Abstract
Human papillomavirus causes viral-dependent cancers, including cervical, anal, vulvar, penile, vaginal, and oropharyngeal, and condyloma acuminata. In the last decade, HPV prophylactic vaccine has been developed and spread worldwide after many large-scale clinical studies. These studies demonstrate significant clinical efficacy for prevention of HPV16/18/6/11-related diseases. In particular, prevention of cervical cancer should be the most important role in the world. In Japan, incidence of cervical cancer does not increase, but the peak of age of the patients at 2005 is 25-45 years old and became 20 years younger than that at 1985. The current two HPV vaccines can prevent the infection of HPV16/18 among high-risk HPVs and will provide a significant impact especially on young-age onset cervical cancer. Furthermore, quadrivalent HPV vaccine, Gardasil, has shown population impact that is decrease of patients with condyloma acuminate in several countries. The clinical efficacy seems to be convincing. Here HPV vaccine will be reviewed based on the literatures.
