Epidemiological study of precursor lesions of oesophageal cancer among young persons in Huixian, China.
A total of 538 subjects (354 males, 184 females) were investigated in a high-risk area for oesophageal cancer in China to provide large-scale data on the prevalence of chronic oesophagitis among persons below 25 years of age. The survey included an oesophagoscopy with guided biopsies and cytology, a physical examination, an interview and collection of a 10-ml blood sample and overnight urine. Histologically confirmed oesophagitis was found in 43.5% of male and 35.6% of female subjects. Mild and moderate oesophagitis was associated positively with consumption of burning hot beverages, family history of oesophageal cancer, frequent consumption of cottonseed oil, cigarette smoking, a clinical diagnosis of oral leukoplakia and seborrhoeic dermatitis; negative associations were seen with frequent consumption of fresh fruit, meat and eggs. A significantly higher level of urinary nitrate was found in the diseased group, but no difference was seen with regard to any of the N-nitrosamino acids measured.
