What was measured

For patients treated in the intermediate and high risk strata with residual or metastatic disease we will estimate the stratum-specific objective response rate (complete response (CR) or partial response \[ PR\]). All patients who receive at least 1 -dose of methotrexate are evaluable for response. Objective responses must be sustained for at least eight weeks.

Analysis population: Eligible intermediate and high risk group patients who received at least 1 dose of methotrexate were included in this analysis. One of the high risk patients did not start therapy and was excluded.

Groups in this outcome

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
