Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
Medical History Taking
Giant Cell Arteritis
A systemic autoimmune disorder that typically affects medium and large ARTERIES, usually leading to occlusive granulomatous vasculitis with transmural infiltrate containing multinucleated GIANT CELLS. The TEMPORAL ARTERY is commonly involved. This disorder appears primarily in people over the age of 50. Symptoms include FEVER; FATIGUE; HEADACHE; visual impairment; pain in the jaw and tongue; and aggravation of pain by cold temperatures. (From Adams et al., Principles of Neurology, 6th ed)
Localized or diffuse reduction in blood flow through the vertebrobasilar arterial system, which supplies the BRAIN STEM; CEREBELLUM; OCCIPITAL LOBE; medial TEMPORAL LOBE; and THALAMUS. Characteristic clinical features include SYNCOPE; lightheadedness; visual disturbances; and VERTIGO. BRAIN STEM INFARCTIONS or other BRAIN INFARCTION may be associated.
A syndrome in the elderly characterized by proximal joint and muscle pain, high erythrocyte sedimentation rate, and a self-limiting course. Pain is usually accompanied by evidence of an inflammatory reaction. Women are affected twice as commonly as men and Caucasians more frequently than other groups. The condition is frequently associated with GIANT CELL ARTERITIS and some theories pose the possibility that the two diseases arise from a single etiology or even that they are the same entity.
A malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see NEUROECTODERMAL TUMOR, PRIMITIVE). The tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. Histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. Medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2060-1)
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.
Neuroectodermal Tumors, Primitive
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)
Polymers of ETHYLENE OXIDE and water, and their ethers. They vary in consistency from liquid to solid depending on the molecular weight indicated by a number following the name. They are used as SURFACTANTS, dispersing agents, solvents, ointment and suppository bases, vehicles, and tablet excipients. Some specific groups are NONOXYNOLS, OCTOXYNOLS, and POLOXAMERS.
Hepatitis C, Chronic
One of the type I interferons produced by peripheral blood leukocytes or lymphoblastoid cells. In addition to antiviral activity, it activates NATURAL KILLER CELLS and B-LYMPHOCYTES, and down-regulates VASCULAR ENDOTHELIAL GROWTH FACTOR expression through PI-3 KINASE and MAPK KINASES signaling pathways.
INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
A cell-cycle phase nonspecific alkylating antineoplastic agent. It is used in the treatment of brain tumors and various other malignant neoplasms. (From Martindale, The Extra Pharmacopoeia, 30th ed, p462) This substance may reasonably be anticipated to be a carcinogen according to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985). (From Merck Index, 11th ed)
Nuclear Medicine Department, Hospital
The application of scientific knowledge or technology to the field of radiology. The applications center mostly around x-ray or radioisotopes for diagnostic and therapeutic purposes but the technological applications of any radiation or radiologic procedure is within the scope of radiologic technology.
Image Processing, Computer-Assisted
The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.
Library Technical Services
A group of pathological conditions characterized by sudden, non-convulsive loss of neurological function due to BRAIN ISCHEMIA or INTRACRANIAL HEMORRHAGES. Stroke is classified by the type of tissue NECROSIS, such as the anatomic location, vasculature involved, etiology, age of the affected individual, and hemorrhagic vs. non-hemorrhagic nature. (From Adams et al., Principles of Neurology, 6th ed, pp777-810)
Translational Medical Research
A benign neoplasm that usually arises from the sympathetic trunk in the mediastinum. Histologic features include spindle cell proliferation (resembling a neurofibroma) and the presence of large ganglion cells. The tumor may present clinically with HORNER SYNDROME or diarrhea due to ectopic production of vasoactive intestinal peptide. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p966)
Hamartoma Syndrome, Multiple
A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.
