Urinary cystathionine, catecholamine, and metabolites in patients with neuroblastoma.
Urinary excretions of cystathionine, catecholamines, and vanillymandelic acidwere compared in 27 patients with neuroblastoma and in nine other patients with non-neurogenic tumors. Eleven of the 27 patientswere withoutclinical evidence of activeneuroblastomaatthe time ofthe study and excretedno or relatively small amounts of urinarycystathionine. Thirteenof the remaining 16 patients with progres...
متن کاملSymptomatic pheochromocytoma with normal urinary catecholamine metabolites.
A 61-year old female presented with paroxysmal hypertension and a 4.5cm left adrenal mass on CT scan. Repeated measurements of 24-hour urinary fractionated metanephrines, total catecholamines and vanillylmandelic acid (VMA) were within normal range. A further scintigraphic study with (131)I -metaiodobenzylguanidine ((131)I-MIBG) revealed selective concentration of the radiotracer, corresponding...
متن کاملPrognostic value of ferritin, neuron-specific enolase, lactate dehydrogenase, and urinary and plasmatic catecholamine metabolites in children with neuroblastoma
Different plasma and urinary parameters have been tested as valuable prognostic markers for children with neuroblastoma (NB), but conclusive results from multivariate analyses are still lacking. Samples collected at diagnosis from 505 patients diagnosed in Italy between June 1994 and November 2010 were analyzed at the Italian reference laboratory according to standard methodologies. Patient cli...
متن کاملGas-chromatographic profiling of urinary acidic and alcoholic catecholamine metabolites.
Urinary acidic and alcoholic catecholamine metabolites were isolated separately from 24-h urines by simple extraction procedures. After derivatization, extracts were analyzed by means of simultaneous gas chromatography on two different stationary phases. The quality of the assay was checked by running "normal" and enriched commercial (Hyland) control urines in each series. Normal values are giv...
متن کاملUrinary and plasma catecholamines and urinary catecholamine metabolites in pheochromocytoma: diagnostic value in 19 cases.
We review our data on the measurement of catecholamines and their metabolites in 19 patients with pheochromocytoma. All the assays were specific high-performance liquid chromatographic procedures with electrochemical detection. The assay of fractionated metanephrines was 100% sensitive. Normal values for both urinary norepinephrine and epinephrine were found in two asymptomatic patients with ph...
