The secretion of ibuprofen metabolites interferes with the capillary chromatography of urinary homovanillic acid and 4-hydroxy-3-methoxymandelic acid in neuroblastoma diagnosis

Neuroblastoma is the most common extracranial solid tumor in children. Abnormal secretion of catechol-amines in tissues and body fluids allows for the differential diagnosis of neuroblastoma from other neoplasms and its distinction from non-neoplastic inflammatory diseases...
