    • Cleavage of the urokinase receptor (uPAR) on oral cancer cells: Regulation by transforming growth factor - beta1 (TGF-beta1) and potential effects on migration and invasion 

      Magnussen, Synnøve; Hadler-Olsen, Elin Synnøve; Costea, Daniela Elena; Berg, Eli; Cavalcanti Jacobsen, Cristiane de Albuquerque; Mortensen, Bente; Salo, Tuula; Martinez, Inigo Zubiavrre; Winberg, Jan-Olof; Uhlin-Hansen, Lars; Svineng, Gunbjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)
      Background: Urokinase plasminogen activator (uPA) receptor (uPAR) is up-regulated at the invasive tumour front of human oral squamous cell carcinoma (OSCC), indicating a role for uPAR in tumour progression. We previously observed elevated expression of uPAR at the tumour-stroma interface in a mouse model for OSCC, which was associated with increased proteolytic activity. The tumour microenvironment ...

    • A combined histo-score based on tumor differentiation and lymphocytic infiltrate is a robust prognostic marker for mobile tongue cancer 

      Bjerkli, Inger-Heidi; Hadler-Olsen, Elin Synnøve; Nginamau, Elisabeth Sivy; Laurvik, Helene; Søland, Tine Merete; Costea, Daniela Elena; Uhlin-Hansen, Lars; Steigen, Sonja Eriksson (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-30)
      We wanted to evaluate the prognostic value of common histopathological variables in a large cohort of patients with cancer in the mobile tongue as such information can be important for treatment stratification of the individual patient, especially for patients with low-stage disease. In addition, we wanted to investigate whether an alternative scoring model with fewer options would compromise the ...

    • Loss of S100A14 expression at the tumor-invading front correlates with poor differentiation and worse prognosis in oral squamous cell carcinoma 

      Pandey, Sushma; Osman, Tarig Al-Hadi; Sharma, Sunita; Vallenari, Evan Michael; Shahdafar, Aboulghassem; Pun, Chin B.; Gautam, Dej K.; Uhlin-Hansen, Lars; Rikardsen, Oddveig G; Johannessen, Anne Christine; Costea, Daniela Elena; Sapkota, Dipak (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-23)
      <i>Background</i> - We previously showed a tumor‐suppressive function of S100A14 in oral squamous cell carcinoma (OSCC). This study aimed to examine the prognostic significance and differentiation‐related function of S100A14 in OSCC.<p><p> <i>Methods</i> - S100A14 expression was examined in 170 OSCCs from Norwegian and Nepalese populations using immunohistochemistry. Pro‐differentiation function ...

    • Tumor budding score predicts lymph node status in oral tongue squamous cell carcinoma and should be included in the pathology report 

      Bjerkli, Inger-Heidi; Laurvik, Helene; Nginamau, Elisabeth Sivy; Søland, Tine Merete; Costea, Daniela Elena; Hov, Håkon; Uhlin-Hansen, Lars; Hadler-Olsen, Elin Synnøve; Steigen, Sonja Eriksson (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-25)
      <i>Background</i> - The majority of oral cavity cancers arise in the oral tongue. The aim of this study was to evaluate the prognostic value of tumor budding in oral tongue squamous cell carcinoma, both as a separate variable and in combination with depth of invasion. We also assessed the prognostic impact of the 8th edition of the American Joint Committee on Cancer’s TNM classification (TNM8), where ...
