Comparison of Radiation Therapy Regimens in Combination With Chemotherapy in Treating Young Patients With Newly Diagnosed Standard-Risk Medulloblastoma

A Study Evaluating Limited Target Volume Boost Irradiation and Reduced Dose Craniospinal Radiotherapy (18.00 Gy) and Chemotherapy in Children With Newly Diagnosed Standard Risk Medulloblastoma: A Phase III Double Randomized Trial

This randomized phase III trial is studying how well standard-dose radiation therapy works compared to reduced-dose radiation therapy in children 3-7 years of age AND how well standard volume boost radiation therapy works compared to smaller volume boost radiation therapy when given together with chemotherapy in treating young patients who have undergone surgery for newly diagnosed standard-risk medulloblastoma. Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy, such as vincristine, cisplatin, lomustine, and cyclophosphamide, work in different ways to stop tumor cells from dividing so they stop growing or die. Giving radiation therapy with chemotherapy after surgery may kill any remaining tumor cells. It is not yet known whether standard-dose radiation therapy is more effective than reduced-dose radiation therapy when given together with chemotherapy after surgery in treating young patients with medulloblastoma.

Study Overview

• Status: Active, not recruiting
• Conditions: Untreated Childhood Medulloblastoma
• Intervention / Treatment: Other: Laboratory Biomarker Analysis; Other: Quality-of-Life Assessment; Drug: Cisplatin; Drug: Cyclophosphamide; Drug: Vincristine Sulfate; Radiation: Craniospinal Irradiation; Radiation: Involved-Field Radiation Therapy; Drug: Lomustine; Radiation: Radiation Therapy

Detailed Description

PRIMARY OBJECTIVES:

I. Compare event-free survival (EFS) of pediatric patients (3 to 7 years of age) with newly diagnosed standard-risk medulloblastoma treated with standard-dose versus (vs.) reduced-dose craniospinal radiotherapy (SDCSI vs. LDCSI).

II. Compare EFS of patients (3-21 years of age) treated with standard-dose craniospinal radiotherapy and posterior fossa boost vs tumor bed boost radiotherapy in combination with this chemotherapy regimen.

SECONDARY OBJECTIVES:

I. Compare overall survival (OS) of pediatric patients (3-7 years of age) with newly diagnosed standard-risk medulloblastoma treated with SDCSI vs. LDCSI.

II. Compare OS of patients (3-21 years of age) with newly diagnosed standard-risk medulloblastoma treated with PFRT vs. IFRT.

III. To evaluate patterns of failure in patients treated with an irradiation boost volume smaller than conventional posterior fossa volumes.

IV. To reduce the cognitive, auditory, and endocrinologic effects of treatment of average-risk medulloblastoma by reducing the dose of craniospinal irradiation therapy.

V. To determine if the audiologic and endocrinologic toxicity will be reduced with the use of limited tumor boost volume irradiation compared to patients treated with conventional target volumes of radiation.

VI. Develop an optimal gene expression medulloblastoma outcome predictor, validated prospectively in a multi-institution randomized clinical trial.

VII. To improve compliance with long-term quality of life (QoL) and functional status data submission by educating institutional nurses to administer and submit for analysis a battery of four instruments (Behavior Assessment System for Children- 2nd Edition (BASC-2), Adaptive Behavior Assessment System - 2nd Edition (ABAS-II), Behavior Rating Inventory of Executive Function (BRIEF) and PedsQLTM 4.0).

OUTLINE: Patients 3-7 years of age are randomized to 1 of 4 arms (Arm I-IV). Patients 8-21 years of age are randomized to 1 of 2 arms (Arm V or VI).

Within 31 days after definitive surgery, all patients begin therapy. Patients undergo radiation therapy with doses according to their Arm randomization on days 1-5, 8-12, 15-19, 22-26, 29-33, 36-40, and 43-47 (weeks 0-6). All patients receive vincristine intravenously (IV) over 1 minute (or infusion via minibag as per institutional policy) on days 8, 15, 22, 29, 36, and 43 (weeks 1-6).

ARM I: Patients 3-7 years of age undergo lowered dose craniospinal irradiation (LDCSI) with involved-field radiation therapy (IFRT) boost.

ARM II: Patients 3-7 years of age undergo LDCSI with whole posterior fossa radiation therapy (PFRT) boost.

ARM III: Patients 3-7 years of age undergo standard dose craniospinal irradiation (SDCSI) with IFRT boost.

ARM IV: Patients 3-7 years of age undergo SDCSI with PFRT boost.

ARM V: Patients 8-21 years of age undergo SDCSI with IFRT boost.

ARM VI: Patients 8-21 years of age undergo SDCSI with PFRT boost.

MAINTENANCE CHEMOTHERAPY: Beginning 4 weeks after completion of chemoradiotherapy, patients receive 2 different regimens of maintenance chemotherapy for a total of 9 courses. Each course in regimen A is 6 weeks (42 days) in duration. Each course in regimen B is 4 weeks (28 days) in duration.

REGIMEN A (courses 1, 2, 4, 5, 7, and 8): Patients receive lomustine orally and cisplatin IV over 6 hours on day 1 and vincristine IV on days 1, 8, and 15 of weeks 11, 17, 27, 33, 43, and 49.

REGIMEN B (courses 3, 6, and 9): Patients receive cyclophosphamide IV over 1 hour on days 1 and 2 and vincristine IV on days 1 and 8 of weeks 23, 39, and 55.

Treatment continues in the absence of disease progression or unacceptable toxicity. Quality of life is assessed at 3-6 months after completion of radiotherapy and at 3-4 years after study entry. Neurocognitive function may also be assessed.

Patients are followed every 3 months for 1 year, every 6 months for 2 years, and then annually thereafter.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Event-free Survival (EFS)	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).	Assessed at 3 years
Overall Survival (OS)	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]).	3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Local Posterior Fossa (LPF) Failure Rate	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.	3 years
Non-local Posterior Fossa (NLPF) Failure Rate	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.	3 years
Non-posterior Fossa (NPF) Failure Rate	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.	3 years
Post-treatment Endocrine Function by CSI Group	Post-treatment endocrine function was measured by laboratory assessment of the thyroid stimulating hormone (TSH). The mean TSH will be reported.	Up to 3 years
Post-treatment Grade 3+ Hearing Loss as Measured by Common Terminology Criteria for Adverse Events (CTCAE) Version (v)4	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.	Up to 3 years
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).	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.	4 -15 months post diagnosis
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)	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.	27 - 48 months post diagnosis
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)	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.	49 - 72 months post diagnosis
Incidence of Grade 3+ Hearing Loss at 1-year Post Treatment as Assessed by CTCAE v4	Proportions of patients with grade 3+ hearing impairment as assessed by CTCAE v4 at 1-year post treatment were calculated.	Up to 3 years
Incidence of Endocrine Dysfunction as Measured by Growth Hormone Stimulation Tests at the Time of Completion of Therapy by Radiotherapy (RT) Group	Endocrine dysfunction was assessed by growth hormone stimulation (GHS) tests. We report the percentage of patients with abnormal growth hormone stimulation tests.	Post-treatment up to 3 years
Overall Survival (OS) by Molecular Subgroup Based on Methylation Arrays	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.	3 years
Progression-free Survival (PFS) by Molecular Subgroup Based on Methylation Arrays	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.	3 years
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)	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.	4 - 15 months post diagnosis
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)	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.	27-48 months post diagnosis
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)	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.	49 - 72 months post diagnosis
Compliance Rates for All Eligible and Evaluable Patients Enrolled Within Time Window 1 (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.	4-15 months post diagnosis
