Outline of Research at the Start

近年、我が国における子宮頸がん罹患率は上昇に転じている。ヒトパピローマウイルスワクチンの積極的勧奨政策を中断している我が国において、子宮頸がん検診の受診率向上は喫緊の課題である。本研究は、子宮頸がん検診未受診者に対して自己採取によるHPV-DNA検査をオプションとして提供することにより、検診受診率が向上するか否か、また、その結果、中等度異形成以上の検出率が向上するか否かを明らかにするランダム化比較試験である。

Outline of Final Research Achievements

This is the first randomized controlled trial to evaluate the effectiveness of self-sampling HPV test in Japan. Women assigned to the intervention group (n=7,337) could undergo the regular screening (cytology) or screening with self-sampling HPV test and those to the control group (n=7,772) the regular screening. Screening uptake in the intervention and control groups were 20.0% and 6.0%, respectively, and significant difference was observed. Compliance rate with cytology triage in HPV-positive women was 46.8%. Self-sampling HPV test increased screening uptake; however, no difference was observed in the detection of CIN2+ between the two groups, probably due to a low compliance rate with cytology triage. Further research is needed to identify effective strategies to ensure an adequate compliance rate before rolling out programs that include self-sampling at the national level.

Academic Significance and Societal Importance of the Research Achievements

子宮頸がんは、HPVワクチン接種と検診で予防可能な疾患であるが、我が国の予防対策は十分ではない。自己採取HPV検査は、検診受診率を向上させ、早期がんや前がん病変の検出を増加させる可能性があるが、その有効性が評価されていなかった。本研究は、自己採取HPV検査が検診受診率を向上させることを明らかにした我が国初めてのランダム化比較研究である。しかし、一方で、HPV陽性者の細胞診トリアージ検査受診率が低く、早期がんや前がん病変の検出の向上には至らなかった。自己採取HPV検査を実装するにあたっての課題が明確となった。
