Cardiac Carcinoma

Cardiac Carcinoma is one type of gastric cancer, called gastric cardia cancer, also known as Carcinoma of esophagus and cardia. Cardia is a special part of the anatomy, the stomach is the esophagus leading to the opening of histological squamous cell esophageal and gastric columnar epithelium in this clear-cut boundaries, and its distance of 0.5 ~ 4cm annular region around the cardia with irregular distribution glands, tubular or branch shape. Most of this area width 2cm. Early cardiac centers in the esophageal gastric junction line 1.75cm range, consistent with the distribution of cardiac gland region, it is clearly the origin of these cancers in the glandular cardia, all histological types are adenocarcinoma. Based on these anatomical and organizational learning took place, the correct definition of the Cardiac Carcinoma is occurred in the gastric cardia and esophagogastric junction line is about 2cm within the scope of adenocarcinoma. It is a special type of gastric cancer should be and to distinguish between lower esophageal cancer. But it and other parts of the stomach are different organizations with their own anatomy and clinical performance characteristics, unique diagnostic and treatment methods as well as the poor results of surgical treatment.

Cardiac Carcinoma origin from the neck stem cells of cardiac gland, because of how the direction of differentiation potential, can form a cardia adenocarcinoma glandular characteristics. The majority of light microscopy, electron microscopy can found that Cardiac Carcinoma is mixed, atypical hyperplasia is a precancerous lesion of gastric cardia, which is also related to incidence of cardiac-related ulcers, polyps, atrophic gastritis shared key pathological process. When they do not occur when changes in atypical hyperplasia may be cancerous, in which the majority of colon-type metaplasia with the nature of atypical hyperplasia.
