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.
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 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)

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.

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 containing cyst-like formations or producing mucin or serum.
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)

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)
Histochemical localization of immunoreactive substances using labeled antibodies as reagents.
Tumors or cancers of the KIDNEY.
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.

A malignant cystic or semisolid tumor most often occurring in the ovary. Rarely, one is solid. This tumor may develop from a mucinous cystadenoma, or it may be malignant at the onset. The cysts are lined with tall columnar epithelial cells; in others, the epithelium consists of many layers of cells that have lost normal structure entirely. In the more undifferentiated tumors, one may see sheets and nests of tumor cells that have very little resemblance to the parent structure. (Hughes, Obstetric-Gynecologic Terminology, 1972, p184)

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)

N2 - Longitudinal MRI was applied to monitor intracranial initiation and development of brain metastases and assess tumor vascular volume and permeability in a mouse model of breast cancer brain metastases. Using a 9.4T system, high resolution anatomic MRI and dynamic susceptibility contrast (DSC) perfusion MRI were acquired at different time points after an intracardiac injection of brain-tropic breast cancer MDA-MB231BR-EGFP cells. Three weeks post injection, multifocal brain metastases were first observed with hyperintensity on T2-weighted images, but isointensity on T1-weighted post contrast images, indicating that blood-tumor-barrier (BTB) at early stage of brain metastases was impermeable. Follow-up MRI revealed intracranial tumor growth and increased ...
Breast cancer brain metastases (BCBM) develop in about 20-30% of breast cancer (BC) patients. BCBM are associated with dismal prognosis not at least due to lack of valuable molecular therapeutic targets. The aim of the study was to identify new molecular biomarkers and targets in BCBM by using complementary state-of-the-art techniques. We compared array expression profiles of three BCBM with 16 non-brain metastatic BC and 16 primary brain tumors (prBT) using a false discovery rate (FDR) p | 0.05 and fold change (FC) | 2. Biofunctional analysis was conducted on the differentially expressed probe sets. High-density arrays were employed to detect copy number variations (CNVs) and whole exome sequencing (WES) with paired-end reads of 150 bp was utilized to detect gene mutations in the three BCBM. The top 370 probe sets that were differentially expressed between BCBM and both BC and prBT were in the majority comparably overexpressed in BCBM and included, e.g. the coding genes BCL3, BNIP3, BNIP3P1, BRIP1,

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 ...

Y1 - 2015/2/26. N2 - In 2010 it was estimated that .688 000 Americans were living with a primary brain tumor (PBT) corresponding to a U.S. prevalence rate of approximately 221.8 per 100 000 people. Five-year survival is 96.1% in nonmalignant PBTs, 34% in malignant PBTs for all ages, and 71% in children [1985-2005]. Case fatality rates have decreased in the U.S. since the 1970s for nonmalignant PBTs and for medulloblastoma, oligodendroglioma, and astrocytoma. Statistics of increasing survival highlight the importance of rehabilitation interventions to improve function and quality of life in survivors. PBT motor dysfunction is multifactorial, occurring as a result of direct effects of tumor and/or swelling or as a result of treatments; etiologies include encephalopathy, myopathy, neuropathy, ...
Little is known about tumor-associated vasogenic edema in brain metastasis, yet it causes significant morbidity and mortality. Our purpose was to characterize edema in patients treated with anti-PD-1 and to study potential causes of vessel leakage in humans and in pre-clinical models. We analyzed tumor and edema volume in 18 non-small cell lung (NSCLC) and 18 melanoma patients with untreated brain metastases treated with pembrolizumab on a phase II clinical trial. Melanoma brain metastases were stained with anti-CD34 to assess vessel density and its association with edema. We employed an in vitro model of the blood-brain barrier using short-term cultures from melanoma brain and extracranial metastases to determine tight junction resistance as a measure of vessel leakiness. Edema volumes are similar in NSCLC and melanoma brain metastases. While larger tumors tended to have more edema, the correlation was weak (R2 = 0.30). Patients responding to pembrolizumab had concurrent shrinkage of edema volume and

Between September 2012 and December 2017, 112 consecutive patients ≥18 years old receiving combined SRS and ipilimumab or nivolumab for one to ten melanoma brain metastases were retrospectively evaluated. In general, patients with lesions up to 2.5 cm in size were treated with single-fraction SRS, while larger lesions located near or in eloquent areas (i.e., motor, somatosensory, speech, visual cortices, basal ganglia, thalamus, and the brainstem) received multi-fraction SRS to minimize potential increased risk of late radiation-induced brain necrosis (RN).. All radiographic, surgical, and pathological information were drawn from a prospectively maintained database of patients with brain tumors treated at Sant Andrea Hospital and UPMC Hillman Cancer Center San Pietro Hospital. Thirty-two patients were excluded due to insufficient clinical information, previous use of anti-PD-1/PD-L1, brain surgery or radiation. Previous adjuvant therapies, including ipilimumab or BRAF/MEK inhibitors, were ...
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 ...

