Active clinical trials for "Central Nervous System Neoplasms"

RATIONALE: Diagnostic procedures, such as positron emission tomography using fluorothymidine F 18, may be effective in finding recurrent disease in patients with gliomas. PURPOSE: This clinical trial is studying how well positron emission tomography using fluorothymidine F 18 works in finding recurrent disease in patients with gliomas.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of different regimens of combination chemotherapy followed by peripheral stem cell transplantation in treating children who have newly diagnosed brain tumor.

This study will compare the overall survival (OS) time of elderly patients who would not tolerate standard chemotherapy for PCNSL treated with WBXRT together with Optune-TTF to those treated with whole-brain radiotherapy alone. Standard treatment of primary central nervous system lymphoma (PCNSL) for patients with good performance status involves high-dose methotrexate-based chemotherapy regimens and whole-brain radiation therapy (WBXRT). Although up to 20% of patients with PCNSL are 80 years of age or older, little data exist with regard to optimal treatment of this patient population and they often do not qualify for clinical trials. In addition, elderly patients have a poorer rate of complete and partial response and increased risk of toxicity when treated with standard chemotherapy regimens. Though a consensus does not exist, radiotherapy alone is often used in these patients to minimize toxic effects of more aggressive chemotherapies. The Optune TTF device has proven effective in treating high-grade gliomas and is currently being investigated to treat meningiomas and metastatic lesions in the brain as well as other tumor types elsewhere in the body. It is generally well tolerated with no known systemic side effects, producing only an occasional local skin reaction. The mechanism of action is independent of tumor type and therefore may be effective in treating lymphoma as well.

RATIONALE: Vaccines made from a person's cancer proteins may help the body build an effective immune response to kill cancer cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy together with GM-CSF may make a stronger immune response and kill more cancer cells. PURPOSE: This phase II trial is studying the side effects and how well giving vaccine therapy together with GM-CSF works in treating patients with CNS lymphoma.

RATIONALE: Collecting information on how craniopharyngioma is diagnosed and treated may help doctors predict a patient's response to treatment and help plan the best treatment. It may also help identify the intermediate- and long-term effects of treatment. PURPOSE: This clinical trial is collecting information on diagnosis, treatment, and quality of life of young patients who are undergoing surgery for craniopharyngioma.

RATIONALE: Drugs used in chemotherapy, such as temozolomide and topotecan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving temozolomide together with topotecan works in treating patients with primary CNS lymphoma.

RATIONALE: Immunotoxins can locate tumor cells and kill them without harming normal cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of immunotoxin therapy and to see how well it works in treating children undergoing surgery for recurrent or progressive malignant glioma.

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.

RATIONALE: Biological therapies, such as lymphokine-activated killer cells, may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as Gliadel wafer, 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 lymphokine-activated killer cells are more effective than Gliadel wafer in treating patients with glioblastoma multiforme. PURPOSE: This randomized phase II trial is studying the side effects and how well lymphokine-activated killer cells work compared with Gliadel wafer in treating patients with newly diagnosed glioblastoma multiforme that can be removed by surgery.

The purpose of this study is to determine whether [18F]FHBG is suitable for use as an imaging probe in cancer or rheumatoid arthritis patients enrolled in cell or gene therapy trials. In this phase 1 study we will assess the safety and biodistribution of [18F]FHBG in patients.
