K-<i>ras</i>Oncogene Activation as a Prognostic Marker in Adenocarcinoma of the Lung

Abstract excerpt

BACKGROUND: The capability of activated oncogenes to induce malignant transformation of immortalized cells in vitro has suggested that they have a similar role in the pathogenesis of human tumors. We previously found that activation of the K-ras oncogene by a point mutation in codon 12 occurs in about one third of human lung adenocarcinomas. METHODS: We studied the clinical importance of this oncogene-activation...
