PURPOSE Phase I-II studies indicate that imatinib is active in glioblastoma multiforme. To better understand the molecular and clinical effects of imatinib in glioblastoma multiforme, we conducted a neoadjuvant study of imatinib with pretreatment and posttreatment biopsies. EXPERIMENTAL DESIGN Patients underwent a computerized tomography-guided biopsy of(More)
Evidence from many investigators has shown that mutations in the first exon of K- ras gene occur at elevated frequencies in lung, pancreatic and colon carcinoma and seem to be of prognostic importance. The aim of this study was to develop an effective method for the detection of K- ras mutations in codons 12 and 13 in non-small-cell lung cancer (NSCLC)(More)
