Topographic analysis of K- ras mutations in histologically normal lung tissues and tumours of lung cancer patients.

Abstract excerpt

Mutations in the K- ras gene are very common in lung tumours and are implicated in the development of lung cancer, but the timing of their occurrence remains poorly understood. We investigated K- ras mutations in cell samples microdissected by laser capture microscopy at multiple sites from lung tissue sections representing tumour tissue and matched histologically normal tissue obtained from 48 lung cancer...
