Surgery and Combination Chemotherapy in Treating Children With Extracranial Germ Cell Tumors
This phase III trial is studying surgery followed by combination chemotherapy to see how well it works in treating children with germ cell tumors that are not located in the head. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug, and giving them after surgery, may kill any remaining tumor cells following surgery. It is not yet known whether combination chemotherapy is effective in decreasing the recurrence of childhood germ cell tumors.

|Official Title:||A Phase III Study Of Reduced Therapy In The Treatment Of Children With Low And Intermediate Risk Extracranial Germ Cell Tumors|
- Event-free survival (EFS) of at least 92% (for intermediate-risk tumors only) defined as the first occurrence of relapse, progressive disease, second malignancy, or death after the start of protocol-specified chemotherapy [ Time Frame: Assessed up to 3 years ] [ Designated as safety issue: No ]A piecewise exponential failure rate model for the theoretical EFS time for both the low and intermediate risk patients will be used.
- Overall survival (OS) of at least 95% (both low-risk and intermediate-risk tumors) [ Time Frame: Assessed up to 4 years ] [ Designated as safety issue: No ]The model for OS will also be derived from a piecewise exponential failure rate model. The distribution of the complementary log-log transformation of the Kaplan-Meier estimate of the four-year survival will be used to calculate a 95% confidence interval for the true death rate.
- Days of hospitalization and number of doctor visits [ Time Frame: During treatment ] [ Designated as safety issue: No ]Calculated to quantify the treatment cost associated with this regimen.
- Toxicity as assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v4.0 [ Time Frame: During and after completion of study treatment ] [ Designated as safety issue: No ]The descriptions and grading scales found in the revised National Cancer Institute CTCAE v 4 will be used.

Experimental: Arm I
Patients receive cisplatin IV over 90 minutes and etoposide IV over 90 minutes on days 1-3 and bleomycin sulfate IV over ≥ 10 minutes on day 1. Treatment repeats every 3 weeks for 3 courses (weeks 0,3, & 6).
After completion of compressed induction chemotherapy, patients who have no change in disease status or disease progression are removed from study. Patients with no evidence of disease receive no further therapy. Patients with a partial response or who have abnormal tumor markers proceed to conventional surgery (second-look) and/or 3 more courses of compressed consolidation chemotherapy.
Patients undergo surgical resection of residual tumor. After surgery, patients who are in pathologic complete response and have normal tumor markers receive no further therapy. Patients who remain with a partial response after surgery receive compressed consolidation chemotherapy.
Patients receive cisplatin, etoposide, and bleomycin as in induction chemotherapy in weeks 10,13, & 16.
