  Glioblastoma multiforme (GBM) is the most aggressive form of glioma. Genetic analysis of GBM tumorigenesis has identified several alterations in particular EGFR and PTEN genes. The purpose of the present study was to analyze the frequency and distribution of EGFR/PTEN mutations in GBM and to determine their relationship with different clinicopathological characteristics. The paired tumor and adjacent normal tissue specimens of 40 consecutive patients with GBM were examined and DNA preparations were evaluated for the occurrence of EGFR/PTEN gene mutations by PCR-SCCP and DNA sequencing. In total, 20 of 40 (50%) GBM tumours had mutation of either an EGFR or PTEN. EGFR gene mutation was present in 13 (32.5%) and PTEN gene mutations in 07 of 40 (17.5%) patients. Both EGFR/PTEN mut..
