Rectal cancer its tumor cells may have this kind of metastasis to the liver through blood vessels and blood flow, then we call it liver metastasis of rectal cancer, then it needs to be distinguished from the primary tumor of the liver, the primary tumor of the liver is the liver’s own cells have undergone malignant transformation and become tumor, and this kind of foreign malignant tumor is different, then this is called the primary tumor of the liver and metastatic tumor, metastatic cancer, then Metastatic cancer of the liver. If liver metastasis occurs in rectal cancer, it depends on the number of metastatic lesions and the location of the metastasis, which may cause jaundice, discomfort and pain in the liver area, and abnormal liver function. Nowadays, it is believed that liver metastasis of rectal cancer is not an advanced stage of the disease, so through active surgery-based treatment, good results can be achieved. The treatment model of rectal cancer liver metastasis is now a multidisciplinary discussion model and a multidisciplinary consultation model. Integrated Chinese and Western medicine treatment is the best treatment for rectal cancer liver metastases Integrated Chinese and Western medicine treatment can improve the treatment effect, significantly improve the patient’s prognosis and prolong the survival period. Resection of liver metastases from rectal cancer is safe and is currently the treatment method that has the potential to improve the long-term survival rate of patients who have metastasized. However, only about 10-20% of patients are suitable for surgical resection, and 70% of them recur after surgery. Surgical treatment includes local resection of the liver or lobectomy of the liver, and the 5-year absolute survival rate after surgical resection of liver metastases from rectal cancer can reach 23%-40%. Systemic chemotherapy for rectal cancer liver metastasis is a kind of palliative chemotherapy, which aims to control tumor growth, prolong patients’ survival as much as possible and relieve liver metastasis symptoms. However, chemotherapy will also cause certain damage to normal tissue cells and has great toxic side effects, which is one of the bottlenecks of its treatment. The effect of surgery and chemotherapy in treating rectal cancer liver metastasis is not very ideal. If combined with TCM treatment after surgery, it can remove residual tumor cells, prevent recurrence and metastasis, enhance patients’ survival quality and prolong life. The combination of TCM treatment with chemotherapy can effectively remove the toxic side effects produced by chemotherapy and improve patients’ immune ability and tolerance to chemotherapy drugs. Combination therapy is the best choice for patients with rectal cancer liver metastasis. Liver metastasis of rectal cancer means serious threat to life, and we hope patients will receive treatment as soon as possible in order to effectively prolong their survival.
