What was measured

These data are based on patient diaries. For children \<3 years of age, we will calculate the percentage of total scheduled doses each patient received per course for each of the oral maintenance courses and report the overall average number percentage of doses received per course across patients. If patients received all planned doses, their percentage would be 100%. If the average percentage was less than 75%, then feasibility would be in question.

Analysis population: Eligible patients less than 3 years of age (n=273) constituted the study population for this analysis; 167 of these patients started the first course of maintenance and were included in this analysis (50 low-risk, 87 intermediate-risk, and 30 high-risk patients).

Groups in this outcome

Low-Risk Group

Patients \<3 years of age with gross total resection (GTR)/no evidence of metastatic disease (M0) medulloblastoma, nodular desmoplastic or high grade glioma histology will receive induction chemotherapy and low-risk therapy.

Intermediate-Risk Group

Patients \<3 years of age with M0 medulloblastoma or nodular desmoplastic histology with less than a GTR, other histologic diagnoses with no metastatic disease, will receive induction chemotherapy and intermediate-risk therapy.

High-Risk Group

Patients \<3 years of age with central nervous system (CNS) metastatic disease will receive induction chemotherapy and high-risk therapy
