Brain Neoplasms: 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.Infratentorial Neoplasms: Intracranial tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures. Primary tumors of this region are more frequent in children, and may present with ATAXIA; CRANIAL NERVE DISEASES; vomiting; HEADACHE; HYDROCEPHALUS; or other signs of neurologic dysfunction. Relatively frequent histologic subtypes include TERATOMA; MEDULLOBLASTOMA; GLIOBLASTOMA; ASTROCYTOMA; EPENDYMOMA; CRANIOPHARYNGIOMA; and choroid plexus papilloma (PAPILLOMA, CHOROID PLEXUS).Neoplasms, Neuroepithelial: Neoplasms composed of neuroepithelial cells, which have the capacity to differentiate into NEURONS, oligodendrocytes, and ASTROCYTES. The majority of craniospinal tumors are of neuroepithelial origin. (From Dev Biol 1998 Aug 1;200(1):1-5)Iothalamic Acid: A contrast medium in diagnostic radiology with properties similar to those of diatrizoic acid. It is used primarily as its sodium and meglumine (IOTHALAMATE MEGLUMINE) salts.Glioma: Benign and malignant central nervous system neoplasms derived from glial cells (i.e., astrocytes, oligodendrocytes, and ependymocytes). Astrocytes may give rise to astrocytomas (ASTROCYTOMA) or glioblastoma multiforme (see GLIOBLASTOMA). Oligodendrocytes give rise to oligodendrogliomas (OLIGODENDROGLIOMA) and ependymocytes may undergo transformation to become EPENDYMOMA; CHOROID PLEXUS NEOPLASMS; or colloid cysts of the third ventricle. (From Escourolle et al., Manual of Basic Neuropathology, 2nd ed, p21)Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Brain Chemistry: Changes in the amounts of various chemicals (neurotransmitters, receptors, enzymes, and other metabolites) specific to the area of the central nervous system contained within the head. These are monitored over time, during sensory stimulation, or under different disease states.Brain Injuries: Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.Brain Mapping: Imaging techniques used to colocalize sites of brain functions or physiological activity with brain structures.Pancreatic Neoplasms: Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).Neoplasms: New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Neoplasms, Cystic, Mucinous, and Serous: Neoplasms containing cyst-like formations or producing mucin or serum.Brain Edema: Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS). (From Childs Nerv Syst 1992 Sep; 8(6):301-6)Brain Stem: The part of the brain that connects the CEREBRAL HEMISPHERES with the SPINAL CORD. It consists of the MESENCEPHALON; PONS; and MEDULLA OBLONGATA.Brain Ischemia: Localized reduction of blood flow to brain tissue due to arterial obstruction or systemic hypoperfusion. This frequently occurs in conjunction with brain hypoxia (HYPOXIA, BRAIN). Prolonged ischemia is associated with BRAIN INFARCTION.Skin Neoplasms: Tumors or cancer of the SKIN.Neoplasms, Multiple Primary: Two or more abnormal growths of tissue occurring simultaneously and presumed to be of separate origin. The neoplasms may be histologically the same or different, and may be found in the same or different sites.Brain Abscess: A circumscribed collection of purulent exudate in the brain, due to bacterial and other infections. The majority are caused by spread of infected material from a focus of suppuration elsewhere in the body, notably the PARANASAL SINUSES, middle ear (see EAR, MIDDLE); HEART (see also ENDOCARDITIS, BACTERIAL), and LUNG. Penetrating CRANIOCEREBRAL TRAUMA and NEUROSURGICAL PROCEDURES may also be associated with this condition. Clinical manifestations include HEADACHE; SEIZURES; focal neurologic deficits; and alterations of consciousness. (Adams et al., Principles of Neurology, 6th ed, pp712-6)Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Kidney Neoplasms: Tumors or cancers of the KIDNEY.Neoplasms, Second Primary: Abnormal growths of tissue that follow a previous neoplasm but are not metastases of the latter. The second neoplasm may have the same or different histological type and can occur in the same or different organs as the previous neoplasm but in all cases arises from an independent oncogenic event. The development of the second neoplasm may or may not be related to the treatment for the previous neoplasm since genetic risk or predisposing factors may actually be the cause.Thyroid Neoplasms: Tumors or cancer of the THYROID GLAND.Adenocarcinoma, Mucinous: An adenocarcinoma producing mucin in significant amounts. (From Dorland, 27th ed)Myeloproliferative Disorders: Conditions which cause proliferation of hemopoietically active tissue or of tissue which has embryonic hemopoietic potential. They all involve dysregulation of multipotent MYELOID PROGENITOR CELLS, most often caused by a mutation in the JAK2 PROTEIN TYROSINE KINASE.Lung Neoplasms: Tumors or cancer of the LUNG.Neurons: The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.DNA, Neoplasm: DNA present in neoplastic tissue.Hypoxia, Brain: A reduction in brain oxygen supply due to ANOXEMIA (a reduced amount of oxygen being carried in the blood by HEMOGLOBIN), or to a restriction of the blood supply to the brain, or both. Severe hypoxia is referred to as anoxia, and is a relatively common cause of injury to the central nervous system. Prolonged brain anoxia may lead to BRAIN DEATH or a PERSISTENT VEGETATIVE STATE. Histologically, this condition is characterized by neuronal loss which is most prominent in the HIPPOCAMPUS; GLOBUS PALLIDUS; CEREBELLUM; and inferior olives.Blood-Brain Barrier: Specialized non-fenestrated tightly-joined ENDOTHELIAL CELLS with TIGHT JUNCTIONS that form a transport barrier for certain substances between the cerebral capillaries and the BRAIN tissue.Parotid Neoplasms: Tumors or cancer of the PAROTID GLAND.Cerebral Cortex: The thin layer of GRAY MATTER on the surface of the CEREBRAL HEMISPHERES that develops from the TELENCEPHALON and folds into gyri and sulchi. It reaches its highest development in humans and is responsible for intellectual faculties and higher mental functions.Cystadenoma: A benign neoplasm derived from glandular epithelium, in which cystic accumulations of retained secretions are formed. In some instances, considerable portions of the neoplasm, or even the entire mass, may be cystic. (Stedman, 25th ed)Neoplasms, Connective and Soft Tissue: Neoplasms developing from some structure of the connective and subcutaneous tissue. The concept does not refer to neoplasms located in connective or soft tissue.Liver Neoplasms: Tumors or cancer of the LIVER.Neoplasms, Plasma Cell: Neoplasms associated with a proliferation of a single clone of PLASMA CELLS and characterized by the secretion of PARAPROTEINS.Appendiceal Neoplasms: Tumors or cancer of the APPENDIX.Cystadenoma, Mucinous: A multilocular tumor with mucin secreting epithelium. They are most often found in the ovary, but are also found in the pancreas, appendix, and rarely, retroperitoneal and in the urinary bladder. They are considered to have low-grade malignant potential.Ovarian Neoplasms: Tumors or cancer of the OVARY. These neoplasms can be benign or malignant. They are classified according to the tissue of origin, such as the surface EPITHELIUM, the stromal endocrine cells, and the totipotent GERM CELLS.Neoplasms, Experimental: Experimentally induced new abnormal growth of TISSUES in animals to provide models for studying human neoplasms.Endocrine Gland Neoplasms: Tumors or cancer of the ENDOCRINE GLANDS.Gastrointestinal Neoplasms: Tumors or cancer of the GASTROINTESTINAL TRACT, from the MOUTH to the ANAL CANAL.Magnetic Resonance Spectroscopy: Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).Osteoradionecrosis: Necrosis of bone following radiation injury.Neoplasm Recurrence, Local: The local recurrence of a neoplasm following treatment. It arises from microscopic cells of the original neoplasm that have escaped therapeutic intervention and later become clinically visible at the original site.Translational Medical Research: The application of discoveries generated by laboratory research and preclinical studies to the development of clinical trials and studies in humans. A second area of translational research concerns enhancing the adoption of best practices.Awards and PrizesCellular Phone: Analog or digital communications device in which the user has a wireless connection from a telephone to a nearby transmitter. It is termed cellular because the service area is divided into multiple "cells." As the user moves from one cell area to another, the call is transferred to the local transmitter.Neuroma, Acoustic: A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2. (From Adams et al., Principles of Neurology, 6th ed, p673)Great BritainRadio Waves: Electromagnetic waves with frequencies between about 3 kilohertz (very low frequency - VLF) and 300,000 megahertz (extremely high frequency - EHF). They are used in television and radio broadcasting, land and satellite communications systems, radionavigation, radiolocation, and DIATHERMY. The highest frequency radio waves are MICROWAVES.

