## Abstract We reviewed our records for the last 10 years and found three of the 36 patients with neuroblastoma did not excrete significantly increased quantities of catecholamine metabolites in urine. All of these tumors were histologically characterized by small round cells and possessed a few de
Neuroblastomas are malignant tumors derived embryonically from the neural crest. Biological diagnosis relies on assay of urinary excretion of homovanillic acid (HVA), vanillylmandelic acid (VMA), and dopamine (DA). Spontaneous regression of these neoplasms has been reported by numerous investigators
## Abstract Assays of urinary catecholamines and their metabolites (HVA, VMA, dopamine) permit biochemical diagnosis of neuroblastoma in approximately 80% of patients. The urinary methylated catecholamine metabolites normetanephrine (NMN), metanephrine (MN), and 3βmethoxytyramine (3βMT) were analyz
