Lymph node metastasis caused by cardia cancer is usually in the paracentral cardia, lower parietal esophagus and lesser curvature of the stomach. However, the most common clinical manifestation being palpated is lymph node metastasis from cardia cancer to left supraclavicular lymph node. The location of lymph node metastasis caused by cardia cancer is mainly where the lymph at cardia flows to recently, firstly, the lymph nodes adjacent to cardia are invaded, secondly, the paraesophageal lymph nodes close to cardia, and thirdly, the lymph nodes at the lesser curvature of stomach close to cardia. Distally, it can invade upward along the esophageal wall to the mediastinum and supraclavicular lymph nodes, or downward from the lesser curvature of the stomach to the parietal abdominal artery. Cardia cancer should go to regular hospitals for consultation in time, and the doctor will decide whether there is lymph node metastasis and its metastatic location according to the specific situation.
