Study type | Interventional |
Intervention(s) | Germinoma stratum Arm A1: 1)Chemotherapy: 4 cycles alternating CE regimen (carboplatin 560 mg/m2 day1, etoposide 150 mg/m2 day1-3) and PE regimen (cisplatin 90 mg/m2 day1, etoposide 150 mg/m2 day1-3). 2) Radiotherapy: whole brain or whole ventricular radiation according tumor location (1.8 Gy/day, 5 days/week, 13 times and 23.4 Gy in total) is introduced between first and second cycle start of chemotherapy. 3) Tumor removal: if the residual tumor is identified after chemotherapy and radiotherapy and can be removed safely, tumor removal is performed. Arm B1: 1) Chemotherapy: 4 cycles alternating CE regimen and PE regimen. 2) Radiotherapy: whole brain or whole ventricular radiation therapy according tumor location (1.8 Gy/day, 5 days/week, 10 times and 18 Gy in total) is introduced between first and second cycle start of chemotherapy. 3) Tumor removal: if the residual tumor is identified after chemotherapy and radiotherapy and can be removed safely, tumor removal is performed. Malignant germ cell tumor stratum Arm A2: 1) Chemotherapy: 5 cycles of PEC regimen (cisplatin 90 mg/m2 day1, etoposide 150 mg/m2 day1-3, cyclophosphamide 1g/m2 day1, 2). 2) Radiotherapy: craniospinal irradiation (1.8 Gy/day, 5 days/week, 13 times and 23.4 Gy in total) followed by local radiation therapy (1.8 Gy/day, 5 days/week, 17 times and 30.6 Gy in total) is introduced after chemotherapy. 3) Tumor removal: if a residual tumor is identified after chemotherapy and radiotherapy and can be removed safely, tumor removal is performed. Arm B2: 1) Chemotherapy: 5 cycles of PEC regimen. 2) Radiotherapy: local radiation therapy (1.8 Gy/day, 5 days/week, 30 times and 54 Gy in total) is introduced after chemotherapy. 3) Tumor removal: if the residual tumor is identified after chemotherapy and radiotherapy and can be removed safely, tumor removal is performed. 4) High dose chemotherapy (HDC): HDC (thiotepa 200 mg/ m2 day-12, -11, -5, -4, melphalan 70 mg/ m2 day-11, -5, -4, peripheral blood stem cell transplantation day 0) is performed in the residual tumor after chemotherapy, radiotherapy and tumor removal, viable malignant tumor component identified in the removed tumor. |
