A Pilot Study of Shortened Induction Chemotherapy for Children with High-Risk Neuroblastoma


Full Title

N9: Pilot Study of Novel Shortened Induction Chemotherapy for High-Risk Neuroblastoma


The purpose of this study is to assess a new combination of chemotherapy drugs as the first treatment for children newly diagnosed with neuroblastoma that has a high risk of returning after therapy. The treatment is abbreviated N9 and includes three different drug combinations given at three different times:

  • Cyclophosphamide, topotecan, and vincristine
  • Ifosfamide, carboplatin, and etoposide 
  • Cyclophosphamide, doxorubicin, and vincristine 

The number of different drugs in N9 may make it less likely that the cancer will become resistant to chemotherapy. In addition, researchers think that N9 may have fewer side effects than the usual treatment approach.
