Neuron specific enolase (NSE) in serum of patients with malignant melanoma

Abstract

Serial measurements of serum NSE were performed in 63 patients with metastatic melanoma. NSE was measured by a sensitive immunoradiometric assay based upon monoclonal anti-bodies with monodisperse magnetizable particles as the solid phase. Increased NSE values were found in 30 patients (48%) during the course of the disease. In 10 patients serum NSE normalized during systemic therapy. In 11 patients with initial normal serum NSE, the marker values became elevated as the tumor progressed.
