IN THIS ISSUE 2 Message from the Director 4 Our Supporters Science at the heart of medicine NEWS Einstein Cancer Center century ago, cervical cancer was the leading cancer killer of Conquering American women, but today it’s not even in the top 10. This A great progress was due mainly to better prevention, screening Cervical Cancer and treatment—and Albert Einstein Cancer Center researchers have played active roles in all of these areas. The Vaccines Some 13 different types of human papillomavirus (HPV) cause cervical cancer, but just two are responsible for most cases: HPV16 (50 percent of cases) and HPV18 (10 percent). Today, two cervical cancer vaccines—Cervarix and Gardasil—protect against HPV16 and HPV18. How do they compare? “The College of Medicine was the lead site in a postmarketing clinical trial of these vaccines and found stronger immunity with Cervarix,” says Mark Einstein, M.D., M.S. ’05, associate professor of obstetrics & gynecology and women’s health. But Gardasil has an added virtue: It not only prevents cervical cancer; it also protects against genital warts by targeting two other viruses, HPV6 and HPV11. His conclusion: Both vaccines work and can spare women from potentially debilitating disease. Newsletter of the Albert Einstein Cancer Center Above, from left: Mark H.
