- Event-free Survival (EFS) [ Time Frame: Assessed at 3 years ]EFS was defined as the time interval from date of study entry to date of disease progression, disease recurrence, second malignant neoplasm or death from any cause, whichever occurs first, or to the date of last follow-up for patients without events. EFS was estimated using the method of Kaplan and Meier. 3-year estimates are reported with 95% confidence intervals (CI's).
- Overall Survival (OS) [ Time Frame: 3 years ]OS was defined as the time interval from date of study entry to date of death from any cause or to the date of last follow-up for survivors. OS was estimated using the method of Kaplan and Meier. 3-year estimates are reported with 95% CI's. For purposes of this analysis, arms I, III and V (involved field radiation therapy [IFRT]) are combined and compared to arms II, IV and VI (posterior fossa irradiation [PFRT]).
- Local Posterior Fossa (LPF) Failure Rate [ Time Frame: 3 years ]LPF failure was defined as tumor recurrence/progression within the tumor bed. The cumulative incidence (CI) of LPF failure was estimated; 3-year estimates were reported with 95% confidence intervals. Patients with other failure types (e.g., NPF) and with other events prior to LPF failure (e.g., death, second malignancy) were considered as having competing events.
- Non-local Posterior Fossa (NLPF) Failure Rate [ Time Frame: 3 years ]NLPF failure was defined as tumor recurrence/progression outside the radiation therapy clinical target volume boost (CTV-boost) but within the posterior fossa CTV (CTV-PF). The cumulative incidence (CI) of NLPF failure was estimated; 3-year estimates were reported with 95% confidence intervals. Patients with other failure types (e.g., NPF, LPF) and with other events prior to NLPF failure (e.g., death, second malignancy) were considered as having competing events.
- Non-posterior Fossa (NPF) Failure Rate [ Time Frame: 3 years ]NPF failure was defined as tumor recurrence within the neuroaxis but outside the radiation therapy clinical target volume (CTV). The cumulative incidence (CI) of NPF failure was estimated; 3-year estimates were reported with 95% confidence intervals. Patients with other failure types (e.g., LPF failure) and with other events prior to NPF failure (e.g., death, second malignancy) were considered as having competing events.
- Post-treatment Endocrine Function by CSI Group [ Time Frame: Up to 3 years ]Post-treatment endocrine function was measured by laboratory assessment of the thyroid stimulating hormone (TSH). The mean TSH will be reported.
- Post-treatment Grade 3+ Hearing Loss as Measured by Common Terminology Criteria for Adverse Events (CTCAE) Version (v)4 [ Time Frame: Up to 3 years ]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.
- Post-treatment Neurocognitive Function as Measured by the Estimated Full-scale IQ (FSIQ) by CSI Group Within Time Window 1 (4 - 15 Months Post Diagnosis). [ Time Frame: 4 -15 months post diagnosis ]Post-treatment neurocognitive function was assessed. Full-scale IQ (FSIQ) is a representative measurement for neurocognitive function. FSIQ was measured by IQ tests. Assessments within the time window, from eligible and evaluable patients are reported. The time window is 4-15 months post diagnosis, only the assessments before progression date were reported. The Range of FSIQ is 50-150. A higher FSIQ is better.
- Post-treatment Neurocognitive Function as Measured by the Estimated Full-scale IQ (FSIQ) by CSI Group Within Time Window 2 (27 - 48 Months Post Diagnosis) [ Time Frame: 27 - 48 months post diagnosis ]Post-treatment neurocognitive function was assessed. Full-scale IQ (FSIQ) is a representative measurement for neurocognitive function. FSIQ was measured by IQ tests. Assessments within the time window, from eligible and evaluable patients are reported. The time window is 27-48 months post diagnosis, only the assessments before progression date were reported. The range of FSIQ is 50 - 150. A higher FSIQ is better.
- Post-treatment Neurocognitive Function as Measured by the Estimated Full-scale IQ (FSIQ) by CSI Group Within Time Window 3 (49 - 72 Months Post Diagnosis) [ Time Frame: 49 - 72 months post diagnosis ]Post-treatment neurocognitive function was assessed. Full-scale IQ (FSIQ) is a representative measurement for neurocognitive function. FSIQ was measured by IQ tests. Assessments within the time window, from eligible and evaluable patients are reported. The time window is 49-72 months post diagnosis, only the assessments before progression date were reported. The Range of FSIQ is 50-150. A higher FSIQ is better.
