      Knappskog, Stian; Berge, Elisabet Ognedal; Chrisanthar, Ranjan; Geisler, Stephanie; Staalesen, Vidar; Leirvaag, Beryl; Yndestad, Synnøve; de Faveri, Elise Norheim; Karlsen, Bård Ove; Wedge, David C.; Akslen, Lars A.; Lilleng, Peer Kåre; Løkkevik, Erik; Lundgren, Steinar; Østenstad, Bjørn; Risberg, Terje; Mjaaland, Ingvil; Aas, Turid; Lønning, Per Eystein (Peer reviewed; Journal article, 2015-10)
      Chemoresistance is the main obstacle to cancer cure. Contrasting studies focusing on single gene mutations, we hypothesize chemoresistance to be due to inactivation of key pathways affecting cellular mechanisms such as ...
    • DNA methylation profiling in doxorubicin treated primary locally advanced breast tumours identifies novel genes associated with survival and treatment response 

      Dejeux, Emelyne; Rønneberg, Jo A.; Solvang, Hiroko Kato; Bukholm, Ida Rashida Khan; Geisler, Stephanie; Aas, Turid; Gut, Ivo G.; Børresen-Dale, Anne-Lise; Lønning, Per Eystein; Kristensen, Vessela N.; Tost, Jörg (Peer reviewed; Journal article, 2010-03-25)
      Background: Breast cancer is the most frequent cancer in women and consists of a heterogeneous collection of diseases with distinct histopathological, genetic and epigenetic characteristics. In this study, we aimed to ...
    • EMG changes during continuous intraoperative neuromonitoring with sustained recurrent laryngeal nerve traction in a porcine model 

      Brauckhoff, Katrin; Aas, Turid; Biermann, Martin; Husby, Paul (Peer reviewed; Journal article, 2016)
      Purpose: Traction is the most common cause of injury to the recurrent laryngeal nerve (RLN) in endocrine neck surgery. The purpose of this study was to evaluate specific alterations to the electromyogram (EMG) and verify ...
    • Impact of EMG Changes in Continuous Vagal Nerve Monitoring in High-Risk Endocrine Neck Surgery 

      Brauckhoff, Katrin; Vik, Renate Kollevåg; Sandvik, Lorentz; Heimdal, John-Helge; Aas, Turid; Biermann, Martin; Brauckhoff, Michael (Peer reviewed; Journal article, 2016-03)
      Background: Continuous vagal intraoperative neuromonitoring (CIONM) of the recurrent laryngeal nerve (RLN) may reduce the risk of RLN lesions during high-risk endocrine neck surgery such as operation for large goiter ...
    • Latencies longer than 3.5 ms after vagus nerve stimulation does not exclude a nonrecurrent inferior laryngeal nerve 

      Brauckhoff, Michael; Naterstad, Helle; Brauckhoff, Katrin; Biermann, Martin; Aas, Turid (Peer reviewed; Journal article, 2014-08-28)
      Background: It has recently been reported that a signal latency shorter than 3.5 ms after electrical stimulation of the vagus nerve signify a nonrecurrent course of the inferior laryngeal nerve. We present a patient with ...
    • Olaparib monotherapy as primary treatment in unselected triple negative breast cancer 

      Eikesdal, Hans Petter; Yndestad, Synnøve; Elzawahry, Asmaa; Llop-Guevara, Alba; Gilje, Bjørnar; Blix, Egil Støre; Espelid, Helge; Lundgren, Steinar; Geisler, Jürgen; Vagstad, Geirfinn; Venizelos, Andreas; Minsaas, Laura; Leirvaag, Beryl; Gudlaugsson, Einar; Vintermyr, Olav Karsten; Aase, Hildegunn Siv; Aas, Turid; Balmaña, Judith; Serra, Violeta; Janssen, Emiel; Knappskog, Stian; Lønning, Per Eystein (Journal article; Peer reviewed, 2020)
      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 ...
    • Predictive and Prognostic Impact of TP53 Mutations and MDM2 Promoter Genotype in Primary Breast Cancer Patients Treated with Epirubicin or Paclitaxel 

      Chrisanthar, Ranjan; Knappskog, Stian; Løkkevik, Erik; Anker, Gun Birgitta; Østenstad, Bjørn; Lundgren, Steinar; Risberg, Terje; Mjaaland, Ingvil; Skjønsberg, Gudbrand; Aas, Turid; Schlichting, Ellen; Fjösne, Hans E.; Nysted, Arne; Lillehaug, Johan; Lønning, Per Eystein (Peer reviewed; Journal article, 2011-04-27)
      Background: TP53 mutations have been associated with resistance to anthracyclines but not to taxanes in breast cancer patients. The MDM2 promoter single nucleotide polymorphism (SNP) T309G increases MDM2 activity and may ...
    • Stathmin expression associates with vascular and immune responses in aggressive breast cancer subgroups 

      Askeland, Cecilie; Wik, Elisabeth; Finne, Kenneth; Birkeland, Even; Arnes, Jarle; Collett, Karin; Knutsvik, Gøril; Krüger, Kristi; Davidsen, Benedicte; Aas, Turid; Eide, Geir Egil; Stefansson, Ingunn; Foulkes, William; Akslen, Lars A. (Journal article; Peer reviewed, 2020)
      Studies indicate that stathmin expression associates with PI3K activation in breast cancer, suggesting stathmin as a marker for targetable patient subgroups. Here we assessed stathmin in relation to tumour proliferation, ...
    • TP53 status predicts long-term survival in locally advanced breast cancer after primary chemotherapy