Word Association Tests
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.
Metastasis stage, adjuvant treatment, and residual tumor are prognostic factors for medulloblastoma in children: conclusions from the Children's Cancer Group 921 randomized phase III study. (1/828)PURPOSE: From 1986 to 1992, "eight-drugs-in-one-day" (8-in-1) chemotherapy both before and after radiation therapy (XRT) (54 Gy tumor/36 Gy neuraxis) was compared with vincristine, lomustine (CCNU), and prednisone (VCP) after XRT in children with untreated, high-stage medulloblastoma (MB). PATIENTS AND METHODS: Two hundred three eligible patients with an institutional diagnosis of MB were stratified by local invasion and metastatic stage (Chang T/M) and randomized to therapy. Median time at risk from study entry was 7.0 years. RESULTS: Survival and progression-free survival (PFS) +/- SE at 7 years were 55%+/-5% and 54%+/-5%, respectively. VCP was superior to 8-in-1 chemotherapy, with 5-year PFS rates of 63%+/-5% versus 45%+/-5%, respectively (P = .006). Upon central neuropathology review, 188 patients were confirmed as having MB and were the subjects for analyses of prognostic factors. Children aged 1.5 to younger than 3 years had inferior 5-year estimates of PFS, compared with children 3 years old or older (P = .0014; 32%+/-10% v 58%+/-4%, respectively). For MB patients 3 years of age or older, the prognostic effect of tumor spread (MO v M1 v M2+) on PFS was powerful (P = .0006); 5-year PFS rates were 70%+/-5%, 57%+/-10%, and 40%+/-8%, respectively. PFS distributions at 5 years for patients with M0 tumors with less than 1.5 cm2 of residual tumor, versus > or = 1.5 cm2 of residual tumor by scan, were significantly different (P = .023; 78%+/-6% v 54%+/-11%, respectively). CONCLUSION: VCP plus XRT is a superior adjuvant combination compared with 8-in-1 chemotherapy plus XRT. For patients with M0 tumors, residual tumor bulk (not extent of resection) is a predictor for PFS. Patients with M0 tumors, > or = 3 years with < or = 1.5 cm2 residual tumor, had a 78%+/-6% 5-year PFS rate. Children younger than 3 years old who received a reduced XRT dosage had the lowest survival rate. (+info)
Hemangioblastoma mimicking tentorial meningioma: preoperative embolization of the meningeal arterial blood supply--case report. (2/828)A 72-year-old male presented with a primary hemangioblastoma of the posterior fossa with unusual dural attachment and meningeal arterial blood supply from the external carotid artery and marginal tentorial artery. Preoperative embolization facilitated complete resection of the tumor with no resultant neurological deficit. Hemangioblastoma must be included in the differential diagnosis of tumors with dural involvement. Preoperative embolization is very useful in such tumors. (+info)
Activation of the CD95 (APO-1/Fas) pathway in drug- and gamma-irradiation-induced apoptosis of brain tumor cells. (3/828)Chemotherapeutic agents and gamma-irradiation used in the treatment of brain tumors, the most common solid tumors of childhood, have been shown to act primarily by inducing apoptosis. Here, we report that activation of the CD95 pathway was involved in drug- and gamma-irradiation-induced apoptosis of medulloblastoma and glioblastoma cells. Upon treatment CD95 ligand (CD95-L) was induced that stimulated the CD95 pathway by crosslinking CD95 via an autocrine/paracrine loop. Blocking CD95-L/receptor interaction using F(ab')2 anti-CD95 antibody fragments strongly reduced apoptosis. Apoptosis depended on activation of caspases (interleukin 1beta-converting enzyme/Ced-3 like proteases) as it was almost completely abrograted by the broad range caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-fluoromethyl ketone. Apoptosis was mediated by cleavage of the receptor proximal caspase FLICE/MACH (caspase-8) and the downstream caspase CPP32 (caspase-3, Apopain) resulting in cleavage of the prototype caspase substrate PARP. Moreover, CD95 was upregulated in wild-type p53 cells thereby increasing responsiveness towards CD95 triggering. Since activation of the CD95 system upon treatment was also found in primary medulloblastoma cells ex vivo, these findings may have implications to define chemosensitivity and to develop novel therapeutic strategies in the management of malignant brain tumors.

