Esophageal cancer may have multiple metastasis in the late stage, the most common one is stomach metastasis, which is the main reason for vomiting blood in the late stage, and the ulcer or tumor rupture in the stomach, which may be caused by downward invasion of the stomach by the esophageal cancer foci. In addition, liver metastasis may occur in the late stage, which may cause nausea, vomiting, distension and discomfort in the right upper abdomen, etc. Brain metastasis of esophageal cancer may cause increased intracranial pressure, dizziness, headache and other symptoms.

Generally speaking, when esophageal cancer reaches the advanced stage, there is no way to do surgery directly, but don't give up the treatment, you can do local radiotherapy and systemic chemotherapy to control the development of the disease, the purpose of local radiotherapy is to release the obstruction, so that the patients can eat something or control the development of the disease for the time being, and the systemic chemotherapy is to control the metastatic foci and try to reduce the load of the tumor, and to prolong the survival of the disease. The purpose of systemic chemotherapy is to control some metastatic foci, try to reduce the tumor load, and to prolong the survival, advanced patients can only try to symptomatic treatment, and then let the patients have no pain, try to prolong the survival of the treatment.
