The survival time of patients with esophageal cancer, also known as esophageal cancer, is affected by many factors, such as disease stage, metastasis and treatment. Esophageal cancer is a malignant tumor located in the epithelial tissue of the esophagus and can be classified into early, intermediate and late stages according to the tumor diameter, infiltration and metastasis. The survival time of patients with this disease is determined according to the disease stage, metastasis and treatment. Early stage tumors only invade the esophagus without peripheral infiltration or metastasis, and after surgical treatment, the 5-year survival rate is about 40%, and the survival time of some patients can reach 10 years. The survival time of patients with mid-stage tumor with lymphatic metastasis is determined by the number of lymphatic metastases after treatment, and the more the number of metastases, the shorter the survival time. The more the number of metastases, the shorter the survival time. In advanced stage, the tumor mostly infiltrates into the periphery of esophagus or has distant metastasis, and the survival time of patients is even shorter. Therefore, it is recommended to have regular medical checkups to facilitate early detection and early treatment.