Cicatricial fibromatosis mimics metastatic medulloblastoma. (4/828)Cicatricial fibromatoses usually occur in the anterior abdominal wall or in the extremities, but rarely in the scalp or the soft tissues of the neck. We report a case of desmoid fibromatosis that developed in a 15-year-old boy 8 months after surgery for cerebellar medulloblastoma. (+info)
Unexpected stomach uptake of technetium-99m-MDP. (5/828)Two pediatric cases are described in which the results of each patient's bone scan demonstrated abnormal stomach uptake. There have been a number of reports in the literature describing stomach uptake of bone agents, however, it is an uncommon finding. (+info)
Clinical features and outcomes in patients with non-acoustic cerebellopontine angle tumours. (6/828)OBJECTIVES: Non-acoustic tumours of the cerebellopontine angle differ from vestibular schwannomas in their prevalence, clinical features, operative management, and surgical outcome. These features were studied in patients presenting to the regional neuro-otological unit. METHODS: A retrospective analysis of clinical notes identified 42 patients with non-acoustic tumours of the cerebellopontine angle. Data were extracted regarding presenting clinical features, histopathological data after surgical resection, surgical morbidity and mortality, and clinical outcome (mean 32 months follow up). RESULTS: The study group comprised 25 meningiomas (60%), 12 epidermoid cysts/cholesteatomata (28%), and five other tumours. In patients with meningiomas, symptoms differed considerably from patients presenting with vestibular schwannomas. Cerebellar signs were present in 52% and hearing loss in only 68%. Twenty per cent of patients had hydrocephalus at the time of diagnosis. After surgical resection, normal facial nerve function was preserved in 75% of cases. In the epidermoid group, fifth, seventh, and eighth nerve deficits were present in 42%, 33%, and 66% respectively. There were no new postoperative facial palsies. There were two recurrences (17%) requiring reoperation. Overall, there were two perioperative deaths from pneumonia and meningitis. CONCLUSIONS: Patients with non-acoustic lesions of the cerebellopontine angle often present with different symptoms and signs from those found in patients with schwannomas. Hearing loss is less prevalent and cerebellar signs and facial paresis are more common as presenting features. Hydrocephalus is often present in patients presenting with cerebellopontine angle meningiomas. Non-acoustic tumours can usually be resected with facial nerve preservation. (+info)
Medullomyoblastoma: A case report. (7/828)Medullomyoblastoma is a rare tumour seen in childhood. We report a medullomyoblastoma occurring in the cerebellar vermis of a 4 year old boy. The light microscopic features, immunohistochemistry and histogenesis are described. (+info)
Choroid plexus papilloma of cerebellopontine angle with extension to foramen magnum. (8/828)A case of choroid plexus papilloma resembling meningioma of cerebellopontine (CP) angle with its extension to foramen magnum is presented. Occurrence of this tumour in CP angle is very rare. Its extension towards foramen magnum is further rare. It was a real diagnostic enigma preoperatively as the tumour was resembling meningioma upto some extent on radiological study. Retromastoid craniectomy with microsurgical excision of tumour and its extension was achieved in toto. Tumour was attached to few rootlets of lower cranial nerves which were preserved. Attachment of the tumour with lower cranial nerves again caused diagnostic confusion with neurofibroma intraoperatively. (+info)

