title: Urinary arylsulfatase in normal children and in patients with pediatric malignant disease.
abstract: Urinary arylsulfatase (AS) activities were measured in 20 normal children and 10 patients with malignant disease, consisting of leukemia (6), Hodgkin's disease (1), neuroblastoma (2), and malignant teratoma (1), Seven of the patients showed a significantly high activity, and a serial measurement carried out in 4 patients showed a well correlated relationship between AS activity and the activity of disease. Thus the measurement of urinary AS activity could be a laboratory test for monitoring the activity of malignant diseases because of its simple and rapid procedure.
