Outline of Final Research Achievements

In this study, we aimed to propose a new method of utilizing evidence that allows for treatment selection reflecting individual patient values by using Generalized Pairwise Comparison (GPC), a method proposed for evaluating risk-benefit in clinical trials. We evaluated the performance of GPC based on literature reviews and theoretical considerations, and conducted a real data analysis comparing S-1 and 5FU using data from the GASTRIC study, an international collaborative IPD (Individual Patient/Participant Data) meta-analysis of advanced and recurrent gastric cancer. The results indicated that S-1 is a superior treatment to 5FU, demonstrating the usefulness of GPC-based risk-benefit evaluation.

Academic Significance and Societal Importance of the Research Achievements

ランダム化比較試験に対する既存の個人データがデータベース化されることにより、GPCを用いたエビデンスの再評価を行うことによって、エビデンスを利用する患者の優先順位や選考を反映させた評価が可能となることを示した。これにより、利用者の観点に立った新しいエビデンスの利用方法を示すことにつながった。
