      As many as 30% to 40% of locally advanced rectal cancer (LARC) patients experience metastatic progression of the disease. Recognizing the potential of the genetic cargo in tumor-derived exosomes, we hypothesized that plasma ...
    • Comparison of Intravoxel incoherent motion imaging and multiecho dynamic contrast-based MRI in rectal cancer 

      Bakke, Kine Mari; Grøvik, Endre; Meltzer, Sebastian; Negård, Anne; Holmedal, Stein Harald; Mikalsen, Lars Tore G; Lyckander, Lars Gustav; Ree, Anne Hansen; Gjesdal, Kjell-Inge; Redalen, Kathrine; Bjørnerud, Atle (Journal article; Peer reviewed, 2019)
      Background Dynamic contrast‐based MRI and intravoxel incoherent motion imaging (IVIM) MRI are both methods showing promise as diagnostic and prognostic tools in rectal cancer. Both methods aim at measuring perfusion‐related ...
    • 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 ...
    • 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 ...
    • Learning radiation oncology in Europe: Results of the ESTRO multidisciplinary survey 

      Bibault, Jean-Emmanuel; Franco, Pierfrancesco; van Elmpt, Wouter; Thorwarth, Daniela; Schmid, Maximilian P; Rouschop, Kasper M; Spalek, Mateusz; Mullaney, Laura; Redalen, Kathrine; Dubois, Ludwig; Verfaille, Christine; Eriksen, Jesper Grau (Journal article; Peer reviewed, 2018)
      Introduction Radiotherapy education can be very different across Europe, despite the publication of the ESTRO core curricula in 2011. The purpose of the current study is to map the different RO European education systems, ...
    • 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 ...