Expression of the naturally occurring truncated trkB neurotrophin receptor induces outgrowth of filopodia and processes in neuroblastoma cells. (1/10928)

We have investigated the effects of the truncated trkB receptor isoform T1 (trkB.T1) by transient transfection into mouse N2a neuroblastoma cells. We observed that expression of trkB.T1 leads to a striking change in cell morphology characterized by outgrowth of filopodia and processes. A similar morphological response was also observed in SH-SY5Y human neuroblastoma cells and NIH3T3 fibroblasts transfected with trkB.T1. N2a cells lack endogenous expression of trkB isoforms, but express barely detectable amounts of its ligands, brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT-4). The morphological change was ligand-independent, since addition of exogenous BDNF or NT-4 or blockade of endogenous trkB ligands did not influence this response. Filopodia and process outgrowth was significantly suppressed when full-length trkB.TK+ was cotransfected together with trkB.T1 and this inhibitory effect was blocked by tyrosine kinase inhibitor K252a. Transfection of trkB.T1 deletion mutants showed that the morphological response is dependent on the extracellular, but not the intracellular domain of the receptor. Our results suggest a novel ligand-independent role for truncated trkB in the regulation of cellular morphology.  (+info)

Transduction of glioma cells using a high-titer retroviral vector system and their subsequent migration in brain tumors. (2/10928)

The intracranial migration of transduced glioma cells was investigated in order to improve the treatment of malignant glioma by gene therapy using retroviral vectors. In this study, about half the volume of the tumor mass could be transduced in 14 days after only a single implantation of 3 x 10(5) retrovirus-producing cells into a tumor mass with a diameter of 5 mm. Moreover, we were able to follow the migration of glioma cells transduced by the lacZ-harboring retroviruses originating from the high-titer retrovirus-producing cells. Besides the importance of using a high-titer retroviral vector system, our results also indicate that the implantation site of the virus-producing cells and the interval between the implantation of the virus-producing cells and the subsequent administration of ganciclovir are important factors for the efficient killing of glioma cells.  (+info)

An improved method for the structural profiling of keratan sulfates: analysis of keratan sulfates from brain and ovarian tumors. (3/10928)

A previously developed method for the structural fingerprinting of keratan sulfates (Brown et al., Glycobiology, 5, 311-317, 1995) has been adapted for use with oligosaccharides fluorescently labeled with 2-aminobenzoic acid following keratanase II digestion. The oligosaccharides are separated by high-pH anion-exchange chromatography on a Dionex AS4A-SC column. This methodology permits quantitative analysis of labeled oligosaccharides which can be detected at the sub-nanogram ( approximately 100 fmol) level. Satisfactory calibration of this method can be achieved using commercial keratan sulfate standards. Keratan sulfates from porcine brain phosphocan and human ovarian tumors have been examined using this methodology, and their structural features are discussed.  (+info)

Synthesis and evaluation of [18F]1-amino-3-fluorocyclobutane-1-carboxylic acid to image brain tumors. (4/10928)

We have developed a new tumor-avid amino acid, 1-amino-3-fluorocyclobutane-1-carboxylic acid (FACBC), labeled with 18F for nuclear medicine imaging. METHODS: [18F]FACBC was prepared with high specific activity (no carrier added [NCA]) and was evaluated for its potential in tumor localization. A comparative study was performed for [18F]FACBC and [18F]2-fluorodeoxyglucose (FDG) in which the uptake of each agent in 9L gliosarcoma (implanted intracerebrally in Fisher 344 rats) was measured. In addition, the first human PET study of [18F]FACBC was performed on a patient with residual glioblastoma multiforme. Quantitative brain images of the patient were obtained by using a Siemens 921 47-slice PET imaging system. RESULTS: In the rat brain, the initial level of radioactivity accumulation after injection of [18F]FACBC was low (0.11 percentage injected dose per gram [%ID/g]) at 5 min and increased slightly to 0.26 %ID/g at 60 min. The tumor uptake exhibited a maximum at 60 min (1.72 %ID/g), resulting in a tumor-to-brain ratio increase of 5.58 at 5 min to 6.61 at 60 min. In the patient, the uptake of [18F]FACBC in the tumor exhibited a maximum concentration of 146 nCi/mL at 35 min after injection. The uptake of radioactivity in the normal brain tissue was low, 21 nCi/mL at 15 min after injection, and gradually increased to 29 nCi/mL at 60 min after injection. The ratio of tumor to normal tissue was 6 at 20 min after injection. The [18F]FACBC PET scan showed intense uptake in the left frontal region of the brain. CONCLUSION: The amino acid FACBC can be radiofluorinated for clinical use. [18F]FACBC is a potential PET tracer for tumor imaging.  (+info)

Spontaneous pinealoma in a male Crj:CD (SD) IGS rat. (5/10928)

A pinealoma (benign) was found in a 61-week-old male Crj:CD (SD) IGS rat. The neoplasm was located between the cerebral hemispheres and the cerebellum. Histologically, the tumor cells consisted of two cell types: large, pale-staining cells and small dark-staining cells. A fibrovascular stroma divided the tumor cells into incomplete lobules or nest structures. Relatively numerous mitoses were noted in the tumor cells. Ultrastructurally, the tumor cells contained dense-cored vesicles, approximately 120 nm in diameter.  (+info)

