This phase II trial investigates evolutionary inspired therapy in treating fusion positive rhabdomyosarcoma that is newly diagnosed and has spread to other places in the body (metastatic). Chemotherapy drugs, such as vinorelbine, vincristine sulfate, and actinomycin D, 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. Cyclophosphamide is used to decrease the body's immune response and may inhibit DNA replication and initiate cell death. This study is being done to determine which of 4 different therapeutic treatments will have the best chance of the disease not worsening or coming back.

This phase II/III trial aims to determine the type of chemotherapy that will benefit patients who have had surgery for their stage II or III colon cancer based on presence or absence of circulating tumor deoxyribonucleic acid (ctDNA). In ctDNA positive patients, this trial compares the effect of usual chemotherapy versus mFOLFIRINOX. In ctDNA negative patients, this trial compares the effect of usual chemotherapy versus ctDNA testing every 3 months to determine which approach might be better to prevent colon cancer from returning. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It works by damaging cells DNA and may kill cancer cells. Leucovorin is in a class of medications called folic acid analogs. It works by protecting healthy cells from the effects of chemotherapy medications while allowing chemotherapy agent to enter and kill cancer cells. Fluorouracil is in a class of medications called antimetabolites. It stops cells from making DNA and may slow or stop the growth of cancer cells. Capecitabine is in a class of medications called antimetabolites. It Is taken up by cancer cells and breaks down to a substance that kills cancer cells. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It works by stopping the growth of cancer cells. This trial may help doctors determine what kind of chemotherapy to recommend to colon cancer patients based on the presence or absence of ctDNA after surgery for colon cancer.

This phase III trial compares the effect of selumetinib versus the standard of care treatment with carboplatin and vincristine (CV) in treating patients with newly diagnosed or previously untreated low-grade glioma (LGG) that does not have a genetic abnormality called BRAFV600E mutation and is not associated with systemic neurofibromatosis type 1. Selumetinib works by blocking some of the enzymes needed for cell growth and may kill tumor cells. Carboplatin and vincristine are chemotherapy drugs that work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. The overall goal of this study is to see if selumetinib works just as well as the standard treatment of CV for patients with LGG. Another goal of this study is to compare the effects of selumetinib versus CV in subjects with LGG to find out which is better. Additionally, this trial will also examine if treatment with selumetinib improves the quality of life for subjects who take it.

This phase II trial studies how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) 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. This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).
