がん関連血栓症(CAT)

著者: 岡亨1

ページ範囲:P.712 - P.717

Point

●担がん患者は,がんおよびがん治療の影響で凝固亢進状態となり,がん関連血栓症(CAT)を発症するリスクが高い.がん患者を診察する際にはCATの存在を意識する必要がある.

●CATは浮腫や下肢の痛み,呼吸苦など症候性に発見されるだけではなく,造影CTなどの画像検査で無症候性に偶然,発見される場合もある.

●化学療法前のCATリスク評価としてさまざまなスコアリングが提案されているが,実臨床では個々のがん患者を注意深く観察し,Dダイマーの経時的変化や画像検査を併用して評価している.

●CATに対する抗凝固療法は,がん患者の状態や出血リスクなどを考慮したうえで,ヘパリン〔わが国では未分画ヘパリン(UFH)〕,直接経口抗凝固薬(DOAC),ワルファリンから選択される.