Neurotrophin 3/TrkC-regulated proteins in the human medulloblastoma cell line DAOY - Zurich Open Repository and Archive
Medulloblastoma (MB) is the most common malignant childhood brain tumor and high neurotrophin (NP) receptor TrkC mRNA expression was identified as a powerful independent predictor of favorable survival outcome. In order to determine downstream effector proteins of TrkC signaling, the MB cell line DAOY was stably transfected with a vector containing the full-length TrkC cDNA sequence or an empty vector control. A proteomic approach was used to search for expressional changes by two mass spectrometric methods and immunoblotting for validation of significant results. Multiple time points for up to 48 h following NP-3-induced TrkC receptor activation were chosen. Thirteen proteins from several pathways (nucleoside diphosphate kinase A, stathmin, valosin-containing protein, annexin A1, dihydropyrimidinase-related protein-3, DJ-1 protein, glutathione S-transferase P, lamin A/C, fascin, cofilin, vimentin, vinculin, and moesin) were differentially expressed and most have been shown to play a role in ...

Brain Sciences | Free Full-Text | 4SC-202 as a Potential Treatment for the Pediatric Brain Tumor Medulloblastoma | HTML
This project involves an examination of the effect of the small molecule inhibitor 4SC-202 on the growth of the pediatric brain cancer medulloblastoma. The small molecule inhibitor 4SC-202 significantly inhibits the viability of the pediatric desmoplastic cerebellar human medulloblastoma cell line DAOY, with an IC50 = 58.1 nM, but does not affect the viability of noncancerous neural stem cells (NSC). 4SC-202 exposure inhibits hedgehog expression in the DAOY cell line. Furthermore, microarray analysis of human medulloblastoma patient tumors indicate significant upregulation of key targets in the Hedgehog signaling pathway and Protein Tyrosine Kinase (PTK7).

PDF] OTX2 directly activates cell cycle genes and inhibits differentiation in medulloblastoma cells | Semantic Scholar
It is demonstrated that OTX2 is essential in medulloblastoma and directly drives proliferation by regulation of cell cycle genes. The transcription factor OTX2 has been implicated as an oncogene in medulloblastoma, which is the most common malignant brain tumor in children. It is highly expressed in most medulloblastomas and amplified in a subset of them. To study the role OTX2 has in medulloblastoma we investigated the downstream pathway of OTX2. We generated D425 medulloblastoma cells in which endogenous OTX2 can be silenced by inducible shRNA. Silencing of OTX2 strongly inhibited cell proliferation and resulted in a neuronal‐like differentiation. Expression profiling of time courses after silencing showed a progressive change in gene expression for many cellular processes. Downregulated genes were highly enriched for cell cycle and visual perception genes, while upregulated genes were enriched for genes involved in development and differentiation. This shift is reminiscent of expression changes
The goal of the Johns Hopkins Brain Cancer Biology and Therapy Laboratory is to locate the genetic and genomic changes that lead to brain cancer. These molecular changes are evaluated for their potential as therapeutic targets and are often mutated genes, or genes that are over-expressed during the development of a brain cancer. The brain cancers that the Riggins Laboratory studies are medulloblastomas and glioblastomas. Medulloblastomas are the most common malignant brain tumor for children and glioblastomas are the most common malignant brain tumor for adults. Both tumors are difficult to treat, and new therapies are urgently needed for these cancers. Our laboratory uses large-scale genomic approaches to locate and analyze the genes that are mutated during brain cancer development. The technologies we now employ are capable of searching nearly all of a cancer genome for molecular alterations that can lead to cancer. The new molecular targets for cancer therapy are first located by l...arge ...

Medulloblastoma exome sequencing uncovers subtype-specific somatic mutations. | Broad Institute
Medulloblastomas are the most common malignant brain tumours in children. Identifying and understanding the genetic events that drive these tumours is critical for the development of more effective diagnostic, prognostic and therapeutic strategies. Recently, our group and others described distinct molecular subtypes of medulloblastoma on the basis of transcriptional and copy number profiles. Here we use whole-exome hybrid capture and deep sequencing to identify somatic mutations across the coding regions of 92 primary medulloblastoma/normal pairs. Overall, medulloblastomas have low mutation rates consistent with other paediatric tumours, with a median of 0.35 non-silent mutations per megabase. We identified twelve genes mutated at statistically significant frequencies, including previously known mutated genes in medulloblastoma such as CTNNB1, PTCH1, MLL2, SMARCA4 and TP53. Recurrent somatic mutations were newly identified in an RNA helicase gene, DDX3X, often concurrent with CTNNB1 mutations, ...

To identify targetable vulnerabilities, we employed inhibitor screening that revealed mTOR inhibitor hypersensitivity in the MYC-overexpressing medulloblastoma cell line, D341. Concomitant exome sequencing unveiled an uncharacterized missense mutation, TSC2A415V, in these cells. We biochemically demonstrate that the TSC2A415V mutation is functionally deleterious, leading to shortened half-life and proteasome-mediated protein degradation. These data suggest that MYC cooperates with activated kinase pathways, enabling pharmacologic intervention in these treatment ...

