Outcome Measures

Primary Outcomes (2)

  • ctDNA status

    Detect postoperative tissue ctDNA status

    Two weeks

  • ctDNA dynamic detection

    ctDNA dynamic monitoring during postoperative adjuvant chemotherapy

    6 months

Secondary Outcomes (2)

Study Arms (2)

ctDNA positive patients

EXPERIMENTAL

Postoperative ctDNA-positive patients will receive chemotherapy for 6 months.The ctDNA dynamic detection and imaging examination will be completed every 3 months, and tumor markers will be detected in each chemotherapy cycle.

Procedure: Chemotherapy time

ctDNA negative patients

ACTIVE COMPARATOR

Postoperative ctDNA-negative patients will receive chemotherapy for 3 months. The ctDNA dynamic detection and imaging examination will be completed every 3 months, and tumor markers will be detected in each chemotherapy cycle.

Procedure: Chemotherapy time

Interventions

6 months of chemotherapy

ctDNA positive patients

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • \. Patients with colorectal cancer diagnosed pathologically as stage Ⅱ and stage Ⅲ.
  • \. The patient underwent radical surgical treatment.
  • \. The patient has the results of genetic genetic testing for gastrointestinal tumors, including the genetic mutation status of MMR genes and related genes (MLH1, MSH2, MSH6, PMS2, MLH3, EPCAM).
  • \. The patient understands and is willing to sign a written informed consent document.
  • \. During the treatment process, the patient can cooperate to provide samples of each node.
  • \. The patient can provide corresponding clinical materials, including but not limited to case diagnosis, imaging evaluation, and serum protein marker test results.

You may not qualify if:

  • \. The patient cannot provide a complete and qualified specimen.
  • \. The patient has other primary malignant tumors or serious medical illnesses.
  • \. The patient cannot cooperate with the follow-up.
  • \. Conditions that other researchers deemed inappropriate for continuing to participate in the study.
