Cholangiocarcinoma (CCA) represents approximately 3% of all gastrointestinal cancers and is a highly heterogeneous and aggressive malignancy originating from the epithelial cells of the biliary tree. CCA is classified by anatomical location into intrahepatic (iCCA), extrahepatic (eCCA), gallbladder cancer (GBC), and ampullary cancers. Although considered a rare tumor, CCA incidence has risen globally, particularly due to the increased diagnosis of iCCA.

Purpose: Biliary tract cancers (BTCs) include intrahepatic cholangiocarcinoma (ICC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancers. BTCs have a number of genomic alterations, including isocitrate dehydrogenase 1 () mutations, fibroblast growth factor receptor 2 () rearrangements, and amplifications. Therapies targeting these alterations have shown clinical benefit in patients with BTCs in the United States.

The molecular pathological examination of solid tumors is essential not only for supporting histological diagnosis but also for detecting hereditary variations and predictive biomarkers. Analyzing predictive markers is fundamental to personalized cancer therapy, directly affecting patient care through pathological testing. These analyses employ both traditional immunohistochemical staining methods and molecular genetic techniques.

In this article, we present genomic analyses of tissue biopsies and circulating tumor DNA (ctDNA) from patients with 1 of nearly 20 tumor types treated with futibatinib in the phase I/II FOENIX study.
Patients And Methods: Eligible patients included those with ctDNA samples collected per protocol at baseline and/or progression on futibatinib in the phase Ib portion of the study for FGF/FGFR-altered advanced solid tumors or the phase II portion of the study for FGFR2 fusion/rearrangement-positive cholangiocarcinoma.
Molecular testing of gastrointestinal tumours - current status and future prospects.

December 2024
In addition to the histological diagnosis, grade and stage, predictive testing plays a crucial role in gastrointestinal tumours today. This is mainly used to identify molecular targets for modern cancer therapy. In esophageal and gastric cancers, HER2 expression and amplification, mismatch repair (MMR) system protein deficiency and PD-L1 expression are tested routinely.
