• Response rate after every 3 courses during treatment and then every 2-3 months for 1 year after completion of treatment [ Designated as safety issue: No ]
  

• Toxicity after every course during treatment [ Designated as safety issue: Yes ]
  

OBJECTIVES:

• Determine the response rates of patients with advanced neuroblastoma or other pediatric solid tumors treated with arsenic trioxide.
• Determine the toxicity of this drug in these patients.

OUTLINE: Patients are stratified according to type of disease (neuroblastoma with progressive disease vs neuroblastoma with stable refractory disease vs other solid tumor).

Patients receive arsenic trioxide IV over 1-4 hours on days 1-5 and 8-12. Treatment repeats every 28 days for a maximum of 6 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 2-3 months for 1 year and then annually thereafter.

PROJECTED ACCRUAL: A total of 45-120 patients (15-40 per stratum) will be accrued for this study.
