      Purpose Homologous recombination deficiency (HRD) is highly prevalent in triple-negative breast cancer (TNBC) and associated with response to PARP inhibition (PARPi). Here, we studied the prevalence of HRD in non-TNBC to ...

      Background The antitumor efficacy of PARP inhibitors (PARPi) for breast cancer patients harboring germline BRCA1/2 (gBRCA1/2) mutations is well established. While PARPi monotherapy was ineffective in patients with metastatic ...
    • Prenatal BRCA1 epimutations contribute significantly to triple-negative breast cancer development 

      Nikolaienko, Oleksii; Eikesdal, Hans Petter; Berge, Elisabet Ognedal; Gilje, Bjørnar; Lundgren, Steinar; Blix, Egil Støre; Espelid, Helge; Geisler, Jürgen; Geisler, Stephanie; Janssen, Emiel; Yndestad, Synnøve; Minsaas, Laura; Leirvaag, Beryl; Lillestøl, Reidun Kristine; Knappskog, Stian; Lønning, Per Eystein (Peer reviewed; Journal article, 2023)
      Background Normal cell BRCA1 epimutations have been associated with increased risk of triple-negative breast cancer (TNBC). However, the fraction of TNBCs that may have BRCA1 epimutations as their underlying cause is ...
