Esophageal cancer
Typical symptoms of esophageal cancer
The most typical symptom of esophageal cancer is progressive difficulty swallowing, and a progressive sensation of swallowing obstruction is the most typical symptom. It's actually quite simple; the esophagus is akin to a water pipe or a tubular cavity. Esophageal cancer is like having a tumor grow inside this cavity, similar to something blocking the pipe, which causes the flow of water to be impeded. However, not only water passes through this esophagus, but also food. Therefore, if there's something inside the cavity, both water and food cannot pass through, leading to this difficulty swallowing and discomfort while swallowing.
Esophageal cancer screening methods
The best and clearest method for screening esophageal cancer is still gastroscopy, which can also be referred to as esophagoscopy. Endoscopic examination is very significant for this type of luminal tumor. Of course, if some people truly cannot tolerate a gastroscopic exam, they might consider initially undergoing a barium meal for the esophagus or iodized oil radiography for diagnosis. Additionally, a chest CT scan can be performed to determine whether there is narrowing in the esophageal lumen or if there is metastasis in the surrounding lymph nodes, among other issues. However, the best and most important method is certainly the esophagoscopy, or taking a biopsy of the pathological tissue under gastroscopy, which is very important for the definitive diagnosis of esophageal cancer.
What are the symptoms of esophageal cancer recurrence?
The symptoms of recurrent esophageal cancer are similar to those at its initial onset, primarily characterized by difficulties in swallowing and eating obstructions. Some may also experience nausea, vomiting, and reflux symptoms of the digestive tract. Of course, when recurrence occurs, if there are metastases to other distant organs, then clinical manifestations corresponding to those metastatic locations will appear. For example, if esophageal cancer metastasizes to the lungs, it could lead to coughing, expectoration, shortness of breath, or chest pain, and even clinical symptoms related to coughing up blood. If there is liver metastasis from esophageal cancer, symptoms might include abdominal pain, fatigue, poor appetite, and even ascites among other clinical manifestations related to liver metastasis.
How long can one live with esophageal cancer?
The life expectancy of esophageal cancer patients depends on several factors such as the stage of the cancer at the time of diagnosis, the patient's sensitivity to treatments like radiotherapy and chemotherapy, the effectiveness of these treatments, the patient's general condition, and whether they have other underlying diseases. Patients who can undergo radical surgery, especially those diagnosed at an early stage, generally have a better prognosis. Patients who respond well to treatment can also expect a better outcome. Therefore, there is significant individual variation in prognosis.
Will esophageal cancer recur after resection?
After the removal of esophageal cancer, there is indeed a possibility of recurrence. This is because not only are there tumors on the esophagus, but some mediastinal lymph nodes around the esophagus may also have metastasized. It must be acknowledged that thoracic surgeons will definitely remove the tumor completely during surgery, but they can only remove the tumors that are visible to the naked eye. Many tumor cells that cannot be seen by the naked eye are impossible to remove. If the cancer is at a relatively advanced stage, many of these invisible tumor cells cannot be eliminated, just like air is invisible but still exists. Therefore, invisible does not mean there are no cancer cells. Thus, if there is no follow-up auxiliary treatment to kill the cancer cells, the cancer may very likely recur.
Symptoms of esophageal cancer spread
The most typical symptom of esophageal cancer, especially in its advanced stages, is difficulty swallowing. As esophageal cancer progresses, patients may further experience difficulty swallowing semi-liquid food, eventually leading to difficulty swallowing even water and saliva. Additionally, as the cancer develops, it might compress the trachea, resulting in symptoms like sticky sputum and difficulty in expectorating. Consequently, due to difficulties in eating, progressive severe weight loss and fatigue often occur. Furthermore, some patients may also experience chest or back pain, and in some cases, an esophageal-tracheal fistula might occur, leading to severe respiratory difficulties and intense choking. Moreover, after advanced esophageal cancer has spread, it may also cause jaundice, ascites, and can metastasize to other parts of the body, potentially resulting in various symptoms.
How to treat esophageal cancer metastasis?
The metastasis of esophageal cancer involves several aspects. The first aspect is the metastasis of lymph nodes, including those around the esophagus. If the number of metastatic lymph nodes is small and the tumor's location is suitable for surgical removal, then surgery can still be considered. The second issue involves cases where there is lymph node metastasis but with a higher number and wider spread, making surgical treatment unfeasible. In such cases, radical radiotherapy and chemotherapy can be considered to treat the esophageal cancer. Of course, there are also some new methods available now, such as immunotherapy, which can be considered along with others. Also, to improve symptoms of esophageal stricture, using an esophageal stent to control the difficulty of swallowing associated with esophageal cancer is also possible.
