• Diffusion-weighted magnetic resonance imaging of rectal cancer: tumour volume and perfusion fraction predict chemoradiotherapy response and survival 

      Bakke, Kine Mari; Hole, Knut Håkon; Dueland, Svein; Kotanska-Grøholt, Krystyna; Flatmark, Kjersti; Ree, Anne Hansen; Seierstad, Therese; Redalen, Kathrine Røe (Journal article, 2017)
      Background: In locally advanced rectal cancer (LARC), responses to preoperative treatment are highly heterogeneous and more accurate diagnostics are likely to enable more individualised treatment approaches with improved ...
    • High level of circulating vitamin D during neoadjuvant therapy may lower risk of metastatic progression in high-risk rectal cancer 

      Abrahamsson, Hanna Josefine; Porojnicu, Alina Carmen; Lindstrøm, Jonas Christoffer; Dueland, Svein; Flatmark, Kjersti; Hole, Knut Håkon; Seierstad, Therese; Moan, Johan Emilian; Redalen, Kathrine; Meltzer, Sebastian; Ree, Anne Hansen (Journal article; Peer reviewed, 2019)
      Background:Following curative-intent neoadjuvant therapy in locally advanced rectal cancer, metastaticprogression is still dominant. We investigated if patients’circulating 25-hydroxyvitamin D [25(OH)D] levels wereassociated ...
    • High level of circulating vitamin D during neoadjuvant therapy may lower risk of metastatic progression in high-risk rectal cancer 

      Abrahamsson, Hanna Josefine; Porojnicu, Alina Carmen; Lindstrøm, Jonas Christoffer; Dueland, Svein; Flatmark, Kjersti; Hole, Knut Håkon; Seierstad, Therese; Moan, Johan Emilian; Redalen, Kathrine Røe; Meltzer, Sebastian; Ree, Anne Hansen (Journal article; Peer reviewed, 2019)
      Background: Following curative-intent neoadjuvant therapy in locally advanced rectal cancer, metastatic progression is still dominant. We investigated if patients’ circulating 25-hydroxyvitamin D [25(OH)D] levels were ...
    • Immunogenic cell death by neoadjuvant oxaliplatin and radiation protects against metastatic failure in high-risk rectal cancer. 

      Bains, Simer Jit; Abrahamsson, Hanna Josefine; Flatmark, Kjersti; Dueland, Svein; Hole, Knut Håkon; Seierstad, Therese; Redalen, Kathrine; Meltzer, Sebastian; Ree, Anne Hansen (Journal article; Peer reviewed, 2019)
      Objective High rates of systemic failure in locally advanced rectal cancer call for a rational use of conventional therapies to foster tumor-defeating immunity. Methods We analyzed the high-mobility group box-1 ...
    • Markers of mitochondrial metabolism in tumor hypoxia, systemic inflammation, and adverse outcome of rectal cancer 

      Bousquet, Paula; Meltzer, Sebastian; Sønstevold, Linda; Esbensen, Qin Ying; Dueland, Svein; Flatmark, Kjersti; Sitter, Beathe; Bathen, Tone Frost; Seierstad, Therese; Redalen, Kathrine; Eide, Lars; Ree, Anne Hansen (Journal article; Peer reviewed, 2019)
      Tumor hypoxia contributes to therapy resistance and metastatic progression of locally advanced rectal cancer (LARC). We postulated that the tumor mitochondrial metabolism, manifested by reactive oxygen species (ROS) and ...
    • MRI-based automatic segmentation of rectal cancer using 2D U-Net on two independent cohorts 

      Knuth, Franziska Hanna; Adde, Ingvild Askim; Huynh, Bao Ngoc; Grøndahl, Aurora Rosvoll; Winter, René; Negård, Anne; Holmedal, Stein Harald; Meltzer, Sebastian; Ree, Anne Hansen; Flatmark, Kjersti; Dueland, Svein; Hole, Knut Håkon; Seierstad, Therese; Redalen, Kathrine; Futsæther, Cecilia Marie (Peer reviewed; Journal article, 2021)
      Background Tumor delineation is time- and labor-intensive and prone to inter- and intraobserver variations. Magnetic resonance imaging (MRI) provides good soft tissue contrast, and functional MRI captures tissue properties ...
    • Sex-related differences in primary metastatic site in rectal cancer; associated with hemodynamic factors? 

      Meltzer, Sebastian; Bakke, Kine Mari; Rød, Karina Lund; Negård, Anne; Flatmark, Kjersti; Solbakken, Arne Mide; Kristensen, Annette Torgunrud; Fuglestad, Anniken Jørlo; Kersten, Christian; Dueland, Svein; Seierstad, Therese; Hole, Knut Håkon; Lyckander, Lars Gustav; Larsen, Finn Ole; Schou, Jakob Vasehus; Brown, Dawn; Abrahamsson, Hanna Josefine; Redalen, Kathrine; Ree, Anne Hansen (Journal article; Peer reviewed, 2019)
      Background and purpose We investigated how features relating to pelvic cavity anatomy and tumor hemodynamic factors may influence systemic failure in rectal cancer. Materials and methods Rectal cancer patients (207 ...
    • Systemic immune response induced by oxaliplatin-based neoadjuvant therapy favours survival without metastatic progression in high-risk rectal cancer 

      Kalanxhi, Ert; Meltzer, Sebastian; Schou, Jakob Vasehus; Larsen, Finn Ole; Dueland, Svein; Flatmark, Kjersti; Jensen, Benny Vittrup; Hole, Knut Håkon; Seierstad, Therese; Redalen, Kathrine; Nielsen, Dorte Lisbet; Ree, Anne Hansen (Journal article; Peer reviewed, 2018)
      Background Systemic failure remains a challenge in rectal cancer. We investigated the possible systemic anti-tumour immune activity invoked within oxaliplatin-based neoadjuvant therapy. Methods In two high-risk patient ...
