Research Abstract |
平成17,18年度に引き続き、がん臨床試験における多変量生存時間データの解析方法について、実データへの適用を考慮いつつ検討した。 ・クラスターデータの解析 昨年度の胃がんの手術療法に関する多施設臨床試験データの解析に加えて、同じく胃がんの化学療法に関する多施設臨床試験データを用いて、施設間差の検討を行った。Frailtyモデルのパラメータ推定にはWinBUGSを用いた。ペナルティー付き尤度に基づく方法などと比して、ベイズ流のアプローチを用いることで安定した結果が得られ、推定の性能も良好であった。 ・多段階遷移データ及び競合危険データの解析 血液がんにおける移植療法のデータを中心に検討した。多段階遷移データに関して、GVL効果を検討するために提案されている複数の統計モデルについて比較を行った。通常用いられている、GVHDの発症を時間依存性変数として考慮したCox回帰モデルの適用には限界があると考えられたが、一方で、他の因果モデルの適用についても既存のデータを生状況が直感的に理解できるようなグラフ表示方法について検討した。また、Cumulative Incidence及び対応する回帰手法である競合危険回帰について、どのような状況において用いることが適当であるか実データに基づき検討した。競合危険回帰については、利用可能な統計パッケージについて調査した。
