Cytomorphologic Characteristics of Next-Generation Sequencing-Positive Bile Duct Brushing Specimens

The eJournal is an online pathology journal club that reviews current articles from a peer-reviewed cytopathology Journal.

Participants will be able to review the journal article, commentary and webinar from the contributing author. This is a great self-assessment, teaching and continuing education tool.

Target Audience

This educational activity is designed for pathologists, cytopathologists, cytotechnologists, students and other members of the cytopathology community.

Learning Objectives

  • Recognize and analyze the challenges associated with interpreting cytologic specimens of Bile Duct Brushings (BDBs), including the complexity of overlapping morphologic features between non-neoplastic, low-grade neoplastic, and malignant bile duct strictures.
  • Establish a correlation between specific cytomorphologic characteristics observed in BDB samples and the presence of genetic mutations associated with high-risk strictures, using Next-Generation Sequencing (NGS) as a diagnostic tool.
  • Evaluate the potential impact and clinical implications of incorporating NGS into BDB cytology algorithms, considering the improved sensitivity and diagnostic accuracy in identifying high-risk and malignant strictures.
