Significance of KRAS mutation testing in biliary brushing cytology specimens: A 10-year retrospective review.

Cancer cytopathology - 1 Jul 2022

Sun Tong, Zuo Tao, Hui Pei, Cai Guoping

Abstract excerpt

BACKGROUND: Biliary strictures can be caused by benign and malignant conditions. A biliary duct brushing diagnosis can be challenging because of low cellularity and overlapping morphology among different entities, leading to a variable reported sensitivity. This study aimed to assess the value of KRAS mutation testing in adding cytological diagnosis of biliary duct brushings. METHODS: With institutional review...
