This phase III trial studies how well active surveillance help doctors to monitor subjects with low risk germ cell tumors for recurrence after their tumor is removed. When the germ cell tumors has spread outside of the organ in which it developed, it is considered metastatic. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. The trial studies whether carboplatin or cisplatin is the preferred chemotherapy to use in treating metastatic standard risk germ cell tumors.

This phase III trial tests how well adding dinutuximab to induction chemotherapy along with standard of care surgery radiation and stem cell transplantation works for treating children with newly diagnosed high risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found in greater than normal amounts on some types of cancer cells. This helps cells of the immune system kill the cancer cells. Chemotherapy drugs such as cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, dexrazoxane, doxorubicin, temozolomide, irinotecan and isotretinoin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. During induction, chemotherapy and surgery are used to kill and remove as much tumor as possible. During consolidation, very high doses of chemotherapy are given to kill any remaining cancer cells. This chemotherapy also destroys healthy bone marrow, where blood cells are made. A stem cell transplant is a procedure that helps the body make new healthy blood cells to replace the blood cells that may have been harmed by the cancer and/or chemotherapy. Radiation therapy is also given to the site where the cancer originated (primary site) and to any other areas that are still active at the end of induction.
