Precursor lesions of esophageal cancer in high-risk populations in Henan Province, China

Cancer. 1988 Aug 1;62(3):551-7. doi: 10.1002/1097-0142(19880801)62:3<551::aid-cncr2820620319>;2-y.


This report discusses precancerous changes in the esophageal mucosa from three points of view: the histopathologic features of the esophageal mucosa in persons known to be at high risk for esophageal carcinoma (EC); the histopathologic features of the esophageal mucosa of asymptomatic persons randomly selected from areas at high and low risk for EC; and a prospective follow-up of a randomly examined group to determine the impact of esophagitis and dysplasia upon subsequent development of EC. Esophagitis was commonly found at endoscopic examination, but there was no difference in frequency of esophagitis in the randomly selected subjects from high-risk and low-risk areas. Although one third of patients with dysplasia developed cancer over a follow-up period of 30 to 78 months, only 4% of those with esophagitis alone developed EC. The authors conclude that dysplasia, diagnosed by cytologic or histologic examination, is a precancerous state, and that esophagitis is a nonspecific pathologic condition of the esophagus, but moderate and severe types of chronic esophagitis might create an environment favorable for the development of esophageal carcinoma.
