14 Clinical Trials for Various Conditions
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Irinotecan may make tumor cells more sensitive to radiation therapy. Giving irinotecan together with whole-brain radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of irinotecan when given together with whole-brain radiation therapy and to see how well they work in treating patients with brain metastases from solid tumors. (The study of side effects and best dose has ended as of 4/15/05)
RATIONALE: Assessing the long-term effects of cancer treatment in cancer survivors may help improve the ability to plan effective treatment and follow-up care. PURPOSE: This clinical trial is studying the long-term effects of treatment in patients who were previously treated for childhood Hodgkin's lymphoma.
RATIONALE: Assessing the effects of methotrexate on brain function in children may improve the ability to plan treatment and decrease side effects. PURPOSE: Clinical trial to compare brain function of children who have been previously treated with methotrexate.
RATIONALE: Assessing the long-term effects of bone marrow transplant on lung function in patients may improve the ability to plan treatment. PURPOSE: This clinical trial studies lung function in pediatric patients who have undergone bone marrow transplant.
RATIONALE: Gathering information about how often metabolic syndrome occurs in young survivors of childhood leukemia who have undergone stem cell transplant may help doctors learn more about the disease and the long-term effects of leukemia treatment. It may also help improve the quality of life for future cancer survivors. PURPOSE: This clinical trial is studying metabolic syndrome in adolescent and young adult survivors of childhood leukemia who have undergone stem cell transplant.
RATIONALE: Gathering information about metabolic syndrome from young patients with acute lymphoblastic leukemia may help doctors learn more about the disease. PURPOSE: This phase I trial is studying the metabolic syndrome in young patients with acute lymphoblastic leukemia in remission.
RATIONALE: An educational and skills training program for the parent of a childhood cancer survivor with neurobehavioral dysfunction may help improve the child's school performance, thinking ability, and behavior. PURPOSE: This randomized clinical trial is studying an educational and skills training program for parents of childhood cancer survivors who have neurobehavioral dysfunction.
RATIONALE: Donepezil may decrease the side effects caused by radiation therapy to the brain. PURPOSE: This clinical trial is studying how well donepezil works in treating young patients with primary brain tumors previously treated with radiation therapy to the brain.
This clinical trial is looking at brain function in young patients receiving methotrexate for acute lymphoblastic leukemia. Learning about the long-term effects of methotrexate on brain function may help doctors plan cancer treatment.
RATIONALE: Comparing results of diagnostic procedures, such as ultrasound, done before, during, and after chemotherapy may help doctors learn about the side effects of chemotherapy and help plan the best treatment. PURPOSE: This clinical trial is studying ovarian damage in young premenopausal women undergoing chemotherapy for cancer.
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, etoposide phosphate, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Mannitol may help chemotherapy work better by making it easier for these drugs to get to the tumor. Chemoprotective drugs, such as acetylcysteine and sodium thiosulfate, may protect normal cells from the side effects of chemotherapy. Giving acetylcysteine together with mannitol, combination chemotherapy, and sodium thiosulfate may be an effective treatment for malignant brain tumors. PURPOSE: This phase I trial is studying the side effects and best dose of acetylcysteine when given together with mannitol, combination chemotherapy, and sodium thiosulfate in treating children with malignant brain tumors.
RATIONALE: Specialized radiation therapy that delivers radiation directly to the area where a tumor was surgically removed may kill any remaining tumor cells and cause less damage to normal tissue. PURPOSE: This phase II trial is studying how well proton beam radiation therapy works in treating young patients who have undergone biopsy or surgery for medulloblastoma or pineoblastoma.
RATIONALE: Cancer therapies may affect the ability of a child's brain and central nervous system to function normally. Learning to identify which patients will develop complications may improve the ability of doctors to plan cancer treatment and improve patient quality of life. PURPOSE: This clinical trial is studying neurobehavioral changes in children who have received steroid therapy or intrathecal therapy for acute lymphoblastic leukemia.
RATIONALE: Gathering information about metabolic syndrome from young patients who have survived acute lymphoblastic leukemia (ALL) may help doctors learn more about the disease. PURPOSE: This phase I trial is studying the metabolic syndrome in young patients who have survived acute lymphoblastic leukemia and in healthy sibling volunteers.
