Stainable iron was absent or decreased in 36 of 45 bone marrow biopsy specimens (80 percent) among 33 patients with chronic-stage chronic granulocytic leukemia. Decreased iron did not correlate with sex, treatment status, duration of disease, marrow cellularity, or hemoglobin level. In contrast, marrow iron was absent or decreased in 34 percent of biopsy specimens at diagnosis of acute nonlymphocytic leukemia (p less than 0.0001) and 31 percent of biopsy specimens from patients with Hodgkin's disease (p less than 0.0001). The serum ferritin level was determined in eight patients with chronic granulocytic leukemia and absent marrow iron, and it was normal in all. Fifteen of 17 patients, followed with chronic-stage disease for one to four years after the finding of absent marrow iron, demonstrated increases in their hemoglobin levels during antileukemic therapy or maintained normal values. Thus, absent or decreased stainable marrow iron is a common finding in chronic granulocytic leukemia and usually does not indicate iron deficiency.

After evaluating multiple tests, the authors have devised a scheme to predict bone marrow iron findings from tests performed on peripheral blood. They examined bone marrows from 97 consecutive patients with anemia who were divided into five marrow morphologic groups: (1) iron deficiency; (2) anemia of chronic disease; (3) abnormal sideroblasts; (4) ring sideroblasts; and (5) other. Tests of peripheral blood included hemoglobin, hematocrit, red blood cell count and red blood cell indices, reticulocyte count, sedimentation rate or zetacrit, ferritin, iron, iron binding capacity, free erythrocyte protoporphyrin, and tests of hepatic and renal function. Cluster analysis, multidimensional scaling, and logistic discriminant analysis were used to derive a graph of serum ferritin with the sedimentation rate, allowing accurate confirmation or exclusion of iron deficiency in most patients. Percent saturation of serum transferrin and serum ferritin allowed identification of only 50 percent of patients with abnormal or ring sideroblasts while excluding 100 percent of patients without abnormal or ring sideroblasts. In three years of follow-up, two of 19 patients with abnormal or ring sideroblast have developed the dysmyelopoietic syndrome or ANLL, respectively. With the aid of the two parameter graphs described, the authors believe the differential diagnosis of the hypoproliferative anemias relating to iron metabolism can frequently be made without examination of the bone marrow.
