Research findings, 'HPLC-mass spectrometry method for quantitative detection of neuroendocrine tumor markers: vanillylmandelic acid, homovanillic acid and 5-hydroxyindoleacetic acid,' are discussed in a new report. "The urinary excretion of vanillylmandelic acid (VMA), homovanillic acid (HVA) and 5-hydroxyindoleacetic acid (5-HIAA) can be increased in the presence of neuroblastic and carcinoid tumors. The former is characterized by defective catecholamine metabolism which results in high urinary levels of VMA and HVA," scientists writing in the journal Clinica Chimica Acta report.
"The latter shows an altered metabolism of tryptophan and an increased synthesis of...
