    • Expression of S100A4, ephrin-A1 and osteopontin in non-small cell lung cancer 

      Rud, Ane Kristine Kongsgaard; Lund-Iversen, Marius; Berge, Gisle; Brustugun, Odd Terje; Solberg, Steinar; Mælandsmo, Gunhild; Pedersen, Kjetil Boye (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      The metastasis-promoting protein S100A4 induces expression of ephrin-A1 and osteopontin in osteosarcoma cell lines. The aim of this study was to investigate S100A4-mediated stimulation of ephrin-A1 and osteopontin in non-small cell lung cancer (NSCLC) cell lines, and to characterize the expression of these biomarkers in primary tumor tissue from NSCLC patients. Four NSCLC cell lines were treated ...

    • Impact of KRAS, BRAF and microsatellite instability status after cytoreductive surgery and HIPEC in a national cohort of colorectal peritoneal metastasis patients 

      Larsen, Stein; Goscinski, Mariusz Adam; Dueland, Svein; Steigen, Sonja Eriksson; Hofsli, Eva; Kristensen, Annette Torgunrud; Lund-Iversen, Marius; Dagenborg, Vegar Johansen; Flatmark, Kjersti; Sørbye, Halvdan (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-09)
      Background - Patients with metastatic colorectal cancer (mCRC) carrying BRAF (mutBRAF) or KRAS mutation (mutKRAS) have an inferior prognosis after liver or lung surgery, whereas the prognostic role in the context of peritoneal metastasis (PM) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been less investigated.<p> <p>Methods - In total, 257 patients ...

    • Low Concordance Between T-Cell Densities in Matched Primary Tumors and Liver Metastases in Microsatellite Stable Colorectal Cancer 

      Johansen Dagenborg, Vegard; Marshall, Serena Elizabeth; Grzyb, Krzyzstof; Fretland, Åsmund Avdem; Lund-Iversen, Marius; Mælandsmo, Gunhild Mari; Hansen Ree, Anne; Edwin, Bjørn; Yaqub, Sheraz; Flatmark, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-09)
      Background: The subtype, density and location of tumor infiltrating T-cells are being explored as prognostic and predictive biomarkers in primary colorectal cancer (pCRC) and colorectal liver metastases (CLM). Very limited data exist comparing findings in pCRC and matched CLM.<p> <p>Patients and methods: Fifty-eight patients with available pCRC and matched CLM (57/58 microsatellite stable) were ...

    • Machine learning-based immune phenotypes correlate with STK11/KEAP1 co-mutations and prognosis in resectable NSCLC: a sub-study of the TNM-I trial 

      Rakaee, Mehrdad; Andersen, S.; Giannikou, K.; Paulsen, Erna-Elise; Kilvær, Thomas Karsten; Rasmussen Busund, Lill-Tove; Berg, Thomas; Richardsen, Elin; Lombardi, Ana Paola; Adib, E.; Pedersen, Mona Irene; Tafavvoghi, Masoud; Wahl, Sissel Gyrid Freim; Petersen, R.H.; Bondgaard, A.L.; Yde, C.W.; Baudet, C.; Licht, P.; Lund-Iversen, Marius; Grønberg, Bjørn Henning; Fjellbirkeland, Lars; Helland, Åslaug; Pøhl, M.; Kwiatkowski, D.J.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-24)
      Background - We aim to implement an immune cell score model in routine clinical practice for resected non-small-cell lung cancer (NSCLC) patients (NCT03299478). Molecular and genomic features associated with immune phenotypes in NSCLC have not been explored in detail.<p> <p>Patients and methods - We developed a machine learning (ML)-based model to classify tumors into one of three categories: ...

    • Molecularly matched therapy in the context of sensitivity, resistance, and safety; patient outcomes in end-stage cancer - the MetAction study 

      Ree, Anne Hansen; Nygaard, Vigdis; Pedersen, Kjetil Boye; Heinrich, Daniel; Dueland, Svein; Bergheim, Inger Riise; Johansen, Christin; Beiske, Klaus; Negård, Anne; Lund-Iversen, Marius; Nygaard, Vegard; Hovig, Eivind; Nakken, Sigve; Nasser, Salah; Julsrud, Lars; Reisse, Claudius; Ruud, Espen Asak; Kristensen, Vessela N.; Flørenes, Vivi Ann; Geitvik, Gry; Lingjærde, Ole Christian; Børresen-Dale, Anne-Lise; Russnes, Hege Elisabeth Giercksky; Mælandsmo, Gunhild Mari; Flatmark, Kjersti (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-25)
      <i>Background</i>: In precision cancer medicine, the challenge is to prioritize DNA driver events, account for resistance markers, and procure sufficient information for treatment that maintains patient safety. The MetAction project, exploring how tumor molecular vulnerabilities predict therapy response, first established the required workflow for DNA sequencing and data interpretation (2014–2015). ...

    • Osteopontin is a prognostic biomarker in non-small cell lung cancer 

      Rud, Ane Kristine Kongsgaard; Pedersen, Kjetil Boye; Øijordsbakken, Miriam; Lund-Iversen, Marius; Halvorsen, Ann Rita; Solberg, Steinar; Berge, Gisle; Helland, Åslaug; Brustugun, Odd Terje; Mælandsmo, Gunhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: In a previously published report we characterized the expression of the metastasis-associated proteins S100A4, osteopontin (OPN) and ephrin-A1 in a prospectively collected panel of non-small cell lung cancer (NSCLC) tumors. The aim of the present follow-up study was to investigate the prognostic impact of these potential biomarkers in the same patient cohort. In addition, circulating ...

    • The prognostic effect of KRAS mutations in non-small cell lung carcinoma revisited: A norwegian multicentre study 

      Wahl, Sissel Gyrid Freim; Hong, Yan Dai; Emdal, Elisabeth Fritzke; Berg, Thomas; Halvorsen, Tarje Onsøien; Ottestad, Anine Larsen; Lund-Iversen, Marius; Brustugun, Odd; Førde, Dagny; Paulsen, Erna-Elise; Donnem, Tom; Andersen, Sigve; Grønberg, Bjørn Henning; Richardsen, Elin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)
      Background: due to emerging therapeutics targeting KRAS G12C and previous reports with conflicting results regarding the prognostic impact of KRAS and KRAS G12C in non-small cell lung cancer (NSCLC), we aimed to investigate the frequency of KRAS mutations and their associations with clinical characteristics and outcome. Since mutation subtypes have different preferences for downstream pathways, we ...

    • Protein kinase C isozymes associated with relapse free survival in non-small cell lung cancer patients 

      Halvorsen, Ann Rita; Haugen, Mads Haugland; Øjlert, Åsa Kristina; Lund-Iversen, Marius; Jørgensen, Lars Hilmar; Solberg, Steinar; Mælandsmo, Gunhild Mari; Brustugun, Odd Terje; Helland, Åslaug (Journal article; Tidsskriftartikkel, 2020-11-25)
      <i>Introduction</i>: Protein expression is deregulated in cancer, and the proteomic changes observed in lung cancer may be a consequence of mutations in essential genes. The purpose of this study was to identify protein expression associated with prognosis in lung cancers stratified by smoking status, molecular subtypes, and EGFR-, TP53-, and KRAS-mutations.<p> <p><i>Methods</i>: We performed ...
