Filter by:The purpose of the study was to determine if treating a limited volume of normal tissue surrounding the tumor or tumor bed using conformal radiation therapy would achieve similar rates of disease control compared to standard radiation therapy. The study was also conducted to examine the effect of irradiation on neurological, endocrine and cognitive function.
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.
RATIONALE: 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. It is not yet known whether radiation therapy is more effective than temozolomide in treating gliomas. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to temozolomide in treating patients with gliomas.
The purpose of this study is to evaluate the sensitivity and specificity of "A-PROTEIN" levels in patients with brain tumors. A-PROTEIN levels will be analyzed both pre and post treatment. Levels in blood and/or cerebrospinal fluid (CSF) will be analyzed and correlated with the underlying diagnosis and outcome.
Studies have provided evidence that residual microscopic malignant cells in autologous bone marrow or blood stem cell grafts can contribute to posttransplant relapse. Researchers are currently exploring different methods in an attempt to purify or "purge" the stem cell product to minimize the risk of tumor contamination. The CD133+ antigen is a protein contained on or "expressed" on numerous cells in the human body including specific hematopoietic progenitor (blood forming) cells. However, this antigen is not expressed on certain cancer cells including neuroblastoma. A technique using the investigational CliniMACS cell sorting device has been developed in an effort to filter out only those stem cells that express this CD133+ antigen in order to infuse a hematopoietic stem cell product with no tumor contamination potential. The primary objective of this study is to establish safety of treating patients with a high dose chemotherapy regimen of Busulfan and Melphalan followed by autologous CD133+ hematopoietic stem cell support. Transplants recipients are expected to achieve engraftment as defined by an absolute neutrophil count of greater than or equal to 500/mm3 for three consecutive days by day 42-post infusion. Thus, safety of the treatment plan will be evaluated in terms of failure to engraft by this specific time period.
RATIONALE: Drugs used in chemotherapy, such as temozolomide, vincristine, and irinotecan, 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 I trial is studying the side effects and best dose of irinotecan when given together with temozolomide and vincristine in treating young patients with refractory solid tumors.
RATIONALE: 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. Radiation therapy uses high-energy x-rays to kill tumor cells. Vatalanib may stop the growth of tumor cells by blocking blood flow to the tumor. Giving temozolomide and radiation therapy together with vatalanib may kill more tumor cells. PURPOSE: This randomized phase I/II trial is studying the side effects and best dose of vatalanib when given together with temozolomide and radiation therapy and to see how well they work in treating patients with newly diagnosed glioblastoma multiforme.
RATIONALE: Radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody TNT-1/B (^131I MOAB TNT-1/B), can find tumor cells and carry tumor-killing substances to them without harming normal cells. This may be an effective treatment for glioblastoma multiforme. PURPOSE: This phase I trial is studying the side effects and best dose of ^131I MOAB TNT-1/B in treating patients with progressive or recurrent glioblastoma multiforme.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Erlotinib 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. It may also make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with erlotinib may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of erlotinib when given together with radiation therapy and to see how well they work in treating young patients with newly diagnosed glioma.
RATIONALE: Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. Giving photodynamic therapy after surgery may kill any remaining tumor cells. PURPOSE: This randomized clinical trial is studying two different light doses of photodynamic therapy using porfimer sodium to compare how well they work in treating patients who are undergoing surgery for recurrent malignant astrocytoma.
