| その他関連情報/Other related information | 希少転移乳癌において局所療法がOSに有効であるという仮説に基づいて,局所及び全身療法群と全身療法のみ群における5年全生存率をそれぞれ50%と40%と予測した。両側検定によるαエラー5%と検出力20%の場合に各群349例,合計698例のサンプルが必要である。以上から,KACO, CSCO,JSCOの3ヵ国の研究者より700例(各国234例)の症例登録が必要となる。なお,仮説の検証のために400例のイベント(死亡)を要する。 | o hypothesize that locoregional therapy has more advantage of OS in oligometastatic BC, the 5-year OS rates of cases treated with locoregional and systemic therapy and cases treated with systemic therapy alone are expected to be 50% and 40%, respectively. The estimated sample size is calculated to be the number of 698 cases (349 cases in each group) needed to prove the superiority of survival with a two-sided type I error rate of 5% and a statistical power of 80%. Thus, we need to register 700 cases, i.e., 234 cases each from investigators of KACO, CSCO and JSCO. To confirm the hypothesis, events of 400 cases should be needed.
