New York: A new review of previous research links infection with human papillomavirus (HPV) to a three-fold greater chance of esophageal cancer."This doesn`t mean it is present in all (esophageal cancers), but it may be a factor in a certain proportion of cases," said Dr. Surabhi Liyanage, the study`s lead author.HPV is a very common sexually transmitted virus that is known to cause cervical cancer, anal cancer and some cancers of the reproductive organs and the upper throat.Liyanage, a graduate student at the University of New South Wales in Sydney, Australia, said there`s been a lot of debate among researchers about the role of HPV in cancer of the esophagus because most of the studies to date have been small and used disparate methods that make them hard to compare.According to the National Cancer Institute, nearly 18,000 people - roughly four out of every 100,000 - are diagnosed with esophageal cancer each year in the U.S. and 15,000 Americans die from it annually.
