Neuron-specific enolase as a prognostic factor in metastatic malignant melanoma

Abstract

Serum neuron-specific enolase (NSE) was measured in 63 patients with metastatic malignant melanoma. 20 patients (32%) had elevated serum NSE (> 10 μg/l) before the start of treatment. Another 13 patients (21%) developed pathological NSE values during the course of the disease. In many patients, elevated NSE was related to a large tumour burden, and a gradual rise in serum NSE indicated disease progression. Patients with elevated pretreatment NSE had a median survival time of 3 months compared with 12 months for those with normal pretreatment NSE values. NSE thus proved to be a useful prognostic factor in metastatic malignant melanoma.