The antitumor activity was effective on small tumors and, to a lesser extent, on large tumors or tumors existing in vivo for a longer duration, Immunohistochemical analysis revealed cellular infiltrates (granulocytes, macrophages, and CD4+ and CD8+ T cells) at both the vaccine site and the tumor site, indicating that immune responses were similarly activated when tumor vaccine was inoculated in the brain, as at the subcutis. Additional studies demonstrated that the therapeutic ...
Our research is currently focused on the pharmacological aspects of a multidisciplinary project within the frontier of cancer immunotherapy where nanotechnology, immunology, chemical biology, biotechnology and animal modeling will provide the rationale for novel anticancer treatments. This approach is based on the design of precision nanomedicines that will interfere within tumor-host interactions and stimulate the immune system to attack the tumor cells. We are synthesizing PLGA-based nanovaccines targeting the dendritic cells to activate T cells against primary and secondary brain neoplasms such as glioblastoma, melanoma brain metastases and breast cancer brain metastases. Another immunotherapy approach tagging heteroaryl chemotherapeutic drug molecules with a ketone functional group and employing it for Antibody-Drug Conjugates (ADC) applications was recently published. This project is the basis for an ERC Advanced grant awarded to our lab in 2019-2024. Based on this project, we signed a ...
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.

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 ...

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 ...

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.

Whole-brain radiation therapy (WBRT) delivers radiation treatments to the entire brain over a period of many weeks. WBRT is typically used if there are more than a few areas of cancer in the brain. WBRT helps to shrink the tumors and improve symptoms. WBRT also may be used in place of, or in addition to, stereotactic radiosurgery. The side effects of WBRT include thought and memory problems, so its important to have a conversation with your doctor to weigh the risks and benefits of WBRT in your situation. If you have HER2-positive breast cancer that has moved into the brain, you may be able to delay whole-brain radiation therapy by using the combination of Tykerb (chemical name: lapatinib) and Xeloda (chemical name: capecitabine). For more information, see Targeted Therapies to Treat Recurrent and Metastatic Breast Cancer. ...

Although targeted therapies have produced dramatic advances in our ability to control some types of advanced lung cancer, growth of the disease in the brain remains a major problem. Radiation is often used to treat deposits in the brain, but the best technique to deliver radiation can be controversial. Whole-brain radiation therapy, as its name suggest, treats the entire brain but can be associated with notable cognitive side effects. Another strategy, radiosurgery, directs highly-focused radiation only to the sites of metastasis, largely sparing the normal brain. The challenge has been to define in which circumstances each technique is best. The debate has centered on the number of brain metastases, with the field generally agreeing that with three or fewer deposits, radiosurgery is the preferred approach, and then switching to the use of whole-brain radiation to treat four or more deposits.. A University of Colorado Cancer Center study published today in the Journal of Thoracic Oncology ...

Her radiation-induced brain necrosis could have been focal or diffuse, depending on the modality of treatment. The five fractions of focal radiation to the local tumor bed could have resulted in either focal necrosis around the tumor bed or metastatic recurrance. In her case she developed metastatic recurrance as per Pet Scan of August 2000 showing abnormal foci of radiotracer accumulation within the right cerebellar hemisphere, right cerebellopontine angle, pons and base of the fourth ventricle consistent with new metastatic foci. Her previous tumor resection of July 1998, was a 3.5cm necrotic mass in the right cerebellar hemisphere. Recurrance of a cerebral metastasis was very likely to happen in the future. It did, observed via an enhanced MRI ...
Clin Cancer Res. 2004 Oct 1;10(19):6411-7. A phase I study of topical Tempol for the prevention of alopecia induced by whole brain radiotherapy. Metz JM¹, Smith D, Mick R, Lustig R, Mitchell J, Cherakuri M, Glatstein E, Hahn SM. ¹Department of Radiation Oncology, University of Pennsylvania, Philadelphia Abstract PURPOSE: Complete alopecia is a universal complication of whole brain radiation therapy which contributes to patient anxiety over treatment. Tempol, a nitroxide radioprotector, has been shown to protect against radiation-induced alopecia in an animal model. This phase Ib study was designed to evaluate the safety and side effect profile of topical Tempol in patients with brain metastases being treated with whole brain radiotherapy. EXPERIMENTAL DESIGN: Twelve patients with metastatic cancer to the brain were enrolled in the study between October 2000 and February 2003. Tempol (70 mg/ml concentration solution) was applied topically to the scalp 15 minutes before and washed off immediately
The goal of this clinical research study is to learn whether Tarceva (erlotinib hydrochloride), when given in addition to whole brain radiation therapy,

