Standard Radiation Therapy, Higher-Dose Radiation Therapy, or Chemotherapy in Treating Older Patients...
Brain and Central Nervous System TumorsRATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in higher doses over a shorter period of time may kill more tumor cells and have fewer side effects. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether standard radiation therapy, higher-dose radiation therapy, or chemotherapy is more effective in treating older patients with glioblastoma multiforme. PURPOSE: This randomized phase III trial is studying standard radiation therapy to see how well it works compared with higher-dose radiation therapy or chemotherapy in treating older patients with glioblastoma multiforme.

High-Dose Methotrexate in Treating Young Patients With Solid Tumors
Brain and Central Nervous System TumorsSarcoma2 moreRATIONALE: Drugs used in chemotherapy, such as high-dose methotrexate work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Chemoprotective drugs, such as leucovorin calcium, may protect normal cells from the side effects of chemotherapy. PURPOSE: This phase I trial is studying the side effects, best way to give, and best dose of high-dose methotrexate in treating patients with solid tumors.

Enzastaurin in Treating Young Patients With Refractory Primary CNS Tumors
Brain and Central Nervous System TumorsNeuroblastomaRATIONALE: Enzastaurin may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase I trial is studying the side effects and best dose of enzastaurin in treating young patients with refractory primary brain tumors.

Everolimus, Temozolomide, and Radiation Therapy in Treating Patients With Newly Diagnosed Glioblastoma...
Brain and Central Nervous System TumorsRATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking some of the blood flow to the tumor. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving everolimus together with temozolomide and radiation therapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of everolimus when given together with temozolomide and radiation therapy in treating patients with newly diagnosed glioblastoma.

Tamoxifen, Carboplatin, and Topotecan in Treating Patients With CNS Metastases or Recurrent Brain...
Brain and Central Nervous System TumorsMetastatic Cancer2 moreRATIONALE: Drugs used in chemotherapy, such as carboplatin and topotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Tamoxifen may help carboplatin work better by making tumor cells more sensitive to the drug. PURPOSE: This phase II trial is studying the side effects of giving carboplatin and topotecan together with tamoxifen and to see how well it works in treating patients with central nervous system metastases or recurrent brain or spinal cord tumors.

Temozolomide in Treating Patients With Newly Diagnosed Anaplastic Oligodendroglioma or Mixed Oligoastrocytoma...
Central Nervous System TumorsBrain TumorRATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well temozolomide works in treating patients with newly diagnosed anaplastic oligodendroglioma or mixed oligoastrocytoma.

Radiation Therapy With or Without Temozolomide in Treating Older Patients With Newly Diagnosed Glioblastoma...
Brain and Central Nervous System TumorsRATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with temozolomide may kill more tumor cells. It is not yet known whether radiation therapy and temozolomide are more effective than radiation therapy alone in treating glioblastoma multiforme. PURPOSE: This randomized phase III trial is studying radiation therapy and temozolomide to see how well they work compared with radiation therapy alone in treating patients with newly diagnosed glioblastoma multiforme.

Adavosertib and Irinotecan Hydrochloride in Treating Younger Patients With Relapsed or Refractory...
Central Nervous System Embryonal Tumor With Rhabdoid FeaturesCentral Nervous System Embryonal Tumor15 moreThis phase I/II trial studies the side effects and best dose of adavosertib and irinotecan hydrochloride in treating younger patients with solid tumors that have come back (relapsed) or that have not responded to standard therapy (refractory). Adavosertib and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Durvalumab in Pediatric and Adolescent Patients
Solid TumorLymphoma1 moreThis clinical trial is the first clinical trial to study Durvalumab, a checkpoint inhibitor which stimulates the patient's own immune system to act against cancer cells in children and adolescents. This trial will assess the safety and tolerability of Durvalumab in children and adolescents and also study how Durvalumab is processed in their bodies.

Lapatinib and Paclitaxel in Treating Patients With Advanced Solid Tumors
Bladder CancerBrain and Central Nervous System Tumors7 moreRATIONALE: Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Lapatinib may help paclitaxel work better by making tumor cells more sensitive to the drug. Lapatinib may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving lapatinib together with paclitaxel may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of lapatinib when given together with paclitaxel in treating patients with advanced solid tumors.
