Pancreatic cancer is considered a rare form of cancer with about 277,000 new cases diagnosed in 2008 world-wide, which is about 2.5% of all forms of cancer. However, pancreatic cancer is m...
This first-in-human dose-escalation study is to characterize the safety, tolerability, pharmacokinetics and pharmacodynamics of LDE225 given orally on a daily dosing schedule in patients w...
The aim of the study was to improve local control and long-term survival in children with medulloblastoma, reduce the side effects of treatment and improve quality of life.
This phase II trial is studying giving radiation therapy together with combination chemotherapy after surgery to see how well it works in treating children with newly diagnosed medulloblas...
This phase II trial is studying how well vismodegib works in treating adult patients with recurrent or refractory medulloblastoma. Vismodegib may slow the growth of tumor cells and may be ...
While the preponderance of morbidity and mortality in medulloblastoma patients are due to metastatic disease, most research focuses on the primary tumor due to a dearth of metastatic tissue samples an...
Medulloblastoma is the most common malignant paediatric brain tumour and current therapies often leave patients with severe neurological disabilities. Four major molecular groups of medulloblastoma ha...
Medulloblastoma is a malignant tumor of the posterior fossa and is predominantly seen in children less than 15 years of age. This tumor is uncommon in adults, especially those older than 40 years, and...
Medulloblastoma is associated with rare hereditary cancer predisposition syndromes; however, consensus medulloblastoma predisposition genes have not been defined and screening guidelines for genetic c...
The current consensus recognizes four main medulloblastoma subgroups (wingless, Sonic hedgehog, group 3 and group 4). While medulloblastoma subgroups have been characterized extensively at the (epi-)g...
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)
A patched receptor that may function redundantly with the PATCHED-1 RECEPTOR to modulate hedgehog signaling. It may also play a role in epidermal development and as a TUMOR SUPPRESSOR PROTEIN. Mutations in the patched-2 gene are associated with BASAL CELL NEVUS SYNDROME; CARCINOMA, BASAL CELL; and MEDULLOBLASTOMA.
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).
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.
