The purpose of this study is to learn about the safety and effectiveness of two different drug combinations in patients who have intermediate- and poor-risk germ cell tumors (GCT). One combination of drugs, paclitaxel, ifosfamide and cisplatin (TIP), is experimental. The other combination of drugs, bleomycin, etoposide and cisplatin (BEP), is the standard of care treatment for intermediate- and poor-risk germ cell tumors. However, BEP does not cure every patient and therefore newer treatments are needed.
