Age dependence and prognostic impact of neuron specific enolase (NSE) in children with neuroblastoma.
Serum neuron specific enolase (NSE) was determined in 159 patients with neuroblastoma at diagnosis and in 183 children of various age groups. We found an age dependence of reference intervals for NSE and defined the 95th percentiles as upper normal limits. The specificity was 91.3% and the sensitivity 73.0%. The incidence of abnormal NSE levels increased with stage. The NSE serum levels were not influenced by histologic differentiation. Neuron specific enolase proved to be a reliable tumor-marker for monitoring the disease. Moreover, abnormal NSE values at diagnosis were of prognostic significance for patients with localized neuroblastoma (stages I-III) and for children with metastatic disease (stage IV), but not for infants with stage IV S. In comparison to catecholamine metabolite determination neuron specific enolase appeared to be a slightly less specific, equally sensitive tumor marker but with prognostic information for children with neuroblastoma.
