1. Cervical Cancer: Molecular Impact of an Infectious Disease

4. HPV-16 E6 and E7 genes interact with cell cycle machinery

7. Background Worldwide, cervical cancer is the 2nd leading cause of cancer death in women Most cervical cancer is either squamous cell (85%) or adenocarcinoma (12%) Risk factors for squamous cell cancer –Early coitarche –Greater than 6-8 partners –Cigarette smoking –Oral contraceptives

8. During the sexual lifespan of a woman, approximately 70% will have been exposed to HPV The vast majority of HPV infections will regress Primary prevention is not utilized –Stigma –High prevalence –Easy transmission

9. Cervical cancer is most strongly associated with sexually transmitted HPV infection HPV is endemic among sexually active humans HPV subtypes are classified into high and low risk groups

12. Progressive infection of Washington State University females with Human Papilloma Virus over time

13. Progressive infection over time with HPV in college age population measured from time of first intercourse

14. HPV sub-types in genital infection in female WSU cohort

18. Current management of cervical cancer is based on detection of disease-secondary prevention Papanicolaou technique for detection is flawed –Acquisition error –Preparation error –Interpretation error –Patient error –Reporting error

19. Common reasons for presentation –Abnormal vaginal bleeding, esp following intercourse (57%) –Abnormal pap smear (28%) –Low abdominal pain (9%) –Vaginal discharge (4%)

26. Normal transitioning to dysplastic epithelium in cervix, With accompanying inflammation due to poor barrier function

27. Squamous dysplasia

37. Future Topicals –Retinoids –Difluormethylornithine Development of prophylactic and therapeutic vaccines –VLP(L1/L2) –E6/E7
