What was measured
Methotrexate plasma concentration-time data are collected after the start of methotrexate infusion in induction cycle 1. Population parameters and inter-subject variability are estimated. Individual estimates of methotrexate concentration at 42 hours post-dose are obtained using post hoc analysis.
Analysis population: Eligible patients who received methotrexate during induction cycle 1 and had samples collected for PK analysis.
Groups in this outcome
Low-Risk Group
Patients with gross total resection (GTR)/no evidence of metastatic disease (M0) medulloblastoma, nodular desmoplastic histology, or high grade glioma
Intermediate-Risk Group
Patients with no evidence of metastatic disease (M0) medulloblastoma or nodular desmoplastic histology with less than a gross total resection (GTR), other histologic diagnoses with no metastatic disease
High-Risk Group
Patients with central nervous system (CNS) metastatic disease
