リンパ節郭清範囲—十二指腸乳頭部癌

著者： 廣野誠子¹ 山上裕機¹

所属機関： ¹和歌山県立医科大学第2外科

ページ範囲：P.80 - P.82

【ポイント】
◆リンパ節転移は，十二指腸乳頭部癌の独立した予後規定因子である．
◆T1 stageの十二指腸乳頭部癌でも9〜36%にリンパ節転移を認め，膵頭十二指腸切除術が必要である．
◆十二指腸乳頭部癌のリンパ節転移好発領域は，膵頭後部リンパ節（#13），膵頭前部リンパ節（#17），上腸間膜根部リンパ節（#14）であり，胆道癌取扱い規約におけるD2郭清が必要である．
◆リンパ節転移陽性の十二指腸乳頭部癌において，術後補助療法は唯一生存期間を延長できる治療である．
