Join moderator Caroline DiCristo, PharmD, Associate Medical Director – Zanidatamab of Jazz Pharmaceuticals and GI Oncologist Dr. Umair Majeed of Mayo Clinic in Jacksonville for the first installment of the Advancing Care in GI and Biliary Tract Cancers podcast series, focused on biliary tract cancers.
The first in the series, this episode provides a comprehensive overview of biliary tract cancers, including intrahepatic and extrahepatic cholangiocarcinoma and gallbladder cancer, highlighting their rarity, evolving epidemiology, and complex biology. Dr. Majeed reviews key risk factors such as chronic liver inflammation, primary sclerosing cholangitis, viral hepatitis, gallstones, and metabolic-associated liver disease, emphasizing the importance of early suspicion and multidisciplinary awareness.
Diagnosis & Staging Complexity: The discussion outlines the critical steps required to confirm diagnosis and stage disease accurately:
• Imaging Workup: The role of CT chest, MRI abdomen, and PET imaging in determining resectability and metastatic spread.
• Tissue Acquisition Challenges: Endoscopic approaches, biopsy considerations, and the importance of avoiding peritoneal violation in transplant-eligible hilar cholangiocarcinoma.
• Tumor Markers: Use of CA 19-9 for monitoring disease trends.
• Multidisciplinary Coordination: Collaboration among oncology, gastroenterology, surgery, radiology, pathology, and hepatology teams to optimize patient care.
First-Line Treatment & Molecular Testing:
Dr. Majeed discusses the current standard of care for metastatic disease, including chemoimmunotherapy based on the TOPAZ-1 and KEYNOTE-966 trials, and underscores the critical role of next-generation sequencing in identifying actionable mutations.
HER2 as an Emerging Target:
The episode also introduces HER2 as a clinically meaningful biomarker in biliary tract cancers, particularly in gallbladder and extrahepatic subtypes. Dr. Majeed reviews testing strategies, the importance of immunohistochemistry and confirmatory FISH testing, and emerging second-line HER2-directed therapies that may extend survival while offering chemotherapy-free intervals for appropriate patients.
Tune in for an in-depth discussion on the evolving diagnostic and therapeutic landscape of biliary tract cancers and the essential role of precision medicine and multidisciplinary collaboration in improving outcomes
