HPV- associated cancers

HPV Related Cancers Increase in Men

Source: scientificamerican.comAuthor: Robin Lloyd A vaccine to protect against the most dangerous strains of human papillomavirus (HPV), which cause almost all cervical cancers, as well as many cases of other cancers and genital warts in both sexes, won the approval of the U.S. Food and Drug Administration nearly nine years ago. The Centers for Disease Control and Prevention now recommends that all boys and girls aged 11 or 12 receive the shots. Vaccination campaigns, aimed largely at girls and women, have fallen short of expectations. By 2013 just over half of U.S. females aged 13 to 17 had received at least one dose of either the Gardasil or Cervarix vaccine. For males, that figure was a disappointing 35 percent. Now head and neck cancers associated with the virus are on the rise, leading some experts to recommend that a gender-neutral or male-centric approach might be more effective. HPV is the most prevalent sexually transmitted disease in the U.S. and worldwide, infecting just about all men and women at some point in their lives. Although most people clear the virus naturally, persistent infections with some strains can lead to cancer—usually cervical or oropharyngeal (affecting the back of the throat, tonsils and back of the tongue). HPV-associated cancers make up 3.3 percent of all cancer cases among women and 2 percent of all such cases among men annually in the latest available figures, yet the incidence of virally instigated oropharyngeal and anal cancers is increasing.

HPV-related cancers on the rise

Source: www.drbicuspid.com Author: Drbicuspid staff The rising incidence of cancers associated with human papillomavirus (HPV) shows a need to increase HPV vaccination coverage levels, according to a report in the Journal of the National Cancer Institute (January 7, 2013). Despite the decline in cancer death rates in the U.S., the rate of HPV-associated cancers has increased, the report noted. The American Cancer Society (ACS), the Centers for Disease Control and Prevention, the National Cancer Institute, and the North American Association of Central Cancer Registries annually provide updates on trends in cancer incidence and death rates in the U.S. This year's report highlighted trends in incidence rates for HPV-associated cancers and HPV vaccination coverage levels. Two HPV vaccines (bivalent and quadrivalent) have been shown to protect against most cervical cancers in women and one vaccine (quadrivalent) also protects against genital warts and cancers of the anus, vagina, and vulva. However, the report had no data available on the vaccine's efficacy for preventing HPV-associated cancers of the oropharynx. To assess trends in HPV-associated cancer incidence rates and HPV vaccination coverage levels, ACS researchers looked at trends in age-standardized incidence and death rates for all cancers combined and for the leading cancers among men and women. They also analyzed HPV vaccination coverage levels during 2008 and 2010. Nationally, 32% of females ages 13 to 17 years received three doses of the HPV vaccine in 2010, showing the necessity for increased efforts to increase HPV vaccination coverage, the report said. HPV vaccination efforts should [...]

CDC report releases updated information on HPV-associated cancers

Source: www.dentistryiq.com Author: staff The Centers for Disease Control and Prevention released on April 24, 2012, an updated statistical count on the prevalence of HPV-associated cancers in the United States. Oropharyngeal cancers, primarily the base of the tongue and tonsils, were the second most common after cervical cancer. Published in the April 20 edition of CDC’s Morbidity and Mortality Weekly Report (MMWR), the report, titled, ”Human Papillomavirus-Associated Cancers — United States, 2004–2008,” provides updated information from an analysis of data for all 50 states and the District of Columbia from the National Program of Cancer Registries (NPCR) and the Surveillance, Epidemiology and End Results (SEER) program. An average of 33,369 HPV-associated cancers were diagnosed annually (rate = 10.8 per 100,000 population), including 11,726 cases of oropharyngeal cancers. CDC estimates that about 7,400—63%—of the cases of oropharyngeal cancer each year were attributable to HPV infection. These cancers were found three times more frequently among men.

Needed: HPV vaccine, simple screening test, for women and men

Source: jhu.edu/~gazette Author: Valerie Mehl, Johns Hopkins Medicine A call to explore a broader use of human papillomavirus vaccines and the validation of a simple oral screening test for HPV-caused oral cancers are reported in two studies by an investigator at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins. Leading HPV expert Maura Gillison, the first to identify HPV infection as the cause of certain oral cancers and who identified multiple sex partners as the most important risk factor for these cancers, reports her latest work Nov. 3 in the journal Clinical Cancer Research and in a Centers for Disease Control and Prevention monograph. The CDC report on HPV-associated cancers appears online Nov. 3 and in the Nov. 15 supplement edition of Cancer. In the CDC report, believed to be the first and most comprehensive assessment of HPV-associated cancer data in the United States, investigators analyzed cancer registry data from 1998 to 2003 and found 25,000 cancer cases each year occurred at cancer sites associated with HPV infection. In additional analysis, Gillison and colleagues at the National Cancer Institute identified HPV infection as the underlying cause of approximately 20,000 of these cancers. Gillison and her team found that approximately 20,000 cases of cancer in the United States each year are caused by HPV infection. Oral cancers are the second most common type of HPV- associated cancers and are increasing in incidence in the United States, particularly among men. Add to that anal, penile, vaginal and vulvar cancers that are [...]
