The emergence of secondary malignant tumor after colon cancer surgery indicates that tumor metastasis has already appeared, which is mostly in the advanced stage of the tumor, and the possibility of cure is small, and the main purpose of treatment is to prolong the patient’s survival time as much as possible and improve the quality of survival.
When distant organ metastasis occurs after colon cancer surgery and secondary malignant tumor is found, comprehensive treatment is the mainstay, including chemotherapy, radiotherapy, targeted therapy and immunotherapy.
Commonly used chemotherapy drugs include oxaliplatin, 5-fluorouracil, capecitabine, etc. Commonly used targeted therapy drugs include cetuximab, bevacizumab, etc. Immunotherapy mainly uses immune checkpoint inhibitors (PD-1 and PD-L1), such as pembrolizumab. The above drugs should be taken according to the doctor’s prescription, and should not be taken without authorization.
For patients with good basic conditions and meeting the indications for surgery, palliative surgery can also be adopted, such as resection of liver metastases, interventional embolization chemotherapy, radiofrequency ablation therapy, etc., which can effectively reduce the tumor load, and the combination of internal medicine and radiotherapy can prolong the patients’ survival period to a certain extent.
Patients with metastasis after colon cancer surgery are recommended to go to the hospital as soon as possible, and ask professional doctors to evaluate their conditions and give them appropriate treatments, so as to inhibit the growth of tumor as much as possible, improve the quality of patients’ survival and prolong their survival period.
