Core Tip
Core tip: China is considered to have a high incidence of esophageal cancer. Many etiologic factors for esophageal cancer have been described; in China, human papillomavirus (HPV) infection could be an important cause of esophageal cancer. Tangshan in Hebei, China has a high incidence of esophageal cancer. However, no large-sample analyses of the prevalence of HPV in this area have been performed. We analyzed the prevalence and types of HPV in 198 esophageal cancer specimens in this area of China. These findings have important significance for analysis of the various causes of local esophageal cancer.