Inhibition of angiogenesis induces chromaffin differentiation and apoptosis in neuroblastoma. (6/10928)

Inhibition of angiogenesis has been shown to reduce tumor growth, metastasis, and tumor microvascular density in experimental models. To these effects we would now like to add induction of differentiation, based on biological analysis of xenografted human neuroblastoma (SH-SY5Y, WAG rnu/rnu) treated with the angiogenesis inhibitor TNP-470. Treatment with TNP-470 (10 mg/kg s.c., n = 15) reduced the tumor growth by 66% and stereological vascular parameters (Lv, Vv, Sv) by 36-45%. The tumor cell apoptotic fraction increased more than threefold, resulting in a decrease in viable tumor cells by 33%. In contrast, the mean vascular diameter (29 microm) and the mean tumor cell proliferative index (49%) were unaffected. TNP-470-treated tumors exhibited striking chromaffin differentiation of neuroblastoma cells, observed as increased expression of insulin-like growth factor II gene (+88%), tyrosine hydroxylase (+96%), chromogranin A, and cellular processes. Statistical analysis revealed an inverse correlation between differentiation and angiogenesis. It is suggested that by inhibiting angiogenesis, TNP-470 induces metabolic stress, resulting in chromaffin differentiation and apoptosis in neuroblastoma. Such agonal differentiation may be the link between angiostatic therapy and tumor cell apoptosis.  (+info)

Expression and tissue localization of membrane-type 1, 2, and 3 matrix metalloproteinases in human astrocytic tumors. (7/10928)

Three different membrane-type matrix metalloproteinases (MT1-, MT2-, and MT3-MMPs) are known to activate in vitro the zymogen of MMP-2 (pro-MMP-2, progelatinase A), which is one of the key MMPs in invasion and metastasis of various cancers. In the present study, we have examined production and activation of pro-MMP-2, expression of MT1-, MT2-, and MT3-MMPs and their correlation with pro-MMP-2 activation, and localization of MMP-2, MT1-MMP, and MT2-MMP in human astrocytic tumors. The sandwich enzyme immunoassay demonstrates that the production levels of pro-MMP-2 in the anaplastic astrocytomas and glioblastomas are significantly higher than that in the low-grade astrocytomas (P<0.05 and P<0.01, respectively), metastatic brain tumors (P<0.05), or normal brains (P<0.01). Gelatin zymography indicates that the pro-MMP-2 activation ratio is significantly higher in the glioblastomas than in other astrocytic tumors (P<0.01), metastatic brain tumors (P<0.01), and normal brains (P<0.01). The quantitative reverse transcription polymerase chain reaction analyses demonstrate that MT1-MMP and MT2-MMP are expressed predominantly in glioblastoma tissues (17/17 and 12/17 cases, respectively), and their expression levels increase significantly as tumor grade increases. MT3-MMP is detectable in both astrocytic tumor and normal brain tissues, but the mean expression level is approximately 50-fold lower compared with that of MT1-MMP and MT2-MMP in the glioblastomas. The activation ratio of pro-MMP-2 correlates directly with the expression levels of MT1-MMP and MT2-MMP but not MT3-MMP. In situ hybridization indicates that neoplastic astrocytes express MT1-MMP and MT2-MMP in the glioblastoma tissues (5/5 cases and 5/5 cases, respectively). Immunohistochemically, MT1-MMP and MT2-MMP are localized to the neoplastic astrocytes in glioblastoma samples (17/17 cases and 12/17 cases, respectively), which are also positive for MMP-2. In situ zymography shows gelatinolytic activity in the glioblastoma tissues but not in the normal brain tissues. These results suggest that both MT1-MMP and MT2-MMP play a key role in the activation of pro-MMP-2 in the human malignant astrocytic tumors and that the gelatinolytic activity is involved in the astrocytic tumor invasion.  (+info)

Early induction of angiogenetic signals in gliomas of GFAP-v-src transgenic mice. (8/10928)

Angiogenesis is a prerequisite for solid tumor growth. Glioblastoma multiforme, the most common malignant brain tumor, is characterized by extensive vascular proliferation. We previously showed that transgenic mice expressing a GFAP-v-src fusion gene in astrocytes develop low-grade astrocytomas that progressively evolve into hypervascularized glioblastomas. Here, we examined whether tumor progression triggers angiogenetic signals. We found abundant transcription of vascular endothelial growth factor (VEGF) in neoplastic astrocytes at surprisingly early stages of tumorigenesis. VEGF and v-src expression patterns were not identical, suggesting that VEGF activation was not only dependent on v-src. Late-stage gliomas showed perinecrotic VEGF up-regulation similarly to human glioblastoma. Expression patterns of the endothelial angiogenic receptors flt-1, flk-1, tie-1, and tie-2 were similar to those described in human gliomas, but flt-1 was expressed also in neoplastic astrocytes, suggesting an autocrine role in tumor growth. In crossbreeding experiments, hemizygous ablation of the tumor suppressor genes Rb and p53 had no significant effect on the expression of VEGF, flt-1, flk-1, tie-1, and tie-2. Therefore, expression of angiogenic signals is an early event during progression of GFAP-v-src tumors and precedes hypervascularization. Given the close similarities in the progression pattern between GFAP-v-src and human gliomas, the present results suggest that these mice may provide a useful tool for antiangiogenic therapy research.  (+info)

A metastatic, or secondary, brain tumor is one that begins as cancer in another part of the body. Some of the cancer cells may be carried to the brain by the blood or lymphatic fluid, or may spread from adjacent tissue. The site where the cancerous cells originated is referred to as the primary cancer. Metastatic brain tumors are often referred to as lesions or brain metastases. Metastatic brain tumors are the most common brain tumors. There has been an increase in metastatic lesions as people are surviving primary cancers for longer periods of time ...

Series Editor: Arthur T. Skarin, MD, FACP, FCCP Systemic cancer can affect the central nervous system in several different ways, including direct tumor metastasis and indirect remote effects. Intracranial metastasis can involve the skull, dura, and leptomeninges (arachnoid and pia mater), as well as the brain parenchyma. Of these, parenchymal brain metastases are the most common and have been found in as many as 24% of cancer patients in autopsy studies. It has been reported that metastatic brain tumors outnumber primary brain tumors 10 to 1. To read the full article in PDF: Click here ...
Side Effects of Whole Brain Radiation. The initial approach to using radiation postoperatively to treat brain metastases, used to be whole brain radiation, but this was abandoned because of the substantial neurological deficits that resulted, sometimes appearing a considerable time after treatment. Whole brain radiation was routinely administered to patients after craniotomy for excision of a cerebral metastasis in an attempt to destroy any residual cancer cells at the surgical site. However, the deleterious effects of whole brain radiation, such as dementia and other irreversible neurotoxicities, became evident. This raised the question as to whether elective postoperative whole brain radiation should be administered to patients after excision of a solitary brain metastasis. Current clinical practice, at most leading cancer centers, use a more focused radiation field that includes only 2-3cm beyond the periphery of the tumor site. This may involve therapy once a day for about six weeks and ...
2814 An estimated 30% of breast cancer patients have metastases to the brain and no effective treatment is yet available. Breast cancer brain metastases flourishes under the brains highly vascularized microenvironment, which provides nutrients and oxygen to the tumor. The purpose of this study was to analyze the functional properties of endothelial cells derived from metastatic breast cancer to the brain (BBEC). BBEC were isolated from brain tissue specimens of a patient with advanced breast cancer brain metastases. Primary cultures of human BBEC were purified using flow cytometry and characterized as endothelial cells based on positive immunostaining for Factor VIII, CD31, and CD105. BBEC are morphologically larger and more flattened than normal brain endothelial cells (BEC). A functional analysis of BBEC demonstrate that these cells proliferate more slowly than the BEC, and exhibit a significantly higher expression of the proangiogenic growth factors: vascular endothelial growth factor ...

