Cancer is a systemic disease. In the late stage, it is generally impossible to perform radical surgery. However, in some cases, palliative surgery can also be considered to reduce the burden of tumor. In addition, for advanced cancer, systemic adjuvant chemotherapy and local radiotherapy can be considered to control the disease development and prolong the survival period. In some cases, when the cancer spreads and metastasizes extensively in the late stage and the patient's physical condition is poor, including radiotherapy and chemotherapy, it can also be considered to use targeted drug therapy. For example, advanced gastric cancer can neither be operated nor treated with radiotherapy or chemotherapy, and apatinib can be used for oral targeted treatment. Some patients also have effects, which can extend the survival period. In addition, symptomatic treatment is also needed, including cancer patients. If they have pain, powerful analgesics can be used; If you can't eat, and the nutrition is poor, you can use nutritional support and other symptomatic treatment.
