• For patients with solid tumors without known bone marrow involvement: * Peripheral absolute neutrophil count (ANC) >= 1000/mm^3 * Platelet count >= 100,000/mm^3 (transfusion independent, defined as not receiving platelet transfusions for at least 7 days prior to enrollment)
• Patients with known bone marrow metastatic disease will be eligible for study provided they meet the blood counts (may receive transfusions provided they are not known to be refractory to red cell or platelet transfusions); these patients will not be evaluable for hematologic toxicity
• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 ml/min/1.73 m^2 or a serum creatinine based on age/gender as follows: * Age: 1 to < 2 years; maximum serum creatinine (mg/dL): male 0.6; female 0.6 * Age: 2 to < 6 years; maximum serum creatinine (mg/dL): male 0.8; female 0.8 * Age: 6 to < 10 years; maximum serum creatinine (mg/dL): male 1; female 1 * Age: 10 to < 13 years; maximum serum creatinine (mg/dL): male 1.2; female 1.2 * Age: 13 to < 16 years; maximum serum creatinine (mg/dL): male 1.5; female 1.4 * Age: >= 16 years; maximum serum creatinine (mg/dL): male 1.7; female 1.4
