What are the five chemotherapy methods for colon cancer?

In recent years, colon cancer has gradually risen again, and colon cancer screening has been elevated to a position that needs attention. Humans are afraid of death, but when it is really irreversible, they are powerless. There are countless people who have died from cancer, and colon cancer is one of the killers. People who are usually very careful and cautious will find symptoms in the early stage, but some people do not have any symptoms in the early stage, so it is best to have regular checkups. Clinically, it has been found that most patients with colon cancer have reached the middle and late stages when they show obvious symptoms. Here, we remind all friends who are related to colon cancer to pay attention.

Chemotherapy for colon cancer:

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.

Arterial infusion chemotherapy: Arterial infusion chemotherapy is one of the important means of comprehensive treatment of malignant tumors. Selective arterial infusion chemotherapy is an accurate targeted drug delivery, which allows high concentrations of anticancer drugs to be concentrated in the local tumor, effectively killing cancer cells, improving the therapeutic effect of surgery, significantly improving clinical symptoms, with mild adverse reactions, and a simple and safe method.

Portal vein infusion chemotherapy: 50% of patients with colon cancer will develop liver metastasis after treatment of the primary lesion. 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.

Intralymphatic chemotherapy: Lymphatic metastasis is considered to be 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 lymphatic tissue and improve the chemotherapy effect.

Intraperitoneal chemotherapy: When the tumor is squeezed and the lymphatic and blood vessels are cut during colon cancer surgery, cancer cells may fall into the abdominal cavity or form tiny lesions that are invisible to the naked eye. Intraperitoneal chemotherapy can directly increase the concentration of anticancer drugs in the abdominal cavity, increase the local cytotoxicity of the lesion, and reduce systemic adverse reactions.

Although chemotherapy for colon cancer has certain side effects, they are negligible compared to saving the lives of colon cancer patients.

The above is an introduction to "What are the five chemotherapy methods for colon cancer?" When the above symptoms appear, patients should go to a regular hospital for treatment. Early detection and early treatment can effectively cure colon cancer. People who are related to the pathogenic factors of colon cancer are advised to take preventive measures for colon cancer.
