Esophageal Cancer Overview

By | May 7, 2012

Overview of esophageal cancer, esophageal cancer is one of the most common malignant tumors, according to China's national mid-70s retrospective survey of cancer death in men in cancer mortality, esophageal cancer ranks No. 2 (accounting for 24.55%), only secondary to gastric cancer; in the ranks No. 3 among women (accounting for 18.15%), second only to cancer, cervical cancer.
The geographical distribution of esophageal cancer is very broad, high concentration of North China's Shanxi region, Hebei Taihang Mountains, Shaanxi, Sichuan, Hubei Province, the Qinling Mountains, Fujian, Guangdong Province, the border region, and Shandong, Jiangsu, Gansu, Inner Mongolia, Xinjiang and other provinces, autonomous regions and parts of Linxian of Henan Province which is the world's highest rates of esophageal cancer in the world.
Esophageal distribution around the world, except for China, like Iran, the former Soviet Union and South Africa have a high incidence of esophageal cancer. The United States is the low incidence area of esophageal cancer, esophageal cancer accounts for only 1.5% of the body, accounting for 7% of gastrointestinal tumors.
Without special treatment of esophageal cancer patients, the average survival time after onset of symptoms is about 10 months. Surgical treatment of cases, about 20% survival rate after five years. Later, because a lot of census work conducted by cytology, imaging and double-contrast esophageal endoscopy and found a large number of early cases, and its five-year survival rate after surgical removal of more than 90%. This shows that to improve the efficacy of esophageal cancer, the key is early detection and early treatment.
CT scans can show the mediastinal esophagus and adjacent organs of the relationship between the extent of tumor outside the invasion, and lymph node metastasis, so the staging of esophageal cancer, it is estimated whether the surgical removal of tumor and help clinicians design treatment Dengjun plays a significant role. After treatment, followed up by CT cases, can clear whether the recurrence and metastasis of cancer.
Overview of esophageal cancer, esophageal X-ray barium meal is the main method of diagnosis of esophageal cancer, but early diagnosis of cancer there are still some difficulties, minor lesions sometimes can not be found; sometimes found abnormal signs, but not qualitative. By cytology, endoscopy and double contrast X ray imaging method of combining the esophagus to improve the diagnosis rate of early esophageal cancer.
MRI is the 80 new inspection method, which due to three-dimensional imaging, thus providing more information in the diagnosis of esophageal cancer, staging and treatment options are also useful. Currently few reports in this regard, be further explored.
