In the present study, the diagnosis was incorrectly made for five cases of gliomas, where two cases of Grade III Astrocytoma were wrongly diagnosed as cerebral abscess and Metastasis respectively, one case of Grade II astrocytoma was wrongly diagnosed as acute infarct, one case of Oligoastrocytoma was wrongly diagnosed as Meningioma, one case of GBM was wrongly diagnosed as Choroid plexus carcinoma.
Estimated 5-year survival was 60% (95% CI, 48%-72%) for biopsy and 74% for (95% CI, 64%-84%) early resection.3 Majority of the patients included were found to have grade II astrocytoma. This was further studied in their post hoc analysis, revealing similar results with early surgery.
Figure 3 shows fused images (of grade II astrocytoma class) obtained by using different techniques.
Tumors or cysts treated include a pineal cyst, lateral ventricle arachnoid cysts (n = 3), a large colloid cyst, a benign mixed astroglial cyst, low-grade gliomas (n = 4) (1 myxopapillary ependymoma, 1 WHO grade II astrocytoma, 1 pilocytic astrocytoma, and 1 subependymal giant cell astrocytoma (SEGA)), a dysembryoplastic neuroepithelial-like tumor (DNET), an epidermoid tumor, an immature teratoma, a craniopharyngioma, a giant pituitary macroadenoma with intraventricular extension, and a pineal parenchymal tumor (intermediate differentiation).
An excision biopsy showed a grade II astrocytoma. Subsequent radiotherapy localised to the lesion and base of the brain was completed.
We hypothesized that any peptide peaks that progressively change with increasing malignancy (control [right arrow] grade II astrocytoma [right arrow] anaplastic astrocytoma [right arrow] GBM) are potential survival biomarkers for patients with GBM.
Microscopic examination revealed a grade II astrocytoma with infiltration of the cerebral cortex (Figure, E).
