    ABSTRACT: Anyang in Henan Province of China is a hyperendemic area of esophageal cancer. The infection of human papillomavirus (HPV) is thought as an important pathogenesis of esophageal cancer in Anyang. This study was to detect infection rate and level of HPV-16 in esophageal squamous cell carcinoma (ESCC) patients from 3 different Chinese areas, and investigate its relationship with the pathogenesis of ESCC. Infection status of HPV-16 in 119 ESCC specimens (43 collected from Anyang, 43 from Beijing, and the rest 33 from Mongolia nationality of Inner Mongolia) was detected by in situ hybridization (ISH) technique with digoxin-labeled HPV-16 E6 probe. HPV16 infection rates were 81.4%, 69.8%, and 63.6% in the specimens from Anyang, Beijing, and Inner Mongolia, respectively. Infection level of HPV-16 was significantly higher in Anyang group than in Beijing group (H=3.91, P<0.05) and Inner Mongolia group(H=4.22,P<0.05). There was no significant difference between the latter 2 groups. Furthermore, the proportion of strong expression of HPV16 (++ and +++) was significantly higher in Anyang group than in the other 2 groups(H=3.95, P<0.05). HPV-16 infection rate is high in the esophageal specimens from the 3 different areas. Infection status of HPV16 is serious in Anyang.

    ABSTRACT: To investigate the association between the single nucleotide polymorphisms (SNPs) of interferon regulatory factor 3 (IRF-3) gene and the susceptibility of esophageal cancer in Anyang area, Henan Province. The genomic DNAs of 152 esophageal cancer patients and 191 health controls were extracted from the peripheral blood leukocytes. Three fragments covering codons 96, 194, 377, and 427 of the IRF-3 gene were amplified by polymerase chain reaction (PCR). The SNPs were revealed by DNA sequencing and the genotype of every sample was determined accordingly. The frequency distribution of the SNPs was analyzed by chi(2) test. There were no IRF-3 gene SNPs at codons 96, 194, or 377 in Anyang participants. There was significant difference in the SNPs at codon 427 between the healthy controls and esophageal cancer patients in Anyang area OR=2.38 (95%CI=1.15-4.95,P<0.05). The SNPs at codon 427 of the IRF-3 gene may relate to the susceptibility of esophageal cancer. The risk of esophageal cancer in participants with C allele is 2.38-fold compared to those with G allele.
