Shandong, China (Reuters) cardia occurred in the gastric cardia, which is the line of esophagogastric junction adenocarcinoma within the range of about 2cm. It is a special type of gastric cancer, also known as gastric cardia, and esophageal cancer should be distinguished. Like other tumors, the cause is unknown, may be related to dietary factors, environmental factors, genetic factors and Helicobacter pylori infection. Other problems such as chronic atrophic gastritis, gastric ulcer, gastric polyps, gastric epithelial cell metaplasia and gastric epithelial dysplasia and other precancerous changes. Pok past in gastric cancer tissue, gastric ulcer, gastric polyps and chronic atrophic gastritis is considered to be both precancerous gastric lesions. In recent years, studies have found these kinds of situations occur Ji little chance of cancer. Especially in the cardia three cases less than other parts of the stomach occurs. So obviously a relationship with the cardiac tissue is not.
Cardiac symptoms are generally based on the different course of the disease vary:
First, the early symptoms of cardiac There are two cases: 1, if the lower esophagus occur, so that the already very narrow cardia will be more narrow, therefore, prone to very similar symptoms and esophageal cancer; 2 If the body occurs in the stomach, or stomach side of the head, then when there was virtually no early symptoms. Abnormal when the initial sense of food or through pain, mild chest pain.
Above symptoms, will feel in the swallowing and swallowing hard food, I felt like falling into the stomach directly, in particular, drinking hot or cold liquid is more sensitive, which was originally one of the most obvious sense. If the cancer, these symptoms occur, there has been. Symptoms similar to non-cancer patients, these symptoms will be flickering, no regular, the severity of symptoms is not the same. Deterioration of symptoms, swallowing disorders, abdominal heaviness, stomach pain, nausea, vomiting, progressive weight loss.
Second, the cardiac symptoms between the mid and late symptoms among the early symptoms, showed a progressive development. Currently the view is more recognized cardiac origin cardiac stem cells in the neck glands, due to multiple differentiation potential, can be formed with the characteristics of cardia adenocarcinoma, or glandular epithelium. Cancer Hospital, experts say, the majority of cardiac light microscopy, electron microscopy and histochemical findings are mixed, the strong support of the view, atypical hyperplasia is a precancerous lesion of gastric cardia, and it is also in the incidence of gastric cardia the ulcers, polyps, atrophic gastritis shared key pathological process. When they occur when dysplastic changes may be cancerous, in which the majority of colonic metaplasia with dysplasia nature.
Third, the late cardiac symptoms common symptoms are: extreme cachexia, anemia, edema, systemic failure scorpion, liver, lung, brain and other vital organs and peritoneal metastasis, pelvic metastasis, causing pots of blood, ascites Su bloody ascites, hepatic failure, coma, gastrointestinal obstruction.
Cancer experts, possible late cardiac intervention. Intervention is characterized by invasive, simple, safe, effective, less complications and hospital stay was significantly shorter. Need medical treatment for diseases, interventional treatment has the advantage of: drugs can act directly on the lesion, the lesion can not only greatly improve the drug concentration, can significantly reduce drug use, reduce drug side effects. Targeted therapy, the concentration of the body by 50 to 100 times the concentration, but the total amount of drugs less. High concentrations of these drugs injected directly into the tumor continuously for blood vessels, 10 minutes will be able to kill cancer cells.
