ABSTRACT
Objective To study the prevalence of esophageal cancer and various lesions of esophagus in high risk areas through a screening program for early diagnosis and treatment.Methods Random cluster sampling method was used to select some portions of a natural village as screening object in the high risk areas of esophageal cancer,from 2006 to 2011.Endoscope iodine staining and index biopsy screening methods were used on people with high risk and followed by pathological exams for confirmation.Results The detection rates regarding mild esophageal hyperplasia,moderate and severe esophageal hyperplasia were 5.33% (803/15 065),1.28%( 193/15 065 ),0.68%( 102/15 065 ) respectively while the detection rates on carcinoma in situ,intramucosal carcinoma and invasive cancer were 0.15%(22/15 065),0.06%(9/15 065),0.29%(43/15 065)respectively.The detection rate in male esophageal hyperplasia was higher than in female.People younger than 65 years old,the detection rates on mild,moderate or severe esophageal hyperplasia and invasive cancer showed an increase with age,with the 60- year-olds group reaching the highest.The detection rates on the above said diseases were 7.72%( 198/2565 ),2.07%(53/2565),1.29%( 33/2565 ),0.51% ( 13/2565 ) respectively.The detection rates on mild,moderate or severe esophageal hyperplasia varied in different years and with statistically significant differences (P<0.001) but did not show any obvious trend of changing.Geographical distribution of mild esophageal hyperplasia,moderate esophageal hyperplasia,severe esophageal hyperplasia also significantly varied in different villages (P<0.001).The highest detection rate in the mountainous villages was seen the highest while the detection rate of village from hilly areas was the lowest.Conclusion There were considerable numbers of patients with precancerous lesions in the general population from the high risk areas.The detection rate of esophageal cancer in the mountain residents was higher than the rate in the hilly areas.Men and the elderly were the key populations calling for esophageal cancer prevention programs to be carried out.
