Diversity of cytogenetic and pathohistologic profiles in glioblastoma.

We present a small series of patients with primary glioblastoma multiforme (GBM), and combine individual genetic data with pathohistologic characteristics and clinical outcome. Eighteen patients (12 men, 6 women, median age 51 years) with histologically proven GBM underwent surgical debulking followed by radiotherapy. Fifteen received concomitant chemotherapy.
