A Study Using Chemotherapy Followed by Radiation Therapy in Treating Younger Patients with Newly Diagnosed Localized Central Nervous System Germ Cell Tumors


About this study

Drugs used as chemotherapy, such as carboplatin, etoposide, and ifosfamide 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 chemotherapy with radiation therapy may kill more tumor cells. This phase II trial studies how well chemotherapy and radiation therapy work in treating younger patients with newly diagnosed central nervous system germ cell tumors.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.
