The epithelial–mesenchymal transition regulators Twist, Slug, and Snail are associated with aggressive tumour features and poor outcome in prostate cancer patients
Børretzen, Astrid; Gravdal, Karsten; Haukaas, Svein Andreas; Mannelqvist, Monica; Beisland, Christian; Akslen, Lars Andreas; Halvorsen, Ole Johan (Journal article; Peer reviewed, 2021)The prognostic importance of transcription factors promoting epithelial–mesenchymal transition (EMT) and angiogenesis has not been well explored in prostate cancer patients with long follow-up, nor the interplay between ... -
FOXC2 expression and epithelial–mesenchymal phenotypes are associated with castration resistance, metastasis and survival in prostate cancer
Børretzen, Astrid; Gravdal, Karsten; Haukaas, Svein Andreas; Beisland, Christian; Akslen, Lars A.; Halvorsen, Ole Johan (Peer reviewed; Journal article, 2019)Epithelial–mesenchymal transition (EMT) is important for tumour cell invasion and metastasis and is a feature of aggressive carcinomas. EMT is characterised by reduced E‐cadherin and increased N‐cadherin expression ... -

Preoperative predictors of pathological tumour stage and prognosis may be used when selecting candidates for intensified treatment in upper tract urothelial carcinoma
Almås, Bjarte; Øverby, Stein; Halvorsen, Ole Johan; Reisæter, Lars Anders Rokne; Carlsen, Birgitte; Beisland, Christian (Journal article; Peer reviewed, 2021)Purpose: Intensified treatment such as extended lymph node dissection (LND) and/or perioperative chemotherapy in addition to radical nephroureterectomy (RNU) has been suggested for high-risk cases of upper tract urothelial ... -
Ten-Year Results From a Phase II Study on Image Guided, Intensity Modulated Radiation Therapy With Simultaneous Integrated Boost in High-Risk Prostate Cancer
Ekanger, Christian; Helle, Svein Inge; Heinrich, Daniel; Johannessen, Dag Clement; Karlsdottir, Åsa; Nygård, Yngve; Halvorsen, Ole Johan; Reisæter, Lars Anders Rokne; Kvåle, Rune; Hysing, Liv Bolstad; Dahl, Olav (Journal article; Peer reviewed, 2020)Purpose There is no consensus on how to treat high-risk prostate cancer, and long-term results from hypofractionated radiation therapy are lacking. We report 10-year results after image guided, intensity modulated radiation ...
