Establishment of a Predictive Model for Immunotherapy Response in Pancreatic Cancer

Condition(s) studied

Investigational drug(s) / intervention(s)

Sample Collection: Prior to treatment initiation (baseline), collect tissue specimens from the patient's pancreatic cancer or liver metastases via ultrasound-guided biopsy. Simultaneously collect one tube of EDTA-anticoagulated peripheral blood, one tube of clotting-anticoagulant peripheral blood, and one stool sample. Collect peripheral blood and stool samples at key time points including initial assessment, second assessment, and disease progression. Plasma and serum were extracted from the two tubes of peripheral blood. Concurrently, clinical and pathological parameters (age, sex, tumor TNM staging, pathological findings, etc.) and follow-up prognostic information (recurrence status, survival time) were recorded.

Study summary

This project aims to establish a single-center, prospective, observational clinical cohort for pancreatic cancer immunotherapy. It plans to enroll 100 patients with advanced pancreatic cancer, collecting tumor tissue sections, plasma, serum, and fecal samples. Through multi-omics analysis including proteomics, metabolomics, and microbiomics, the project will develop predictive models for immunotherapy response.

Eligibility

Primary outcome measure(s)

• Objective Best Tumor Response — 12 months
  Response using Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Complete Response=disappearance of all target lesions; Partial Response=30% decrease in sum of longest diameter of target lesions; Progressive Disease=20% increase in sum of longest diameter of target lesions; Stable Disease=small changes that do not meet above criteria.
• Overall Survival — 60 months
  Overall survival is the duration from diagnosis to death. For patients who are alive, overall survival is censored at the last contact.
