To ascertain whether the bone marrow pattern of iron depletion could be due to an expansion of the red cell mass, the latter parameter was measured by isotopic methods in a subgroup of 11 patients. Normal or slightly increased values were obtained in all cases. We conclude that absent or decreased marrow iron is a common feature in the chronic phase of CGL, that generally does not reflect true iron deficiency. Since such a finding is also usual in polycythaemia vera and idiopathic myelofibrosis, it should be included among the features shared by the chronic myeloproliferative disorders.
