Abstract Text Current chemotherapy regimens for cholangiocarcinoma (CCA) yield poor outcomes, with a median overall survival of <12 months. Recent data on the genomic landscape of CCAs have created opportunities for targeted therapy. Yet, data regarding its efficacy are scarce. We aimed to describe the genomic landscape of a CCA patient cohort using next-generation sequencing (NGS), focusing on the ERBB/EFGR pathway and assessing response to anti-HER2 agents.Tissue samples of intrahepatic CCA (IHCC) and extrahepatic CCA (EHCC) underwent NGS for somatic aberrations. The clinical outcomes for patients treated with anti-HER2 agents were evaluated.A total of 1,863 CCA cases (1,615 IHCCs and 248 EHCCs) underwent NGS, and they revealed a high prevalence of ERBB alterations (IHCC, 4.2%; EHCC, 9.7%). Among these, 23.8% of the IHCCs and 53.6% of the EHCCs had a point mutation in ERBB2, and 66.6% of the IHCCs and 41.2% of the EHCCs had ERBB copy number amplification. Three EHCC patients were diagnosed at our institute with ERBB/EGFR aberrations; 2 patients were treated with neratinib and 1 patient with a chemotherapy-trastuzumab combination. All 3 achieved disease stabilization and a clinical benefit. One patient underwent a liquid biopsy before and after 3 months of treatment, demonstrating disappearance of the ERBB2 clone and emergence of a Myc-mutated clone after treatment.The genomic landscape of CCAs may harbor targetable alterations, especially in the ERBB/EGFR pathway. These alterations may have clinical significance in everyday practice.

Filtering

  • Case insensitive filtering will display rows if any text in any cell matches the filter term
  • Use simple literal full or partial string matches
  • Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
  • Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

  • Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
