Several common chemotherapy methods for colon cancer

Chemoradiotherapy is a commonly used treatment method for colon cancer in clinical practice. Different treatment methods should be adopted according to the different conditions of colon cancer patients. What are the common treatment methods for this type of colon cancer ? The following will tell you about the common treatment methods for this type of colon cancer.

Common treatments for this type of colon cancer include:

1. Portal vein infusion chemotherapy: 50% of colon cancer patients will develop liver metastasis after the primary lesion is treated. To prevent the occurrence of postoperative liver metastasis, postoperative portal vein infusion of drugs has a good effect. However, its clinical value needs to be further confirmed. This is a common treatment method for colon cancer.

2. Intralymphatic chemotherapy: Lymphatic metastasis is considered one of the most important ways for colon cancer to metastasize. Traditional intravenous chemotherapy cannot solve the problem of lymphatic metastasis due to the low drug concentration in the lymphatic system. Only intralymphatic chemotherapy can achieve effective drug concentration in the lymphatic tissue and improve the chemotherapy effect.

3. Intraperitoneal chemotherapy: When the tumor is squeezed and the lymphatic and blood vessels are cut during colon cancer surgery, it is possible that cancer cells will fall into the abdominal cavity or that cancer cells that have already spread on the peritoneum will form tiny lesions that are invisible to the naked eye. This treatment method for colon cancer can directly increase the concentration of anticancer drugs in the abdominal cavity, increase the cytotoxic effect of the local lesion, and reduce systemic adverse reactions.

4. Intraluminal chemotherapy: During laparotomy, the intestinal tract is ligated about 8-10 cm away from both ends of the tumor, and then drugs and saline are injected into the intestinal cavity where the tumor is located. Conventional surgery is then performed to increase the 3-, 5- and 8-year survival rates.

5. Arterial infusion chemotherapy: This is also a common treatment for colon cancer. Selective arterial infusion chemotherapy is an accurate targeted drug delivery that concentrates high concentrations of anticancer drugs in the local tumor, effectively killing cancer cells and improving the therapeutic effect of surgery. It significantly improves clinical symptoms, has mild adverse reactions, and is simple and safe.

The above is an introduction to the common treatment methods for colon cancer. I hope it will be helpful to everyone. Once you have colon cancer, you must face the treatment positively. A positive attitude is very beneficial to the treatment of colon cancer.
