RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Drugs used in chemotherapy, such as temozolomide, also work in different ways to kill tumor cells or stop them from growing. Giving bevacizumab together with temozolomide may be a better way to block tumor growth.
PURPOSE: This phase II trial is studying how well giving bevacizumab and temozolomide together works in treating older patients with newly diagnosed glioblastoma multiforme or gliosarcoma.
I. To estimate overall survival in elderly subjects treated with bevacizumab and temozolomide for newly diagnosed glioblastoma multiforme.
I. To estimate 12-months survival. II. To estimate progression free survival for 2 years or until progression is detected.
III. To investigate the safety and tolerability of bevacizumab/temozolomide in elderly patient with glioblastoma.
IV. To isolate DNA, RNA, and protein isolated from frozen and paraffinized archival tumor samples for evaluations such as immunohistochemical pathway profiling of VEGF-dependent angiogenic pathways, gene expression microarray, and MGMT promoter methylation status to define important molecule features of treatment response and especially age-related molecular expression.
Patients receive bevacizumab IV over 30-90 minutes every 2 weeks and oral temozolomide on days 1-5. Treatment repeats every 28 days for 24 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at least every 4 months.

Nonislet cell tumor hypoglycemia is rare. We highlight the diagnosis and treatment of recurrent severe hypoglycemia in a 49-year-old woman with malignant solitary fibrous tumor of the pleura (Doege-Po...
Evaluation of von Willebrand factor (VWF) multimeric distribution is useful for subclassification of von Willebrand disease (VWD). Multimer analysis has historically been a manual, labor-intensive lab...

Histological analysis is a morphological technique and an effective method for understanding the pathology of rheumatoid arthritis (RA). Here, we describe the processes of paraffin samples, including ...
In the current study we used contrast-enhanced T1 subtraction maps to test whether early changes in enhancing tumor volume are prognostic for overall survival (OS) in newly diagnosed GBM patients trea...
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
The analysis of an activity, procedure, method, technique, or business to determine what must be accomplished and how the necessary operations may best be accomplished.
A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables.
Works consisting of studies using a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of literature.
Body of knowledge related to the use of organisms, cells or cell-derived constituents for the purpose of developing products which are technically, scientifically and clinically useful. Alteration of biologic function at the molecular level (i.e., GENETIC ENGINEERING) is a central focus; laboratory methods used include TRANSFECTION and CLONING technologies, sequence and structure analysis algorithms, computer databases, and gene and protein structure function analysis and prediction.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
