      Bjerkli, Inger-Heidi; Jetlund, Olav; Karevold, Gunnhild; Karlsdottir, Åsa; Jaatun, Ellen A. Andreassen; Uhlin-Hansen, Lars; Rikardsen, Oddveig G; Hadler-Olsen, Elin Synnøve; Steigen, Sonja Eriksson (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-16)
      <i>Objectives</i> - Incidence of oral cavity squamous cell carcinomas is rising worldwide, and population characterization is important to follow for future trends. The aim of this retrospective study was to present a large cohort of primary oral cavity squamous cell carcinoma from all four health regions of Norway, with descriptive clinicopathological characteristics and five-year survival ...

      Using complete information on total treatment burden, this population‐based study aimed to investigate second cancer (SC) risk in testicular cancer survivors (TCS) treated in the cisplatin era. The Cancer Registry of Norway identified 5,625 1‐year TCS diagnosed 1980–2009. Standardized incidence ratios (SIRs) were calculated to evaluate the total and site‐specific incidence of SC compared to the ...
    • Metachronous Contralateral Testicular Cancer in the Cisplatin Era: A Population-Based Cohort Study 

      Hellesnes, Ragnhild; Myklebust, Tor Åge; Bremnes, Roy M.; Karlsdottir, Åsa; Kvammen, Øivind; Negaard, Helene Francisca Stigter; Tandstad, Torgrim; Wilsgaard, Tom; Fosså, Sophie Dorothea; Haugnes, Hege Sagstuen (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-23)
      PURPOSE - It is hypothesized that cisplatin-based chemotherapy (CBCT) reduces the occurrence of metachronous contralateral (second) germ cell testicular cancer (TC). However, studies including treatment details are lacking. The aim of this study was to assess the second TC risk, emphasizing the impact of previous TC treatment.<p> <p>PATIENTS AND METHODS - Based on the Cancer Registry of Norway, ...
    • Serum miR371 in testicular germ cell cancer before and after orchiectomy, assessed by digital-droplet PCR in a prospective study 

      Myklebust, Mette Pernille; Thor, Anna; Rosenlund, Nina Benedikte; Gjengstø, Peder; Karlsdottir, Åsa; Brydøy, Marianne; Bercea, Bogdan Stefan; Olsen, Christian; Johnson, Ida; Berg, Mathilde I.; Langberg, Carl; Andreassen, Kristine; Kjellman, Anders; Haugnes, Hege Sagstuen; Dahl, Olav (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-02)
      MicroRNA-371a-3p (miR371) has been suggested as a sensitive biomarker in testicular germ cell cancer (TGCC). We aimed to compare miR371 with the classical biomarkers α-fetoprotein (AFP) and β-human chorionic gonadotropin (hCG<sub>β</sub>). Overall, 180 patients were prospectively enrolled in the study, with serum samples collected before and after orchiectomy. We compared the use of digital droplet ...
    • Surgical Complications in Postchemotherapy Retroperitoneal Lymph Node Dissection for Nonseminoma Germ Cell Tumour: A Population-based Study from the Swedish Norwegian Testicular Cancer Group

      Background - Reports on perioperative complications after postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) for nonseminoma germ cell tumour (NSGCT) are from experienced single centres, with a lack of population-based studies.<p> <p>Objective - To assess the complications of bilateral and unilateral PC-RPLND.<p> <p>Design, setting, and participants - A prospective, population-based, ...
    • Validation of a prediction model for post-chemotherapy fibrosis in nonseminoma patients 

      Gerdtsson, Axel; Torisson, Gustav; Thor, Anna; Grenabo Bergdahl, Anna; Almås, Bjarte; Håkansson, Ulf; Törnblom, Magnus; Negaard, Helene Francisca Stigter; Glimelius, Ingrid; Halvorsen, Dag; Karlsdottir, Åsa; Haugnes, Hege Sagstuen; Larsen, Signe Melsen; Holmberg, Göran; Wahlqvist, Rolf; Tandstad, Torgrim; Cohn-Cedermark, Gabriella; Ståhl, Olof; Kjellman, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-02)
      Objective - To validate Vergouwe's prediction model using the Swedish and Norwegian Testicular Cancer Group (SWENOTECA) RETROP database and to define its clinical utility.<p> <p>Materials and methods - Vergouwe's prediction model for benign histopathology in post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) uses the following variables: presence of teratoma in orchiectomy specimen; ...
