Imaging Procedure Using ALA in Finding Residual Tumor in Grade IV Malignant Astrocytoma
RATIONALE: Imaging procedures that use aminolevulinic acid (ALA) may help find and diagnose residual tumor in participants with grade IV malignant astrocytoma who are undergoing surgery to remove the tumor. PURPOSE: Our primary long-term goal is to improve the completeness of surgical resection of malignant brain tumor through image- guided fluorescence localization. We hypothesize that the use of qualitative fluorescence imaging and point PpIX concentration quantification will enable more complete tumor resection than normal direct (i.e., white light) visualization, and thereby improve participant survival.

Imaging Study of the Distribution of IL13-PE38QQR Infused Before and After Surgery in Adult Patients With Recurrent Malignant Glioma
The experimental anti-cancer drug IL13-PE38QQR, which is being developed for the treatment of malignant brain tumors, is composed of parts of two proteins: the immune system cytokine IL13 and a toxin from the bacterium Pseudomonas aeruginosa. The IL13 part of the drug binds to another protein, the IL13 receptor, when this receptor is displayed on the outside surface of cells. Cells with drug bound to the IL13 receptor take up the drug, and the toxin part of the drug then kills those cells. Since brain tumor cells display the IL13 receptor, they are potential targets that may be killed by this drug. This is a pilot study to visualize the distribution of IL13-PE38QQR infused into...

Imatinib Mesylate and Hydroxyurea in Treating Patients With Recurrent or Progressive Meningioma
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as hydroxyurea, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving imatinib mesylate together with hydroxyurea may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving imatinib mesylate together with hydroxyurea works in treating patients with recurrent or progressive meningioma.

Imatinib Mesylate and Temozolomide in Treating Patients With Malignant Glioma
RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 imatinib mesylate together with temozolomide may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of imatinib mesylate when given together with temozolomide in treating patients with malignant glioma.

Imatinib Mesylate in Treating Patients With Gliomas
RATIONALE: Imatinib mesylate may interfere with the growth of tumor cells and slow the growth of the tumor. PURPOSE: Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have gliomas.

Imatinib Mesylate in Treating Patients With Recurrent Malignant Glioma or Meningioma
RATIONALE: Imatinib mesylate may interfere with the growth of tumor cells and may be an effective treatment for recurrent glioma and meningioma. PURPOSE: Phase I/II trial to study the effectiveness of imatinib mesylate in treating patients who have progressive, recurrent, or unresectable malignant glioma or meningioma.

Imatinib Mesylate, Vatalanib, and Hydroxyurea in Treating Patients With Recurrent or Relapsed Malignant Glioma
RATIONALE: Imatinib mesylate, vatalanib, and hydroxyurea may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Vatalanib may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving imatinib mesylate and vatalanib together with hydroxyurea may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of imatinib mesylate and vatalanib when given together with hydroxyurea in treating patients with recurrent or relapsed malignant glioma.

Imetelstat Sodium in Treating Young Patients With Refractory or Recurrent Solid Tumors or Lymphoma
RATIONALE: Imetelstat sodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I clinical trial is studying the side effects and best dose of imetelstat sodium in treating young patients with refractory or recurrent solid tumors or lymphoma.

Immunological and Functional Characterization of Cellular Population CD45+ Infiltrating Human Glioblastoma
Despite advances in neurosurgery , radiotherapy and chemotherapy, the median survival in GBM patients is only 15 months from diagnosis. Immunotherapy by checkpoint inhibitors (PD1 /PDL-1) appears as a promising treatment for many cancers. However, first clinical results are disappointing for GBM. An hypothesis is the immunosuppressive activity from infiltrating non-tumor cells. Conversion of non-tumor cells from an immunosuppressive to an immuno-activating phenotype could be attempted in a therapeutic perspective.

Immunophenotyping From Blood of Patients With Malignant Gliomas
In this explorative study immunological changes during tumor therapy will be analyzed in patients with malignant glioma. Immunophenotyping before and during therapy is used as analysis method. Thereby immune cells are quantitatively and qualitatively detected from patient's blood at continuous time points. Additionally relevant mediators like cytokines, danger signals and chemokines are analyzed by other methods. Obtained results may give information about the effects of therapy on immunological processes and immune cells and may help to find immunological based predictive or prognostic tumor markers and to define time points for including additional immune therapy in the future.
