- Gliosarkom je vzácný typ vysoce progresivního maligního gliomu, tumoru mozku nebo míchy pocházející z glie, podpůrné mozkové buňky. Obsahují také mezenchymální komponenty. Na rozdíl od většiny gliomů, u kterých se vyskytujé metastáze mimo mozek jen zřídka, gliosarkom metastazuje běžně do plic, žaludku, jater a lymfatických uzlin. Cca pouze 2% Glioblastomů tvoří gliosarkomy. (cs)
- Das Gliosarkom ist ein seltener, äußerst bösartiger (maligner), hirneigener Tumor. Er weist wie das ihm ähnliche Glioblastoma multiforme Ähnlichkeiten mit den Gliazellen (Astrozyten) auf. Als Variante des Glioblastoms wird das Gliosarkom wegen seiner sehr schlechten Prognose in der WHO-Klassifikation der Tumoren des zentralen Nervensystems als Grad IV eingestuft. (de)
- Gliosarcoma is a rare type of glioma, a cancer of the brain that comes from glial, or supportive, brain cells, as opposed to the neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous components. Primary gliosarcoma (PGS) is classified as a grade IV tumor and a subtype of glioblastoma multiforme in the 2007 World Health Organization classification system (GBM). Because of a lack of specific and clear diagnostic criteria, the word "gliosarcoma" was frequently used to refer to glial tumours with mesenchymal properties, such as the ability to make collagen and reticulin. It is estimated that approximately 2.1% of all glioblastomas are gliosarcomas. Although most gliomas rarely show metastases outside the cerebrum, gliosarcomas have a propensity to do so, most commonly spreading through the blood to the lungs, and also liver and lymph nodes. They are most commonly present in the temporal lobe and frontal lobe. (en)
- El gliosarcoma es un tipo raro de glioma, un tumor cerebral que procede de la glía. La glía son las células del cerebro cuya función es servir de sostén a las células cerebrales principales que son las neuronas. (es)
- Il gliosarcoma è una variante istologica del glioblastoma caratterizzata da una struttura tissutale bifasica, con aree che mostrano alternativamente differenziazione gliale e mesenchimale. Presenta sintomi e segni identici al glioblastoma ordinario. Metodica di diagnosi e trattamento sono gli stessi. Dubbi su migliorie rispetto a quest'ultimo riguardo alla prognosi. (it)
