覚えておきたいデータ

◆非切除例の治療法と治療データ:Stage 0を除く全大腸癌症例の13~17%がStage Ⅳ症例である.標準治療法は化学療法である.化学療法が奏効して切除可能になった場合は切除を行う.

◆術後フォローアップの方法:問診,診察,CEA検査を3か月ごと(術後3年以降は半年ごと)に行う.CT検査は6か月ごとに行う.大腸内視鏡検査は,術前内視鏡(+)→術後1年目,3年目(直腸癌では2年目にも),術前内視鏡(-)→術後6か月目以内である.日米でガイドラインが異なっている.

◆再発時期,再発部位:再発率は17.3%.累積再発率は3年83.2%,4年91.6%,5年96.4%である.再発部位は,結腸およびRS癌では肝7.0%,肺3.5%,局所1.8%の順であるが,直腸癌では局所8.8%,肺7.5%,肝7.3%の順である.Stage Ⅰ,Ⅱ,Ⅲの再発率はそれぞれ3.7%,13.3%,30.8%である.

◆再発後の治療法と治療成績:非切除症例と同様である.
