The Management of Cervical , Vulvar and Vaginal Cancers Kerry J. Rodabaugh, M.D. Division of Gynecologic Oncology University of Nebraska Medical Center Incidence: global public health issue 450,000 – 500,000 women diagnosed each year worldwide In developing countries, it is the most common cause of cancer death 340,000 deaths in 1985 United States Incidence 15,000 women diagnosed annually 4,800 annual deaths Mortality Rates • <2/100,000: Finland, France, Greece, Israel, Japan, Korea, Spain, Thailand • 2.7/100,000: USA • 12-15.9/100,000: Chile, Costa Rica, Mexico Lifetime risk of developing cervical cancer 5% - South America 0.7% - USA Cervical CA Risk Factors • • • • • • • Early age of intercourse Number of sexual partners Smoking Lower socioeconomic status High-risk male partner Other sexually transmitted diseases Up to 70% of the U.S. population is infected with HPV Screening Guidelines for the Early Detection of Cervical Cancer, American Cancer Society 2003 • Screening should begin approximately three years after a women begins having vaginal intercourse, but no later than 21 years of age. • Screening should be done every year with regular Pap tests or every two years using liquid-based tests. • At or after age 30, women who have had three normal test results in a row may get screened every 2-3 years. However, doctors may suggest a woman get screened more if she has certain risk factors, such as HIV infection or a weakened immune system. • Women 70 and older who have had three or more consecutive Pap tests in the last ten years may choose to stop cervical cancer screening. • Screening after a total hysterectomy (with removal of the cervix) is not necessary unless the surgery was done as a treatment for cervical cancer. American Cancer Society. Cancer Facts & Figures. 2004. Atlanta, GA; 2005 Pap Smear • Single Pap false negative rate is 20%. • The latency period from dysplasia to cancer of the cervix is variable. • 50% of women with cervical cancer have never had a Pap smear. • 25% of cases and 41% of deaths occur in women 65 years of age or older.