- Incidence of Grade 3+ Hearing Loss at 1-year Post Treatment as Assessed by CTCAE v4 [ Time Frame: Up to 3 years ]Proportions of patients with grade 3+ hearing impairment as assessed by CTCAE v4 at 1-year post treatment were calculated.
- Incidence of Endocrine Dysfunction as Measured by Growth Hormone Stimulation Tests at the Time of Completion of Therapy by Radiotherapy (RT) Group [ Time Frame: Post-treatment up to 3 years ]Endocrine dysfunction was assessed by growth hormone stimulation (GHS) tests. We report the percentage of patients with abnormal growth hormone stimulation tests.
- Overall Survival (OS) by Molecular Subgroup Based on Methylation Arrays [ Time Frame: 3 years ]OS was defined as the time interval from date of study entry to date of death from any cause or to date of last contact for survivors. OS was estimated using the method of Kaplan and Meier. 3-year estimates are reported with 95% CI's.
- Progression-free Survival (PFS) by Molecular Subgroup Based on Methylation Arrays [ Time Frame: 3 years ]PFS was defined as the time interval from date of study entry to disease progression, relapse or death due to cancer or to last follow-up. Second malignancies and deaths from causes clearly not associated with tumor progression or recurrence were censored. PFS was estimated using the method of Kaplan and Meier. 3-year estimates are reported with 95% CI's.
- Post-treatment Metacognition Index (MI) on the Behavior Rating Inventory of Executive Function (BRIEF) by CSI Group Within Time Window 1 (4-15 Months Post Diagnosis) [ Time Frame: 4 - 15 months post diagnosis ]Metacognition index (MI) was measured by BRIEF test. Assessments within the time window, from eligible and evaluable patients are reported. If the patient had disease progression, only the assessments before progression date were reported. The MI is a standard T- score, and it ranges from 0 to 100. The higher score reported suggests a higher level of dysfunction.
- Post-treatment Metacognition Index (MI) on the Behavior Rating Inventory of Executive Function (BRIEF) by CSI Group Within Time Window 2 (27-48 Months Post Diagnosis) [ Time Frame: 27-48 months post diagnosis ]Metacognition index (MI) was measured by BRIEF test. Assessments within the time window, from eligible and evaluable patients are reported. If the patient had disease progression, only the assessments before progression date were reported. The MI is a standard T- score, and it ranges from 0 to 100. The higher score reported suggests a higher level of dysfunction.
- Post-treatment Metacognition Index (MI) on the Behavior Rating Inventory of Executive Function (BRIEF) by CSI Group Within Time Window 3 (49 - 72 Months Post Diagnosis) [ Time Frame: 49 - 72 months post diagnosis ]Metacognition index (MI) was measured by BRIEF test. Assessments within the time window, from eligible and evaluable patients are reported. If the patient had disease progression, only the assessments before progression date were reported. The MI is a standard T- score, and it ranges from 0 to 100. The higher score reported suggests a higher level of dysfunction.
- Compliance Rates for All Eligible and Evaluable Patients Enrolled Within Time Window 1 (4-15 Months Post Diagnosis) [ Time Frame: 4-15 months post diagnosis ]Compliance rates are calculated to monitor the compliance with long-term quality of life and functional status data submission. A patient will be compliant if the patient has metacognition index score. Compliance rates will be assessed at each of the 3 neurocognitive/quality of life assessment time windows. All eligible and evaluable patients enrolled will be used. Patients removed from treatment prior to the time of neuropsychological assessment (for reasons such as disease progression, death, withdrawal of consent, etc.) will not be included in the denominator to assess the compliance rate. The time window is 4 - 15 months post diagnosis.
- Compliance Rates for All Eligible and Evaluable Patients Enrolled Within Time Window 2 (27-48 Months Post Diagnosis) [ Time Frame: 27-48 months post diagnosis ]Compliance rates are calculated to monitor the compliance with long-term quality of life and functional status data submission. A patient will be compliant if the patient has metacognition index score. Compliance rates will be assessed at each of the 3 neurocognitive/quality of life assessment time windows. All eligible and evaluable patients enrolled will be used. Patients removed from treatment prior to the time of neuropsychological assessment (for reasons such as disease progression, death, withdrawal of consent, etc.) will not be included in the denominator to assess the compliance rate. The time window is 27 - 48 months post diagnosis.