Pediatric brain tumors are abnormal growths that arise in the brain during childhood. Several treatment options are available, including close observation, surgery, radiation therapy and chemotherapy. Although brain tumors are rare overall, they are the most common solid tumor among children. Whats important to remember is that children are not simply miniature adults. Brain tumors in children behave differently than brain tumors in adults. Whats more, children require treatment that is tailored not just to their tumor type, but also to their age and development. At the Pediatric Neurosurgery Center, we are committed to meeting the special needs of young patients and their families. Pediatric brain tumors can be either benign or malignant. Malignant, or cancerous, tumors tend to be fast-growing and aggressive, invading surrounding brain tissue. Benign tumors are not cancerous; they do not spread and they tend to be slow-growing. Even slow-growing benign brain tumors can eventually become ...

A brain tumor is an abnormal growth of tissue in the brain. The tumor can either originate in the brain itself (primary brain tumor), or come from another part of the body and travel to the brain (metastastic or secondary brain tumor). Brain tumors may be classified as either benign (noncancerous) or malignant (cancerous), depending on their behavior.. A benign tumor does not contain cancer cells and usually, once removed, does not recur. Most benign brain tumors have clear borders, meaning they do not invade surrounding tissue. These tumors can, however, cause symptoms similar to cancerous tumors because of their size and location in the brain.. Malignant brain tumors contain cancer cells. Malignant brain tumors are usually fast growing and invade surrounding tissue. Malignant brain tumors very rarely spread to other areas of the body, but may recur after treatment. Sometimes, brain tumors that are not cancer are called malignant because of their size and location, and the damage they can do to ...

These deficits can be very disruptive for a persons daily functioning, quality of life and treatment compliance. Examining functional connectivity patterns during the performance of a cognitive task may enhance our understanding of the relationship between functional brain networks and cognitive performance. Despite the similarity in network topology across rest and task states, there are also meaningful differences in functional connectivity that are likely to be linked to cognitive performance. Currently, it is largely unknown how differences between rest and task functional connectivity patterns are related to cognitive functioning in ...

Additional studies demonstrated that the therapeutic ...
Los Angeles - March 22, 2006 - In a study published in the March 15 issue of The Journal of Immunology, researchers at Board of Governors Gene Therapeutics Research Institute at Cedars-Sinai Medical Center have developed a way to overcome immune privilege in the brain to eradicate potentially deadly brain tumors such as glioblastoma multiforme and other types of brain infections.. Brain tumors account for 85 to 90 percent of all primary central nervous system tumors. Of those tumors, almost 40 percent are either the deadly glioblastoma multiforme or anaplastic astrocytomas. Each year about 19,000 people in the United States are diagnosed with primary brain cancers, and close to 70 percent of those diagnosed will not survive more than five years. In addition, approximately 150,000 Americans a year are diagnosed with metastatic brain tumors, cancer that has spread into the brain from another part of the body.. "We have developed a novel gene therapy strategy to modify the brain microenvironment ...

Munich, February 3, 2017-In support of World Cancer Day 2017, which aims to bring global attention to cancer, Brainlab, a leader in cancer-fighting technologies, raises awareness about metastatic brain cancer and the revolutionary new methods being used to treat the disease. According to the World Health Organization (WHO), 14 million new cases of cancer are diagnosed every year, with that number expected to rise by 70% over the next two decades. Cancers of the lung, breast, skin, colon and kidney present the highest risk of metastasizing to the brain.. As treatments improve, in combination with early detection, cancer patients are living longer, resulting in higher incidence of brain metastases, according to the American Brain Tumor Association (ABTA). One of the most prevalent procedures for treating multiple brain metastases is whole brain radiation therapy (WBRT) despite increasing evidence that WBRT can lead to significant cognitive side effects and the existence of alternative, less severe ...
Brain is used for almost every function of the body. It is related to the work of most of the parts. It controls and coordinates the actions and allows us to think and feel. It processes information that is received from different parts of the body and the way how we react is dependent on brain only. It is considered as the most complex organ in the body. It consists of billions of neurons which are connected by synapses to several other neurons. There are some conditions and disorders related to this part which stops it from working properly and affect the whole body. Brain tumor is one of those conditions. Brain tumor treatment hospital in India diagnoses the symptoms and treats according to the severity of the condition.. It is the condition in which there is growth of abnormal cells or mass in the brain. Tumors are of different types. They can either be benign which means they are non cancerous or can be malignant which means they have the potential to spread to different parts of the body. ...

This neurosurgeon and neuroradiologist team will determine whether a new non-invasive MRI imaging technique can reveal innate immune cells presence in deadly brain tumors in children and adults, and can be used to assess responses to an experimental immunotherapy that is soon to undergo human clinical testing. Prognoses for malignant brain tumors in children and adults remain stubbornly poor, with a life expectancy of about one year, despite decades of vigorous research on experimental treatments. Prior research has demonstrated that innate (first line of defense) immune cells called "macrophages" infiltrate brain tumors; in fact, they make up 30-70 percent of brain tumor tissue. The degree of macrophage infiltration has been found to relate to overall survival in a few types of cancers including breast cancers and Hodgkins lymphoma, and in a type of brain tumor called malignant-astrocytoma. Despite the abundant macrophage presence in brain tumors, no current immunotherapy has employed the use ...

