OBJECTIVES: Primary * Determine the maximum tolerated dose of oral irinotecan when administered with fixed-dose temozolomide and cefixime in pediatric patients with recurrent or resistant high-risk neuroblastoma. * Determine the toxic effects of this regimen in these patients. Secondary * Determine the response rate in patients treated with this regimen. * Determine the pharmacokinetics of this regimen in these patients. * Correlate UGT1A1 genotype with the occurrence of dose-limiting diarrhea in patients treated with this regimen. * Correlate BCRP genotype with pharmacokinetic phenotype in patients treated with this regimen. * Correlate p53 status in tumor cells with response in patients treated with this regimen. OUTLINE: This is a multicenter, dose-escalation study of irinotecan. Patients receive oral cefixime once daily beginning 5 days before the start of fixed-dose temozolomide and irinotecan and continuing for the duration of the study. Patients also receive oral temozolomide once daily on days 1-5 and oral irinotecan once daily on days 1-5 and 8-12. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. A maximum of 12 patients are treated at the MTD. Patients are followed for toxicity, response, and survival. PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 1.25 years.
