The goal of this observational study is to learn about early recurrence after curative-intent surgery for pancreatic cancer. The main questions it aims to answer are:
* How often does early recurrence (within 12 months after surgery) occur?
* When does it happen, and at which anatomical sites (liver, lung, local, peritoneum)?
* How is recurrence detected (imaging or tumor markers)?
Adults with histologically confirmed pancreatic ductal adenocarcinoma who undergo curative-intent resection without distant metastases will be enrolled. Participants will be followed according to routine clinical care at each hospital, typically with imaging and CA19-9 blood tests. No study-specific interventions are required.
