Etoposide and carboplatin in neuroblastoma: a French Society of Pediatric Oncology phase II study.
OBJECTIVE
A phase II study of etoposide (VP 16) and carboplatin (CBDCA) was performed in patients with metastatic neuroblastoma (NB). The aim of the study was to find an alternative treatment for induction with different toxicities than the VP 16/cisplatin (CDDP) combination.


METHODS
Forty-seven patients who were from 6 months to 16 years of age, with either relapsed (29) or primary resistant (18) NB, were included in a cooperative multicenter phase II study of the French Society of Pediatric Oncology (SFOP). The schedule consisted of 5 consecutive days of VP 16 100 mg/m2/d and CBDCA 160 mg/m2/d.


RESULTS
The response rate for the 39 assessable patients was 43%; there were four complete remissions and 13 partial remissions. Neither the status of the patients nor the total dose of CDDP that was received previously influenced response. Hematologic toxicity was marked and caused considerable delay between courses (median interval, 39 days). In these heavily pretreated patients, 16% had a more than 50% decrease in creatinine clearance and a 22% World Health Organization (WHO) grade 2 ototoxicity.


CONCLUSIONS
This VP 16/CBDCA combination deserves further evaluation for efficacy and toxicity in newly diagnosed patients, and the combination of both drugs should be considered for high-dose therapy with bone marrow transplantation.
