Esophageal cancer screening

By | May 7, 2012

Esophageal cancer survey, carried out in areas of high incidence of esophageal cancer esophageal cancer census is very important to achieve early detection through screening, early diagnosis and early treatment, so that it may reduce the mortality rate of esophageal cancer. Pop cytology is an effective method of detecting early esophageal cancer, so the general advance esophageal cytology screening. High incidence of cancer in the region, all 30 residents over the age of cytology screening, the discovery of cancer cases, and patients with symptoms and negative cytology, further X-ray examination. Cytology and X-ray co-ordination, making location and diagnosis of carcinoma and suspicious for early esophageal cancer should be further endoscopic examination, in order to get a clear histopathological diagnosis.
1984 Chinese Academy of Medical Sciences Cancer Institute's medical staff in Linxian, Henan Province, the four communes of the 30 residents of 17,380 people over the age of the census, the first pull-net esophageal cytology, cytology found 337 cases of squamous cell carcinoma, adenocarcinoma 58 cases, X ray checked 311 cases, were found to have cancer by cytology. X-ray diagnosis in 46 patients with advanced esophageal cancer, 122 cases of early esophageal cancer, 21 cases of suspected early cancer, x ray no lesions, 34 patients in advanced cardiac in 18 cases, 2 cases of early gastric cardia. Esophageal cancer screening, with the fibers throughout the esophagus and biopsy pathology analysis: X-ray diagnosis of early esophageal cancer in 122 patients, esophagoscopy and pathology of early cancer. X-highly suspicious in 21 cases of early cancer, 13 patients with biopsy for cancer, 8 cases of esophageal dysplasia. X-negative 34 cases, 25 patients with biopsy for cancer, 9 cases of esophageal dysplasia. From the above case analysis, x-ray diagnosis of early esophageal cancer was 81.4% accuracy, sensitivity 84.3%, 4.4% false positive and false negative of 14.1%. Seen in this light, although the final diagnosis requires esophagoscopy and pathology, but the X-ray examination in early diagnosis of esophageal cancer is still more important role.
Esophageal cancer survey in 1970 to 1972 in Linxian, Henan Province, La web cytology screening 11,564 people and found 135 cases of esophageal and gastric cardia of each, of which 96 cases of early cancer, early detection was 70.6%. In areas of high incidence of cancer patients waiting to check the commune hospitals, found detect early cancer does not exceed the total 5% of esophageal and gastric cardia, let alone in the city hospital. Survey work described above the importance of prevention and treatment of esophageal cancer.
