Dr. Chien-Jui Huang is an Assistant Professor and Attending Physician in the Division of Gastroenterology and Hepatology at National Cheng Kung University Hospital. She received her MD from National Cheng Kung University in 2012 and her PhD from the Institute of Clinical Medicine, College of Medicine, NCKU in 2021. As a gastroenterologist and interventional endoscopist, her clinical practice centers on advanced therapeutic digestive endoscopy, GI medical oncology, and the diagnosis and treatment of hepato-pancreato-biliary disease, including endoscopic ultrasound with fine-needle biopsy (EUS-FNB) and ERCP.
Dr. Huang's research addresses a central unmet need in pancreatic and biliary tract cancer: the lack of accurate, real-time tools to monitor disease and guide treatment. Her work is unified by the theme of liquid biopsy — minimally invasive blood- and fluid-based biomarkers to detect, monitor, and prognosticate disease that is difficult to track by conventional imaging or serum markers.
The core of this work is circulating cell-free DNA (cfDNA/ctDNA) in pancreatic ductal adenocarcinoma. Addressing the limitations of CA19-9, her research showed that quantitative cfDNA monitoring can predict new distant metastasis earlier than routine CT imaging, as an independent predictor of progression-free and overall survival. By cross-referencing KRAS G12 variants and circulating tumor cell counts, she confirmed the tumor origin of this signal, establishing cfDNA quantification as a practical tool for monitoring during chemotherapy and, prospectively, for guiding surgical decisions after neoadjuvant therapy.
Her interests extend across complementary fronts that reinforce this focus: EUS-guided tissue acquisition optimized for molecular diagnostics, bile-based liquid biopsy in cholangiocarcinoma, and the perioperative and systemic management of pancreatic cancer. Her methodological toolkit spans next-generation sequencing, circulating tumor cell characterization, and survival modeling.
She works within NCKUH's multidisciplinary pancreaticobiliary cancer group alongside colleagues including Yan-Shen Shan, Chia-Jui Yen, Wei-Lun Chang, and Ying-Jui Chao, and is actively involved as an investigator in numerous Phase I/II and Phase III clinical trials in pancreatico-biliary and upper gastrointestinal cancers.
Pancreatic ductal adenocarcinoma is a systemic disease even when it appears anatomically localized, and surgery alone is rarely curative. Perioperative systemic therapy has therefore become central to curative-intent management. This lecture outlines the modern framework for treating resectable and borderline resectable disease and the principles that guide clinical decision-making.
After upfront resection, multi-agent adjuvant chemotherapy is the established standard for fit patients, yet a substantial proportion never complete it — a limitation that has motivated efforts to deliver systemic therapy before surgery. For clearly resectable disease, whether a neoadjuvant approach improves outcomes over upfront surgery remains unresolved, with several pivotal randomized trials awaited. For borderline resectable disease, neoadjuvant chemotherapy is now standard, while the role of radiotherapy has become increasingly selective.
Looking ahead, treatment is shifting from an anatomy-based to a biology-informed model. Germline and somatic profiling, CA19-9 dynamics, and circulating tumour DNA / minimal residual disease are positioned to individualize the intensity, sequencing, and selection of perioperative therapy. The lecture closes by considering how these advances can be translated into everyday clinical practice.
