Updating the natural history of hpv and anogenital cancer

Our objective was to use a well-documented natural history disease simulation model to explicitly identify the age distribution at which individuals acquire their causal HPV infection in the absence of HPV vaccination or screening in order to help guide the optimal use of both.

This model, which is continually updated and refined using emerging empirical data, is well published and has informed cervical cancer prevention policy worldwide [11–16].

However, how these intermediate endpoints translate to prevention of cervical cancer is not known and unlikely to be observed directly through clinical trials.

Furthermore, HPV genotypes targeted by the first-generation vaccines (i.e., HPV16 and HPV18) contribute to a smaller proportion of cancers that develop after age 50 years, resulting in a lower maximum clinical benefit of vaccinating older women [6, 7].

We assumed 95% efficacy against incident vaccine-targeted HPV infections with lifelong durability for both the first-generation bivalent and quadrivalent vaccines that target HPV16 and HPV18 oncogenic genotypes and the second-generation nonavalent vaccine that targets HPV16, 18, 31, 33, 45, 52, and 58 oncogenic genotypes.

In sensitivity analysis, we evaluated the impact of 2 HPV vaccine durability scenarios on the lifetime reductions in cervical cancer incidence.

Importantly, the age distribution varied by HPV genotype (Figure 2, right panel) where causal HPV16 infections were generally acquired at a younger age relative to non-HPV16 infections.

  1. She left her husband to move in with another guy she was playing a game with, convinced my husband that she left for him. She doesn’t care who she hurts so long as she is happy. She ruins marriages for fun because she’s a lowlife in search of other low-life scum to fu*k. This hoe has no problems hooking up with married men and tearing families apart. She starts by befriending the men and from there she makes her move. On multiple occasions, she’s been asked to back off but that seems to just encourage her even more. De Cook has been engaged in the past and it doesn’t stop her sleazy ways.
