What the trial is, and whether it could suit you
The goal of this prospective observational study is to learn about the clinical utility of dynamic ctDNA-based Minimal Residual Disease (MRD) monitoring in patients with borderline resectable pancreatic cancer undergoing neoadjuvant therapy. The main questions it aims to answer are:
1. Does MRD negativity correlate with improved surgical outcomes (R0 resection rates) and long-term survival (Disease-Free Survival \[DFS\] / Overall Survival \[OS\])?
2. Can serial MRD status assessments guide optimal neoadjuvant therapy duration? Participants (n=119) will be adults aged 18-75 years with histologically confirmed pancreatic cancer meeting NCCN criteria for borderline resectable/high-risk resectable/locally advanced disease, deemed eligible for neoadjuvant therapy by a multidisciplinary team (MDT) and with ECOG performance status ≤1. Patients with distant metastasis, prior anticancer therapy,
