- GLP-1インクレチンホルモンは、胆道系の胆管細胞へ増殖作用、抗アポトーシス作用を有する
- インクレチン・ベースの薬剤DPP-4阻害剤とGLP-1受容体アゴニストは、稀だが致死性リスク高い胆管細胞癌リスク増加の可能性有り
- 肝臓胆汁系がんのバランス不良がインクレチンベースの薬剤の大規模ランダム化対照トライアルの一部に認められたが、観察研究としてリアルワールドセッティングでの関連性検討されてなかった。
新規知見
- DPP-4阻害剤は胆管細胞癌リスク2倍
- GLP-1受容体アゴニストで同様の強度の関連性が見られたが統計学的有意性まで至らず
- インクレチン・ベース薬剤は故に、2型糖尿病で胆管細胞癌リスク増加の可能性

- * Use of first line antidiabetic drugs was considered in models, but not presented in table. This group generated 38 events and 250 340 person years, yielding an incidence rate of 15.2 (95% confidence interval 10.7 to 20.8) per 100 000 person years.
- † Per 100 000 person years.
- ‡ Adjusted for age, sex, year of cohort entry, obesity, smoking status, alcohol related disorders, Charlson comorbidity index score, inflammatory bowel disease, gallbladder disease, glycated haemoglobin (HbA1c) level, and duration of diabetes.
副作用が少ないため、頻用されるDPP-4阻害剤
あらためて、ベネフィット・リスク議論が必要
それにしても、がん部位は違うが・・・メトホルミンでは正反対の報告
:Metformin was associated with a reduced risk of HCC in a dose- response pattern. Users of both metformin and aspirin or metformin and statin had the lowest risk.
