Baseline values for HPV type prevalence in cases of cervical cancer are important because these can reveal whether the types in cancers are changing as more of the population is vaccinated and whether new vaccines are targeting the correct types. A meta-analysis looked at papers published between 1990 and 2010 on more than 30,000 cervical cancer cases. 4 The most common HPV types found, in order of decreasing prevalence, were HPV 16 (57 percent), 18 (16 percent), 58 ( percent), 33 ( percent), 45 ( percent), 31, 52, and 35. In addition, more specimens than in previous studies showed infection with. | ENVIRONMENTAL CARCINOGENS This column is provided to help practitioners discuss potential environmental and workplace carcinogens offering reassurance when patients fears are unfounded and focusing legitimate concern when they are warranted. Agent Orange and Cancer An Overview for Clinicians Howard Frumkin MD DrPH ABSTRACT Approximately 3 million Americans served in the armed forces in Vietnam during the Vietnam War. Some of them as well as some Vietnamese combatants and civilians and members of the armed forces of other nations were exposed to defoliant mixtures including Agent Orange. Evidence suggests some lasting health effects from these exposures including certain cancers. This article reviews the evidence on cancer risk after Agent Orange exposure. Data sources include studies of Vietnam veterans workers occupationally exposed to herbicides or dioxins since dioxins contaminated the herbicide mixtures used in Vietnam and Dr. Frumkin is Professor and Chair Department of Environmental and Occupational Health Rollins School of Public Health Emory University and Professor of Medicine Emory Medical School Atlanta GA. The article is available online at http Vietnamese populations. The article then reviews clinical issues that arise when caring for cancer patients who may have sustained Agent Orange exposure or others concerned about such exposure to Agent Orange such as available benefits programs and sources of information and counseling.
