Herein, we report on comparative genomic hybridization (CGH) and immunohistochemical (IHC) assessment of EGFR, PTEN, p53, and MIB-1 expression in 13 oligodendrogliomas (10 WHO grade II, 3 WHO grade III), one oligoastrocytoma (WHO grade III) and 23 high-grade astrocytomas (3 WHO grade III, 20 glioblastoma multiforme).

Most of them demonstrate that MIB-1 LI differentiates well between diffuse astrocytomas WHO grade II (AII) and anaplastic astrocytomas (AA) and between AII and glioblastomas (GM), but not between AA and GM.

We prepared polyclonal anti-survivin serum to establish a survivin index for stained sections, using an immunohistochemical procedure, according to the method used for scoring MIB-1 index, and then stained 29 paraffin-embedded sections from surgical specimens of 29 patients who were classified into three grades of World Health Organization with the mean age of low grade astocytoma (grade II) being 34.7; anaplastic astrocytoma (grade III), 48.8; and glioblastoma multiform (grade IV), 58.4.

Our objectives in this study were to verify the presence of apoptosis, blc-2, p53, and the proliferative index (MIB-1), through immunohistochemistry, in 30 glioblastomas obtained by surgical resection between August 2000 and August 2001, as well as correlations between those immunohistochemical variables and the patient's age and survival time.

A total of 63 astrocytic tumors [27 glioblastomas (GBM), 19 anaplastic astrocytomas (AA), 17 low-grade astrocytomas (LGA)] and 5 normal brain tissues were immunohistochemically stained with antibodies to TP, vascular endothelial growth factor (VEGF), p53, MIB-1, and factor-VIII-related antigen.

In contrast, gemistocytes showed a significantly lower proliferating activity than the mean of all tumor cells, with a mean MIB-1 LI of 0.5% versus 2.6% in low-grade astrocytomas, 1.5% versus 11.6% in anaplastic astrocytoma, and 1.7% versus 16.6% in glioblastomas (p < 0.0001).
