简要总结
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether radiation therapy alone is as effective as chemotherapy plus radiation therapy in treating germ cell tumor.
PURPOSE: This randomized phase III trial is studying radiation therapy alone to see how well it works compared to chemotherapy and radiation therapy in treating patients with newly diagnosed primary CNS germ cell tumor.
详细描述
OBJECTIVES:
Primary
- Compare event-free survival and overall survival of patients with newly diagnosed primary CNS germ cell tumor treated with conventional radiotherapy alone (regimen A) vs chemotherapy followed by tumor response-based radiotherapy (regimen B).
Secondary
- Determine the complete response rate in patients treated with regimen B.
- Determine the acute and subacute toxicity of regimen B in these patients.
- Compare treatment-related morbidity, in terms of verbal learning and memory, executive functioning, and quality of life, in patients treated with these regimens.
- Determine the prognostic value of baseline serum, lumbar, and intraventricular levels of human chorionic gonadotropin levels from patients treated with these regimens.
- Determine the prognostic value of extent of disease (M+ vs modified M+ vs M0) on event-free survival and overall survival of patients treated with these regimens.

研究组 & 干预措施
Regimen A (radiotherapy only)
Within 52 days of surgery, patients will undergo standard-dose radiation therapy 5 days a week for approximately 5-6 weeks.
干预措施: radiation therapy (Radiation)
Regimen B (chemotherapy plus radiotherapy)
Courses 1 and 2: Patients receive carboplatin IV over 1 hour on days 1 and 2 and etoposide IV over 2 hours on days 1-3. Treatment repeats every 21 days for 2 courses.
Within 3 weeks of completing chemotherapy, patients with CR undergo low-dose radiation therapy 5 days a week for 5 weeks. Patients with MRD, a PR, or SD receive chemotherapy courses 3 and 4 as outlined below.
Courses 3 and 4: Patients receive cisplatin IV over 6 hours on day 1, cyclophosphamide IV over 1 hour on days 2 and 3, and filgrastim (G-CSF), subcutaneous (SC) or IV beginning on day 4 and continuing until blood counts recover.
Treatment repeats every 21 days for 2 courses. Patients achieving a CR or MRD proceed to reduced-dose radiotherapy. Patients with a PR, SD, or progressive disease (PD) are restaged and may undergo standard radiation therapy as in regimen A.

主要结局
Event-free Survival
时间窗: Study enrollment until date of earliest qualifying event (QE), date last known to be QE-free if the patient is followed for less than three years and is QE-free at the time of analysis, or 3 years if the patient is QE-free at 3 years
Data will be summarized as number of patients in the following categories at the time of data cutoff for analyses of 3-year EFS: 1)Experienced a qualifying event (QE) (see below);2)Event-free through 3 years of follow-up;3)Event-free until data cutoff (if less than 3 years of follow-up);4)Withdrew from study;5)Lost to follow-up. QEs: 1)disease progression, defined as increase \>= 40% in tumor volume or \>= 25% in tumor area of target lesions;2)development of new lesions;3)occurrence of a second malignant neoplasm, defined as a malignancy with different histological type from trial-qualifying diagnosis;4)death from any cause. Stat. analyses will be based on time from enrollment to the earliest of: 1)occurrence of any of the QEs;2)withdrawal from study or lost to follow-up;3)completion of three years of follow-up event-free;4)data cutoff for completion of the statistical analyses for the protocol's primary objective.
