Outline of Final Research Achievements

The specimens were available for 326 of 377 (86.5%) patients. High expression of hENT1 and DPD was observed in 100 and 63 of 326 patients (30.7% and 19.3%), respectively. In the S-1 arm, the median overall survival (OS) for the S-1-treated patients with low hENT1 was 58.0 months compared with 30.9 months for those with high hENT1, with hazard ratio of 1.75 (P = 0.007). In contrast, there were no significant differences of OS, stratified by DPD expression in the S-1 arm and hENT1 and DPD expressions in the gemcitabine arm.

Academic Significance and Societal Importance of the Research Achievements

膵癌切除後の補助化学療法は、わが国においてはS-1が第一選択肢であるが、hENT1発現陽性の患者においては、塩酸ゲムシタビンも第一選択肢となる可能性が示唆された。
mRNA発現解析によって、予後予測に有用なバイオマーカー候補が検出され、これら新規バイオマーカーを組み合わせることで、より感度の高い予後予測、個別化した補助化学療法の実施に発展できると考えられた。
