Dose Intensive Chemotherapy for Children Less Than Ten Years of Age Newly-Diagnosed With Malignant Brain Tumors: A Pilot Study of Two Alternative Intensive Induction Chemotherapy Regimens, Followed by Consolidation With Myeloablative Chemotherapy (Thiotepa, Etoposide and Carboplatin) and Autologous Stem Cell Rescue


OBJECTIVES:

- Investigate the toxicity of and response rate to an intensification of an induction
chemotherapy regimen (regimen A: cisplatin, vincristine, cyclophosphamide, and
etoposide) by incorporation of high-dose methotrexate with leucovorin calcium rescue in
patients with primitive neuroectodermal tumors and evidence of leptomeningeal
dissemination (M1, M2, or M3).

- Investigate the toxicity of and response rate to a new dose intensive induction
chemotherapy regimen (regimen C: vincristine, carboplatin, and temozolomide) in
children under ten years of age who are newly diagnosed with either high grade gliomas
or diffuse intrinsic pontine tumors. (Regimen B closed to accrual effective 3/30/2000;
regimen C open to accrual effective 7/21/2000)

- Investigate the feasibility of utilizing regimen C chemotherapy followed by
consolidation with myeloablative chemotherapy and autologous stem cell (either bone
marrow and/or peripheral blood) rescue in these patients. (Regimen B closed to accrual
effective 3/30/2000; regimen C open to accrual effective 7/21/2000)

- Investigate the toxicity of and response rate to an intensification of induction
regimen A chemotherapy by incorporation of high-dose methotrexate with leucovorin
calcium rescue in patients with primitive neuroectodermal tumors and evidence of
leptomeningeal dissemination (M1, M2, or M3).

- Estimate the time to disease progression and the pattern of relapse in patients who do
not have radiographic or cytologic evidence of residual disease at the time of
consolidation chemotherapy and who, therefore, do not receive post consolidation
irradiation.

- Estimate the time to disease progression and the pattern of relapse in patients who
have radiographic or cytologic evidence of residual disease at the time of
consolidation chemotherapy and who, therefore, receive post consolidation irradiation.

- Assess the morbidity and mortality of the consolidation chemotherapy regimen following
either regimen C or the intensified regimen A in these patients. (Regimen B closed to
accrual effective 3/30/2000; regimen C open to accrual effective 7/21/2000)

- Assess the impact that irradiation avoidance or the administration of reduced volume
craniospinal and/or focused field local irradiation has on neuropsychometric,
endocrinological functions, and physical growth.

OUTLINE: This is a two regimen study based on disease characteristics.

Patients in regimens A, B, and C undergo leukapheresis after receiving filgrastim (G-CSF) by
subcutaneous (SC) injections.

- Regimen A: Patients without evidence of neuraxis dissemination receive five 21 day
courses of the following chemotherapy: cisplatin IV over 6 hours on day 0; etoposide
and cyclophosphamide IV over 1 hour on days 1 and 2; vincristine IV on days 0, 7, and
14 of courses 1, 2, and 3; and G-CSF SC beginning on day 3 of each course and
continuing until blood counts recover or up to 48 hours before the start of the next
course. Patients with evidence of neuraxis dissemination also receive high-dose
methotrexate IV over 4 hours on day 3 and leucovorin calcium orally or by IV bolus
starting 24 hours prior to methotrexate and continuing every 6 hours until methotrexate
levels have diminished.

- Regimen B (closed to accrual effective 3/30/2000): Patients receive three 21-28 day
courses of the following chemotherapy: vincristine IV on days 0, 7, and 14 of each
course; carboplatin IV over 4 hours on days 3 and 4 of each course; oral procarbazine
daily on days 0-4; oral lomustine on days 3 and 4; and G-CSF SC daily beginning 24
hours following the last dose of carboplatin and continuing until blood counts recover
or up to 48 hours before the start of the next course. On day 7 of each course,
patients also receive peripheral blood stem cell (PBSC) reinfusion following
chemotherapy. Oral lomustine is administered only for the first two courses.

- Regimen C (open to accrual effective 07/21/2000): Patients receive four 28 day courses
of the following chemotherapy: carboplatin IV over 4 hours on days 0 and 1 of each
course; vincristine IV on days 0, 7, and 14 of the first three courses only; oral
temozolomide daily on days 0-4; and G-CSF SC daily beginning on day 5 and continuing
until blood counts recover.

After regimen A, B, or C and in the absence of disease progression, patients undergo
consolidation myeloablative chemotherapy by receiving carboplatin IV over 4 hours on days
-8, -7, and -6, and then thiotepa IV over 3 hours followed by etoposide IV on days -5, -4,
and -3. Patients with malignant gliomas or unbiopsied diffuse intrinsic pontine tumors do
not receive etoposide. On day 0, patients are reinfused with autologous PBSC. Following
recovery from consolidation chemotherapy, patients with radiographic or cytologic evidence
of residual disease undergo radiotherapy.

Patients are followed at 3 months, then every 3 months for the first 2 years, then every 6
months for years 2-4, and then annually thereafter.

PROJECTED ACCRUAL: Approximately 96 patients (73 for regimen A and 23 for regimen C) will be
accrued for this study. (Regimen B closed to accrual effective 3/30/2000.)
