| Purpose: |
|
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor
cells, either by killing the cells or by stopping them from dividing. A bone marrow or
peripheral stem cell transplant using stem cells from the patient may be able to replace
blood-forming cells that were destroyed by chemotherapy. This may allow more chemotherapy to
be given so that more tumor cells are killed.
PURPOSE: This phase III trial is studying how well giving combination chemotherapy with or
without etoposide followed by an autologous stem cell transplant works in treating young
patients with previously untreated malignant brain tumors.

OBJECTIVES:
Primary
- Determine the 2-year event-free survival (EFS) and overall survival (OS) of pediatric
patients with previously untreated nondisseminated medulloblastoma (< 4 years of age),
disseminated medulloblastoma (< 10 years of age), or noncerebellar primitive
neuroectodermal tumors (PNET) (disseminated or non-disseminated) treated with induction
chemotherapy followed by consolidation with myeloablative chemotherapy and autologous
hematopoietic stem cell rescue.
- Determine the toxicity of this regimen in these patients.
- Determine the mortality of patients treated with this regimen.
Secondary
- Determine the complete and partial response rates after completion of induction
chemotherapy in these patients stratified according to pathology (medulloblastoma vs
noncerebellar PNET vs high-grade gliomas vs atypical teratoid/rhabdoid tumors vs
choroid plexus carcinomas and atypical papillomas vs ependymomas).
- Describe the EFS and OS of these patients stratified according to additional diagnoses
(atypical teratoid/rhabdoid tumors vs choroid plexus carcinomas and atypical choroid
plexus papillomas vs ependymomas vs high-grade gliomas).
- Describe the time to progression and patterns of relapse in these patients stratified
by diagnosis and radiotherapy received (< 6 years of age with evidence of no residual
tumor pre-transplant and no post-transplant consolidation radiotherapy vs < 6 years of
age with residual tumor present pre-transplant treated with post-transplant
consolidation radiotherapy vs > 6 years of age treated with post-transplant
consolidation radiotherapy).
- Determine the neuropsychometric function, endocrinologic function, and physical growth
in these patients stratified according to radiotherapy received (none vs reduced-volume
craniospinal radiotherapy vs focused local-field radiotherapy).
OUTLINE: This is a pilot study. Patients are stratified according to type of tumor (nonglial
vs glial and diffuse pontine).
- Regimen C (patients with glial tumors):
- Stem cell harvesting (bone marrow and/or peripheral blood): Patients undergo
leukapheresis or bone marrow aspiration to collect bone marrow or peripheral blood
stem cells prior to beginning induction chemotherapy or after the first course of
induction chemotherapy.
- Induction chemotherapy: Patients receive vincristine IV on days 1, 8, and 15 of
courses 1-3, oral temozolomide once daily on days 1-5, and carboplatin IV over 4
hours on days 1 and 2. Patients also receive G-CSF SC beginning on day 6 and
continuing until blood counts recover. Treatment repeats every 28 days for 4
courses in the absence of disease progression or unacceptable toxicity.
Patients with unresectable bulky disease and corticosteroid dependence are removed from
study. All other patients proceed to consolidation chemotherapy.
- Consolidation chemotherapy: Patients receive carboplatin IV over 4 hours on days -8 to
-6 and thiotepa IV over 3 hours on days -5 to -3.
- Autologous bone marrow or peripheral blood stem cell transplantation: Patients undergo
reinfusion of bone marrow or peripheral blood stem cells on day 0. Patients also
receive G-CSF SC beginning on day 1 and continuing until blood counts recover.
- Radiotherapy: Beginning within 6 weeks after stem cell transplantation, patients > 6
years of age at diagnosis undergo radiotherapy once daily 5 days a week for 4-6 weeks
in the absence of disease progression or unacceptable toxicity. Patients ≤ 6 years of
age undergo radiotherapy if there is evidence of tumor remaining after completion of
induction chemotherapy.
- Regimen D2 (patients with nonglial tumors):
- Stem cell harvesting (bone marrow and/or peripheral blood): Patients undergo
leukapheresis or bone marrow aspiration to collect bone marrow or peripheral blood stem
cells prior to beginning induction chemotherapy or after the first course of induction
chemotherapy.
- Induction chemotherapy:
- Courses 1, 3, and 5 (28 days per course): Patients receive cisplatin IV over 6
hours on day 1, cyclophosphamide IV over 1 hour and etoposide IV over 2 hours on
days 2 and 3, high-dose methotrexate IV over 4 hours on day 4, and filgrastim
(G-CSF) subcutaneously (SC) beginning on day 5 and continuing until blood counts
recover. Patients also receive vincristine IV on days 1, 8, and 15 of courses 1
and 3.
- Courses 2 and 4 (28 days per course): Patients receive oral temozolomide once
daily on days 1-5, oral etoposide once daily on days 1-10, cyclophosphamide IV
over 1 hour on days 11 and 12, and G-CSF SC beginning on day 13 and continuing
until blood counts recover. Patients also receive vincristine IV on days 1, 8, and
15 of course 2.
Patients with unresectable bulky disease and corticosteroid dependence are removed from
study. All other patients proceed to consolidation chemotherapy.
- Consolidation chemotherapy: Patients receive carboplatin IV over 4 hours on days -8 to
-6 and thiotepa IV over 3 hours and etoposide IV over 3 hours on days -5 to -3.
- Autologous bone marrow or peripheral blood stem cell transplantation: Patients undergo
re-infusion of bone marrow or peripheral blood stem cells on day 0. Patients also
receive G-CSF SC beginning on day 1 and continuing until blood counts recover.
- Radiotherapy:Patients undergo radiotherapy as in regimen C. Patients in both regimens
undergo neuropsychological testing after induction chemotherapy but before
consolidation chemotherapy and then at 18, 36, and 54 months after completion of study
treatment. Neuropsychometric and neuroendocrine testing is performed before and after
radiotherapy. Quality of life is also assessed periodically.
After completion of study treatment, patients are followed periodically.
PROJECTED ACCRUAL: A total of 120 patients will be accrued for this study. |
