Gliosarcoma is a rare type of

neural brain cells. Gliosarcoma is a malignant cancer, and is defined as a glioblastoma consisting of gliomatous and sarcomatous components.[3] 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).[4] Because of a lack of specific and clear diagnostic criteria, the word "gliosarcoma" was frequently used to refer to glial tumours with mesenchymal properties,[5] such as the ability to make collagen and reticulin.[6]

It is estimated that approximately 2.1% of all glioblastomas are gliosarcomas. Although most gliomas rarely show metastases outside the

lymph nodes.[7]

They most commonly present in the temporal lobe[8][9] and frontal lobe.[10]

Pathogenesis

Early reports claimed that the hyperplastic blood vessels that are frequently present in high grade gliomas underwent neoplastic change to become the sarcomatous components.[6] Feigin's early reports components of perivascular sarcomatous and hyperplastic arteries in gliosarcoma offered evidence for the "collision tumor" hypothesis.[11] Also, Studies demonstrating the sarcomatous component's histological sensitivity to markers of vascular endothelium such factor CD34, von Willebrand factor, and VIII supported this theory.[12][13][14] An alternative view that has recently gained support suggests that both gliosarcoma components have a monoclonal origin, with the sarcomatous component deriving from abnormal differentiation of malignant gliomal mesenchyma. First, gliomatous and sarcomatous components were shown to have similar p53 alterations by Biernat and colleagues.[15] In both tumor regions, Reis and colleagues found similar nuclear accumulation of p53, deletion of p16, mutations of PTEN,and amplifications of CDK4.[16] Other scientists then noted that both gliosarcoma components had similar genetic changes and chromosomal abnormalities of the kind often seen in GBM.[17][18]

Clinical characteristics

Gliosarcoma is rare; incidence ranges from 1.8 to 2.8 percent lower than that of GBMs.[19] PGS affects persons in their 6th to 7th years of life, and it is much more frequent in males than in females (with 1.4-1.8:1 ratio).[19] Depending on where the tumor is located, the reported presenting signs and symptoms, such as aphasia, headaches, hemiparesis, seizures, and cognitive loss, are similar with those of a fast developing intracranial tumor. Many researchers have come to the conclusion that these tumors are clinically identical to GBM due to their clinical similarities.[20]

Imaging

On CT imaging, the lesions might show as Well-defined high-density lesion edges and homogeneous enhancement, replicating the meningioma appearance, or as lesions with large necrotic regions and GBM-like heterogeneous contrast enhancement.[21][22] Marked peritumoral edema is a characteristic and frequent hallmark of gliosarcomas observed on MRI.[19]

Metastasis

GBM and other cerebral gliomas rarely metastasize outside the brain. Numerous authors described incidences of metastatic foci that mixed gliomatous and sarcomatous components,[23][24] while others reported metastatic foci that were entirely composed of the sarcomatous component.[25][26][27] Most gliosarcoma extracranial metastases are found in the lung and liver, but there have been reports of metastases elsewhere as well,[28][29][30][31][32] including evidence of intramedullary metastases to the cervical spine.[33]

Treatment

Tumor removal, postoperative radiation treatment, and chemotherapy with nitrosureas, misonidazole, dacarbazine, temozolomide, doxorubicin , vincristine, cisplatin, mithramycin, ametophterin, thalidomide, or irinotecan have all been recorded as treatment options for gliosarcoma[34] and radiotherapy with temozolomide.[35]

Prognosis

PGS has a poor prognosis,[36] a prognosis of median survival of 4 months in untreated individuals.[37] The National Cancer Institute states that the relative five-year survival rate of gliosarcoma is only 5.6%.[2]
