French Assessment of MRD by Liquid Biopsies in PDAC Patients (FRENCH.MRD.PDAC)
The overall objective of this GUIDE.MRD consortium is to confirm that ctDNA detected after curative intended treatment for PDAC is a marker of residual disease and for risk-of-recurrence, and applicable in clinical practice.

Primary objective To confirm that ctDNA analyses performed after PDAC treatment can identify patients with a high risk-of-recurrence.

Specifically, the investigators want to determine the association between disease-free survival (DFS) and ctDNA detection status after

curative-intended surgery and
adjuvant chemotherapy.

FRENCH.MRD.PDAC is the French study of the european GUIDE.MRD project
