    Abstract:
    Serum ferritin concentration was studied in 136 patients with different types of acute leukemia. Pretreatment serum ferritin concentrations in the immature myeloblastic leukemia (M1 and M2 of the FAB-classification of acute leukemias) was found to be highly increased compared to the more mature types of acute myeloblastic leukemias (M3 to M5) and the acute lymphoblastic leukemias (L1 to L3). Investigation of the intracellular ferritin concentration showed, that the serum ferritin levels paralleled the intracellular ferritin concentration within the leukemic blasts. Within the immature myeloic blasts (M1) the intracellular ferritin concentration was 14-fold increased compared to normal granulocytes. This correlated with the 17-fold increased serum ferritin levels in these patients. Intracellular ferritin concentrations within the leukemic blasts of more mature types of acute leukemia (M3 to M5) were found to be only slightly increased. These data support the concept, that an increased synthesis and release of ferritin by the leukemic blasts is responsible for the increased serum ferritin concentration. This concept is also supported by the observation, that a further increase of serum ferritin concentration was seen during a cytotoxic chemotherapy. It is noteworthy, that this increase was more pronounced in the immature leukemias obviously caused by a loss of intracellular ferritin from the damaged leukemic blasts. The serum ferritin levels followed closely the activity of the disease. Increased pretreatment serum ferritin concentrations normalized completely when patients achieved complete remission. In contrast, in patients with tumor relapse or tumor progression serum ferritin concentrations increased again. These data suggest that the serum ferritin in immature myeloblastic leukemia has the characteristics of a tumor associated marker.(ABSTRACT TRUNCATED AT 250 WORDS)
