A common virus, believed to be transmitted during oral sex, is the cause of a rare throat cancer in both men and women.
Were researched 100 patients with newly diagnosed oropharyngeal cancer and 200 control patients without cancer to evaluate associations between HPV(human papillomavirus) infection and oropharyngeal cancer.
Oral HPV infection is strongly associated with oropharyngeal cancer among subjects with or without the established risk factors of tobacco and alcohol use.
In this study, were focused exclusively on oropharyngeal cancer, for which the molecular evidence of a causal role for HPV is compelling.
The association with oropharyngeal cancer increased significantly with the number of vaginal-sex partners or oral-sex partners and was markedly elevated among patients with a high lifetime number of such partners .
