• Description:
  Objective
  
  To describe the human papillomavirus (HPV) genotype distribution in invasive vaginal cancers diagnosed prior to the introduction of the HPV vaccine, and evaluate if survival differed by HPV status.
  
  Methods
  
  Four population-based registries and three residual tissue repositories provided formalin-fixed, paraffin-embedded tissue from microscopically confirmed primary vaginal cancer cases diagnosed between 1994 and 2005 that were tested by L1 consensus polymerase chain reaction with type-specific hybridization in a central laboratory. Clinical, demographic, and all-cause survival data were assessed by HPV status.
  
  Results
  
  Sixty cases of invasive vaginal cancer were included. HPV was detected in 75% (45) and 25% (15) were HPV negative. HPV 16 was most frequently detected (55%, 33/60) followed by HPV 33 (18.3%, 11/60). Only one case was positive for HPV 18 (1.7%) Multiple types were detected in 15% of the cases. Vaginal cancers in women < 60 were more likely to be HPV 16 or HPV 18 positive (HPV 16/18) than older women; 77.3% vs. 44.7% (P = .038). The median age at diagnosis was younger in the HPV16/18 (59 years) group vs. other HPV positive (68 years) and no HPV (77 years) (P =.003). The HPV distribution did not significantly vary by race or ethnicity or place of residence. The 5-year unadjusted all-cause survival was 57.4% for women with HPV-positive vaginal cancers vs. 35.7% among those with HPV-negative tumors (p=0.243).
  
  Conclusion
  
  Three quarters of all vaginal cancers in the United States had HPV detected, much higher than previously found , and 57% could be prevented by current HPV vaccines, .