Management of patients with newly diagnosed malignant primary brain tumors with a focus on the evolving role of temozolomide Mark R Gilbert1, Terri S Armstrong21Department of Neuro-Oncology, The University of Texas MD, Anderson Cancer Center, Houston, TX, USA; 2Department of Integrated Nursing Care, University of Texas Science Center â School of Nursing, Houston, TX, USAAbstract: The prognosis for patients with newly diagnosed malignant gliomas remains poor; however there have been some recent advances in treatment that have generated optimism. Medical management usually includes administration of corticosteroids to control peritumoral edema. Anticonvulsants are indicated for patients with established tumor-related seizures; however, the prophylactic use of anticonvulsants remains controversial. Advances in neurosurgical techniques have improved the safety of tumor resection and most patients undergo the maximal safe surgical debulking of tumor. The tissue sample obtained provides conclusive
Brain metastases (BM) from hepatocellular carcinoma (HCC) are extremely rare and are associated with a poor prognosis. The aim of this study was to define clinical outcome and prognostic determinants in patients with BM from HCC. Between January 1994 and December 2009, all patients with HCC and BM treated in Sun Yat-sen University Cancer Center were retrospectively reviewed. Univariate and multivariate survival analyses were performed to identify possible prognostic factors. Forty-one patients were diagnosed with BM from HCC, an incidence of 0.47%. The median age at diagnosis of BM was 48.5 years. Thirty-three patients (80.5%) developed extracranial metastases at diagnosis of BM, and 30 patients (73.2%) had hepatitis B. Intracranial hemorrhage occurred in 19 patients (46.3%). BM were treated primarily either with whole brain radiation therapy (WBRT; 5 patients), stereotactic radiosurgery (SRS; 7 patients), or surgical resection (6 patients). The cause of death was systemic disease in 17 patients and

metastatic brain tumors are malignant.. - Primary brain tumors - gliomas. About 80% of primary malignant brain tumors known as gliomas.It is not any particular type of cancer, but the term is used to describe tumors that arise from glial cells (glia or glial cells - These cells surround nerve cells and play a supportive role, glial cells, except microglia have common features and some common origin,they constitute microenvironment specific to neurons, providing conditions for the transmission of nerve impulses).Glial cells are the building blocks of the connective tissue or supporting cells in the central nervous system (CNS).. gliomas are divided into four classes, which reflect the degree of malignancy.Classes (degree) I and II are considered low-grade, and classes III and IV - full-fledged.Classes I and II - with the slowest and least malignant.Class III malignant tumors and is considered to grow at a moderate rate.Class IV malignant - tumor such as glioblastoma, the most rapidly growing and ...
Treatment depends on the size and type of the tumor, from where in the body it spread, and the persons general health. The goals of treatment may be to relieve symptoms, improve functioning, or provide comfort.. Radiation to the whole brain is often used to treat tumors that have spread to the brain, especially if there are many tumors.. Surgery may be used when there is a single tumor and the cancer has not spread to other parts of the body. Some tumors may be completely removed. Tumors that are deep or that extend into brain tissue may be reduced in size (debulked).. Surgery may reduce pressure and relieve symptoms in cases when the tumor cannot be removed.. Chemotherapy for metastatic brain tumors is usually not as helpful as surgery or radiation. Some types of tumors, though, do respond to chemotherapy.. Stereotactic radiosurgery may also be used. This form of radiation therapy focuses high-power x-rays on a small area of the brain. It is used when there are only a few tumors.. Medicines ...

Our observed effect may have a correlation to the initial size of the lesion, as those with complete response had median initial size of 0.8 cm, while partial responders and stable responders had median initial sizes of 1.0 cm and 1.1 cm, respectively. In our descriptive comparison to patients treated with SRS and concurrent ipilimumab or with SRS without immunotherapy, the responses to SRS and pembrolizumab appeared favorable. Past studies have suggested that concurrent checkpoint blockade with CTLA-4 inhibition and SRS to brain metastases has durable local control of treated lesions [4, 5, 7], though not all reports have shown an enhanced benefit to SRS with concurrent ipilimumab [6]. In this study, we found that 93% of treated lesions were controlled at the time of death after SRS and concurrent pembrolizumab, similar to the prior reports of durable control.. Overall, pembrolizumab and brain radiation therapy appeared to have acceptable acute toxicity. Specific acute toxicities that were ...

The intracranial compartment is a common site of metastatic cancer. Of the patients projected to die of systemic cancer approximately 25 percent, or over are expected to have intracranial metastasis. The importance of intracranial metastasis is, however, not primarily due to its frequent occurrence but to the fact that the large majority of the new foci become symptomatic. Compared with other organs, such as the lung and liver, in which the incidence of metastasis is even higher, the manifestations of metastases affecting the brain are usually more overt and disabling and if untreated, tend to be rapidly lethal. For these reasons brain metastasis demands prompt diagnostic and therapeutic attention.. A sense of frustration is justifiably inherent in the treatment of patients suffering from disseminated cancer. With few exceptions, even the eradication of a presumed solitary metastasis is followed sooner or later by the discovery of metastases elsewhere or at the primary site. Nevertheless, ...
Glioblastoma multiforme (GBM), a highly malignant primary brain tumor, is difficult to distinguish from from its surrounding functioning tissue under direct vision in the operating field, since it grows in an infiltrative growth pattern. The main challenge in the surgical treatment of GBM is to fully resect the tumor and avoid neurological impairment. In this paper we extend previous proof-of-principle studies by extending the clinical potential of OTP with the introduction of more sophisticated multivariate analysis schemes. The aim is to distinguish tumor and healthy tissue as well as possible using singular value decomposition (SVD) and cluster analysis methods.. ...

Objective: Glioma is the most common primary malignant brain tumor in adults, responsible for 75% of adult primary malignant brain tumors, yet aside from its association with ionizing radiation, its etiology is poorly understood. Sex differences in brain tumor incidence suggest that hormonal factors may play a role in the etiology of these tumors, but few studies have examined this association in

BACKGROUND: Microglia/macrophages (M/Ms) with multiple functions derived from distinct activation states are key surveillants maintaining brain homeostasis. However, their activation status and role during the brain metastasis of malignant tumors have been poorly characterized. METHODS: Heterozygous CX3CR1-GFP transgenic mice were used to visualize the dynamic changes of M/Ms during the development of experimental brain metastasis through long-term intravital imaging equipped with redesigned bilateral cranial windows. The occurrence of experimental brain metastasis was evaluated after M/Ms were depleted with PLX3397, a CSF-1R inhibitor. The possible mediators of M/Ms in facilitating the brain metastasis were determined using reverse transcription-PCR, immunofluorescence, correlational analysis, and MMP inhibition. RESULTS: Here, we showed that M/Ms were persistently activated and facilitated the formation of melanoma brain metastasis in vivo. We observed that M/Ms gradually and massively ...

24 Feb 2016. A new report published in the journal Neuro-Oncology and funded by the American Brain Tumor Association (ABTA) finds that malignant brain tumours are the most common cause of cancer-related deaths in adolescents and young adults aged 15-39 and the most common cancer occurring among 15-19 year olds.. The 50-page report, which utilised data from the Central Brain Tumor Registry of the United States (CBTRUS) from 2008-2012, is the first in-depth statistical analysis of brain and central nervous system (CNS) tumours in adolescents and young adults (AYA).. Statistics are provided on tumour type, tumour location and age group (15-19, 20-24, 25-29, 30-34 and 35-39) for both malignant and non-malignant brain and CNS tumours.. When analysing data in 5-year age increments, researchers discovered that the adolescent and young adult population is not one group but rather several distinct groups that are impacted by very different tumour types as they move into adulthood, said Elizabeth ...
The virus enters into the brain without the immune system even recognizing it. Thats because the genetically engineered bug doesnt normally infect humans. But when rapidly dividing cells - such as cancer cells associated with brain tumors - are present, the virus known as Toca 511 starts churning out an enzyme that is a precursor to the battle to come and an advance that could transform how aggressive brain tumors are treated. "I was looking to attack a very difficult clinical problem, and there are few diseases that have been as difficult as malignant brain tumors," explains Dr. Michael Vogelbaum, a neurosurgeon in the Cleveland Clinics Burkhardt Brain Tumor and Neuro-Oncology Center since 1999. "This is the perfect match of my research and clinical interests.".

