RATIONALE: Drugs used in chemotherapy, such as carboplatin, etoposide, ifosfamide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving more than one drug (combination chemotherapy) with radiation therapy may kill more tumor cells.
PURPOSE: This phase III trial is studying combination chemotherapy followed by radiation therapy to see how well it works compared to radiation therapy alone in treating patients with germ cell tumors in the brain.
|Condition or disease||Intervention/treatment||Phase|
|Brain and Central Nervous System Tumors||Drug: carboplatin Drug: cisplatin Drug: etoposide phosphate Drug: ifosfamide Procedure: adjuvant therapy Procedure: conventional surgery Procedure: neoadjuvant therapy Radiation: radiation therapy||Phase 3|
- Evaluate and compare, in a non-randomized protocol, reduced-dose craniospinal radiotherapy alone or combination chemotherapy comprising carboplatin, etoposide phosphate, and ifosfamide and local irradiation in patients with intracranial germinoma.
- Increase survival with combination chemotherapy comprising cisplatin, etoposide phosphate, and ifosfamide followed by focal radiotherapy or craniospinal irradiation in patients with intracranial secreting germ cell tumors.
- Use the same diagnostic protocol for imaging and laboratory investigations before, during, and after treatment.
- Establish and use a common documentation system regarding general patient's data, including diagnostic tests, clinical evaluation, surgery, histology, radiotherapy, chemotherapy, and toxicity.
- Collect information about toxicity, prognostic factors, and tumor markers.
- Collect epidemiological data, including documentation of incidence and the site and the histologic pattern of intracranial secreting and nonsecreting germ cell tumors in children and adolescents.
- Register associated malformations in the patients as well as the epidemiology of tumors and malformations in relatives.
OUTLINE: This is a non-randomized, multicenter study. Patients are stratified according to tumor classification (pure CNS germinoma vs secreting germ cell tumor and embryonal carcinoma).
Patients in stratum I undergo biopsy or surgical resection and then begin radiotherapy with or without chemotherapy.
Stratum I (pure CNS germinoma [without elevated markers]): Patients receive 1 of 2 treatment options based on national/center standard:
- Option 1: Patients receive reduced-dose craniospinal radiotherapy 5 days a week for 3 weeks followed by a boost to the tumor bed 5 days a week for 2 weeks. Patients with multifocal or metastatic disease receive additional boosts to the tumor sites.
- Option 2: Patients receive carboplatin IV over 1 hour on day 1, etoposide phosphate IV over 1 hour on days 1-3 and 22-24, and ifosfamide IV over 3 hours on days 22-26. Treatment repeats every 6 weeks for 2 courses. After recovery from chemotherapy, patients undergo radiotherapy 5 days a week for 5 weeks.
- Stratum II (secreting tumors and embryonal carcinoma): Patients receive etoposide phosphate IV over 1 hour on days 1-3, cisplatin IV over 1 hour on days 1-5, and ifosfamide IV over 22 hours on days 1-5. Treatment repeats every 3 weeks for up to 4 courses. Patients whose tumor markers do not return to normal after completion of chemotherapy are off protocol. Patients may undergo surgery after chemotherapy course 2 or 4 if required. After completion of chemotherapy and recovery from surgery, patients with nonmetastatic disease undergo radiotherapy to the tumor bed 5 day a week for 6 weeks, and patients with metastatic disease undergo radiotherapy to the cerebrum, spinal axis, and tumor bed for 7 weeks.
After completion of study treatment, patients are followed for 4 weeks and then periodically.
PROJECTED ACCRUAL: Approximately 500 patients will be accrued for this study.
