Hepatobiliary and Pancreatic Tumor Biobank

Cholangiocarcinoma, Hepotacellular Carcinoma, Pancreatic Cancer

This study aims to establish a hepatobiliary and pancreatic tumor biobank at the Second Affiliated Hospital of Zhejiang University School of Medicine. The biobank will systematically collect and store human biological samples, such as blood, tissue, bile, and other body fluids, together with relevant clinical and follow-up information from patients with hepatobiliary and pancreatic tumors, benign hepatobiliary and pancreatic diseases, and selected healthy volunteers. The collection of samples will be performed without changing routine medical care and will not involve any experimental treatment or additional invasive procedures for research purposes. Biological samples will be obtained during standard clinical diagnosis and treatment, or from remaining specimens after routine clinical use. All samples and data will be coded and stored according to ethical and legal requirements to protect participants' privacy. The biobank is intended to serve as a long-term research resource to support future basic, translational, and clinical research on hepatobiliary and pancreatic diseases, with the goal of improving understanding of disease mechanisms and advancing medical research in this field.

This study is designed as a single-center, observational biobank project conducted at the Second Affiliated Hospital of Zhejiang University School of Medicine. The primary purpose of this study is to establish and maintain a structured hepatobiliary and pancreatic tumor biobank that integrates biological specimens with corresponding clinical and follow-up data for long-term research use. Eligible participants include adult patients diagnosed with hepatobiliary and pancreatic malignant tumors, patients with benign hepatobiliary and pancreatic diseases, and selected healthy volunteers. Enrollment is based on predefined inclusion and exclusion criteria, and participation requires written informed consent unless otherwise approved by the institutional ethics committee for retrospective samples. Biological specimens collected in this biobank may include peripheral blood, tumor and adjacent non-tumor tissue, bile, and other body fluids. Sample collection is performed without altering routine medical care and does not involve experimental treatments or additional invasive procedures for research purposes. Specimens are obtained during standard diagnostic or therapeutic procedures or from remaining clinical specimens after routine use. Clinical information associated with each participant, such as demographic characteristics, diagnosis, pathology findings, treatment details, and follow-up outcomes, is systematically collected from existing medical records and follow-up systems. All data and specimens are coded and de-identified prior to storage to ensure participant confidentiality. The biobank is intended to function as a long-term research infrastructure. Biological samples and data may be used in future ethically approved basic, translational, or clinical studies related to hepatobiliary and pancreatic diseases. Each secondary use of samples or data will require appropriate ethical review and approval in accordance with institutional and regulatory requirements.
