      Paulsen, Erna-Elise; Kilvær, Thomas Karsten; Rakaee, Mehrdad; Al-Saad, Samer; Hald, Sigurd; Andersen, Sigve; Richardsen, Elin; Ness, Nora; Busund, Lill-Tove; Bremnes, Roy M.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-05)
      Novel immune biomarkers could complement the TNM classification for nonesmall cell cancer (NSCLC), improving the prognostic accuracy. The present study evaluated the prognostic significance of the immune checkpoint molecules programmed cell death protein 1 (PD-1) and PD-1 ligand (PD-L1) in 536 patients with stage I to IIIA NSCLC using an Immunoscore approach. Independently, and in combination, ...
    • CD4/CD8 co-expression shows independent prognostic impact in resected non-small cell lung cancer patients treated with adjuvant radiotherapy

    • CD45RO+ Memory T Lymphocytes – a Candidate Marker for TNM-Immunoscore in Squamous Non-Small Cell Lung Cancer

      Tumor-infiltrating lymphocytes (TILs) are vital in limiting cancer progression and may supplement the TNM classification. CD45RO+ memory TILs show major prognostic impact in various malignancies but have not been extensively explored in non–small cell lung cancer (NSCLC). In this study, we aimed to evaluate their potential in a NSCLC TNM-Immunoscore. Tissue microarrays were constructed from tumor ...
    • CTLA-4 expression in the non-small cell lung cancer patient tumor microenvironment: diverging prognostic impact in primary tumors and lymph node metastases 

      Paulsen, Erna-Elise; Kilvær, Thomas Karsten; Rakaee, Mehrdad; Richardsen, Elin; Hald, Sigurd; Andersen, Sigve; Busund, Lill-Tove; Bremnes, Roy M.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-13)
      The immune checkpoint receptor CTLA-4 plays a crucial part in negatively regulating T cell activation and maintaining self-tolerance. It is frequently overexpressed in a variety of malignancies, yet its prognostic impact in non-small cell lung cancer (NSCLC) remains unclear. We constructed tissue microarrays from tumor tissue samples and evaluated the immunohistochemical expression of CTLA-4 in 536 ...
    • Lymphangiogenic Markers and Their Impact on Nodal Metastasis and Survival in Non-Small Cell Lung Cancer--A Structured Review with Meta-Analysis. 

      Kilvær, Thomas Karsten; Paulsen, Erna-Elise; Hald, Sigurd; Wilsgaard, Tom; Bremnes, Roy M.; Busund, Lill-Tove (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-25)
      Background In non-small cell lung cancer (NSCLC), nodal metastasis is an adverse prognostic factor. Several mediating factors have been implied in the development of nodal metastases and investigated for predictive and prognostic properties in NSCLC. However, study results differ. In this structured review and meta-analysis we explore the published literature on commonly recognized pathways for ...
    • Prognostic impact of CXCL16 and CXCR6 in non-small cell lung cancer: Combined high CXCL16 expression in tumor stroma and cancer cells yields improved survival 

      Hald, Sigurd; Kiselev, Yury; Al-Saad, Samer; Richardsen, Elin; Johannessen, Charles; Eilertsen, Marte; Kilvær, Thomas Karsten; Al-Shibli, Khalid; Andersen, Sigve; Busund, Lill-Tove; Bremnes, Roy M.; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-05-29)
      Background: The chemokine CXCL16 and its receptor CXCR6 are expressed by a variety of immune cells and have been shown to influence angiogenesis. The expression of CXCR6 and CXCL16 has been examined in numerous human cancers; however no studies have yet investigated their influence on prognosis in non-small cell lung cancer (NSCLC). We aimed to explore their prognostic significance in NSCLC, in ...
