Esophageal cancer is one of the common malignant tumors, especially in China and the annual incidence of esophageal squamous cell carcinoma is 260,000 with the motility of 210,000. In western countries, the incidence of esophageal adenocarcinoma (esophageal - gastric junction carcinoma) now dramatically increased than in the past. The pathological types of highest incidences are changing from esophageal squamous cell carcinoma (Esophageal Squamous Cell Carcinoma, ESCC) to esophageal adenocarcinoma (Esophageal adenocarcinoma, EAC) whose incidence is about 60-70%. But in Asia, esophageal squamous cell carcinoma is still the dominant pathological type, accounting for more than 95%. The prognosis of esophageal cancer is very poor. About 50% of patients have advanced disease at diagnosis and the natural course is only 6-8 months with a 5-year survival rate of 5-7%. In addition, though some patients received surgical treatment, disease will recurrent and metastasis in nearly 90% of the patients. For those patients in early stage (T1), there are still nearly 50% of patients relapse within 5 years. Therefore, in recent years, doctors and researchers in different countries are continued to seek effective treatment to improve the quality of life of patients with esophageal cancer and prolong survival.
