|---|---|

Experimental: ctDNA dynamic monitoring + routine postoperative follow-up
ctDNA is detected before operation, before chemotherapy, and then every three months for 2 years, 10 times in total. At the same time, routine postoperative follow-up is given. To be pointed out, after the completion of the adjuvant chemotherapy, if the ctDNA test indicates positive, patients will immediately perform chest, abdominal and pelvic CT and other imaging tests to determine whether there is recurrence /metastasis. If it is not confirmed, repeat the imaging review every two months, and continue to perform ctDNA test every three months. If the following ctDNA test is negative for two consecutive times, the above imaging reexamination will return to the routine follow-up frequency. In addition, during the follow-up, the following situations may occur: the imaging examination has found recurrence/metastasis, but the ctDNA test is still negative. At this time, the patient will be informed and treated in time of the recurrence/metastasis. |
ctDNA is detected before operation, before chemotherapy, and then every three months for 2 years, 10 times in total.

|
Kein Eingriff: routine postoperative follow-up
Only routine postoperative follow-up is given as follows: Physical examination and CEA were performed every 3-6 months for the first 2 years, every 6 months within the third to fifth year, and then annually.
Chest/abdominal/pelvis computed tomography was performed annually for up to 5 years, and colonoscopy was performed for proper patients the first year after treatment and repeated in the third year if no advanced adenoma was found and then every 5 years.
