Study Design: Two-year cross-sectional study.

Setting: Otolaryngology training programs.

Effectiveness of Intensive Endoscopic Screening for Esophageal Cancer in China: A Community-Based Study.

Evidence is required to evaluate the effectiveness of population-level endoscopic screening for esophageal cancer (EC). In this study, 5,632 permanent residents aged 25-65 years from 6 villages in Hua County, Henan Province, China, were defined as the screening cohort and were offered intensive endoscopic screening. Residents of all 914 remaining villages in Hua County were included as the control cohort, and age-sex standardization was used to calculate the expected numbers of EC and upper gastrointestinal (GI) tract cancer cases and deaths in the screening cohort.

Anti-HPV-E7 seropositivity and risk of esophageal squamous cell carcinoma in a high-risk population in China.

Results of previous serologic studies on the association of human papillomavirus (HPV) with esophageal squamous cell carcinoma (ESCC) have been inconsistent. From 2007 to 2010, the authors collected blood samples and relevant demographic data from 1435 patients with ESCC and 2071 age- and sex-matched normal controls from Anyang, China. HPV-16, 18 and 57 E7 antibodies were evaluated with the glutathione-S-transferase capture ELISA.

Human papillomavirus infection and esophageal squamous cell carcinoma: a case-control study.

Background: The risk factors for esophageal squamous cell carcinoma (ESCC) in the high-incidence areas of China remain unclear.

Methods: A total of 300 patients with ESCC and 900 controls matched for age and sex were enrolled in Anyang (China), a high-risk area for ESCC in China. In tumor tissue of the cases and in esophageal biopsies of controls, the presence of human papillomavirus (HPV) DNA was assessed by an SPF1/GP6(+)-mediated PCR followed by sequencing.

The Anyang Esophageal Cancer Cohort Study: study design, implementation of fieldwork, and use of computer-aided survey system.

Background: Human papillomavirus (HPV) has been observed repeatedly in esophageal squamous cell carcinoma (ESCC) tissues. However, the causal relationship between HPV infection and the onset of ESCC remains unknown. A large cohort study focusing on this topic is being carried out in rural Anyang, China.
