RATIONALE: AZD2171 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.
PURPOSE: This phase II trial is studying how well AZD2171 works in treating patients with recurrent glioblastoma multiforme.
- Determine the proportion of patients with recurrent glioblastoma multiforme (GM) who are alive and progression free 6 months after starting AZD2171 therapy.
- Assess the biological effect of AZD2171 by using the following MRI techniques: dynamic contrast-enhanced imaging; arterial spin-labeling imaging; perfusion-weighted imaging; and diffusion- tensor imaging at serial time points.
- Measure circulating endothelial and progenitor cells and plasma levels of tumstatin, (vascular endothelial growth factor (VEGF)-A and -D, sVEGF receptors, P1GF, platelet-derived growth factor (PDGF)-AA, PDGF-AB, PDGF-BB, Ang1, thrombospondin-1, and interleukin-8 as markers for response to antiangiogenic therapy in recurrent GM.
- Correlate treatment outcomes with pre-AZD2171 tumor specimens with respect to microvascular density, basement membrane and pericyte coverage, and angiopoietin-1 and -2 expression to determine whether these immunohistochemical analyses can be predictive of the response to AZD2171.
- Measure polymorphisms of kdr/flk-1 gene and genetic analysis of HIF1-alpha, TP53, and endothelial nitric oxide synthase genes in the archival tumor specimens.
- Determine the overall survival of patients with recurrent GM treated with AZD2171.
- Determine the radiographic response rate in patients with recurrent GM treated with AZD2171.
- Determine the safety of AZD2171 in this patient population.
OUTLINE: This is a multicenter study.
Patients receive oral AZD2171 once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for up to 12 months.
PROJECTED ACCRUAL: A total of 31 patients will be accrued for this study.

Hemangioblastomas (HBs) are benign vascular tumors of the central nervous system and histologically contain abundant microvessels. Therefore, they clinically exhibit vascular malformation-like charact...
Central nervous system (CNS) tumors are a group of neoplasms that originate from various cells in the CNS. The increasing incidence and prevalence of this type of tumor in developing countries are str...
The purpose of this study was to examine the prevalence and predictors of social difficulties in adolescent survivors of central nervous system (CNS) tumors.
Primary central nervous system lymphoma (PCNSL) is a rare disease. Studies of PCNSL in patients with rheumatic diseases are lacking. Neither clinical symptoms nor radiographic manifestation is specifi...
The lack of a standard treatment approach has contributed to poor outcomes of patients with recurrent central nervous system (CNS) mixed malignant germ cell tumors (MMGCT). There are no data in the li...
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant.

Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
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...
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
