Medulloblastoma is the most common pediatric central nervous system malignancy and the most common primary tumor of the posterior fossa in children. Medulloblastomas arise in either the vermis or the lateral cerebellar hemispheres from neuronal stem cells in these locations.

Here is the microscopic appearance of a medulloblastoma with small round blue cells. Medulloblastomas tend to be aggressive neoplasms. They tend to arise in

Subtype 3 (group 3): histology of subtype 3 tumours is either classic or large-cell/anaplastic and these are frequently metastasised at the time of diagnosis. On a molecular level, medulloblastomas are heterogeneous and can be divided into four distinct subgroups with divergent tumor cell histology, genetics, clinical behavior, and patient outcomes. The histopathology and molecular pathogenesis of medulloblastoma will be reviewed here. All four groups show relatively distinct variation in demographics, histology, genetic profile, and clinical outcome . For a detailed comprehensive review on the molecular subgroups of medulloblastoma, see the consensus paper by Taylor et al. . Medulloblastoma is a primary central nervous system (CNS) tumor.

Medulloblastoma with rhabdomyoblastic differentiation - several images (upmc.edu). Subtypes Histologically defined. Classic medulloblastoma (~85% of all medulloblastomas). Variants of medulloblastoma (~15% of all medulloblastomas together): Anaplastic / Large cell variant.

As noted by the authors, the prognosis of patients with medulloblastoma has classically been dependent on the Chang M stage,[1] and to some degree on tumor histology, as some studies have indicated a better or worse prognosis with desmoplastic[2,3] vs large-cell/anaplastic histology,[4] respectively.

Molecular Imaging and Biology, 2011. Joel Michalek Desmoplasia in medulloblastoma is often diagnosed in adult patients and was repeatedly associated with improved results. Today, all medulloblastoma patients receive intensive multimodal treatment including surgery, radiotherapy and chemotherapy. This study was set up to investigate treatment outcome and prognostic factors after radiation therapy in patients with desmoplastic medulloblastomas. 2014-10-28 As advances in the molecular and genetic profiling of pediatric medulloblastoma evolve, associations with prognosis and treatment are found (prognostic and predictive biomarkers) and research is directed at molecular therapies.

2014-05-04 Medulloblastoma generally affects patients in the first two decades of life, accounting for about a fifth of all intracranial neoplasms of childhood.

The resulting data was statistically analyzed using event-free and overall patient survival as endpoints. Medulloblastoma is the most common pediatric central nervous system malignancy and the most common primary tumor of the posterior fossa in children. Medulloblastomas arise in either the vermis or the lateral cerebellar hemispheres from neuronal stem cells in these locations. Histologically, they are highly cellular tumors with dark staining, round or oval nuclei. On a molecular level, medulloblastomas are heterogeneous and can be divided into four distinct groups with divergent tumor cell histology, genetics, clinical behavior, and patient outcomes. 2014-05-04 Medulloblastoma generally affects patients in the first two decades of life, accounting for about a fifth of all intracranial neoplasms of childhood. 2015-01-14 Medulloblastoma, histologically defined.
