Colon cancer chemotherapy refers to the use of chemical drugs in order to kill tumor cells and treat colon cancer, which can usually be used as postoperative adjuvant therapy.
Clinical research shows that some colon cancer patients may still have tiny metastatic foci remaining after radical surgery, so in order to reduce the risk of postoperative recurrence and prolong patients’ survival, postoperative adjuvant chemotherapy is recommended.
At present, the commonly used chemotherapeutic drugs are 5-fluorouracil, oxaliplatin, capecitabine and so on. Intravenous administration, intestinal lumen administration, portal vein administration or abdominal perfusion administration can be considered according to the patient’s condition.
Usually chemotherapy is not needed after surgery for stage I colon cancer, and it is recommended for stage III and IV colon cancer. Chemotherapy can also be selectively applied to patients with high-risk stage II colon cancer. Specific medication should follow the doctor’s prescription.
