[Determination of VMA/Cr and HVA/Cr in random urine collection for the diagnosis of neuroblastoma].

OBJECTIVE: To evaluate the VMA/Cr and HVA/Cr of random urine in the diagnosis of neuroblastoma. METHODS: VMA/Cr and HVA/Cr were examined in 50 normal children and 11 cases of neuroblastoma (NB) aged 1 approximate, equals 5 years. The concentration of 4-hydroxy-3-methoxy-mandelic acid (VMA) and homovanillic acid (HVA) in random urine collection were analyzed by high-performance liquid chromatography and creatinine (Cr) analyzed by auto-biochemical analyzer. RESULTS: The normal range of VMA/Cr and HVA/Cr were <14.9 mmol/mol and <23.8 mmol/mol, respectively. The positive rate of VMA/Cr and HVA/Cr in NB patients was 90.9%. CONCLUSION: Determination of VMA/Cr and HVA/Cr in random urine collection can be used for NB diagnosis.
