• Androgen receptor expression in breast cancer subtypes 

      Kraby, Maria Ryssdal (Master thesis, 2016)
      Background The androgen receptor (AR) is frequently expressed in breast cancer, and associated with good prognosis in ER-positive breast cancers. Due to its high prevalence, AR is also a possible target for therapeutic ...
    • Basal markers and prognosis in luminal breast cancer 

      Engstrøm, Monica J; Valla, Marit; Bofin, Anna M. (Journal article; Peer reviewed, 2017)
      Purpose Basal marker expression in triple-negative breast cancers identifies basal-like tumours, and thus separates the TN group into two prognostic groups. However, the expression and prognostic significance of basal ...
    • Characterization of FGD5 expression in primary breast cancers and lymph node metastases 

      Valla, Marit; Mjønes, Patricia; Engstrøm, Monica J; Ytterhus, Borgny; Bordin, Diana Lilian; van Loon, Barbara; Akslen, Lars A.; Vatten, Lars Johan; Opdahl, Signe; Bofin, Anna M. (Journal article; Peer reviewed, 2018)
      Faciogenital dysplasia 5 (FGD5) amplification drives tumor cell proliferation, and is present in 9.5% of breast cancers. We describe FGD5 expression, assess associations between FGD5 amplification and FGD5 expression, and ...
    • FGD5 amplification in breast cancer patients is associated with tumor proliferation and a poorer prognosis 

      Valla, Marit; Engstrøm, Monica J; Ytterhus, Borgny; Hansen, Åse Kristin Skain; Akslen, Lars A.; Vatten, Lars Johan; Opdahl, Signe; Bofin, Anna M. (Journal article; Peer reviewed, 2017)
      Purpose Proliferation is a hallmark of cancer. Using a combined genomic approach, FGD5 amplification has been identified as a driver of proliferation in Luminal breast cancer. We aimed to describe FGD5 copy number change ...
    • Molecular subtypes of breast cancer: incidence and prognosis 

      Valla, Marit (Doctoral theses at NTNU;2017:276, Doctoral thesis, 2017)
      Forekomsten av brystkreft har over flere tiår økt i den vestlige verden, og i Norge har det vært en dobling av insidensen siden Kreftregisteret startet sin overvåkning av antall krefttilfeller i Norge i 1952. I Norge har ...
    • Molecular Subtypes of Breast Cancer: Long-term Incidence Trends and Prognostic Differences 

      Valla, Marit; Vatten, Lars Johan; Engstrøm, Monica J; Haugen, Olav Anton; Akslen, Lars A.; Bjørngaard, Johan Håkon; Hagen, Anne Irene; Ytterhus, Borgny; Bofin, Anna M.; Opdahl, Signe (Journal article; Peer reviewed, 2016)
      Background: Secular trends in incidence and prognosis of molecular breast cancer subtypes are poorly described. We studied long-term trends in a population of Norwegian women born 1886–1977. Methods: A total of 52,949 ...
    • MRPS23 amplification and gene expression in breast cancer; association with proliferation and the non-basal subtypes 

      Klæstad, Elise; Opdahl, Signe; Engstrøm, Monica J; Ytterhus, Borgny; Wik, Elisabeth; Bofin, Anna Mary; Valla, Marit (Peer reviewed; Journal article, 2020)
      Purpose MRPS23 is recognized as a driver of proliferation in luminal breast cancer. The aims of the present study were to describe MRPS23 copy number change in breast cancer, and to assess associations between MRPS23 ...
    • The prognostic value of androgen receptors in breast cancer subtypes 

      Kraby, Maria Ryssdal; Valla, Marit; Opdahl, Signe; Haugen, Olav Anton; Sawicka, Joanna Ewa; Engstrøm, Monica J; Bofin, Anna M. (Journal article; Peer reviewed, 2018)
      Purpose Androgen receptor (AR) expression is frequent in breast cancer and has been associated with good prognosis in several studies. The present study investigates AR-expression in relation to molecular subtypes, ...
