Diagnostic utility of K-ras mutational analysis on bile obtained by endoscopic retrograde cholangiopancreatography.

Gastrointestinal endoscopy - 1 Oct 1995

Abstract excerpt

BACKGROUND: Because K-ras oncogene mutations are present in more than 90% of pancreaticobiliary tumors, we tested prospectively whether K-ras mutational analysis of bile samples obtained during ERCP was superior to conventional bile cytology for diagnosis of malignancy. METHODS: Bile samples from 20 patients undergoing ERCP for evaluation of jaundice were examined by both cytologic study and the polymerase chain...