Childhood brain tumours have some of the longest time to diagnosis. A timely diagnosis may have a role in reducing anxiety in waiting for a diagnosis and subsequent morbidity and mortality. We investigated where the opportunities for an earlier diagnosis were, and for which anatomical locations this strategy will most likely to be effective.A record-linkage cohort study of patients diagnosed aged 0-24 years with a primary intracranial tumour between 1989 and 2006 in England, using records from the National Cancer Registry linked to hospital admission records from Hospital Episode Statistics (HES, 1997-2006) and primary care consultation records from Clinical Practice Research Datalink (CPRD, 1989-2006). Relevant neurological presentations were extracted from HES and CPRD. Temporal changes in presentation rates were estimated in generalised additive models.Frequency of presentation began to increase six months before diagnosis in primary care and three months before diagnosis in hospital.

While new targeted treatments developed across the past two decades have led to dramatic survival improvements for women with HER2-positive metastatic breast cancer, University of North Carolina Lineberger Comprehensive Cancer Center researchers and collaborators report that rates of breast cancer brain metastasis for women with this disease have not substantially declined.
Brain tumors are the second most common group of childhood cancers, accounting for about 20%-25% of all pediatric tumors. Deregulated expression of the MYC family of transcription factors, particularly c-MYC and MYCN genes, has been found in many of these neoplasms, and their expression levels are often correlated with poor prognosis. Elevated c-MYC/MYCN initiates and drives tumorigenesis in many in vivo model systems of pediatric brain tumors. Therefore, inhibition of their oncogenic function is an attractive therapeutic target. In this review, we explore the roles of MYC oncoproteins and their molecular targets during the formation, maintenance, and recurrence of childhood brain tumors. We also briefly summarize recent progress in the development of therapeutic approaches for pharmacological inhibition of MYC activity in these tumors.

A combination of two new therapies already in clinical trials for the treatment of primary malignant brain tumors may also be effective in the treatment of breast cancer that has spread to the brain, according to US researchers.. The team demonstrated their new approach, which combines immunotherapy with gene therapy, in mice. They write about their findings in the most recent issue of the journal Clinical Cancer Research.. Breast cancer is the most common cancer in women. The National Cancer Institute of the US estimates that in the US in 2013 some 235,000 new cases of breast cancer will arise, and the disease will claim some 40,000 lives.. The vast majority of deaths from cancer are because of metastasis, where the cancer spreads from the primary site to other parts of the body, such as the brain.. Patients with metastatic brain tumors have a very poor prognosis since most current treatments rely on chemotherapy, and many of the drugs are ineffective because the brain is protected by the ...

Ivanhoe Newswire) - Glioblastoma is the most common brain malignancy and one of the most lethal of all cancers, killing most victims within 12-15 months of diagnosis. It is also one of the most chemotherapy-radiation resistant cancers. Researchers found that by blocking brain cancer cells from getting large amounts of cholesterol they could provide a new strategy to battle glioblastoma, according to this study.. The study, done in cells lines, mouse models and analysis of tissue from brain cancer patients, uncovered a novel mechanism by which the most commonly activated oncogene, the mutated epidermal growth factor receptor (EGFR), overcomes normal cell regulatory mechanisms to feed large amounts of cholesterol to the brain cancer cells, Dr. Paul Mischel, a professor of pathology and laboratory medicine and molecular and medical pharmacology, a Jonsson Cancer Center researcher and senior author of the study, was quoted as saying.. The study shows that EGFRvIII, common in glioblastoma, promotes ...
A brain tumor is a mass or growth of abnormal cells in your brain or close to your brain. Many different types of brain tumors exist. Some brain tumors are noncancerous (benign), and some Brain tumors are cancerous (malignant). Brain tumors can begin in your brain (primary brain tumors), or cancer can begin in other parts of your body and spread to your brain (secondary, or metastatic, brain tumors).. How quickly a brain tumor grows can vary greatly. The growth rate as well as location of a brain tumor determines how it will affect the function of your nervous system. Brain tumor treatment options depend on the type of brain tumor you have, as well as its size and location. ...
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 ...
On their own, PARP inhibitors kill certain types of cancer cells by stopping their ability to repair gene faults. They are being used in clinical trials to treat patients with specific types of breast, ovarian and prostate cancers. PARP inhibitors can also be combined with existing cancer treatments such as chemotherapy and radiotherapy and it is hoped that this combination will be effective against a wider range of cancer types including brain tumours.. This latest trial is being funded and managed by the charitys Drug Development Office (DDO).. Dr Nigel Blackburn, director of drug development at Cancer Research UKs Drug Development Office, said: "Its incredibly encouraging to launch this trial combining two drugs which have both been developed through work led by Cancer Research UK scientists. We hope that this new treatment approach will help extend the lives of brain cancer patients for whom the disease has returned.. "Were heavily investing in further ways to develop targeted treatments ...
Brain metastases are a common and devastating complication in patients with malignant melanoma. Therapeutic options for these patients are limited, and the prognosis is usually poor.. Object. A retrospective review of 6953 patients with melanoma treated at a single institution was undertaken to identify demographic factors associated with the development of clinically significant brain metastases in 702 of these patients and to determine the factors influencing the prognosis of this population to permit more informed recommendations regarding surgical therapy.. Methods. Factors found to be associated with the development of brain metastases included male gender, primary lesions located on mucosal surfaces or on the skin of the trunk or head and neck, thick or ulcerated primary lesions, and histological findings of acral lentiginous or nodular lesions. The overall median survival time of all patients with brain metastases was 113.2 days, and these metastases contributed to the death of 94.5% of ...

Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these). Among the malignant brain cancers, gliomas of the brainstem and pons, glioblastoma multiforme, and high-grade (highly anaplastic) astrocytoma are among the worst. In these cases, untreated survival usually amounts to only a few months, and survival with current radiation and chemotherapy treatments may extend that time from around a year to a year and a half, possibly two or more, depending on the patients condition, immune function, treatments used, and the specific type of malignant brain neoplasm. Surgery may in some cases be curative, but, as a general rule, malignant brain cancers tend to regenerate and emerge from remission easily, especially highly malignant cases. In such cases, the goal is to excise as much of the ...
Malignant primary brain tumors, gliomas, often overexpress both platelet-derived growth factor (PDGF) ligands and receptors providing an autocrine and/or paracrine boost to tumor growth. Glioblastoma multiforme (GBM) is the most frequent glioma. Its aggressive and infiltrative growth renders it extremely difficult to treat. Median survival after diagnosis is currently only 12-14 months. The present review describes the use of retroviral tagging to identify candidate cancer-causing genes that cooperate with PDGF in brain tumor formation. Newborn mice injected intracerebrally with a Moloney murine leukemia retrovirus carrying the sis/PDGF-B oncogene and a replication competent helper virus developed brain tumors with many characteristics of human gliomas. Analysis of proviral integrations in the brain tumors identified almost 70 common insertion sites (CISs). These CISs were named brain tumor loci and harbored known but also putative novel cancer-causing genes. Microarray analysis identified ...

