Question:
Date of diagnosis: Can a positive VMA:HVA test be used as a date of diagnosis for neuroblastoma? See Description.
Discussion:
Rubin's Clinical Oncology states: Both the catecholamines and their metabolites are used as markers for neuroblastoma, with vanillylmandelic acid (VMA) and homovanillic acid (HVA) being the most commonly used. While their absolute values are not of prognostic significance, a higher VMA:HVA ratio suggests a better prognosis for patients with disseminated disease.
Answer:
Updated answer July 2024
No. Do not code the neuroblastoma diagnosis date from only the date of an elevated urine catecholamine test (VMA or HVA). Neuroblastoma diagnosis should be made on the basis of tissue biopsy or bone marrow aspiration along with elevated urinary catecholamines. Elevated urinary catecholamines alone are not diagnostic of neuroblastoma.