Title:Anti-cancer Therapies in High Grade Gliomas. VOLUME: 10 ISSUE: 3. Author(s):Cristiana Pistol Tanase, Ana-Maria Enciu, Simona Mihai, Ana Iulia Neagu, Bogdan Calenic and Maria Linda Cruceru. Affiliation:Victor Babes National Institute of Pathology, Dept. of Biochemistry-Proteomics, no 99-101 Splaiul Independentei, 050096 sect 5 Bucharest, Romania.. Keywords:Antiangiogenic therapy, cancer stem cells, glioma, microRNA, personalized medicine, PI-3K.. Abstract:High grade gliomas represent one of the most aggressive and treatment-resistant types of human cancer, with only 1-2 years median survival rate for patients with grade IV glioma. The treatment of glioblastoma is a considerable therapeutic challenge; combination therapy targeting multiple pathways is becoming a fast growing area of research. This review offers an up-to-date perspective of the literature about current molecular therapy targets in high grade glioma, that include angiogenic signals, tyrosine kinase receptors, nodal signaling ...
Whole brain radiotherapy (WBRT) is a palliative option for patients with brain metastases that alleviates symptoms, decreases the use of corticosteroids needed to control tumor-associated edema, and potentially improves overall survival. It has been reported to increase the risk of cognitive decline. McTyre, E; Scott, J; Chinnaiyan, P (2013). Whole brain radiotherapy for brain metastasis. Surg Neurol Int. 4: S236-44. doi:10.4103/2152-7806.111301. PMC 3656558 . PMID 23717795. Whole-Brain Radiotherapy: Risks Worth Benefit?. Medscape.com. Retrieved August 20, 2015 ...
To retrospectively access outcome and toxicity of whole brain radiotherapy (WBRT) in patients with multiple brain metastases (BM) from malignant melanoma (MM). Results of 87 patients (median age 58 years; 35 female, 52 male) treated by WBRT for BM of MM between 2000 and 2011 were reviewed. Total dose applied was either 30 Gy in 10 fractions (n = 56) or 40 Gy in 20 fractions (n = 31). All but 9 patients suffered from extra-cerebral metastases. Prior surgical resection of BM was performed in 18 patients, salvage stereotactic radiosurgery in 13 patients. Mean follow-up was 8 months (range, 0-57 months), the 6- and 12-months overall-(OS) survival rates were 29.2% and 16.5%, respectively. The median OS was 3.5 months. In cerebral follow-up imaging 6 (11) patients showed a complete (partial) remission, while 11 (17) patients had stable disease (intra-cerebral tumor progression). In comparison of total dose, the group treated with 40 Gy in 20 fractions achieved a significant longer OS (p = 0.003, median 3.1 vs
The effect of radiosurgery on spontaneous haemorrhage into metastatic brain tumours has not been sufficiently investigated. This study showed that haemorrhage was observed in 7.4% of patients (3.8% of tumours) before radiosurgery and in 18.5% of patients (7.6% of tumours) after radiosurgery. This would not necessarily imply that radiosurgery increases the likelihood of haemorrhage, as the incidence of intratumour haemorrhage is quite different between the early and later stages of brain metastases, which grow very rapidly. Rather, the incidence of haemorrhage after radiosurgery (18.5%) was no greater than that of untreated tumours reported previously (0-50%).3 However, it is not possible to state definitively whether radiosurgery increases, does not change, or decreases the risk of haemorrhage, because of the lack of a control group. However, 50% of the observed haemorrhages occurred within one month of the procedure. As most haemorrhagic tumours were under good local control at the time of the ...

