What was measured

Proportions of patients with grade 3+ hearing loss after the completion of therapy will be calculated and reported separately for low dose craniospinal irradiation (LDCSI) versus (vs.) standard dose craniospinal irradiation (SDCSI) patients. Eligible and evaluable patients 3-7 years of age will be used.

Analysis population: Only eligible \& evaluable pts 3-7 years of age are included since only younger pts were randomized to either LD or SD CSI. 11 and 8 LDCSI and SDCSI pts respectively were not evaluable due to anaplastic disease or excess residual/disseminated disease, leaving 116 vs 110 patients for this analysis.

Groups in this outcome

Low-dose Craniospinal Radiation (LDSCI)

Includes eligible patients 3-7 years of age without anaplastic histology or evidence of disseminated or ERD based on central review and randomized to one of the LDCSI arms (Treatment Arms I or II)

Standard-dose Craniospinal Radiation (SDCSI)

Includes eligible patients 3-7 years of age without anaplastic histology or evidence of disseminated or ERD based on central review and randomized to one of the SDCSI arms (Treatment Arms III or IV)

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
