What complications can be induced by advanced esophageal cancer?
1, transferred to other organs
When esophageal cancer develops to the advanced stage, cancer cells can metastasize to important organs, such as lung, liver and brain, causing hepatic ascites, dyspnea, jaundice and coma. If it occurs in esophageal-tracheal fistula, metastasis of cancer cells to supraclavicular lymph nodes or other organs, cachexia, etc. Are symptoms of advanced esophageal cancer. If cancer cells invade the recurrent laryngeal nerve, it will lead to hoarseness and vocal cord paralysis. If cancer cells oppress or invade tracheobronchitis, it will cause irritating dry cough. If it invades the phrenic nerve, it will cause phrenic paralysis. If the vagus nerve is invaded, the heart rate will increase. If the brachial plexus nerve is invaded, it will cause numbness, pain and abnormal sensation in the arm. If it is compressed to the superior vena cava, it may lead to superior vena cava compression syndrome.
2. Cachexia
When esophageal cancer develops to the advanced stage, the symptoms of dysphagia will become more and more obvious. Due to long-term hunger, weight loss and negative nitrogen balance will occur, thus increasing the incidence and mortality of postoperative complications. When esophageal cancer appears cachexia or obvious dehydration, the main symptoms are emaciation, fatigue, loose and dry skin, mainly manifested as fatigue.
3, bleeding or hematemesis
Esophageal cancer is mostly accompanied by vomiting, especially when cancer cells invade large blood vessels, there will be vomiting blood and occasional massive bleeding.
4, esophageal cancer perforation
Perforation of esophageal cancer is the main complication of esophageal cancer. The advanced stage of esophageal cancer, especially ulcerative esophageal cancer, can be caused by local erosion and serious ulceration of cancer cells. The symptoms of different puncture sites and adjacent organs are also very different. If it penetrates the trachea, it can lead to esophagotracheal fistula, induce esophageal active vein, and even bleed to death. Pay attention to diet and recuperation in the late stage of esophageal cancer. If cachexia occurs, protein should be supplemented reasonably, which can be obtained from milk, eggs, lean meat and various vegetables. If there is complete obstruction, intravenous rehydration or gastrostomy should be taken to provide nutritious food to maintain life. Avoid eating cold food and food that has been left for too long, and supplement nutrition reasonably. Avoid smoking, drinking and drinking coffee. Face the disease correctly and eliminate bad emotions in time.
