Gemcitabine, Paclitaxel and Oxaliplatin (GemPOx)
A Phase II Clinical Trial of Induction Chemotherapy Regimen Gemcitabine, Paclitaxel and Oxaliplatin (GemPOx) Followed by a Single Cycle of High Dose Chemotherapy (HDC) and Autologous Hematopoietic Stem Cell Rescue (AuHSCR) for Patients With Recurrent or Progressive Intracranial Germ Cell Tumors

Brief Summary
This study will look to see how well patients with relapsed or recurrent intracranial germ cell tumors respond to the new combination of chemotherapy (in induction)of Gemcitabine, Paclitaxel and Oxaliplatin (GemPOx) followed by consolidation chemotherapy and autologous stem cell rescue.

Eligibility Criteria
You may qualify if:
- ICGCT including pure germinoma and MMGCT.
- Patients with histologically proven germinoma and MMGCT, including endodermal sinus tumor (yolk sac tumor), embryonal carcinoma, choriocarcinoma and mixed germ cell tumor will be eligible for the study.
- Patients with mature/immature teratoma who have tumor marker elevations are eligible on this study.
- Patient with ONLY mature and/or immature teratoma are ineligible in the absence of the tumor marker elevations.
You may not qualify if:
- Patients with ICGCTs who are newly diagnosed are excluded from the study.
- Patients with the diagnosis of mature or immature teratoma in the absence of tumor marker elevations are excluded from the study.
- Patients who are pregnant or breastfeeding are excluded from the study.
- Patients who have received previously a high dose chemotherapy regimen and autologous transplant are excluded from this study.
- Patients who have received gemcitabine, oxaliplatin and/or paclitaxel are excluded from this study.
