Treatment for stage III-IV neuroblastoma patients: initial response to chemotherapy evaluated by biochemical parameters.

Author information

Division of Pediatrics, Children's Research Hospital, Kyoto, Japan.


Fourteen patients with stage III-IV neuroblastoma were treated with alternating combination chemotherapy consisting of (a) VP16/cisplatin and (b) doxorubicin/vincristine/cyclophosphamide. The initial response to induction chemotherapy, especially to VP16/cisplatin was evaluated by determining t 1/2 for urinary vanillylmandelic acid (VMA), homovanillic acid and serum neuron specific enolase (NSE). The period prior to normalization of these parameters was also determined. The patients could be classified as 7 rapid responders, with less than 3 weeks of t 1/2 VMA, or t 1/2 NSE, and 7 slow responders longer than 4 weeks of t 1/2 VMA. An analysis of the data indicates that an initial rapid response correlated with subsequent high complete response rate, but did not necessarily predict better prognosis in these patients.
