It is a malignant disease of the esophagus (esophageal cancer) or esophageal cancer. Various subtypes is, preferably, there is a (approximately 50-80% of all cancers in the United States) and adenocarcinomas (about 90-95% of all cancers in the world) squamous cell carcinoma. Squamous cell carcinoma cells derived from the line of the upper esophagus. Adenocarcinoma arising from glandular cells located at the junction of the esophagus and stomach. This leads to symptoms usually, dysphagia (difficulty swallowing), such as pain, esophageal tumors diagnosed by biopsy. Tumor localization and small will be treated with curative intent surgery. Larger tumors can be operated possibility is to treat the palliative care is high, their growth can be delayed by a combination of chemotherapy, radiation therapy or still. In some cases, radiation therapy and chemotherapy, can be large tumor of these triggers. Extent of the disease, and the prognosis depends on the medical problems of the other, but usually relatively low.
Usually, esophageal cancer arising from or mucosal surface epithelium of the esophagus cancer. Is similar to squamous cell carcinoma, which are classified into one of two classes, type of cancer of the head and neck, and the consumption of alcohol and tobacco, in many cases, esophageal cancer, most in the history of the esophagus and gastroesophageal reflux adenocarcinoma associated with Barrett. A general rule of thumb is one of adenocarcinoma is one of the lower third and squamous cell carcinoma is cancer of two thirds of the upper part. Rare histological type of cancer, were non-epithelial tumor leiomyosarcoma, malignant melanoma, rhabdomyosarcoma, such as lymphoma and such embodiment, the squamous cell carcinoma that different.
Swallowing pain is the most common symptom (painful swallowing) of esophageal cancer and dysphagia (difficulty swallowing). Dysphagia is the first symptom in most patients. Pain on swallowing may be present. Typically, soft food and liquid is allowed while cause much more difficult (such as bread and meat, for example) substance bulky or hard. It is characterized by significant weight loss, decreased appetite, malnutrition, as a result of active cancer. Pain in the upper abdomen and the back of the breastbone, burning often, heartburn, can be worsened by death to present themselves almost every day is difficult, swallowing any form of food as this nature. Tumor affects the recurrent laryngeal nerve, as a result, another sign may cough sounding hoarse husky or raspy abnormally.
Presence of a tumor can be used to distort lead nausea of an increased risk of pneumonia food, cough, vomiting, and reflux, the normal peristalsis (swallowing sponsored by the reflection). Tumor surface will be able to cause (vomiting of blood) vomiting blood, the fragile and bleed. The degree of local structures, occlusion of the upper airway such occur and lead to problems such as the superior vena cava syndrome, in advanced stages of the disease. The stoma may occur between increasing the risk of pneumonia, and the trachea and the esophagus, the condition is applied normally, coughing, by filling and heating.
People, half of the inside of the esophagus, while called lumen is clogged, most people with a diagnosis of cancer, with the later stages of the disease to have an important symptom in general , when the tumor is quite large. If the disease has spread to other places, may lead to symptoms associated with this: This may cause ascites transition and jaundice in lung metastasis liver, can cause shortness of breath, pleural effusion .
Obstructive tumors are likely to be barium or barium swallow, but the diagnosis will adopt a flexible tube to best esophagus below, are made (EGD, endoscopy) in the esophagus stomach it contains at a examine the wall. I was examined histologically for signs of malignancy taken biopsy of suspicious lesions. Usually, Additional testing is performed to assess the stage of the tumor. Computed tomography of the pelvis thorax, and abdomen (CT), it is possible to evaluate the cancer to see if it spread to (lymph nodes and liver in particular) distant organs or adjacent tissue.
(For example involving positron emission tomography greater than 1cm normal or lymph nodes were enlarged by weight, which is considered is used to evaluate the extent of disease, to be more accurate than CT alone sensitivity of CT it is limited by its ability to detect the organ). Esophageal endoscopic ultrasound, you can level staging, tumor invasion, and provide information about the spread of the possibility of regional lymph nodes. In general, the location of the tumor is measured by the distance from the tooth. Normally, the esophagus (25 cm or 10 inches) is divided into three parts for purposes of position determination. Adenocarcinoma tends to distal and proximal to squamous cell carcinoma, it may be true and vice versa.
