Gene Therapy in Treating Patients With Primary Brain Tumors
RATIONALE: Inserting the gene for herpes virus into a person's cells may improve the body's ability to fight cancer or make the cancer more sensitive to chemotherapy using antiviral drugs such as ganciclovir. PURPOSE: Phase I trial to study the effectivenesss of gene therapy in treating patients with primary brain tumors.

Gene Therapy in Treating Patients With Recurrent Malignant Gliomas
RATIONALE: Inserting the gene for adenovirus p53 into a person's tumor may improve the body's ability to fight cancer. PURPOSE: Phase I trial to study the effectiveness of gene therapy in treating patients who have recurrent malignant gliomas.

Gene Therapy in Treating Patients With Recurrent or Progressive Brain Tumors
RATIONALE: Inserting the gene for p53 into a person's brain cells may improve the body's ability to fight cancer. PURPOSE: Phase I trial to study the effectiveness of p53 gene therapy with SCH-58500 in treating patients who have recurrent, or progressive glioblastoma multiforme, anaplastic astrocytoma, or anaplastic mixed glioma that can be removed during surgery.

Genetically Modified Neural Stem Cells, Flucytosine, and Leucovorin for Treating Patients With Recurrent High-Grade Gliomas
This phase I trial studies the side effects and determines the best dose of genetically modified neural stem cells and flucytosine when given together with leucovorin for treating patients with recurrent high-grade gliomas. Neural stem cells can travel to sites of tumor in the brain. The neural stem cells that are being used in this study were genetically modified express the enzyme cytosine deaminase (CD), which converts the prodrug flucytosine (5-FC) into the chemotherapy agent 5-fluorouracil (5-FU). Leucovorin may help 5-FU kill more tumor cells. The CD-expressing neural stem cells are administered directly into the brain. After giving the neural stem cells a few days to spread...

Genetic Study in Patients Receiving Treatment for Hodgkin's Disease or Childhood Brain Tumor
RATIONALE: Determination of genetic markers for leukemia or non-Hodgkin's lymphoma that is secondary to Hodgkin's disease and childhood brain tumors may help doctors to identify patients who are at risk for these cancers. PURPOSE: Clinical trial to determine the presence of certain genes in patients who are receiving treatment for Hodgkin's disease or childhood brain tumors.

Gimatecan in Treating Patients With Recurrent or Progressive Primary Malignant Glioma
RATIONALE: Drugs used in chemotherapy, such as gimatecan, work in different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase I/II trial is studying the side effects and best dose of gimatecan in treating patients with recurrent or progressive primary malignant glioma.

Glasdegib (PF-04449913) With Temozolomide Newly Diagnosed Glioblastoma
Glioblastomas (GBMs) are the most common malignant primary brain tumors. Despite multimodality aggressive therapies (surgery followed by chemoradiotherapy based on TMZ and adjuvant TMZ), median overall survival is only 12 to 15 months. This dramatic behavior is mainly due to the high invasiveness and proliferation rate of GBM. In addition, GBM exhibits a high resistance to standard chemotherapy and radiotherapy. Current strategies for the treatment of GBM are only palliative, and include surgical resection (which is frequently incomplete due to the proximity of the tumour to vital brain structures) and focal radiotherapy. A large number of chemotherapeutic agents...

Gliadel Wafer and Fluorescence-Guided Surgery With 5-ALA Followed by Radiation Therapy And Temozolomide in Treating Patients With Primary Glioblastoma
RATIONALE: Drugs used in chemotherapy, such as Gliadel wafer and temozolomide, 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. Giving radiation therapy and temozolomide after surgery and Gliadel wafer may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying the side effects of fluorescence-guided surgery with 5-ALA given together with Gliadel wafer, followed by radiation therapy and temozolomide, in treating patients with primary glioblastoma.

Gliadel Wafer and O6-Benzylguanine in Treating Patients With Recurrent Glioblastoma Multiforme
RATIONALE: Drugs used in chemotherapy, such as Gliadel wafer and O6-benzylguanine, 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. PURPOSE: This phase II trial is studying how well giving Gliadel wafer together with O6-benzylguanine works in treating patients with recurrent glioblastoma multiforme.

Glioblastoma Multiforme (GBM) Proton vs. Intensity Modulated Radiotherapy (IMRT)
The goal of this clinical research study is to compare IMRT with IMPT in patients with glioblastoma. Researchers want to learn about cognitive side effects (mental status changes) that may occur, such as memory loss and impaired thinking. IMRT is the delivery of focused radiation therapy using photon beams and advanced computer planning to help shape the dose in order to give the highest possible dose to the tumor with the least dose to surrounding normal tissues. IMPT is also focused radiation therapy similar to IMRT, but it uses proton particles to deliver the radiation instead of photon beams. IMPT also uses advanced computer planning in order to shape the dose to the...