PY - 2011/11. Y1 - 2011/11. N2 - Infections represent a serious and frequent complication in neuro-oncology patients. Decreased immune defences, along with poor nutritional status are the main predisposition factors. The combined therapeutic strategies of chemotherapy and radiotherapy may favour bone marrow depression and further increase the risk of developing opportunistic infections in brain tumour patients. The spectrum of infections in neuro-oncology patients is large and includes opportunistic infections by bacteria, viruses, fungi and parasites. Importantly, a high index of suspicion for opportunistic infections in general should be maintained, especially in glioma patients receiving dose-dense schedules of temozolomide. After neurosurgical procedures, infections most commonly present as ...
A new report published in the journal Neuro-Oncology and funded by the American Brain Tumor Association (ABTA) finds that malignant brain tumors are the most common cause of cancer-related deaths in adolescents and young adults aged 15-39 and the most common cancer occurring among 15-19 year olds.
Although the available models, whether at the cellular, tissue, or animal level, do not exactly represent the biology of human brain tumors, animal models can offer significant insights into these tumors, providing a better understanding of biological mechanisms underlying tumor generation, growth, angiogenesis, invasion, and metastasis. Animal Models of Brain Tumors brings together developments and discoveries in "in vivo" experimental tumor research that have provided advances in our understanding of the cellular and molecular mechanisms involved in the generation, progression, and clinical outcome of brain neoplasms. Broken into convenient sections, this thorough volume includes topics such as animal model insights into human brain neoplasms, the cellular, molecular, and genetic basis of brain tumors, therapies in the treatment of malignant glioma, as well as imaging technologies in animal tumor models, i.e. measuring brain tumor growth and metabolism. Written for the popular Neuromethods ...

Dr. Cuis research uses integrated systems biology approaches to discover new strategies for treating malignant tumors, especially primary (glioblastoma) and secondary (metastatic) brain tumors. He is applying multidisciplinary approaches, including assay development, high-throughput and high-content screening, as well as computational modeling to discover new compounds and explore new treatment combinations. He developed a screening platform for glioma growth and invasion using bioluminescence imaging and uses it to screen potential drugs that inhibit tumor cell migration for better management of malignant glioblastoma. He has investigated a new cocktail strategy for treating brain tumors by combining whole brain radiotherapy, a neuroprotection compound, and an angiogenesis inhibitor. He has also obtained pilot project funding from the NCI to conduct his studies. His new drug combination study on brain tumors is under study in a new clinical trial in collaboration with Dr. Pamela New at the HMH ...
Primary brain tumors originate in the brain. The tumor cells do not travel to the brain from other parts of the body and, in most cases, primary brain tumor cells do not travel to other parts of the body either. The most common exception to this rule is the primary brain tumor of childhood called medulloblastoma, which can spread to the lymph nodes, bone marrow, lungs or other parts of the body. But even in this case, it is unusual for medulloblastoma to spread outside the nervous system. Pathologists classify primary brain tumors into two groups: the gliomas, composed of "glial" cells that invade the neural tissue surrounding them; and the nonglial tumors, which are not composed of glial cells and compress, rather than invade, the neighboring brain tissue as they grow ...
Today, more than 612,000 people are living with primary brain tumors in the United States. An estimated 62,930 new cases of primary non-malignant and malignant brain and central nervous system tumors are expected to be diagnosed in the United States in 2010.. These numbers have increased since federally mandated cancer data-collection processes include data on benign brain tumors. Until passage of this legislation, it was generally accepted that the incidence of primary brain tumors was almost certainly underreported. Two percent of routine autopsies reveal undiagnosed primary brain tumors, and most states did not require physicians to report the incidence of noncancerous primary brain tumors to state or federal registries.. ...
This paper proposes a novel global-to-local nonrigid brain MR image registration to compensate for the brain shift and the unmatchable outliers caused by the tumor resection. The mutual information between the corresponding salient structures, which are enhanced by the joint saliency map (JSM), is maximized to achieve a global rigid registration of the two images. Being detected and clustered at the paired contiguous matching areas in the globally registered images, the paired pools of DoG keypoints in combination with the JSM provide a useful cluster-to-cluster correspondence to guide the local control-point correspondence detection and the outlier keypoint rejection. Lastly, a quasi-inverse consistent deformation is smoothly approximated to locally register brain images through the mapping the clustered control points by compact support radial basis functions. The 2D implementation of the method can model the brain shift in brain tumor resection MR images, though the theory holds for the 3D case.
Brain tumours are the second most common cancer in children after leukemia, with the incidence increasing at a rate of five to 10 per cent per year. More than 200 Canadian children are diagnosed with brain tumours each year, with approximately 100 new cases at The Hospital for Sick Children alone. Despite advances in treatment, survival from brain tumours remains lower than for other forms of cancer. Medulloblastoma, a malignant tumour that occurs in the cerebellum, accounts for 20 per cent of all paediatric brain tumours. It is a rapidly growing tumour that is more common in boys than girls ...
Tumors are never something to joke around about; they are dangerous, unpredictable, and they can even be fatal. They can appear nearly anywhere in the human body, at basically any point in time. In fact, one of the most dangerous habitats for a tumor is the brain. A complicated and mysterious part of the human body already, the brain controls almost everything, and a tumor appearing in this region can be devastating. They are difficult to remove, and they can have disastrous mental and physical consequences. Even worse, they can present themselves at any age. This makes children susceptible, and what could be worse than that? With around 1,500 children diagnosed a year, pediatric brain tumors are not the most common cause of death in children (1). However, they are the most common type of pediatric tumor, and they have the highest mortality rate over all other childhood cancers. Despite its reputation, this deadly disease has had no improvements regarding treatment methods in the past. Until ...

