Iron stores in chronic granulocytic leukaemia at presentation

Abstract
In 87 patients with Ph1 positive chronic granulocytic leukaemia (CGL), the bone marrow iron content was studied on smears obtained at diagnosis. A low sideroblast score and a decreased or absent marrow iron on semiquantitative estimation were found in 91 % and 85 % of cases, respectively. These findings did not correlate with blood parameters reflecting iron status such as Hb concentration, mean corpuscular volume, mean corpuscular haemoglobin, serum iron, total iron‐binding capacity and transferrin saturation, which were normal in most cases. In 30 patients, initial serum ferritin was estimated, normal or slightly increased levels being as a rule found. In 24 of such patients, serum ferritin was again measured in remission following busulphan and, although values remained normal, a significant decrease was observed with respect to the initial levels (P < 0.001). Thus, in spite of the consistent marrow pattern of iron depletion, initial iron stores appear to be normal in CGL. It seems, however, that the disease activity may partially influence the serum ferritin levels.
