K-ras gene mutation in the diagnosis of ultrasound guided fine-needle biopsy of pancreatic masses.

Abstract excerpt

AIM: To investigate the utility of K-ras mutation analysis of ultrasound guided fine-needle aspirate biopsy of pancreatic masses. METHODS: Sixty-six ultrasound guided fine-needle biopsies were evaluated by cytology, histology and k-ras mutation. The mutation at codon 12 of the k-ras oncogene was detected by artificial restriction fragment length polymorphisms using Bst NI approach. RESULTS: The presence of...
