Blood-based prediction and early detection of pancreatic cancer recurrence after tumor resection

Key Points

This research aims to improve the early detection and prediction of pancreatic cancer recurrence post-tumor resection.
Analyzed blood samples to detect biomarkers associated with recurrence.
Monitored CA19-9 levels post-surgery in patients with pancreatic ductal adenocarcinoma.
Used imaging techniques like CT for regular follow-up examinations.
Reported a high rate of recurrence within 2 years after surgery.
Identified CA19-9 as a key biomarker for monitoring post-surgery recurrence.
Demonstrated the potential of blood-based methods for early detection.

Abstract

The 5-year survival rate of patients with pancreatic ductal adenocarcinoma (PDAC) is < 8%. The best therapeutic option for PDAC is tumor resection. However, most patients experience recurrence within 2 years after surgery11. Postoperative monitoring includes CT imaging and determining CA19-9
