OBJECTIVES:

• Define the antitumor effects of monoclonal antibody 3F8/sargramostim (3F8/GM-CSF) in patients with advanced neuroblastoma.
• Assess the biological effects of 3F8/GM-CSF in these patients.

OUTLINE: Patients receive monoclonal antibody 3F8 IV over 1.5 hours on days 0-4 and 7-11 and sargramostim (GM-CSF) IV over 2 hours on days -5 to 11. Treatment is repeated every 4 weeks for up to 4 courses in the absence of progressive disease, HAMA response, or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 11-40 patients will be accrued for this study over 4 years.

DISEASE CHARACTERISTICS:

• Neuroblastoma diagnosed by INSS criteria, i.e., either:

  • Histologic proof of disease OR
  • Tumor clumps in bone marrow plus elevated catecholamine levels

• Relapsed disease with poor long-term prognosis as indicated by at least one of the following:

  • N-myc amplification in tumor cells
  • Diploid chromosomal content in tumor cells
  • Distant skeletal metastases
  • Unresectable primary tumor crossing the midline
  • Bone marrow with greater than 10% tumor cells
• Documentation of measurable progressive disease or biopsy- proven stable disease at least 4 weeks after prior systemic therapy required
• No rapidly progressive disease
• Poor risk neuroblastoma (but without measurable disease) not eligible for other neuroblastoma protocols