Developing new, less toxic approaches to treatment is critical to advancing therapy for medulloblastoma, the most common malignant brain tumor in children. While many medulloblastoma patients achieve long-term survival through combined radiation and chemotherapy, this treatment causes long-term neuro-cognitive impairment and significant risk of incurable recurrence. The early age of onset of medulloblastoma has prompted a growing consensus to examine the processes that support developmental brain growth as potential oncogenic mechanisms that may be targeted in novel therapies. Our recent work demonstrates that energy metabolism, DNA repair and control of apoptosis are developmentally regulated to support proliferation during cerebellar growth, and become co-opted in medulloblastoma formation. Our ongoing projects build on these observations, using mouse genetics and primary tumor modeling to learn:. ...
Cochlear implantation following treatment for medulloblastoma - Roland - 2009 - The Laryngoscope - Wiley Online Library
Treatment of pediatric medulloblastoma, the most common malignant tumor of the CNS in children, requires a combination of surgical excision, radiation therapy, and chemotherapy. Prior research has documented ototoxicity and middle ear disease in 25% to 90% of patients treated with multimodality therapy.5, 7, 11 At this institution, pediatric medulloblastoma patients receive a cumulative cisplatin dose of 300 mg, decreased from the standard of 600 mg. Early analysis suggests that this reduction may minimize ototoxic sequelae, however long-term data on SNHL is lacking. Further, the percentage of patients in this population that will ultimately qualify for cochlear implantation has not yet been documented.. Damage to the auditory system from chemotherapeutic agents, specifically platinum-based compounds, as well as radiation therapy is well documented. Cisplatinum ototoxicity is typically characterized by irreversible, bilateral, symmetric, high-frequency SNHL.5, 7 Ototoxicity can be related to ...
The germline variants in DNA repair genes in pediatric medulloblastoma: a challenge for current therapeutic strategies | BMC...
Assuming that the fundamental feature of cancer is genomic instability, functional defects of proteins which are responsible for maintenance of genome integrity by correcting DNA replication errors, should be carcinogenic. It is therefore not surprising that a number of cancer susceptibility genes encode key factors of DNA repair pathways. Recent comprehensive analysis of germline mutations in pediatric cancers pointed to DNA repair genes as the most commonly mutated genes, including TP53 and BRCA2 . It is also increasingly clear that defects in DNA repair genes may determine patients response to radio and chemotherapy [13, 16, 17]. In view of that we evaluated the potential association between DNA repair defects and treatment related toxicity as well as their potential role as a susceptibility factor for medulloblastoma.. The sequence analysis of two well-known repair genes MSH2 and RAD50 conducted in large cohort of 102 medulloblastoma patients revealed three new germline variants MSH2 ...
Researchers turn to single-cell analysis to understand a pediatric brain tumor
Investigators at St. Jude Childrens Research Hospital and Massachusetts General Hospital, alongside others, have revealed the cells of origin for specific subtypes of medulloblastoma, the most common malignant pediatric brain tumor.
3885 Medulloblastomas are malignant brain tumors that arise in the cerebellum in children. Aberrant activation of the Sonic Hedgehog (Shh) signaling pathway, which normally stimulates proliferation of granule neuron precursors (GNPs) during cerebellar development, induces tumors in mice that closely mimic human medulloblastomas. Shh-dependent medulloblastoma formation is enhanced by hyperactive insulin-like growth factor (IGF) signaling and ectopic expression of Myc oncogenes. This enhanced tumorigenesis stems from the sensitivity of GNPs to IGF and Myc levels in regulating proliferation. An emerging theme in cancer research is that oncogene-induced cell proliferation cannot initiate neoplastic transformation unless cellular programs that mediate apoptosis are disabled. We modeled the ability of the anti-apoptotic protein Bcl-2 to induce medulloblastoma in vivo using the RCAS/tv-a system, which allows postnatal gene transfer and expression in a cell type-specific manner. We targeted expression ...
Medulloblastoma outcome is adversely associated with overexpression of EEF1D, RPL30, and RPS20 on the long arm of chromosome 8 ...
Medulloblastoma is the most common malignant brain tumor of childhood. Improvements in clinical outcome require a better understanding of the genetic alterations to identify clinically significant biological factors and to stratify patients accordingly. In the present study, we applied cytogenetic characterization to guide the identification of biologically significant genes from gene expression microarray profiles of medulloblastoma. We analyzed 71 primary medulloblastomas for chromosomal copy number aberrations (CNAs) using comparative genomic hybridization (CGH). Among 64 tumors that we previously analyzed by gene expression microarrays, 27 were included in our CGH series. We analyzed clinical outcome with respect to CNAs and microarray results. We filtered microarray data using specific CNAs to detect differentially expressed candidate genes associated with survival. The most frequent lesions detected in our series involved chromosome 17; loss of 16q, 10q, or 8p; and gain of 7q or 2p. Recurrent