The majority (40-60%) of patients with metastatic her2 positive breast cancer develop brain metastases at some point in their disease course. One should maintain a low threshold for imaging the brain if a patient reports any neurologic symptoms, even if subtle. Oligometastases should be considered for surgical excision or radiotactic surgery followed by whole brain radiotherapy. Retreatment of progressive brain metastases with further radiation is sometimes feasible and beneficial, if the disease was controlled for an extended period (generally at least ten months) after initial radiotherapy. Several systemic drugs have some penetration into the blood brain barrier and may enhance control of brain metastases from breast cancer. These include capecitabine, lapatinib, anthracyclines, and cisplatin. While some other drugs have been used to treat primary brain tumors, their ability to control brain metastases of breast cancer origin has been disappointing ...
DC vaccination approaches for brain tumors have been implemented in human clinical trials (5-10). Several clinical trials for GBM using DC vaccines have shown cellular and humoral antitumor immune responses; and albeit safe, the clinical efficacy of DC vaccination for GBM remains limited (3, 5-10). Our group has shown that in situ Ad-Flt3L/TK-mediated immunogene therapy elicits an influx of DCs, macrophages, CD4+ T cells, and CD8+ T cells into the brain tumor microenvironment (17) and stimulates effective anti-GBM immune response resulting in tumor regression and long-lasting CD8+ T-cell-mediated antitumor immunologic memory in several mouse and rat orthotopic brain tumor models (16, 18, 22-24, 29). On the basis of these data, a phase I clinical trial for GBM was recently cleared by the FDA and is slated to commence in 2011.. The combined conditional cytotoxic/immunostimulatory gene therapy approach, utilizes HSV1-TK to kill actively dividing brain tumor cells in the presence of GCV, thereby ...

The brain tumor is typical and frequently found in middle age and elderly dogs nevertheless they are also able to impact the younger person also. If puppy includes a transplant then it might be the indications a thyroid gland is present.. The most typical kinds that frequently seen in dogs include astrocytomas, oligodendrogliomas, and meningiomas. The tumor is normally broad spread on several websites on the brain as opposed to one seen position.. A number of these tumors appear straight from the brain tissue whereas other forms spread to your mind by blood because the brain commands extensive blood source.. The seriousness depends mostly on the mind location in which the tumor appears and how quickly they develop. Canine seizures may also be brought on by other problems like low blood glucose heart or heart issues. ...

Inhibiting fatty acid synthesis in brain cancer cells may offer a new option to treat about 50 percent of deadly glioblastomas that are driven by amplified signaling of the epidermal growth factor receptor (EGFR), according to a first-of-its-kind study by researchers at UCLAs Jonsson Comprehensive Cancer Center.. Rapidly dividing cancer cells require fatty acids for the formation of new membranes. The fatty acids also provide an alternative energy source for the cancer cells, and may be important for regulating cell signaling, said Dr. Paul Mischel, a professor of pathology and laboratory medicine and senior author of the study, which appears in the Dec. 15 issue of the journal Science Signaling.. While healthy cells take up the fat they need to function through the blood stream, the cancer cells prefer to be autonomous of the body and convert glucose for the fatty acids they need to multiply out of control.. "This suggests an important link between cancer progression and fatty acid synthesis ...

Investigators will determine in human brain tumor cells and in an animal model whether a genetically modified "immunotherapy" more effectively targets brain tumor, decreases its recurrence, and minimizes treatment complications. Aggressive malignant brain tumors (gliomas) kill within two years. Conventional treatment involves surgical removal, followed by radiation and chemotherapeutic agents. This regimen has only slightly prolonged life, however, and produces serious side effects." Immunotherapies" represent a new and potentially more effective approach. They employ strategies to strengthen a patients own immune response. The Baylor investigators recently developed a promising immunotherapy and now want to improve upon it. They took immune T cells from patients blood and genetically modified the immune T cells to recognize, attach to, and kill a specific antigen (a peptide) called, HER2 on the tumor cells surface. They tested the therapy in mice implanted with the patients tumor cells. ...

Background Chemotherapeutic drugs and newly developed therapeutic monoclonal antibodies are adequately delivered to most solid and systemic tumors. However, drug delivery into primary brain tumors and metastases is impeded by the blood-brain tumor barrier (BTB), significantly limiting drug use in brain cancer treatment. Methodology/Principal Findings We examined the effect of phosphodiesterase 5 (PDE5) inhibitors in nude mice on drug delivery to intracranially implanted human lung and breast tumors as the most common primary tumors forming brain metastases, and studied underlying mechanisms of drug transport. In vitro assays demonstrated that PDE5 inhibitors enhanced the uptake of [14C]dextran and trastuzumab (Herceptin®, a humanized monoclonal antibody against HER2/neu) by cultured mouse brain endothelial cells (MBEC). The mechanism of drug delivery was examined using inhibitors for caveolae-mediated endocytosis, macropinocytosis and coated pit/clathrin endocytosis. Inhibitor analysis strongly

A novel Trojan horse method of treating brain cancer has increased the survival time of mice by one half. A cancer-killing virus was introduced into neural stem cells (NSCs) and these infected cells were introduced into mouse brain tumors. This increased the average lifespan of the mice from 63 to 93 days. The mice had been injected with a human form of brain cancer called glioblastoma, the most common and aggressive form of brain cancer. The average survival time for people with this condition is only 15 months. These brain tumors are also spread throughout the brain, making them difficult to target with conventional cancer treatments. Scientists can use viruses to target cancer cells, where they aggressively multiply and so kill the tumor. However, the bodys own immune system often quickly destroys the virus before it can reach the tumor. To avoid this, researchers placed the virus inside NSCs which instinctively migrate towards cancer cells. The NSCs act as a Trojan horse to hide the ...

These approaches provide the basis for risk-adapted personalized treatment options.. ...
This phase I trial studies the side effects and best dose of trametinib with or without whole brain radiation therapy in treating patients with brain metastases. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x rays to kill tumor cells. Drugs, such as trametinib, may make tumor cells more sensitive to radiation therapy. Giving trametinib with whole brain radiation therapy may be an effective treatment for brain metastases.

It is often assumed that a parenchymal brain lesion which shows no contrast enhancement on magnetic resonance imaging(MRI) is a"low-grade tumor". We investigated a series of 20 patients with nonenhancing cerebral gliomas ; all underwent stereotactic biopsy or open resection, and histological diagnoses were astrocytoma(n=7), anaplastic astrocytoma(n=7), oligodendroglioma(n=5), and ganglioglioma(n=1). Before surgery, 11 patients underwent [18F] fluorodeoxyglucose positron emission tomography(FDG-PET), and this showed hypermetabolic features in two of four patients with anaplastic astrocytomas and in one of seven with astrocytomas or oligodendrogliomas. Among 17 patients, the mean Ki-67 labeling index was 4.4+/-4.3(range : 0.1-16.7), and the standard error was 1.04. These results indicate that in cerebral gliomas, the enhancing pattern seen on MRI cannot predict the degree of malignancy, and we suggest that even if imaging is consistent with "low-grade glioma", histological verification and close ...

The prevalence of headache in patients with intracranial tumours ranges from 32 to 71%. Likelihood of headache is greater in young patients (including children), in patients with a history of primary headache, and with rapid growth of the tumour or posterior fossa or midline localization. A low threshold for investigation is suggested in any patient with a current or prior history of cancer. There are no pathognomonic features of 7.4.1 Headache attributed to intracranial neoplasm, although progression or deterioration is a key feature. The other suggestive symptoms (severe, worse in the morning and associated with nausea and vomiting) are not a classical triad; they are more likely in the context of intracranial hypertension and with posterior fossa tumours..
