We also identified HRR-related gene mutations and epigenetic mutations that cause HRD, and found that the presence or absence of each mutation resulted in different prognoses. We also found that the HRD score changed before and after chemotherapy, and that the HRD score was associated with BRCA1/2 mutations and the presence of LOH., 研究種目:若手研究; 研究期間:2019~2020; 課題番号:19K18713; 研究分野:婦人科腫瘍学; 科研費の分科・細目:, application/pdf}, title = {がんゲノムに基づく新たな卵巣がん薬剤感受性バイオマーカー探索}, year = {2021}, yomi = {タカヤ, ヒサミツ} }
