About
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving combination chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Sometimes, after surgery, the tumor may not need more treatment until it progresses. In this case, observation may be sufficient. It is not yet known which combination chemotherapy regimen given together with surgery, with or without autologous bone marrow or peripheral stem cell transplant, is more effective in treating newly diagnosed neuroblastoma.
PURPOSE: This phase III trial is studying combination chemotherapy to see which regimen given together with surgery, with or without autologous bone marrow or peripheral stem cell transplant, works in treating infants with newly diagnosed neuroblastoma.

OBJECTIVES:
Primary
Secondary
OUTLINE: This is a nonrandomized, multicenter study. Patients are assigned to 1 of 4 treatment regimens according to disease criteria. Patients who are not eligible for any of these regimens (stage 1 or resectable stage 2 disease) undergo surgical resection followed by observation.
Regimen NB 99.1 (unresectable stage 2 or 3): Patients are treated according to spinal cord involvement and presence of neurological symptoms.
Group I (no evidence of spinal cord involvement):
Group II (dumbbell tumors, spinal cord compression symptoms or life-threatening symptoms [e.g., respiratory obstruction]): Patients receive 2 courses of VP-CARBO therapy. Patients who achieve a response proceed to surgery or biopsy if the extraspinal portion is resectable. Patients with nonresponding disease or an unresectable extraspinal portion of the tumor receive 2 courses of CADO therapy and then undergo surgery or biopsy. Patients with dumbbell tumors but no spinal cord compression symptoms are treated as in group I.
Regimen NB 99.2 (stage 4S or stage 4 without bone, pleura/lung, or CNS metastases and no MYCN amplification): Patients who do not have severe or life-threatening symptoms are observed for spontaneous regression of disease. Patients with severe symptoms receive 1 course of VP-CARBO therapy. Patients with a Philadelphia score ≥ 2 (or ≥ 1 for neonates [< 1 month old]) receive a second course of VP-CARBO therapy. If disease does not respond to 2 courses of VP-CARBO therapy, patients receive up to 4 courses of CADO therapy. Treatment ceases after response is obtained. Surgery is allowed but not required.
Regimen NB 99.3 (skeletal bone, pleural, and/or CNS metastases, no MYCN amplification): Patients receive 2 courses of VP-CARBO therapy. Patients with responding disease receive 2 more courses and then proceed to surgery (if possible). Patients with disease progression or no response after the first 2 courses of VP-CARBO therapy and patients who do not experience metastatic complete response (CR) after 4 courses of VP-CARBO therapy receive up to 4 courses of CADO therapy. Patients proceed to surgery, if possible, after 2-4 courses of CADO therapy.
Regimen NB 99.4 (stages 2-4 disease with MYCN amplification): Patients receive 2 courses of VP-CARBO therapy followed by 2 courses of CADO therapy and then surgery (if not already performed). Patients receive filgrastim (G-CSF) subcutaneously for 5 days between the second course of CADO therapy and surgery. Patients also undergo collection of their bone marrow or peripheral blood stem cells (PBSC). Patients who undergo surgery receive 1 course of VP-CARBO therapy followed by 1 course of CADO therapy postsurgery. At least 3 weeks after the third course of CADO therapy, patients receive high-dose chemotherapy comprising busulfan every 6 hours on days -7 to -3 and melphalan IV on day -2 followed by autologous bone marrow or PBSC infusion on day 0. At least 2 months later, patients undergo radiotherapy to the primary tumor site, even if complete surgical resection has been accomplished. Patients with stage 4 disease who do not achieve metastatic CR after chemotherapy (before surgery) go off study.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 330 patients will be accrued for this study.
