Levels of serum manganese superoxide dismutase (Mn-SOD) in normal children aged from 1 to 14 years and children with various hematological and malignant diseases were determined by enzyme-linked immunosorbent assay (ELISA). In the normal children, the serum Mn-SOD levels gradually increased in proportion to age. By 8 years of age, the Mn-SOD level was nearly at the adult level. The normal values of serum Mn-SOD (mean +/- SD) of children below 4 and above 8 years old were 48 +/- 10.2 ng/ml and 84 +/- 22.5 ng/ml, respectively. Assuming the upper limit of normal Mn-SOD level in serum to be the mean value +/- 2 SD of children at each age, high serum levels of Mn-SOD were found for 8 of 12 patients with neuroblastoma, three of four patients with Wilms tumor, and four of five patients with acute myeloid leukemia. The patients with neuroblastoma exhibited a transient increase in Mn-SOD following chemotherapy, but after 1 week the levels decreased markedly to the control levels. The changes in serum Mn-SOD levels in the patients with neuroblastoma correlated well with the levels of neuron-specific enolase. Mn-SOD was intensely stained in bone marrow cells of patients whose cancer cells had moved into the bone marrow. High levels of Mn-SOD were also found in cultured human neuroblastoma cells. These data indicate that Mn-SOD is expressed in neuroblastoma cells, may serve as one of the diagnostic and prognostic markers for the neuroblastoma, and may be useful to predict the effectiveness of chemotherapy for neuroblastoma and the recurrence of this disease.