Anaplastic astrocytoma is a rare WHO grade III type of astrocytoma, which is a type of cancer of the brain. In the United States, the annual incidence rate for Anaplastic astrocytoma is 0.44 per 100,000 persons Anaplastic astrocytomas fall under the category of high grade gliomas (WHO grade III-IV), which are pathologically undifferentiated gliomas that carry a poor clinical prognosis. Unlike glioblastomas (WHO grade IV), anaplastic astrocytomas lack vascular proliferation and necrosis on pathologic evaluation. Compared to grade II tumors, anaplastic astrocytomas are more cellular, demonstrate more atypia, and mitoses are seen. Initial presenting symptoms most commonly are headache, depressed mental status, focal neurological deficits, and/or seizures. The growth rate and mean interval between onset of symptoms and diagnosis is approximately 1.5-2 years but is highly variable, being intermediate between that of low-grade astrocytomas and glioblastomas. Seizures are less common among patients ...
The researchers found that there was less cognitive deterioration at 3 months after stereotactic radiosurgery alone (40/63 patients, 64%) than when combined with whole brain radiotherapy (44/48 patients, 92%). Quality of life was higher at three months with stereotactic radiosurgery alone, including overall quality of life. There was no significant difference in functional independence at three months between the treatment groups. Median overall survival was 10.4 months for stereotactic radiosurgery alone and 7.4 months for stereotactic radiosurgery plus whole brain radiotherapy. For long-term survivors, the incidence of cognitive deterioration was less after stereotactic radiosurgery alone at three months and at 12 months.. In the absence of a difference in overall survival, these findings suggest that for patients with one to three brain metastases amenable to radiosurgery, stereotactic radiosurgery alone may be a preferred strategy, the authors write.. The debate between whole brain ...

Background: The atmosphere of valley of Kashmir is ideal for fresh and dry fruit production. Millions of tons of pesticides, insecticides and fungicides (chemicals like chlorpyriphos, mancozeb, captan, dimethoate, phosalone, etc.) are being used by the orchard farmers to spray the plants, fruits and the leaves every year. The increasing trend in the incidence of primary malignant brain tumors in orchard farmers of Kashmir is alarming. Aim: To determine the relationship between the patients of primary malignant brain tumors and their occupation. Materials and Methods: Retrospectively case files along with death certificates of 432 patients of primary malignant brain tumors and 457 controls (non-tumor neurologic diseases), admitted for treatment simultaneously over a period of 4 years from January 2005 to December 2008, to the Department of Neurosurgery, Sher-I-Kashmir Institute of Medical Sciences (SKIMS), Kashmir, were studied.

