- Brief Summary
STUDY DESIGN:
Prospective, non-randomised multicentre study with patients stratified according to risk groups INVESTIGATIONAL MEDICINAL PRODUCTS The IMPs on this trial are Carboplatin, Cisplatin, Ifosfamide and Etoposide (as approved by German competent authority).
PRIMARY OBJECTIVES:
Germinoma
* To maintain current high event-free survival (EFS) rates using a risk adapted approach
* In localised germinoma: to omit whole brain and spinal irradiation by using combined treatment with standard chemotherapy and ventricular irradiation (+/- boosts)
* In bifocal tumours (pineal + suprasellar): to treat as non-metastatic disease and to omit whole brain and spinal irradiation by using combined treatment with standard chemotherapy and ventricular irradiation (+/- boosts)
* In metastatic disease: to maintain current excellent EFS in metastatic germinoma with craniospinal irradiation Malignant non-germinoma
To improve EFS:
* by dose escalation of chemotherapy in patients identified as high risk at diagnosis ( age \< 6 years and/or AFP serum / CSF \> 1000 ng/ml)
* by standardising the surgical approach for residual disease after treatment Teratoma
* To register patients and collect data regarding diagnostics, treatment and outcome in order to develop future treatment strategies
SECONDARY OBJECTIVES:
Germinoma
* To minimise long term effects of irradiation by sparing spinal and whole brain radiotherapy in non-metastatic disease Malignant non-germinoma
* In standard risk to maintain EFS with chemotherapy and local irradiation Teratoma
* To evaluate the influence of surgery and treatment on outcome to assist in the development of a fu-ture treatment strategy For all histological subtypes
* To improve accuracy of diagnosis and staging in all registered patients
* To standardise neurosurgical intervention
* For all patients requiring biopsy or resection according to protocol guidelines, to collect and to store tumour material, and CSF where possible, for use in future biological studies.
ENDPOINTS / Criteria for evaluation:
Main end point
Event-free survival, defined as minimum time from the date of diagnosis to:
* Death from any cause
* Relapse
* Progressive disease on therapy
* Or second malignancy
Secondary end points
* Overall survival, defined as time to death from any cause, measured from the date of diagnosis
* Short and long term toxicity.
- Detailed Description
PATIENT POPULATION Age of patients: no lower or upper age limit; Estimated number: 400 malignant germ cell tumours
Diagnosis and main criteria for inclusion/exclusion:
Intracranial Germ Cell tumours of any histology and intracranial site and dissemination
Inclusion criteria
* Main residence in one of the participating countries
* Primary diagnosis of an intracranial germ cell tumour
* Written consent for trial participation, treatment according to the protocol and consent for data trans-fer
Exclusion criteria:
* Tumour entity other than primary intracranial germ cell tumour or CNS GCT as second malignancy

* Any treatment not given according to protocol prior to registration
TREATMENT:
GERMINOMA
Chemotherapy:
* Non-metastatic fully staged germinoma (± teratoma) Two courses (1 and 3) of Etoposide and Carboplatin, alternating with two courses (2 and 4) of Etoposide and Ifosfamide Note: Bifocal germinoma (pineal+suprasellar) are treated as non-metastatic germinoma, if stag-ing shows no additional dissemination
* Metastatic or incompletely staged germinomas (± teratoma) Do not receive chemotherapy in this protocol
Radiotherapy:
* Non-metastatic pure germinoma in PR/SD After Chemotherapy: 24 Gy (15 fractions) to whole ventricles with a 16 Gy (10 fraction) boost to tumour bed (total tumour dose 40 Gy)
* Non-metastatic germinoma in CR After Chemotherapy: 24 Gy (15 fractions) to whole ventricles
* Metastatic or incompletely staged pure germinoma 24 Gy (15 fractions) to craniospinal axis with a 16 Gy (10 fraction) boost to tumour bed and any intracranial metastases and spinal deposits (total tumour dose 40 Gy)
* Non-metastatic germinoma plus teratoma (incompletely resected) After Chemotherapy: 24 Gy (15 fractions) to whole ventricles; 30.4 Gy (19 fraction) boost to tumour bed (total tumour dose 54.4 Gy)
* Metastatic germinoma plus teratoma (incompletely resected) 24 Gy (15 fractions) to craniospinal axis ; 30.4 Gy (19 fraction) boost to tumour bed and 16 Gy (10 frac-tion) boost to metastases (total tumour dose 54.4 Gy)
NON-GERMINOMA (± TERATOMA)
Chemotherapy:
* Standard risk non-germinomatous malignant GCT Four courses of Etoposide, Cisplatin and Ifosfamide (standard treatment )
* High risk non-germinomatous malignant GCT Two courses of standard Etoposide, Cisplatin and Ifosfamide, followed by two dose intensified courses of Etoposide, Cisplatin and Ifosfamide with stem cell support
Resection of residual tumour after 3 courses chemotherapy (if indicated), followed by: 4th course. If vi-able cells are found in the resected tumour specimen patient is transferred to the high risk arm
Radiotherapy for standard and high risk non-germinomatous malignant GCT:
* Patients with localised disease at diagnosis After Chemotherapy: 54 Gy focal radiotherapy in 30 fractions
* Patients with metastatic disease at diagnosis After Chemotherapy: 30 Gy (20 fractions) to craniospinal axis with 24 Gy (15 fraction) boosts to tumour site and any intracranial metastases (total tumour dose 54 Gy) and 20.8 Gy (13 fraction) boosts to spinal deposits (total dose 50.8 Gy)
SPECIAL ASPECTS:
Central response evaluation on a national basis:
Germinoma: In all patients with localised germinoma a central national radiological review is mandatory for response evaluation to chemotherapy and decision if only ventricular irradiation or an additional tu-mour boost has to be performed.
Non-Germinoma: After three courses of chemotherapy to evaluate response to treatment and to deter-mine necessity of surgery in case of residual before radiotherapy.
