In addition to protecting against 80 percent of cervical cancers, the new 9-Valent human papillomavirus vaccine has the potential to protect against approximately 19,000 other cancers diagnosed in the United States – including anal, oropharyngeal and penile cancers. This is an 11.1 percent point increase in protection against HPV-related cancers in comparison to the first vaccines on the market, Gardasil and Cervarix. These findings come from a seven-center study published in the Journal of the National Cancer Institute. The Centers for Disease Control and Prevention initiated the research effort, in conjunction with Cedars-Sinai. "This is the first comprehensive study of its kind and shows the potential to not only reduce the global cancer burden, but guide clinical decision-making with regard to childhood vaccinations," said Marc T. Goodman, PhD, MPH, senior author of the study and director of Cancer Prevention and Genetics at the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute. The study found the 9-Valent vaccine, under the trademark of Gardasil-9, also has the potential to protect against an additional 5.7 percent of oropharyngeal cancers, which include the base of the tongue and tonsils. This disease is the second-most-common HPV-associated cancer. "We found that 70 percent of patient DNA tissue samples with cancer of the oropharynx harbored HPV," added Goodman. "This is a much higher percentage of HPV than observed in other studies, likely because of changes in sexual behaviors, such as increased oral-genital contact." The 9-Valent vaccine was also found to potentially increase protection from other HPV-related cancers including those of the vulva, from 48.6 to 62.8 percent; vagina, from 55.1 percent to 73.3 percent; the penis, 47.9 percent to 56.9 percent; and the anus, 79.4 percent to 87.6 percent. To compile these data, researchers examined 2,670 HPV DNA tissue samples from seven population-based cancer registries. Study authors intend to perform additional research in the future to follow up on their estimate of how well the current vaccines protect against HPV-associated cancers.
