Increased urinary excretion of m-octopamine in neuroblastoma.
The urine of three patients with neuroblastoma was found to have a 3 to 5-fold elevation of m-octopamine concentration. The concentration of m-synephrine was normal in two cases and slightly elevated in the third. These findings were attributed to an increased formation of m-octopamine by this tumor.
