Diagnostic and prognostic impact of urinary catecholamines in neuroblastoma patients

Abstract: Urinary catecholamines appear to be useful to give a first but important hint about the biological behavior and thus the prognosis of the underlying disease. Particularly DA/VMA ratio may serve as a tool for "biological grading"-especially in disseminated disease of infancy. In addition, it may be speculated that HVA negativity and low DA/VMA ratio may be helpful for the decision of a "wait and see" strategy in selected neuroblastoma patients with localized disease.

“…If the patient had no history of cancer, the diagnosis of orbital metastasis should prompt a systemic survey to detect a primary neoplasm and other sites of metastasis. With the availability of tumor markers, certain specific outcomes may provide us valuable clues, for example, increased alpha-fetoprotein (AFP) variants suggest the origin of the liver [18], vanillylmandelic acid (VMA) hint to the neuroblastoma [19], prostate-specific antigen (PSA) [20] indicating prostate cancer, and a high level of 5-hydroxy oxindole indicating the carcinoid [21].…”

“…All patients came from the southern provinces of China. The left orbit was affected more frequently than the right, with a ratio of 3:2 (27: 19), and no cases were bilaterally involved. Before the detection of the orbital lesions, 22 patients had a definite primary tumor history, in which the nasopharyngeal carcinoma was the most frequent, accounting for 50% of the cases.…”

“…12 If there is any question as to the diagnosis, this test should be performed and the results reviewed prior to surgery. The most surprising finding in the current investigation was that in children undergoing laparotomy for presumed WT, five patients actually had urinary VMA and/or HVA collected pre-operatively, indicating that NBL was entertained in the differential diagnosis.…”

“…Biochemical studies included the assay of catecholamine metabolites, that is vanillylmandelic acid and homovanillic acid in the urine (Strenger et al, 2007), and lactate dehydrogenase (LDH) assay in the serum. Vanillylmandelic acid, homovanillic acid, and LDH levels were considered to be abnormal if they exceeded twice the upper normal value.…”
