This is a prospective, open-label, randomized controlled clinical trial, by monitoring the serum ctDNA mutational profile using NGS, aiming to elucidate the correlation between the postoperative ctDNA status and the assisted diagnosis, early intervention and prognosis for colorectal cancer peritoneal metastases.

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| ctDNA monitoring | Diagnostic Test | Patients who undergoing radical surgery for colorectal cancer for 6~12 months and with 2 consecutive positive ctDNA testing results within 1 month will be enrolled, and diagnostic laparoscopy will be performed immediately after enrollment. Patients with positive peritoneal metastasis (PCI score <20) will be treated with CRS+HIPEC. Tumor markers, endoscopic and imaging examinations, and ctDNA monitoring will be performed every 3 months in patients with negative peritoneal metastasis. Laparoscopy will be performed when imaging suggested peritoneal metastasis (oligometastases). Re-diagnostic laparoscopy will be performed 24 months after radical surgery when there is no radiographic evidence of recurrence or metastasis. Follow-up time will up to 36 months after colorectal cancer surgery. |
| Measure | Description | Time Frame |
|---|---|---|
| Peritoneal Metastasis Free Survival (PMFS) | The survival rate without peritoneal metastasis (oligometastatic) at 24 months after radical resection of colorectal cancer. | Through study completion, up to 3 years |
| Measure | Description | Time Frame |
|---|---|---|
| Detection Rate (DR) | DR of ctDNA monitoring for predicting peritoneal metastasis with abdominal exploration as the reference.

| Imageology | Diagnostic Test | Patients who undergoing radical surgery for colorectal cancer for 6~12 months and with 2 consecutive positive ctDNA testing results within 1 month will be enrolled. and there will be no need to conduct endoscopic exploration immediately after enrollment. Tumor markers, endoscopic and imaging examinations, and ctDNA monitoring will be performed every 3 months until imaging suggested peritoneal metastasis (oligometastases). Patients with positive peritoneal metastasis (PCI score <20) will be treated with CRS+HIPEC. Re-diagnostic laparoscopy will be performed 24 months after radical surgery when there is no radiographic evidence of recurrence or metastasis. Follow-up time will up to 36 months after colorectal cancer surgery. |

| Peritoneal Cancer Index (PCI) Score | This scale measures the extent of peritoneal cancer throughout the peritoneal cavity. The range of this scale is from 0 to 39. 0 = no disease within the peritoneal cavity 0-9 = minimal disease 10-29 = moderate disease 30-39 = extensive disease Lower values are considered a better outcome for the patient. Will be compared in both arms. | Interim analyses: After 69 patients have been enrolled, up to 1.5 years |
| Completeness of Cytoreduction (CC) Score | The degree to which the disease was able to be excised during the procedure. This scale ranges from CC0-CC3. CC0 = all disease has been cleared, with no visible peritoneal carcinomatosis after CRS CC1 = microscopic disease remains (Nodules persisting < 2.5 mm after CRS) CC2 = macroscopic disease remains (Nodules persisting between 2.5 mm and 2.5 cm) CC3 = Substantial Macroscopic disease remains (Nodules persisting > 2.5 cm) Lower values are considered a better outcome, with CC0/1 classed as favourable and CC2/3 indicating an incomplete clearance of disease. Will be compared in both arms. | Interim analyses: After 69 patients have been enrolled, up to 1.5 years |
