Radiation Therapy (CR From Induction)
Patients will receive 6 cycles of Induction chemotherapy consisting of carboplatin and etoposide (Cycles 1, 3, and 5) alternating with ifosfamide and etoposide (Cycles 2, 4, and 6). The entire length of Induction is 18 weeks unless delay occurs due to myelosuppression or unanticipated toxicity. Each cycle of Induction will begin when ANC \> 750/L and platelets \> 75,000/L and when off filgrastim (G-CSF) for at least 48 hours. Following the Induction phase (weeks 0-18) those patient in CR will undergo radiation therapy. carboplatin: Given IV etoposide: Given IV ifosfamide: Given IV radiation therapy: craniospinal irradiation

PRIMARY outcome

Timeframe: 18 weeks

Population: Of the 102 eligible patients, 85 completed induction chemotherapy with sufficient data to assess response. Central review response assessment is used.

A patient who achieves a complete or partial response, defined a reduction of at least 65% in tumor size after induction chemotherapy will be considered to have experienced response.

SECONDARY outcome

Timeframe: At 3 years from study entry

Population: Two ineligible patients were excluded. A total of 102 eligible patients were analyzed.

Event-free Survival was defined as time from study entry to death from any cause, disease progression or recurrence, or second malignant neoplasm. Event-free survival was estimated by KM estimate.

SECONDARY outcome

Timeframe: At 3 years from study entry

Population: Two ineligible patients were excluded. A total of 102 eligible patients were analyzed. one patient died without the disease progression reported. But the death was due to the disease. The death was counted as "event" when progression-free survival (PFS) was calculated. So EFS and PFS at 3 years were same.

Progression-free Survival was defined as time from study entry to disease progression or recurrence. Deaths that are clearly unrelated to disease progression, and second neoplasms are censored in this analysis. Progression -free survival was estimated by KM estimate.
