    • Age-Related Clusters and Favorable Immune Phenotypes in Breast Cancer of the Young Patients 

      Ingebriktsen, Lise Martine; Svanøe, Amalie Abrahamsen; Sæle, Anna Kristine Myrmel; Humlevik, Rasmus Olai Collett; Toska, Karen; Kalvenes, May Britt; Aas, Turid; Heie, Anette; Askeland, Cecilie; Knutsvik, Gøril; Stefansson, Ingunn Marie; Akslen, Lars Andreas; Høivik, Erling André; Wik, Elisabeth (Journal article; Peer reviewed, 2024)
      Breast cancer (BC) patients aged <40 years at diagnosis experience aggressive disease and poorer survival compared with women diagnosed with BC at 40 to 49 years, but the age-related biology is described to little extent. ...

    • Age-related phenotypes in breast cancer: A population-based study 

      Svanøe, Amalie Abrahamsen; Humlevik, Rasmus Olai Collett; Knutsvik, Gøril; Sæle, Anna Kristine Myrmel; Askeland, Cecilie; Ingebriktsen, Lise Martine; Hugaas, Ulrikke; Kvamme, Amalie Bark; Tegnander, Amalie Fagerli; Krüger, Kristi; Davidsen, Benedicte; Høivik, Erling André; Aas, Turid; Stefansson, Ingunn Marie; Akslen, Lars Andreas; Wik, Elisabeth (Journal article; Peer reviewed, 2024)
      Breast cancer in young (<40 years) is associated with a higher frequency of aggressive tumor types and poor prognosis. It remains unclear if there is an underlying age-related biology that contributes to the unfavorable ...

    • Biomarkers in breast cancer, with special focus on tumor cell proliferation 

      Knutsvik, Gøril (Doctoral thesis, 2016-10-31)
      Background: Breast cancer is a heterogeneous disease encompassing distinct subtypes that differ in incidence and prognosis. Better characterization of established biomarkers and exploration of novel biomarkers and possible ...

    • Detection and significance of small and low proliferation breast cancer 

      Hofvind, Solveig; Knutsvik, Gøril; Holen, Åsne Sørlien; Tsuruda, Kaitlyn; Akslen, Lars Andreas (Journal article; Peer reviewed, 2022)
      Objectives To determine the frequency and discuss possible implications of early breast cancer with particularly good prognosis and defined by tumor diameter and cell proliferation. Setting Detection of small and ...

    • Evaluation of Ki67 expression across distinct categories of breast cancer specimens: A Population-based study of matched surgical specimens, core needle biopsies and tissue microarrays 

      Knutsvik, Gøril; Stefansson, Ingunn; Aziz, Sura Mohammed; Arnes, Jarle; Eide, Johan; Collett, Karin; Akslen, Lars A. (Peer reviewed; Journal article, 2014-11-06)
      Introduction: Tumor cell proliferation in breast cancer is strongly prognostic and may also predict response to chemotherapy. However, there is no consensus on counting areas or cut-off values for patient stratification. ...

    • Hypoxia induced responses are reflected in the stromal proteome of breast cancer 

      Kjølle, Silje; Finne, Kenneth; Birkeland, Even; Ardawatia, Vandana; Winge, Ingeborg; Aziz, Sura Mohammed; Knutsvik, Gøril; Wik, Elisabeth; Paulo, Joao A.; Vethe, Heidrun; Kleftogiannis, Dimitrios; Akslen, Lars Andreas (Journal article; Peer reviewed, 2023)
      Cancers are often associated with hypoxia and metabolic reprogramming, resulting in enhanced tumor progression. Here, we aim to study breast cancer hypoxia responses, focusing on secreted proteins from low-grade (luminal-like) ...

    • Integrin α11β1 is expressed in breast cancer stroma and associates with aggressive tumor phenotypes 

      Smeland, Hilde Ytre-Hauge; Askeland, Cecilie; Wik, Elisabeth; Knutsvik, Gøril; Molven, Anders; Edelmann, RJ; Reed, Rolf K.; Warren, DJ; Gullberg, Donald; Stuhr, Linda Elin Birkhaug; Akslen, Lars A. (Peer reviewed; Journal article, 2020)
      Cancer‐associated fibroblasts are essential modifiers of the tumor microenvironment. The collagen‐binding integrin α11β1 has been proposed to be upregulated in a pro‐tumorigenic subtype of cancer‐associated fibroblasts. ...

    • PRSS2 remodels the tumor microenvironment via repression of Tsp1 to stimulate tumor growth and progression 

      Sui, Lufei; Wang, Suming; Ganguly, Debolina; El Rayes, Tyler P.; Askeland, Cecilie; Børretzen, Astrid; Sim, Danielle; Halvorsen, Ole Johan; Knutsvik, Gøril; Arnes, Jarle; Aziz, Sura Mohammed; Haukaas, Svein Andreas; Foulkes, William D.; Bielenberg, Diane R.; Ziemys, Arturas; Mittal, Vivek; Brekken, Rolf A.; Akslen, Lars Andreas; Watnick, Randolph (Journal article; Peer reviewed, 2022)
      The progression of cancer from localized to metastatic disease is the primary cause of morbidity and mortality. The interplay between the tumor and its microenvironment is the key driver in this process of tumor progression. ...

    • 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, ...

    • Vessel size as a marker of survival in estrogen receptor positive breast cancer 

      Milosevic, Vladan; Edelmann, Reidunn Jetne; Winge, Ingeborg; Strell, Carina; Mezheyeuski, Artur; Knutsvik, Gøril; Askeland, Cecilie; Wik, Elisabeth; Akslen, Lars Andreas; Östman, Arne (Journal article; Peer reviewed, 2023)
      Purpose: Angiogenesis is crucial for tumor growth and is one of the hallmarks of cancer. In this study, we analyzed microvessel density, vessel median size, and perivascular a-SMA expression as prognostic biomarkers in ...
