Active Surveillance, Bleomycin, Etoposide, Carboplatin or Cisplatin in Treating Pediatric and Adult Patients With Germ Cell Tumors

Inclusion Criteria: * There is no age limit for the low risk stratum (stage I ovarian immature teratoma and stage I non-seminoma or seminoma malignant GCT \[all sites\]) * Standard risk 1: Patients must be \< 11 years of age at enrollment * Standard risk 2: Patients must be \>= 11 and \< 25 years of age at enrollment * Patients enrolling on one of the low risk arms must be newly diagnosed with a stage I germ cell tumor; for the standard risk arms, patients must be newly diagnosed with malignant germ cell tumor (stage II or higher). * Histologic confirmation of a primary extracranial germ cell tumor in any of the categories outlined below is required of all patients at enrollment , with the following exceptions: * Among patients were initially diagnosed with completely resected non-seminoma malignant GCT and later recur during observation post surgery, a diagnostic biopsy is not required for enrollment if elevated tumor markers rise to \> 5 x upper limit of normal (ULN) on at least 2 measurements taken at least 1 week apart. The pathology report of initial surgery should be provided * Patients may be enrolled without histologic or cytologic confirmation in the rare case where there are exceptionally raised tumor markers (alpha fetoprotein \[AFP- ≥ 500 ng/mL or HCG ≥ 500 IU/L) and radiologic features consistent with GCT. In addition, the treating clinician must deem that the patient's tumor is not suitable for upfront resection and that a biopsy is not in the patie…
