This pilot early phase I trial studies the side effects of induction chemotherapy without granulocyte colony-stimulating factor (G-CSF) when treating participants with high-risk neuroblastoma. Drugs used in chemotherapy, such as topotecan, cyclophosphamide, cisplatin, etoposide, vincristine, and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Induction chemotherapy is usually followed by a drug called G-CSF (filgrastim or pegfilgrastim) to prevent side effects from the chemotherapy. Removing G-CSF following induction chemotherapy may help kill more tumor cells in participants with high-risk neuroblastoma.

PRIMARY OBJECTIVES:
I. To determine the safety and feasibility of administering induction chemotherapy for high risk neuroblastoma patients without routine G-CSF administration for supportive care.
SECONDARY OBJECTIVES:
I. To determine the incidence and duration of delay in chemotherapy administration due prolonged neutrophil recovery in patients undergoing induction chemotherapy for high-risk neuroblastoma without prophylactic G-CSF.
II. To determine the number of antibiotic days and hospital days due to fever and/or infection in patients undergoing induction chemotherapy for high-risk neuroblastoma without prophylactic G-CSF.
III. To determine the number of platelet transfusions in patients undergoing induction chemotherapy for high-risk neuroblastoma without prophylactic G-CSF.
IV. To describe the response rate following induction chemotherapy without prophylactic G-CSF for patients with high-risk neuroblastoma.
V. To describe caregiver burden in patients undergoing induction chemotherapy for high risk neuroblastoma.
OUTLINE:
Participants receive cyclophosphamide intravenously (IV) once daily (QD) over 30-60 minutes and topotecan IV QD over 30 minutes on days 1-5 of courses 1 and 2. Participants then receive cisplatin IV QD over 60 minutes on days 1-4 and etoposide IV QD over 90 minutes on days 1-3 of courses 3 and 5. Participants also receive cyclophosphamide IV QD over 6 hours on days 1-2, followed by doxorubicin IV QD over 15 minutes and vincristine IV QD on days 1-3 of courses 4 and 6. Courses repeat every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up periodically for up to 21 weeks.
