The Value of Molecular Residual Disease Monitoring Based on ctDNA in Resected Pancreatic Cancer

Summary

The goal of this clinical trial is to explore the value of molecular residual disease (MRD) monitoring based on ctDNA in resected pancreatic cancer. The main questions it aims to answer are: * prognostic value of baseline MRD; * the role of MRD dynamic changes after treatment in guiding treatment. Peripheral blood derived from participants will be obtained for MRD test before adjuvant chemotherapy initiation and at the first imaging assessment after chemotherapy.

Eligibility

Inclusion Criteria:

* patients with pancreatic cancer who had undergone curative-intent surgery (R0 or R1 resection);
* both sexes, age ≥18 years old;
* ECOG performance status score ≤2;
* the expected survival time was ≥3 months.

Exclusion Criteria:

* a known diagnosis of pancreatic cancer other than ductal adenocarcinoma;
* treated with any systemic antitumor treatment before first-line chemotherapy onset;
* died or lost to follow-up within one month after the initiation of adjuvant chemotherpay;
* combined with other primary malignances.
