The number of postoperative adjuvant chemotherapy for patients with stage III colon cancer is mostly about 6~8 times, so 6 times of chemotherapy is normal.
Colon cancer is a malignant tumor caused by bad dietary habits, gene mutation and other factors. Stage III patients are those whose tumor invades the submucosal layer of the intestinal wall or invades the intrinsic muscular layer; metastasis occurs in 1~3 regional lymph nodes; and there is no distant metastasis and so on.
Patients in this period often need adjuvant chemotherapy after surgical resection treatment to eliminate the residual lesions and reduce the recurrence rate. The number of postoperative adjuvant chemotherapy for colon cancer usually ranges from 6 to 8 times, which needs to be decided according to the specific conditions of patients. Commonly used chemotherapeutic drugs include oxaliplatin, fluorouracil, etc., which should be applied under the guidance of doctors.
