Research Abstract

非小細胞肺がん(NSCLC)において、上皮成長因子受容体(EGFR)遺伝子異常の有無により、NSCLC患者の背景因子・臨床上の特徴が異なる。EGFR遺伝子異常の有無により、がん罹患リスク要因が異なるか否かを症例対象研究により検証した。353名のNSCLC症例と、1765名の非がん対照者を研究対象とし、半定量的食物摂取頻度調査による各種食品群の推定摂取量とリスクの関連を検討した。
EGFR遺伝子変異のないNSCLCでは、緑黄色野菜が防御要因、果物も同傾向を示した。これはEGFR遺伝子変異の無いNSCLCが喫煙によるリスク上昇を認める点と合致した。一方EGFR遺伝子変異の伴うNSCLCでは、豆類摂取が予防的な傾向を示した。既報研究において、この種類のNSCLCはエストロゲン曝露の代替指標と正の相関を示していたことを考えると、乳がんなどのような、エストロゲンとの関連が示唆された。しかしながら、エストロゲン代謝関連遺伝子の遺伝子多型との関連では著明な関連は認められず、喫煙と関連が報告されているCYP1A1遺伝子多型がEGFR変異のないNSCLCにおいてのみ頻度上昇を認めた。
今後更に詳細な検討を行い、NSCLCの背後にあるメカニズムえに影響を与えうる環境・遺伝的因子の検討を行う必要がある。
