Outline of Final Research Achievements |
Cervical screening has been shown to reduce incidence and mortality from cervical cancer. However, high uptake is important. Therefore, the WHO recommends uptake of 80%. Many countries are now moving from a cytology to an HPV-based screening program. Reasons for this are higher sensitivity which provides women with greater reassurance of being at very low risk of cancer if they test HPV negative, as well as reducing harm from over-screening. HPV testing also has higher sensitivity on self-collected samples helping reach under/never screened women. In this study we found that unlike in many high income countries with screening programs, In Japan, the biggest factor influencing reductions in national mortality rates was not changing from a cytology to an HPV-based screening program, but increasing screening uptake to levels recommended by the WHO. However, unlike cytology based screening programs HPV testing allows for a self-sampling to be taken, which could help increase uptake.

Academic Significance and Societal Importance of the Research Achievements |
英国やオーストラリアのような先進国とは異なり、日本における子宮頸がんによる死亡者数を減少させる最も重要な要因は、どの検診法が用いられるかではなく受診率の向上であることを本研究で示すことができた点は意義深い。HPV検査は多くの国で検診受診率の向上が示されており、細胞診とは異なって自己採取検査が可能である。したがって、子宮頸がん検診ガイドラインが見直されるときには、HPV検査を正式に推奨べきであると考えられる。
