Pathophysiology Of Esophageal Cancer

Esophageal cancer is a tumor that begins to grow in the lining of the esophagus, and then can grow through the bulwark of the esophagus.

If a malignant tumor grows here, its called adenocarcinoma which is what my pt has. Studies have shown a league between frequency of reflux symptoms and risk of adenocarcinoma. The constant demigod reflux will irritate the lining of the esophagus, and complications can occur, much(prenominal) as Barretts esophagus (a condition that occurs because of continued reflux of winding from the stomach into the lower esophagus.) The reflux eventually changes the cells at the transshipment center of the esophagus. Esophageal tumors begin as benign growths and grow rapidly because there is no serosal la yer to stop growth. Because of the vast lymphatic network of the esophagus, esophageal cancers spread fast, both locally to regional lymph nodes and distantly to the lungs and liver.

Complications include pulmonary problems that result from fistulae and aspiration, including pneumonia and pulmonary abscess; onset of the tumor into major vessels, causing a intensityive bleed; restriction and compression of the other structures in the head and make come on; weight loss and nutritional deficiencies due to bar swallowing; solid food impaction can result when there is afflictive stenosis, requiring endoscopi c intervention for disimpaction; regurgitati! on of food or vocal music secretions may also occur; or the tumor down may cause compression and obstruction of the tracheobronchial tree, leading to dyspnea( trouble breathing), inveterate cough, and at times post obstructive pneumonia.