TY - JOUR. T1 - Ultrastructure of cerebellar hemangioblastoma - Some new observations on the stromal cells. AU - Shimura, T.. AU - Hirano, A.. AU - Llena, J. F.. PY - 1985/3. Y1 - 1985/3. N2 - Five cases of hemangioblastoma were studied by electron microscopy with particular attention to the stromal cells and their surrounding structures. Most of the stromal cells of the tumor had abundant clear cytoplasm containing rough endoplasmic reticulum, mitochondria, scattered fibrils, and large lipid inclusions. They were usually aggregated without intervening cells. In the perivascular areas, their sufaces facing the perivascular collagen were surrounded by basal lamina. Their apposed cell membranes had occasional adhesive devices. Occasional, long, apparently cylindrical processes of the stromal cell cytoplasm were observed in some cases. These processes contained intermediate filaments of undetermined nature and microtubules. In the border zone between the tumor and the surrounding brain, the stromal ...

Illuminating Medulloblastoma | AMI Meeting 2020
Medulloblastoma, a highly invasive tumour of the cerebellum, has one of the highest mortality rates of pediatric cancers. Metastatic cells are the leading cause of treatment failure and death in medulloblastoma patients. For over a century, scientists assumed that medulloblastoma metastases travel exclusively in cerebrospinal fluid; however, novel research shows that medulloblastoma can spread through the circulatory system as well. This new mechanism presents the first biological target for metastases; therefore, the dissemination of this research is critical to the development of therapies, disease management, and prognosis. An educational 3D animation can effectively disseminate this research, as well as increase awareness and interest in medulloblastoma. A story-driven narrative and emphasis on the use of visual metaphor will put the research in context by establishing why this research matters, what the future implications are, and how it is relevant to the audience.. ...
Laboratory for Childhood Brain Tumor Research. Medulloblastoma is the most common malignant brain tumor in children and one of the leading causes of death in this age group. Over one-third of children with medulloblastoma die within 5 years of diagnosis and the vast majority of survivors have significant neurological deficits due to the toxicity of combined surgery, radiation, and chemotherapy. To improve survival and minimize side effects of current therapy, a more detailed understanding of the biology of medulloblastoma will better characterize the disease and will aid in prognosis and in identification of novel treatments.. Cancer, in general, is a disease that is believed to originate sporadically from one or a few cells within a tissue. After a cell acquires genetic mutations over time, the cell then has a growth advantage over normal surrounding cells in the tissue, and has the potential to become cancerous. Current mouse models of cancer, including those for medulloblastoma, have been ...

