In general, the recurrence rate of colon cancer 2 years after surgery is related to many factors, firstly, the stage of the disease, whether the treatment is standardized or not, the patient’s cooperation level and the patient’s mental condition. In general, the recurrence rate of stage 1 colon cancer 2 years after surgery is about 10% or less, which is very low. If stage 2 and 3 colon cancer is given regular radiotherapy after surgery, the recurrence rate is generally about 30%, and if there is poor cooperation and no active postoperative adjuvant therapy, the recurrence rate may reach about 60%. In case of stage 4 colon cancer, surgery is generally not recommended, but for patients with hepatic oligometastases, some of them can be considered for surgery, while others are just for palliative surgery and symptomatic treatment, and the recurrence rate after surgery is basically 100%, so the recurrence rate 2 years after surgery is basically 100%.
