How to treat colon cancer after regular follow-up surgery

After radical resection, patients with colon cancer need to follow the doctor's advice and visit the hospital for regular follow-up visits. If recurrence or metastasis occurs, auxiliary treatments such as chemotherapy and radiotherapy should be taken in a timely manner.

1. General situation: For early stage I colon cancer without lymph node and distant organ invasion, the cure can be achieved after active and standardized surgical operation, and the 5-year survival rate can reach more than 90%. Therefore, such people do not need special treatment, and only need to go to a regular medical institution for imaging examination every 3-6 months;

2. Pathological staging: If it is mid-to-late stage colon cancer, that is, the tumor has invaded the serosal layer or surrounding tissues and has regional lymph node metastasis, it is usually impossible to completely remove the lesions by surgery alone. At this time, it is recommended to combine other methods for comprehensive treatment. Among them, chemotherapy is the main method, including single-drug therapy and combination therapy. Commonly used chemotherapy regimens include fluorouracil calcium folinate (Quick and Ling), capecitabine oxaliplatin, irinotecan cisplatin, etc. In addition, radiation irradiation can be used to control the progression of the disease, but this method is only suitable for patients in the local advanced stage or with multiple metastases to the liver, lungs, and brain;.

3. Targeted drug therapy: Currently, bevacizumab injection is widely used in clinical practice. It mainly acts on vascular endothelial growth factor receptors, inhibits the formation of new blood vessels, and thus blocks nutritional support. Clinical studies have shown that it has a good effect on colorectal cancer and can prolong the patient's overall survival time. In addition, there is regorafenib tablets, which is an oral small molecule multi-kinase inhibitor, mainly used for patients with metastatic colorectal cancer who have received systemic treatment in the past, especially those with BRAFV600 mutation.

Patients with colon cancer should receive targeted treatment based on their own conditions, while maintaining a good attitude and actively cooperating with doctors to complete follow-up treatment, which will help improve their quality of life and prolong their survival.