Integrin Targeted Therapeutics
In chick chorioallantoic membrane (CAM) assays, injection of cilengitide into CAM vasculature prevented the growth of implanted U87MG glioma and DAOY medulloblastoma tumor fragments compared to the inactive peptide EMD135981. The inhibition of tumor growth was attributed to the anti-angiogenic activity of cilengitide as membrane vascularity surrounding the tumor graft was greatly decreased by cilengitide treatment as compared to the inactive control peptide . In animal models, cilengitide, as a single agent effectively inhibited the growth and proliferation of orthotopically implanted malignant glioma and medulloblastoma cell lines in nude mice. Daily treatment of established xenografts with 100-200 µg cilengitide significantly delayed tumor growth and prolonged survival compared to controls. The delayed tumor growth was accompanied by increases in CD31 and tumor doubling times, elevated apoptotic index and decreases in proliferative index and tumor vessel number and density . ...
STUDY OF EPIGENETIC DEREGULATION OF A NOVEL DEUBIQUITYLASE IN MEDULLOBLASTOMA | Archivio della ricerca dellUniversità degli...
A major goal of our work is to study medulloblastoma biology to facilitate the development of targeted therapy. Here, we have dissected the contribution of epigenetics to tumor development. Epigenetic perturbations are pharmacologically reversible and may have therapeutic potential. The RE1-Silencing Transcription Factor (REST) is an epigenetic modulator, and a repressor of neuronal differentiation genes. Its expression is significantly elevated in human medulloblastomas, and is associated with poor prognosis. REST is a driver of medulloblastoma in mouse orthotopic models. To understand RESTs contribution to tumor development, we created a novel genetically engineered mouse model in which REST transgene is conditionally elevated in the cerebellar granule progenitors (GNPs), the cells of origin of some medulloblastoma. Transgene induction caused GNP hyperproliferation, accompanied by a failure to express the cell cycle regulator-p27. Using genetic and biochemical approaches, we attributed the ...
INTRODUCTION. Seeding of cerebrospinal fluid (CSF) and leptomeninges by human tumor cells is associated with hydrocephalus and poor prognosis. CSF tumor spread is most commonly found in breast carcinoma in adults, and medulloblastoma in children. We evaluated breast cancer and medulloblastoma leptomeningeal (LM) tumor models as assessed by magnetic resonance imaging (MRI), histology, and survival. METHODS. MDA-MB231BR human breast carcinoma cells expressing HER2 (1 x 106 cells) and DAOY human medulloblastoma cells (1.5 x 106 or 5 x 106) were injected into the right lateral cerebral ventricle or the cisterna magna of adult female or male nude rats, respectively. Animals underwent weekly MRI (T2-weighted and T1-weighted with or without gadolinium). Ventricular volume and ventricular/cerebral ratio were measured as markers of hydrocephalus. Rat brains were harvested 1-4 weeks after tumor cell injection, or followed for survival, and coronal sections were evaluated by histology and ...

Pemetrexed and Gemcitabine Show Promise Against Aggressive Childhood Brain Tumor - The ASCO Post
The quest to improve survival of children with a high-risk brain tumor has led investigators at St. Jude Childrens Research Hospital to two drugs already used to treat adults with breast, pancreatic, lung, and other cancers. The study by Morfouace at al was published today in Cancer Cell. Researchers demonstrated that combination pemetrexed (Alimta) and gemcitabine was effective against mouse and human group 3 medulloblastoma cells. Of the four distinct medulloblastoma subtypes, patients with group 3 medulloblastoma have the worst prognosis.. Used together, pemetrexed and gemcitabine doubled life expectancy of mice with human group 3 medulloblastoma, compared to untreated mice. When pemetrexed and gemcitabine were combined with two chemotherapy drugs currently used to treat pediatric medulloblastoma, the mice lived even longer.. Study Details. The drugs were identified by screening the St. Jude library of 7,389 compounds looking for ones that targeted group 3 mouse tumor cells rather than ...

JCI - E-letters
Medulloblastoma, an aggressive cancer of the cerebellum, is among the most common pediatric brain tumors. Approximately one-third of medulloblastomas are associated with misactivation of the Hedgehog (Hh) pathway. GLI family zinc finger 2 (GLI2) coordinates the Hh transcriptional program; however, the GLI2 targets that promote cancer cell proliferation are unknown. Here, we incorporated a Gli2-EGFP allele into 2 different genetic mouse models of Hh-associated medulloblastoma. Hh signaling induced GLI2 binding to the Cdk6 promoter and activated Cdk6 expression, thereby promoting uncontrolled cell proliferation. Genetic or pharmacological inhibition of CDK6 in mice repressed the growth of Hh-associated medulloblastoma and prolonged survival through inhibition of cell proliferation. In human medulloblastoma, misactivation of Hh signaling was associated with high levels of CDK6, pointing to CDK6 as a direct transcriptional target of the Hh pathway. These results suggest that CDK6 antagonists may be ...

