      <i>Background</i> - It is unclear if smoking-related DNA methylation represents a causal pathway between smoking and risk of lung cancer. We sought to identify novel smoking-related DNA methylation sites in blood, with repeated measurements, and to appraise the putative role of DNA methylation in the pathway between smoking and lung cancer development.<br><br> <i>Methods</i> - We derived a nested ...
    • Concordance between clinical and pathology TNM-staging in lung cancer 

      Solberg, Steinar; Nilssen, Yngvar; Brustugun, Odd Terje; Haram, Per Magnus; Helland, Åslaug; Møller, Bjørn; Strand, Trond-Eirik; Wahl, Sissel Gyrid Freim; Fjellbirkeland, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-25)
      Objectives: A prerequisite for utilizing the tumour, lymph-nodes, and metastases (TNM) for the staging of lung cancer patients is a high quality of the reported data on which the staging is based. The aim of this study was to investigate the concordance between the clinical, cTNM and the pathology, pTNM staging for lung cancer, version 8 as reported to the Cancer Registry of Norway (CRN).<p> < ...
    • Machine learning-based immune phenotypes correlate with STK11/KEAP1 co-mutations and prognosis in resectable NSCLC: a sub-study of the TNM-I trial

      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: ...
    • Mutasjonstesting ved ikke-småcellet lungekreft 

      Brustugun, Odd Terje; Helland, Åslaug; Fjellbirkeland, Lars; Kleinberg, Lilach; Ariansen, Sarah Louise; Jebsen, Peter Wilhelm; Scott, Helge; Dønnem, Tom; Bremnes, Roy M.; Berg, Thomas; Grønberg, Bjørn Henning; Dai, Hong Yan; Wahl, Sissel Gyrid Freim; Mangseth, Kjersti; Helgeland, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-04-30)
      Bakgrunn. Epidermal vekstfaktorreseptor (EGFR) tyrosinkinasehemmere (EGFR-TKI) er en relativt ny klasse legemidler til behandling av ikke-småcellet lungekreft. Den nasjonale faggruppen for lungekreft, Norsk Lunge Cancer Gruppe, anbefaler at pasienter med ikke-småcellet lungekreft testes for mutasjoner i EGFRgenet. Vi rapporterer her erfaringene som er gjort etter at slik testing ble innført i ...
    • 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 ...
    • Prognostic value of absolute quantification of mutated KRAS in circulating tumour DNA in lung adenocarcinoma patients prior to therapy 

      Wahl, Sissel Gyrid Freim; Hong, Yan Dai; Emdal, Elisabeth Fritzke; Ottestad, Anine Larsen; Dale, Vibeke Grotnes; Richardsen, Elin; Halvorsen, Tarje Onsøien; Grønberg, Bjørn Henning (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-27)
      Droplet digital polymerase chain reaction (ddPCR) is a highly sensitive and accurate method for quantification of nucleic acid sequences. We used absolute quantification of mutated v‐Ki‐ras2 Kirsten rat sarcoma viral oncogene homology gene (KRAS) by ddPCR to investigate the prognostic role of mutated KRAS in patients with KRAS‐mutated lung adenocarcinomas. Pre‐treatment plasma samples from 60 patients ...