The June 2012 International Society of Pediatric Neuro Oncology (ISPNO) meeting in Toronto, Canada featuried a Low Grade Glioma (LGG) Symposium. This was the third time the PLGA Foundation had sponsored a targeted session at ISPNO and interest in the low grade glioma field continues to grow amongst scientists and medical experts because of meeting such as these.. The ISPNO meets once every 2 years and attracts an international audience of over 1000 experts in the clinical and research fields. The exposure that this symposium gives to this disease is immense. The LGG session sold out in the first two weeks with over 200 participants registering. This means that more attention will be focused on the most common forms of childrens brain tumors giving hope to the children battling these tumors for more effective treatments and a cure.. The LGG Session was moderated by Dr. Charles Eberhart, Associate Professor of Oncology, Pathology and Opthomology at Johns Hopkins University School of Medicine, and ...
Pediatric brain tumors are the second most common form of cancer and the leading cause of cancer-related morbidity and mortality in pediatrics. Until recently, the majority of research in pediatric brain tumors was focused on the highly aggressive embryonal tumors, such as medulloblastoma, and there have been recent dramatic advances in the understanding of this subset of tumors.. However, more than half of childhood primary central nervous system tumors are gliomas and, unlike the situation in adulthood, low-grade gliomas constitute most pediatric gliomas. Pediatric low-grade gliomas arise throughout the nervous system and, despite their often indolent nature - dependent on their location in the nervous system - they may not be amenable to safe, extensive resections and can result in significant morbidity and, at times, mortality.. Radiation has been a conventional second step in therapy when surgery is not deemed feasible. In many children, this can result in excellent long-term control, but ...
A case of anaplastic pleomorphic xanthoastrocytoma (PXA) in a 9-year-old girl is reported. Histological features of PXAs are cellular pleomorphism of GFAP-positive cells, with intracytoplasmic lipidic vacuoles and a reticulin network, bizarre giant cells, low mitotic activity, and lack of necrosis and of endothelial vascular proliferations. These tumors are generally reported to have a favorable postoperative course. In our case, a poor clinical prognosis and spread of the illness through the CSF was observed. Immunohistochemical features of the tumor, which were histologically anaplastic in nature, were analyzed. There were small foci of necrosis in the sections of the material obtained at the first operation and extensive necrosis in that from the second operation, although the patient had not received radiotherapy between the operations. The presence of necrosis in PXA is an uncommon and significant feature. It predicts the poor prognosis seen in this case, and therefore this report strongly supports
In patients who had undergone surgery for brain metastases, the rate of recurrence at the resected site was similar between patients who received adjuvant whole-brain radiotherapy vs those who underwent adjuvant localized radiotherapy, according to a retrospective study by Hsieh et al in the journal Neurosurgery. However, localized radiotherapy was associated with a higher incidence of distant metastases.. Surgery followed by adjuvant whole-brain radiotherapy is a well-established treatment for brain metastases, particularly in patients who have a limited number of brain metastases. Yet discussions continue as to whether these patients require whole-brain radiotherapy or can be treated with localized radiotherapy. Localized radiotherapy is associated with fewer side effects compared with whole-brain radiotherapy, but some studies have documented an association with an increased risk for development of new intracranial metastases.. Thus, the investigators conducted a study to examine the rate of ...
Papillary thyroid carcinoma (PTC) is the most common type of thyroid carcinoma and has a relatively favorable prognosis. PTC brain metastases are rare, occurring in 0.1‑5% of cases in previous studies. In the present study, we treated 5 cases of PTC brain metastasis in our institute and retrospectively evaluated these patients. A retrospective database was generated from the patient medical records of our institution for the years between 1976 and 2011. The mean patient age at diagnosis was 64.6 years and the average duration from PTC resection to the detection of a brain metastasis using magnetic resonance imaging (MRI) or computed tomography (CT) was 91.7 months. The patients were treated with various combinations of surgery and radiation therapy. All 5 patients died and the mean overall survival following the diagnosis of a brain metastasis was 9.0 months. One patient succumbed to an intratumoral hemorrhage of the metastatic brain tumor. The remaining patients died following metastasis to ...
Glioblastomas (malignant glioma) are the most common adult malignant brain tumors, and 20% of all primary brain neoplasms are glioblastoma multiforme tumors. Glioblastoma multiforme (GBM; malignant glioma) is the highest-grade form of astrocytoma and makes up about two thirds of all brain astrocytomas.
Purpose of Study This exploratory clinical study will investigate FMISO (fluoromisonidazole) in patients with (1) newly diagnosed primary malignant brain tumors (WHO [World Health Organization] Grade III or IV glial-based tumors) who have not had a complete surgical resection and by contrast MRI (Magnetic resonance imaging) have residual tumor > 1.0 cm in diameter and will be receiving radiotherapy or (2) newly diagnosed brain metastasis (> 1.0 cm in diameter who will be receiving radiotherapy. The ability to accurately assess tumor hypoxia and accurately determine the amount/degree of tumor hypoxia could potentially change patient management once validated as tumor hypoxia is known to be associated with a poor prognosis [Eyler 2008].
The purpose of this study is to compare any good and bad effects of avoiding the hippocampus during whole-brain radiation to the usual whole-brain radiation. The hippocampus is part of the brain that is important for memory. Avoiding the hippocampus during whole-brain radiation could decrease the chance of side effects on memory and thinking. It also is possible that avoiding the hippocampus could have no benefit or could cause other side effects. Hippocampal avoidance also could lessen the effectiveness of whole-brain radiation. This study will allow the researchers to know whether this different approach is better, the same, or worse than the usual approach. To be better, the addition of the hippocampal avoidance technique to whole-brain radiation therapy should decrease the chance of side effects on memory or thinking by at least 14.5 ...

The present study included cases of malignant brain tumours diagnosed during 2007-2009 from across Sweden. For the cases diagnosed during 1997-2003 in our previous study (5), the prevalence of use of mobile phones was highest in the age group 30-54 years for men, and 35-54 years for women. Thus, we included the age group 18-75 years in this study to allow for the longest possible latency time (28). This is in contrast to the Interphone study, which included cases aged 30-59 years. Glioma is the most common malignant brain tumour, and the most common glioma subtype is astrocytoma. Glioblastoma multiforme (WHO grade IV) accounts for 60-75% of all astrocytoma, in this study 66% of the cases with astrocytoma. The peak incidence is between 45-75 years, with a mean age of 61 years and with 80% older than 50 years (29). Thus, limiting the upper age to 59 years for cases as in Interphone (3) would diminish the possibility of finding an increased risk for the long-term use of mobile phones.. Recall and ...