The role of immunohistochemistry in medullomyoblastoma - a case series highlighting divergent differentiation | Diagnostic...
To analyse the histo-morphology of cases of medullomyoblastoma and identifying its divergent differentiation. A retrospective review of all cases reported as medulloblastoma between the period of Jan 2000 to Dec 2006 was carried out on Hematoxylin and eosin (H & E) stained slides. The cases were screened on light microscopy for primitive neuroectodermal component of a medulloblastoma accompanied by areas of myoid differentiation, identified on the basis of presence of strap cells (indicating a clear skeletal muscle differentiation) and/or large anaplastic cells with vescicular nuclei and moderate to abundant amount of eosinophilic cytoplasm. All these cases were subjected to a panel of immunohistochemical stains, including Desmin, GFAP, NFP, HMB45, SMA, S100, CK and EMA. Ultrastructral analysis was done on tissue obtained from paraffin blocks in 2 cases. Male predominance (M:F = 5:1) was noted with an incidence of five percent of all cases of medulloblastoma (6 out of 120 cases) over a period of 6

Medulloblastoma arises from mutations occurring in stem/progenitor cells located in restricted hindbrain territories. Here we report that the mouse postnatal ventricular zone lining the IV ventricle also harbors bona fide stem cells that, remarkably, share the same molecular profile with cerebellar white matter-derived neural stem cells (NSC). To identify novel molecular mediators involved in medulloblastomagenesis, we compared these distinct postnatal hindbrain-derived NSC populations, which are potentially tumor initiating, with murine compound Ptch/p53 mutant medulloblastoma cancer stem cells (CSC) that faithfully phenocopy the different variants of human medulloblastoma in vivo. Transcriptome analysis of both hindbrain NSCs and medulloblastoma CSCs resulted in the generation of well-defined gene signatures, each reminiscent of a specific human medulloblastoma molecular subclass. Most interestingly, medulloblastoma CSCs upregulated developmentally related genes, such as Ebfs, that were shown ...

In the journal Cancer Research, UNC Lineberger researchers led by member Timothy R. Gershon, MD, PhD, report in the latest in a series of attempts to shut down the energy production machinery in medulloblastoma, the most common malignant brain tumor in children. The findings may help researchers identify a suitable therapeutic target within the sugar metabolism pathway, and provide clues to a scientific mystery surrounding the confounding way that some cancer cells get energy from sugar. ...
CLINICS | Article
1. Although surgery remains the major treatment for medulloblastoma, there is still controversy regarding the impact of resection on the prognosis of patients with medulloblastoma. Furthermore, in cases of adherent medulloblastoma to the brainstem, complete resection is extremely difficult. In addition, metastasis via the cerebrospinal fluid is common; thus, medulloblastoma patients often have a poor prognosis and a high mortality rate 2.. Clinically, the prognosis of patients with medulloblastoma is often determined according to the pathological type, which also provides a reference for the application of adjunctive therapies, such as radiotherapy and chemotherapy 3,4. Currently, the World Health Organization (WHO) classification system for medulloblastoma is based on histomorphology. However, patients with the same pathological type of medulloblastoma still have distinct genetic backgrounds. Therefore, the prognosis of patients with medulloblastoma may vary even within the same WHO ...

AU - Murata, Hideki. AU - Iwaki, Toru. AU - Sasaki, Tomio. PY - 2013/4/1. Y1 - 2013/4/1. N2 - The authors present an extremely rare case of a fibrotic nodule arising from the cerebellopontine (CP) angle. A 57-year-old male had suffered from hearing disturbance and tinnitus for several years. Computed tomography revealed a high-density mass in the left CP angle with little enhancement after intravenous administration of contrast media. Magnetic resonance imaging (MRI) showed a very hypointense mass on T2-weighted imaging. T1-weighted MRI with gadolinium revealed very faint, delayed enhancement of the tumor. The patient underwent surgical resection of the tumor. Histopathologically the lesion comprised entirely fibrotic tissue consisting of thick collagenous fibers and sclerosing blood vessels with a few ...

Y1 - 2018/3. N2 - Medulloblastoma is the most common malignant childhood brain tumor. The heterogeneous tumors are classified into four subgroups based on transcription profiles. Recent developments in genome-wide sequencing techniques have rapidly advanced the understanding of these tumors. The high percentages of somatic alterations of genes encoding chromatin regulators in all subgroups suggest that epigenetic deregulation is a major driver of medulloblastoma. In this report, we review the current understanding of epigenetic regulation in medulloblastoma with a focus on the functional studies of chromatin regulators in the initiation and progression of specific subgroups of medulloblastoma. We also discuss the ...
