Abstract:
Objective To investigate the distribution of precancerous conditions and lesions of high-risk population in the high-incidence area of esophageal cancer in Ci County, Hebei Province.
Methods Esophageal cancer was detected early in 40 to 69 year old patients in Ci Xian through endoscopic screening data and endoscopic screening using iodine staining and indicative biopsy. The patients were classified according to gender, age group, statistical esophageal precancerous condition, and lesion detection rate.
Results The analysis included 11 423 cases by screening queue, and the esophageal biopsy rate was 66.90%. The detection rates of squamous epithelium with mild, moderate, and severe dysplasia were 11.84%, 2.66%, and 1.04%, respectively. DCIS detection rate was 0.40% in patients with squamous cell carcinoma. The detection rate of the patients had been infiltrated by the squamous cell carcinoma was 0.04%.The rate of the squamous cell carcinoma within the mucosa was 0.37%.The rate of the infiltration squamous cell carcinoma was 0.17%. The detection rate of the hyperplasia above average severe dysplasia and cancer was 2.01%.
Conclusion High incidence of esophageal precancerous lesions was found in the Ci County aged 40 to 69. A large number of asymptomatic patients with cancer were detected. Age and sex are closely related to detection rate.
