In plain words

What the trial is, and whether it could suit you

The goal of this clinical trial is to explore the predictive effect of postoperative plasma ctDNA methylation status on postoperative recurrence free survival (RFS) of colorectal cancer patients with peritoneal metastasis after R0/R1 resection. The main questions it aims to answer are: Preoperative and postoperative plasma ctDNA methylation detection (ColonAiQ) was performed in patients with peritoneal metastasis from colorectal cancer who underwent R0/R1 resection. Clinical information of patients was collected to explore the predictive effect of postoperative plasma ctDNA methylation status on postoperative recurrence free survival (RFS) of colorectal cancer patients with peritoneal metastasis. Participants will: The patients were followed up according to the normal review procedure of the hospital and the NCCN guidelines until at least 24 months after surgery. The review content in
