Monitoring blood markers to predict colorectal cancer recurrence after surgery

A Prospective Multicentre Clinical Study of Dynamic Monitoring of Plasma ctDNA Methylation Markers to Predict Recurrence of Colorectal Cancer After Complete Resection of Peritoneal Metastases

Observational Fudan University · NCT06903325

This study is testing if blood markers can help predict if colorectal cancer will come back after surgery in patients who have had their cancer completely removed.

What this trial studies

This clinical trial investigates the role of postoperative plasma ctDNA methylation markers in predicting the recurrence of colorectal cancer in patients who have undergone complete resection of peritoneal metastases. It involves collecting blood samples from participants to analyze ctDNA methylation status and correlating these findings with clinical outcomes over a follow-up period of at least 24 months. The study aims to enhance understanding of how these biomarkers can inform recurrence-free survival rates in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with colorectal adenocarcinoma who have undergone R0/R1 resection and have peritoneal metastasis.

Not a fit: Patients with other primary malignancies, severe comorbidities, or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable method for predicting cancer recurrence, allowing for timely interventions and improved patient outcomes.

How similar studies have performed: While the specific approach of using ctDNA methylation markers is relatively novel, similar studies have shown promise in using ctDNA for monitoring cancer recurrence.
